Abstract: 880,114. Charging and discharging storage chambers. BOBY Ltd., ROBERT. Sept. 11, 1959 [Nov. 20, 1958], No. 37368/58. Class 78 (4). An even layer of material 14 (Fig. 1), is laid in a chamber A by a wall 32 which can be moved along the length of the conveyer and which carries a spreading device 11. The wall may also carry a conveyer 26 for discharging the container. In the form illustrated the device 11 is an unenclosed screw conveyer which receives material through any of several closable hoppers 15 (Fig. 2), spaced along the container and fed by a screw conveyer 6. The wall 32 (Fig. 1), and screw 11 are mounted on a carriage 8 propelled along rails 10 by rollers 9 which are driven either under manual control from a seat 23 or automatically, under the control of devices which sense when the material at the end remote from the hoppers 15 has reached the level of the screw 11. A trimming blade 13 mounted behind the screw 11 may be capable of adjustment to provide a thinner level of material. The unloading conveyer 26 is also a screw and delivers the material from both sides of the container to a slot 28 (Fig. 2), in the floor through which the material falls to a conveyer 27. The slot 28 is normally closed, and a sliding partition 25 (Fig. 1), prevents material reaching the conveyer 26 while the container is being loaded. The invention may be applied to chambers for treating grain or malt.

Title: Improvements in and relating to gramophones
IPC: G11B17/02
Filed: 1946-12-20
Abstract: 624,732. Automatic gramophones. GARRARD ENGINEERING & MANUFACTURING CO., Ltd., and OFFEN, F. J. Dec. 20, 1946, No. 37552. [Class 40 (ii)] In an automatic gramophone for playing both sides of records, an arm 1 for lifting and inverting a record has a hookshaped pin 3 for engaging the central hole of the record, and a sliding member 10 having engaging portions 12 and 15 for engaging records of different sizes. When the sliding member 10 is withdrawn to its fullest extent, by means of a pull-rod 25, cranked lever 26 and push-rod 29, the engaging portion 15 falls by gravity to the position shown in Fig. 3, so that a record of the larger size may be engaged. When a record of the smaller size is to be engaged, the extra movement of the sliding member 10 brings the sloping end 21 of the engaging portion 15 into contact with the pin 22 so that the portion 15 is moved to the position shown in Fig. 1. The arm 1 is rotated for inverting a record by means of a pinion 30 and a rack on a control rod 32, and is moved horizontally to and from the playing position by means of a pinion 38 and rack 36. When the arm 1 is in a position to grip a record from above, the engaging portion 15 falls by gravity to engage a record of the smaller size but will be pushed up by a record of the larger size.

Title: Improvements in electrically driven sewing machines
Inventor: PALMER GEORGE WILLIAM
IPC: D05B69/22
Filed: 1961-10-19
Abstract: 947,200. Controlling clutches &c. LIGHT'S LONDON Ltd. Sept. 26, 1962 [Oct. 19, 1961], No. 37572/61. Heading F2L. [Also in Division D1] A pulley 25, journalled on the shaft 3 of an electric motor 2, is coupled by a belt 27 to a pulley 28 fixed to the arm shaft 6 of a sewing machine. A driven clutch element 35, splined to a boss 33 of pulley 25, is engaged with a driving clutch element 36, fired to shaft 3, upon energization of a clutch coil 38. A first brake element 50, splined to a boss 51 of pulley 28, is engaged with a shroud and fired brake element 56 upon energization of a brake coil 55. A cam 60, fired to shaft 6, co-operates with a pivoted follower 16 spring-biased thereagainst, to permit closure of contacts 64 and 65 when follower 61 engages a flat surface on cam 60. The presser bar 13 carries a lateral bar 75 which, when the presser bar is raised by a lever 19' permits a contact arm 76 of a micro-switch 74 to engage a contact 77, and when the presser bar is lowered moves arm 76 into engagement with a contact 78 of switch 74. A tapping from a field winding 70 of the induction motor 2 is connected to the input of a rectifier 73, to the output of which is connected the clutch coil 38 in series with the contact arm 76 and contact 78. Two parallel circuits, containing respectively a lamp 80 fixed on the machine arm 5 and the brake coil 55 connected in series with the contacts 64, 65, are connected across the output of rectifier in series with the contact arm 76 and contact 77. The arrangement is thereby such that when the presser bar is lowered, clutch coil 38 is energized to drive the machine, and when the presser bar is raised, lamp 80 is lit and the machine continues to run until contacts 64, 65 close to energize the brake coil 55, when the machine stops with the needle raised. The contacts 77, 78 are shunted by a circuit containing a variable resistor 81 mounted on the arm 5, and a micro-switch 84 which is mounted above switch 74 and has a contact arm 82 moved momentarily into engagement with a contact 78 when the lever 19 is lifted fully. The latter operation is performed if the needle does not initially stop in the fully raised position, and has the effect of momentarily re-energizing coil 38 via resistor 81 to drive the machine slowly until the contacts 64, 65 close. Resistor 81 is so adjusted as to ensure slipping of the clutch if coil 38 is energized when the contacts 64, 65 close. Specification 923,389 is referred to.

Abstract: 350,880. Alternating-current commutator motors. FAIRWEATHER, W., 65, Chancery Lane, London.-(Singer Manu. facturing Co. ; Elizabeth, New Jersey, U.S.A.) April 8, 1930, No. 37641. Divided on 345,828. [Class 35.] Brush-holders.-In a commutator motor adapted to start as a repulsion motor and to run as an induction motor, the brush lifting mechanism is spring actuated and is held in the starting position, with full power stored in the spring, by a latch which is tripped by speed responsive means. A ring 6 fixed to the shaft 5 has cylindrical slideways 7 for weights 8 having conical ends 9. A dished disc 10 is slidable on the shaft against the action of a spring 13 and is caused to move towards the commutator by the interaction of the conical weights with the conical portion 11. Studs 15 fixed to the disc 10 pass through apertures in a commutator short-circuiting disc 16 and carry compression springs 17. The brush holder boss 19 carries a tube 21 inside a bushing 20 and external connection to the tube is made by a terminal lug band 22. The brush 25 is secured to a shank 24 slidable in the tube 21. The brush shank 24 has a longitudinal slot 32 closed at its upper end in which engages a pin screw 31. The pin fixes the bushing 20 and brush tube 21 in the boss 19 and prevents the brush shank 24 from turning whilst permitting sliding movement. The shank is also formed with a shoulder 34 for engagement with the brush-lifting lever 35 which is fulcrumed on an ear 37 extending from the boss 19. The brush lifting-lever has a short arm 38 near the rim 12 of the disc 10 and carries a spring 39 coiled about the fulcrum screw 36. A latch lever 41 pivoted on the ear 37 has a shoulder engaging a pin 43 on the lever 35 and detains the lever 35 in the starting position shown with full power stored in the spring 39. At starting, outward movement of the weights 8 causes the disc 10 to move to the left, compressing the springs 13, 15. After the short-circuiting disc 16 has contacted with the commutator 4, further movement of the disc 10 causes the rim 12 to strike the latch 41, thereby releasing the lever 35 which is forced by the spring 39 to lift the brush. In the running position, the rim 12 rotates in a gap between the arm 38 and latch 41 without touching either. When the motor stops, the spring 13 moves the disc back to reset the lever 35 in the starting position.

Abstract: 965,536. Cooling reactors. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Nov. 2, 1960 [Nov. 24, 1959; Jan. 29, 1960], No. 37682/60. Drawings to Specification. Heading G6C. A pressurized containment vessel for a water cooled reactor and its primary coolant circuit is divided into two parts by a horizontal partition in which are apertures closed by bursting disks. The reactor and primary circuit are in the lower part of the vessel, while the upper part contains a layer of water above the apertures; steam released by bursting of the primary circuit will fracture the bursting disks and bubble through the water, thus reducing the steam pressure. If the reactor has an associated heat exchanger for emergency cooling by natural connection of coolant or for condensation of steam on failure of the coolant circulation system, this heat exchanger may be immersed in the layer of water.

A transistor 7, 8, and/or 9 is subjected to a temperature to be measured and its leakage current controls the collector current in an amplifying transistor 1, whose base is connected to the emitters of transistors 6, 7, 8 and which controls a meter 2, alarm relay 3, or a recorder. In a differential temperature measuring arrangement, a compensating temperature sensitive transistor or transistors (not shown) is or are arranged at a reference temperature and connected to the base circuit of the amplifying transistor 1 to supply a current in opposition to that from transistors 7, 8, 9. A plurality of the transistors 7, 8, 9 may be used as a temperature-responsive fire alarm system, and the base circuit of each transistor may include a photo-resistor 10,11,12 sensitive to the light of a flame, the effect of a drop on resistance of a photo-resistor due to a flame occurrence being such as to override the temperature responding operation. To avoid the photo-resistors causing operation of the relay 3 in response to permissible light such as daylight, a further photo-resistor 14 is connected in the voltage bias supply circuit and made responsive to the daylight but not flame-light, so that the base-bias voltage of the transistors 7, 8, 9 is automatically adjusted to null the effect of the daylight-induced drop in resistance of the photo-resistors 10, 11, 12. The bias voltage supply includes a Zener diode 15 and a potentiometer 13.

Abstract: 840,530. Reels for cables &c. GENERAL ELECTRIC CO. Ltd., and ARNOLD, G. H. Dec. 4, 1958 [Dec. 4, 1957], No. 37763/57. Class 99(2). A portable reel arrangement comprises a reel or drum 1 on which cable, wire, rope or the like may be wound, a framework including a carrying handle 7 and within which or on the reel is mounted, a friction brake 8, 11 normally arranged to prevent rotation of the reel, and means disposed adjacent the handle for releasing the brake to allow rotation of the reel. When the device is lifted by the handle the means for releasing the brake may be operated, whilst, if that means has been operated, release of the handle causes the brake to be re-applied so that if the reel or drum is rotating the latter is progressively braked to rest. As shown, the wood reel 1 is mounted in a frame of aluminium tubing formed of parallel, spaced apart members 3 joined by members 4. Mounted externally of one face of the reel is an annular member 8 of bronze and generally V-shaped in crosssection, a wedge-shaped part 11 of cast iron being urged by a spring 12 between the arms of the " V " of the member 8 ; the part 11 is secured to a slidable member 10 actuated by a lever 13 pivoted within the tubular handle 7 and connected to and operated by a lever 15 pivoted on the handle. The inner end of a cable 2 wound on the reel is connected to a terminal block mounted at one end of the reel axle 5, and rewinding of the cable is provided for by a foldable handle 17 attached to the other end of the axle. Specification 819,140 is referred to.

Abstract: 1,084,927. Power steering systems. FORD MOTOR CO. Ltd. Aug. 26, 1966 [Oct. 11, 1965], No. 38376/66. Heading B7H. [Also in Division F2] A motor vehicle power steering system includes a pump assembly comprising a positivedisplacement pump 25 and a by-pass valve 45 for by-passing part of the pump output to the pump inlet to control flow through a discharge outlet 17 from the assembly in such a way that the flow from the discharge outlet is reduced when the pump output reaches a certain value. A valve chamber 92 receiving the pump delivery through an inlet 93 contains a spring-loaded valve spool 95 which controls the size of a bypass orifice 106 connected to the pump inlet and carries a metering rod 101 controlling the size of a discharge orifice 96 connected to the outlet 17. The end of the spool 95 remote from the inlet 93 is subjected through a passage 105 to the pressure downstream of the discharge orifice 96. As the pump output rises with engine speed, a constant diameter portion 1 of the rod 101 first occupies the discharge orifice 96 so that delivery from the outlet 17 increases with speed until the spool 95 begins to uncover the by-pass orifice 106 and delivery is maintained constant. At a predetermined pump output, a tapering portion 104 of the rod 101 begins to move through the discharge orifice 96 to provide a progressively decreasing delivery until a larger diameter portion 103 of the rod occupies the discharge orifice 96 and delivery remains constant at a reduced rate. A spring- loaded ball-valve 51 relieves excess pressure at the outlet 17. The pump 25 and valve housing 36 are mounted in the pump housing 11 on a pair of dowels (Fig. 3, not shown) and are urged into sealing engagement with each other and the end wall of the housing 11 by a pair of springs (Fig. 2, not shown). A reservoir 14 surrounding the housing 11 includes a return flow connection 16 and communicates with the pump inlet through an opening 61.

Abstract: 1381966 Automatic titration METTLER INSTRUMENTE AG 17 Aug 1972 [1 Feb 1972] 38504/72 Heading G1N In an automatic titration apparatus in which the titrating agent is supplied in a series of individual amounts to the specimen to be tested a respective next individual amount of titrating agent is supplied only when the differentiated output from the sensor measuring a titrating parameter falls below a predetermined value and preferably remains below the value for a predetermined time. A titration vessel containing bivalent iron to be tested is provided with Pt/Ag AgCl measuring electrodes and the permanganate titrating agent is added in 0À1 ml quantities from a burette controlled by a driver including a stepping motor and a variable frequency pulse transmitter. The delivery speed is set at remote control 17 by controlling the frequency of the pulse transmitter and then the apparatus is started. The potential as measured by electrodes 11 is amplified and differentiated with respect to time in amplifier 14, and then  passed through an analog amplifier 28, the sensitivity of which can be set, to a threshold switch 29. As shown in Fig. 6 when the differentiated value of the protential E<SP>1</SP> falls to the point corresponding to a threshold -G of the switch 29 timers 30 are set in operation. The timers delay is composed of one time interval tint which depends upon the maximum valve M1 reached by E<SP>1</SP> and another time interval text which is set depending upon the required sensitivity of the apparatus. After this interval of tint + text then if E<SP>1</SP> still lies in the region between +G and -G of the threshold switch a signal is passed to data transfer 31 which causes the potential supplied by amplifier 14 to be indicated on a digital indicator and recorded on a chart, and an analog digital reset 32 to be triggered. The reset 32 passes a signal to an increment pulse counter 33 which passes a starting signal to the burette driver 13 to cause a further volume of titrant to be applied. If however the value of E<SP>1</SP> passes outside the threshold region before the time interval tint + text has passed both timers 30 are reset and the delay begun again, and no signal is applied to the data transfer 36. The process is repeated until the value of E<SP>1</SP> lies between -G and +G at the end of the delay tint + text. The titration process may be conductometric, voltametric, amperometric, photo-metric or thermometric. The titrating agent may be generated electrolytically.
