Title: Improvements in and relating to machines for roasting or drying powdered, granular or like material
IPC: A23N12/10
Filed: 1937-07-14
Abstract: 498,887. Roasting and drying granular &c. material. BAKER, G. R., BAKER PERKINS, Ltd., and ANCIENS ETABLISSEMENTS A. SAVY, JEANJEAN, ET CIE. July 14, 1937, No. 19497. [Class 58] [Also in Group XIII] Cocoa beans or other powdered or granular materials are roasted or dried in a drum 15 adapted to rotate on rollers 16 about an horizontal axis. The drum is provided with an insulating jacket 20 and is driven by a pinion 18 meshing with a gear 19 on the periphery of the drum. One end of the drum has a double-walled closure 21 through which a discharge shoot 22 passes and the other terminates in a tubular neck 24 extending into a box 27, through which hot air from the drum escapes, a packing joint 28 being provided so that the neck 24 may rotate in its connection to the box. A core member 26, also adapted to rotate in the box 27 extends through the drum and carries a number of partitioning discs 25 of which the two outer are secured to the drum while the inner ones are a loose fit therein. Inwardly and outwardly extending sets of vanes 46, 53, respectively, shaped, as shown in Fig. 5, are arranged between the discs to form pockets for feeding the material along the drum as the latter rotates. The material is fed into a charging chamber 29 at the end of the drum, through a shoot 45 and enough is lifted by a scoop 31 attached to the drum during each revolution thereof to charge one pocket of the drum this quantity of material being discharged from the scoop when it reaches its highest position through a shoot 32 and opening 33 in the end disc 25 into an inner pocket in the first compartment of the drum. As the drum rotates the charge passes from this inner pocket to the corresponding outer pocket and thence on further rotation of the drum to the next inner pocket and then the outer pocket, the movement round the compartment being continued until the charge reaches the outer pocket adjacent to the one corresponding to the first inner pocket. The vane 46 of this outer pocket is so shaped and extended that the charge, instead of passing to the next inner pocket, passes through an opening 33 in inner disc partition into an inner pocket in the next compartment : the charge then passes round the pockets of this compartment and those of subsequent compartments in a similar manner to its progress though the first compartment and is finally discharged through the shoot 34 on to an air pervious conveyer 36 over which is a hood 38. Air is drawn into this hood through the conveyer, thus cooling the material thereon, and passes through a fan 39 and conduit 40 to an air heater 41 from which it flows to the core member 26 escaping from the end thereof into the drum and then passing through staggered sets of perforations in the discs back to the neck 24 and escape box 27.

Title: Improvements relating to dynamic balancing machines
IPC: G01M1/12
Filed: 1954-07-06
Abstract: 754,602. Measuring rotor unbalance electrically. AVERY, Ltd., W. & T. (Schenck Maschinenfabrik Ges., C.). July 6, 1954, No. 19690/54. Class 40(1) The dynamic unbalance of a rotor 17 (Fig. 1) is determined by mounting it on a flange 14 on the shaft of a motor 3, the flange being attached to a fixed housing 1 by rubber supports 2 or helical springs, whereby rotary unbalance produced when the motor 3 is driving the work-piece causes oscillations in the complete assembly which are measured by electrical pickups 6, 7 or 6a, 7a, thereby determining the mass and angular positions of the unbalance masses in two compensating planes. The complete rotary assembly without a workpiece is initially balanced by attaching appropriate weights to discs 9, 10 located at each end of the shaft, using the same apparatus to determine their magnitude and position. An A.C. generator 8 attached to one end of the shaft establishes the phase relationship of the pick-up signals. The workpiece may be mounted for rotation in a horizontal plane as shown, or in a vertical plane (Fig. 7) with the pick-ups mounted on separate stands. The apparatus may also be used to determine the true axis of rotation of an irregular body.

Title: Electrical hand machine tools
IPC: H02K5/14
Filed: 1978-05-16
Abstract: The electrical components, such as coils, brush holders and switching elements, which are arranged in the housing (1), are connected in the housing (1), which consists of insulating material, by means of conductor tracks (13) which are formed directly into wall regions (12) of the housing. This simplifies the assembly of the machine. Since the ends of the conductor tracks which form contact-making elements are always located at the same point, the electrical components just need to be inserted and are then immediately electrically connected to one another. <IMAGE>

Title: An improved method of and means for setting in whirling motion a stream of fluid or the like passing through a tubular conduit
IPC: F28F13/06
Filed: 1927-07-25
Abstract: 274,910. Wade, H., (Pfoser, A.). July 25, 1927. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 27, 1927]. Metal pipes and tubes. -A stream of fluid entering or passing through a tubular conduit is set in whirling motion by deflecting the entire stream laterally, without sub-dividing it in the direction of its flow, and directing the deflected stream tangentially on to the inner surface of the conduit. The invention may be applied to liquids or gases or powdered fuel flowing through pipes or conduits and to the furnace flues of steam boilers. As shown in Figs. 2 and 4, the whirling motion of fluid passing through the pipe X is produced by a baffle having transverse members A, B closing the lower and upper parts of the pipe respectively and a longitudinal member C having a lateral opening D through which the fluid is directed tangentially against the wall of the tube and given a whirling motion. To reduce resistance to flow, the pipe adjacent to the members A, B may be stream-lined as indicated at F, G. In an alternative arrangement the member A may close the upper part of the pipe and the member B the lower part. Figs. 5 and 7 show part of a boiler flue with the baffle A, H, C, B arranged at the rear of the fire-bridge A' and with an opening D through which the gases pass tangentially to the flue wall and are given a whirling motion. A modified form of baffle has the rear closure member B inclined to provide a gradual change of direction in the gases before entering the opening D.

Abstract: 1293497 Angular bending BLAW-KNOX FOUNDRY & MILL MACHINERY Inc 9 June 1971 [10 June 1970] 19754/71 Heading B3E A rod B is coiled by guiding the rod on to a rotating conical mandrel 12 using rolls 40 which reciprocate between a position adjacent the large radius portion of the mandrel and a posi-  tion adjacent the small radius portion of the mandrel, and allowing the coils to fall on to a rotating platform 120. In operation the mandrel 12 and platform 120 are rotated by a drive-shaft 26 and the rod is fed between the rolls 40 of an assembly 14 and the surface of the mandrel. The rod is then guided by a trough 84 to a second assembly (16) after which the trough is pivoted away from the mandrel. A screw feed 46 and cylinders 74 are actuated so that the rolls 40 hold the rod against the mandrel and move between the positions shown in full and dotted lines in Fig. 3A. The coils formed on the mandrel fall on to the platform 120, the latter being lowered by a ram 140 as the coils build up. On completion of the coiling operation, the drive-shaft 26 is raised to disconnect the platform so that the mandrel can be pivoted away to clear the platform. The platform is then raised so that the coil can be removed by a pusher 173.

Title: Improvements in or relating to coin controlled vending machines
IPC: G07F5/26
Filed: 1929-06-27
Abstract: 335,914. Brecknell, Munro, & Rogers (1928), Ltd., and Dolman, H. J. June 27, 1929. Delivery of articles stored in piles; coin action, weight.-In a coin-controlled vending machine in which the insertion of a coin permits of the actuation of anv one of a plurality of delivery mechanisms as chosen by the purchaser, the coin 12, Fig. 1, passed to a pivoted shoot 10 rests on and tilts a lever 13 to close contacts 17, 18 in the leads 20, 21 of a source of electrical energy 19. When a push-button 2, for instance, of a series 1 - - 4 corresponding to article magazines 66 - - 69, is pushed in, it completes, through a contact 42, the circuit of a solenoid 24, the plunger 46 of which closes a pair of contacts 50, thereby energizing a solenoid 58 to actuate a delivery plunger 63 and expel the bottom article from the magazine 67. The plunger 46 is retained by a weighted lever 54 which is released by mechanism actuated by the delivery plunger 63 at the end of its stroke. To prevent more than one push button from being pressed in at a time, they are arranged in staggered relation and have oppositely arranged projections 1<1> - - 3<1>, Fig. 3, to pass between interlocking pivoted members 82 - - 84 When a button is pressed in, its projection acts on. an incline 82" - - 84" to rotate one of the members, the members above it being turned against the action of a spring 91 while the members below it are held against a fixed abutment by the pushbutton. The remaining push-buttons are locked by the flat ends of the rotated members and by the other members being prevented from rotation. Coin-discharging mechanism.-The closing of the contacts 50 also completes a circuit through a solenoid 61 which attracts the pivoted shoot 10 to move the coin off the lever 13 and allow it to drop through a shoot 74 to the money-box, thereby breaking the main circuit. Empty machines, locking; returning coin.--If a magazine becomes empty, a following weight 70 - - 73 falls to the bottom and actuates a corresponding switch 37 - - 40 to cut out a solenoid 23 - - 26 and make the circuit of a solenoid 31 which is energized when the push-button corresponding to the empty magazine is pushed in. The solenoid 31 attracts the shoot 10 so that the coin is moved over a slot 76 in the lever 13 and drops to a return shoot 75.

Title: Air-cooled condenser for the head product of a distillation or rectifying column
IPC: B01D5/00
Filed: 1960-06-03
Abstract: <PICT:0927918/III/1> <PICT:0927918/III/2> An air-cooled condenser for a distillation column comprises condenser-elements 8, made up of a plurality of upright tubes provided with fins, mounted above the column in vertical planes so as to form, in horizontal section, a regular polygon (an octagon in the embodiment shown), and a screw-fan 15 in the centre of the polygonal space at the upper end of the tubes.  The hot vapours pass through branches 5, distributed at uniform intervals round the head of the column, into ring-conduit 6, and then flow via branches 7 into the condenser tubes.  A stream of cooling-air is drawn from the atmosphere between the tubes by fan 15, and the stream is then discharged through diffuser 16.  The fan is driven by electric motor 24, via a variable step-down gear 25; and the speed of the fan can be regulated automatically so that the condensation-temperature of the required head-product is maintained steady despite fluctuations in the vapour-loading of the condenser-elements, or fluctuations in the temperature and/or movement of the outer air.  The upper ends of the condenser tubes are connected, via ring-conduit 13 and a pressure-regulating valve (not shown), to a suction-device or to a source of inert gas under pressure, so that the condenser may be operated at any required pressure, and this may be controlled automatically in dependence upon the temperature of the condensate.  The variable gear 25, controlling the speed of the fan, may be operated by a servomotor governed by a thermostat responsive to the temperature of the condensate in the lower end-chambers 10 of the condenser, or it may be regulated in dependence on the pressure in the upper end-chambers 9.  The condensate is withdrawn from conduit 6, part being passed as reflux to the column, and the remainder being withdrawn from the system as product.  Wind-apron 23, which is of semi-circular section, is movable on guide-rail 21 in platform 18a.  This wind-apron is automatically pressed, by natural air movement, to the leeward side of the condenser, and ensures that the rear side of the condenser is cooled, like the windward side, by the natural air movement.

Title: Improvements in or relating to a mechanism for dispensing pressure-sensitive tape
IPC: B65H35/00
Filed: 1953-07-20
Abstract: 734,645. Adhesive tape dispensers. DERBY SEALERS, Inc. July 20, 1953 [Aug. 1, 1952], No. 20046/53. Class 18. By depressing a handle 41 a length of pressuresensitive tape 25 is drawn from a supply roll 13 by a rotatable tape-feeding roller 23 and stripper roller 24 and the end A of the tape caused to project from the machine, further depression of the handle pressing the tacky side of the tape against a supporting member 53 and severing the tape while the feed roller is held against rotation. The supply roll 13 is mounted on a toothed wheel 17 rotatable on a spindle 14 fixed to the frame 10. Also pivoted on the spindle 14 is a lever 20 operated by the handle 41 and carrying rotatably the feed roller 23 and stripper roller 24, each of which has a toothed wheel meshing with the wheel 17. The rollers 23, 24 comprise interdigitated knurled discs and the tape 25 is led over the roller 23 and adheres to it. During the first part of the anticlockwise movement of the lever 20 the toothed wheel 17 is prevented from rotation by a pawl 29 and the rollers 23, 24 are therefore rotated, the roller 23 feeding the tape and the roller 24 stripping the tape from the roller 23. A projection 36 on the inner end of the lever 20 then contacts a lug 35 to raise the pawl 29 from the teeth of the wheel 17 and the wheel rotates with the lever stopping the rotation of the rollers 23, 24. A member 43 secured to the handle 41 then presses the tacky side of the tape on to a spring-pressed guard 53 protecting a knife blade 46 while a finger 42 on the handle engages the tape on the other side of the knife. Continued movement of the lever depresses the guard so that the knife 46 cuts the tape, the roller 24 being held stationary by a pawl 59. The cut end of the tape adheres to the end surface 53 of the guard 48 for ready removal. Upon release of the handle 41 the lever 20 is returned by a spring 21 allowing the guard 48 to rise and a spring pawl 34 on the lever causes the wheel 17 to rotate with the lever. A stop 33 adjustable in holes 62 permits the length of tape fed to be varied. Specification 734,646 is referred to.

Title: Semi-automatic transmission for a motor vehicle
IPC: F16H61/02
Filed: 1966-05-06
Abstract: 1,090,506. Change Speed control. FORD MOTOR CO. Ltd. May 6, 1966 [June 9, 1965], No. 20117/66. Heading F2D.  The engaging pressure 196 supplied through a manual selector valve 124 to liquid pressure operated friction clutches and brakes 74, 102, 34, 52 of a planetary change-speed gear is varied in response to accelerator pedal position during starting by a valve 118 which blocks the supply of engaging pressure at closed throttle and is by-passed by a governor valve 12 above a predetermined vehicle speed. Gear arrangement.-The planet gear comprises two sun-ring planet trains 30, 32 having a common sun 40. The carrier 36 of the first train and ring gear 44 of the second train are fast with an output shaft 42. For low ratio the ring gear 34 is clutched at 102 to an input shaft 20 and the carrier 48 of the second train is held by a brake 52 to compound both trains. For second ratio the brake 52 is released and the sun gear 40 is held by a brake 84. During 1-2 upshift the brake 52 is released prior to engagement of the brake 84 and the carrier 48 reacts on a one-way brake 66. Direct drive is provided by engaging a clutch 74 in addition to the clutch 102 and thus connecting both the sun 40 and ring 34 of the train 30 to the input shaft. For reverse the sun 40 is clutched at 74 to the input shaft 20 and the carrier 48 is held by the brake 52.  Fluid pressure system.-A main pressure regulator valve 116 is fed by an engine-driven pump 28 and supplies pressure liquid to a governor valve 120 at a pressure which varies in accordance with manifold depression 146. Below a predetermined vehicle speed the governor valve 120 directs the pressure liquid to the starting valve 118. The accelerator acts through a lever 194 on the loading spring 190 of the valve 118 so that as the accelerator is depressed the valve 118 closes an exhaust port 186 and progressively connects the servo line 196 to the line 162 from the governor valve. Servo pressure acts between differential lands 180, 182 to oppose the force of the loading spring and in forward ratios also acts on the end of the valve spool 118. Above a predetermined vehicle speed the governor valve 120 is moved left by pressure liquid supplied from an output driven governor 114 to cut put the starting valve 118 and connect the main regulator valve output 148 directly to the servo supply line 196. The manual selector valve 124 selectively connects the line 196 to lines 60, 92, 94, 110 supplying the clutch and brake servos.
