Title: Improvements in or relating to wrapping-machines
IPC: B65B61/08
Filed: 1936-09-18
Abstract: 479,781. Wrapping-machines. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. Sept. 18, 1936, No. 25377. [Class 94 (i)] In a wrapping-machine of the type in which a pusher intermittently feeds articles into a movable carrier, carrying with it a web of wrapping material, the cutting mechanism. is mounted on a subframe adjustable relatively to the main frame in the direction of the web to vary the position during operation at which the web is cut in order to allow for variations in the size of articles in different batches to be wrapped. Pockets 2 on an intermittently rotated wheel 1 are fed with caramels from a supply channel 4 by a pusher 3. Webs of wrapping material from rolls 21, 22 pass over rolls 38, 34, 35, 36, 37 and between feed rolls 20 and a fixed shear plate 24 and a blade 25 rotated by chain and gear drive from a main shaft 28. Upon a suitable length of material being fed past the cutter mechanism in front of an empty pocket 2, the blade 25 cuts the wrapper strips and the pusher 3 pushes the caramel 31 into the pocket. taking with it the wrapper blank 32. The cutter mechanism, feed and supply rolls are mounted on a sub-frame built up of side members 9, 10 secured together by cross-pieces 11, the side members having three bosses 12, 13, 14, through which pass pillars 6 mounted in bosses 7 on the main frame 5. Between the bosses 13, 14 are mounted internally threaded worm-wheels 15 engaging the pillars 6 and rotatable by worms 16 on a shaft 17 rotated by a hand wheel 18. Upon rotation of this hand wheel, the sub-frame is raised or lowered thus increasing or decreasing the distance between the cutter mechanism and the feed mechanism so that the size of the flap left, for wrapping above and below the caramel 31 (as shown in Fig. 1), may be varied. The boss 12 may be split to receive a locking bolt 33 or a set-screw may be provided to lock the sub-frame in position. According to the Provisional Specification labels may be applied in a similar manner.

Filed: 1930-08-28
Abstract: 348,485. Refrigerating ; heat exchangers. SINGRUN, A., 1, Avenue de la Loge Blanche, Epinal, Vosges, France. Aug. 28, 1930, No. 25707. Convention date, Aug. 29, 1929. [Classes 29 and 64 (iii).] In a rotary heat exchanger 1 containing tubular elements 10 through which an external liquid 6 circulates under centrifugal force, this liquid is alone circulated through the tubes which are covered by an annular layer of an internal liquid. The apparatus is particularly intended for use as a condenser or evaporator in refrigerating machines constructed as rotary casings. An apertured diaphragm 31 forms a gutter 3 at one end of the drum containing impelling blades 4 so that on rotation the liquid in the gutter is put under pressure by centrifugal force, and maintains a circulation through the tubes 10 even if their extremities 11 and 12 are equally spaced from the axis of the drum. The gutter may dip into the external liquid or may be fed by a pipe 13 from a pocket 71 filled by the liquid splashed up by the revolving drum. The axis of the revolving chamber may be vertical in which case a central chamber is provided to which the inner extremity of the coil 10 is attached.

Title: Thermosettable sheet moulding compound and method of making
IPC: C08J5/24
Filed: 1972-06-02
Abstract: 1386665 Laminates GULF OIL CORP 2 June 1972 [11 June 1971] 25821/72 Heading B5N [Also in Division C3] A thermosetting mouldable sheet material is obtained by preparing a solution comprising (a) a polyanhydride, e.g. an olefin-maleic anhydride copolymer (b) an unsaturated mono-oxirane compound and optionally (c) an unsaturated monomer free of oxirane and anhydride groups and/or (d) an unsaturated mono-anhydride, spraying the solution together with a fibrous material such as glass fibre on to a surface, and polymerizing at least a portion of the unsaturated components without causing substantial reaction of the anhydride and epoxide groups. The polymerization may be brought about by a free-radical catalyst incorporated in the solution or by irradiation of the sprayed-on material. In the latter case component (d) is preferably present and helps to accelerate the polymerization. The resulting sheet material can then be moulded and hardened by heating to cross-link the epoxide and anhydride groups and to polymerize any remaining ethylenic groups. Thick sheets obtained by spraying more than one layer of the solution can be peeled apart along the boundary between two layers before the hardening stage if required, but they can alternatively be hardened in one piece and are then free of weakness at the layer boundaries. The solution may contain fillers and other components such as mould release agents and, especially when the first polymerization stage is to be taken to completion, plasticizers. In examples the solution contained a 1-hexane-maleic anhydride copolymer, glycidyl methacrylate, styrene and maleic anhydride together with calcium carbonate, asbestos, carbon tetrachloride and a mould release agent. It was sprayed, with glass fibres, on to a polyethylene sheet, to form 12 layers which were then covered with a similar sheet, and polymerized by treatment with an electron beam. The resulting sheet moulding compound was pressure moulded at 160 C. for 10 minutes at 280 kg./cm.<SP>2</SP>.

Title: Improvements in installation of vacuum brakes
IPC: B60T13/46
Filed: 1931-09-15
Abstract: 389,498. Fluid - pressure brakes. FREINS JOURDAIN MONNERET, 30, Rue Claude Decaen, Paris. Sept. 15, 1931, No. 25859. Convention date, May 4. [Class 103 (i).) Vacuum brake apparatus for railway wagons comprises a valve device which, when the vacuum in the train-pipe and the lower chamber of the brake cylinder is reduced in'applying the brakes, reduces also the vacuum in the upper chamber of the brake cylinder to an extent that can be adjusted automatically or manually so that the braking pressure may be varied according to the load. The device shown comprises a pair of diaphragms d<1>, d<2> forming walls of chambers c<1>, c<2> which are connected respectively to the train-pipe 6 and to the upper chamber 24 of the brake cylinder. The diaphragms actuate valves 9, 10 which control communication respectively of the chamber c<2> with the chamber c<1> and the auxiliary reservoir 4. The fulcrum o of a lever 13 connected to the diaphragms can be adjusted by a lever 15 which may be operated by hand or automatically in accordance with the load as for instance by a lever connected to an axle box and to the vehicle body. The diaphragm d<1> may be open to atmosphere on its under face and be subject to the downward force of a spring 25 equal to the normal train-pipe vacuum less the vacuum equivalent of the weight of the brake piston 3, a spring 26 exerting an upward force on diaphragm d<2> equal to this vacuum equivalent. The spring 25 may however be dispensed with and the under face of diaphragm d<1> be connected by a pipe 28 to the reservoir 4. In release conditions, the normal train-pipe vacuum is established in the lower cylinder chamber 7, in the upper chamber 24 through the ball valve 5 and in the reservoir 4 through the valve 10 which is open. When the vacuum in the trainpipe and chamber 7 is reduced to apply the brakes, the valve 10 closes and the valve 9 opens to reduce the vacuum in the upper cylinder chamber 24 to such an extent that the pressure on the piston 7 for a given reduction of vacuum in the train-pipe is a fraction a/b of the pressure which would be obtained if the maximum vacuum were maintained in the chamber 24, where a and b are the lengths of the arms of the lever 13. The vacuum established in the chamber 24 in braking is unaffected by the reduction in the volume of this chamber due to the rise of the piston 3. If the vacuum in chamber 24 falls below the determined value, the valve 10 opens to connect the chamber to the reservoir 4.

Title: Rotary regenerator
IPC: F16F15/16
Filed: 1975-06-18
Abstract: 1470644 Thermal regenerators GENERAL MOTORS CORP 18 June 1975 [5 July 1974] 25932/75 Heading F4K [Also in Division F2] The drive arrangement of a rotary regenerator incorporates both a viscous damping means 50 and also a torsion spring 43, each operatively connected between a drive sprocket 41 and the drive shaft 30 for the regenerator matrix, not shown, to lower its spring rate in order to reduce or eliminate oscillatory movements of the matrix. The drive shaft 30 is journalled at opposite ends by bearings 34 in a matrix housing 10 and has the chain driven sprocket assembly 40 journalled thereon by bushings 37 for relative rotation therewith. The spring 43 encircles the shaft and is connected at one end thereto by a radial lock tang 43a in shoulders 30e on the shaft and at the other end is connected to the sprocket 41 by a pin 45 passing through the sprocket. The pin protrudes into a housing 51 of the damping means 50, which means encircles the splined flanged end of the shaft, to which it is connected by a retainer ring 48 and to the sprocket 41 by a pin 45. The housing 51 and a cover plate 52 combine to provide an annular recess 55 for a damper disc 53 and a viscous fluid. Clearance of the disc at opposite sides relative to the housing and plate allows rotation of the disc which is limited by the capacity of the spring and dampened by the action of the fluid, which dampening action also exists against any differential motion between the matrix and drive shaft created by any friction-induced oscillatory conditions of the matrix.

Title: Kitchen appliance for reducing raw vegetables into very small pieces
IPC: B26D3/26
Filed: 1950-10-25
Abstract: 676,180. Cutting vegetables. SIDES SOC. ANON. Oct. 25, 1950 [Oct. 27, 1949; Nov. 23, 1949; June 19, 1950], No. 25946/50. Class 5(i) The hand rotated cutters 11 of a vegetable cutter are designed to have a progressive scissors-like actior with upstanding stationary cutters 10 with which they remain in contact, such action being obtained by suitably shaping the rota ted cutters 11, such as angular in Figs. 1 and 2 curved as in Fig. 3 or by making the stationary cutters 10 non-radial as in Fig 4. A spring 9 urges the movable cutters down on the bottom cutters 10, the reaction being taken by a diametrical bar 5 which can be removed from its securing hooks 4 to take out the spindle 6 and the cutters 11. Openings 12 allow the cut material to pass through. The effective area of such openings 12 is adjustable by co-operating slots 14 in a sheet metal disc 13, Fig. 5, underneath which can be slid round and clamped by a screw 15 in a slot 16 to the bottom 2. In a modification, Fig. 6, the container comprises bayonet jointed upper and lower parts 1 and 2 the part 1 being of reduced diameter to facilitate hand gripping. The top of 1 has openings to drop in the vegetables. The cutter 11 is of bent cross-section and slopes away from the container wall, and is rotated by an arm 22 through a flexible rod 25. The arm 22 has a finger hole 26 by which it can be rotated. In a modification of the internal fittings of Fig. 6 or Fig. 1 both sets of cutters are mounted on the same rotated spindle 6 but the upper cutters 28 are held stationary when they engage a stop projecting inside the container body while the lower cutters 1 continue to rotate with the spindle. This provides a preliminary cutting between 28 and 11, the final cut being done between the lower edges of 11 and the cutters 10 in the bottom of the container. Fig. 13 shows a set of multiple cutters on the spindle 6, alternate cutters 28<SP>4</SP> and 28<SP>6</SP> being held stationary by similar stops while the other cutters produce multiple cutting on both their top and bottom edges. Fig. 15 shows stationary cutters 28<SP>8</SP> and movable cutters 11 both provided with teeth. The bottom of the container may have comb-like exit slots 12<SP>1</SP>, Fig. 17, additional to the radial slots 12 in front of the cutters 10. Such slots 12<SP>1</SP> provide tongues 34 which vibrate during cutting to release the cut particles more easily. The tongues 34 are bent upwardly but their tips are lower than the edge of the stationary cutters 12. The height of the tongues determines the fineness of the cut particles.

Void [Published under Sect. 91 of the Acts]. [Class 40 (v).] An intervalve coupling stated to be suitable for radio or audio frequencies comprises a choke Ls, in the plate circuit of valve R1, having an inductance between one and two times that of the primary L1, of a coupling transformer fed through a condenser C1, and the damping R/L of the circuit R1, C1, L1, is made about equal to its resonant frequency, 1/#LC. This resonant frequency, in the case of an audio-amplifier, is made in the region of 100 cycles per second and a coil L3, condenser C3 and optionally an additional condenser C4, tuned to about 7,000 cycles per second may be added, as shown, to increase the high-frequency response and provide a sharp cut-off. The invention enables a transformer of ratio as high as 10 : 1 to be used with a valve of 10,000 ohms internal resistance, and the theory underlying the choice of the values for the various components is developed in the Specification, suitable values being mentioned.

Filed: 1957-08-19
Abstract: 812,862. Regulating; spray carburetters. GENERAL MOTORS CORPORATION. Aug. 19, 1957 [Sept. 10, 1956], No. 26083/57. Classes 7(3) and 7(6) In a multicylinder engine which operaates at part load on less than the maximum number of cylinders, the fuel supply is switched from one group of cylinders to another, either repeatedly or on successive operations at part load, so that any one cylinder is not continuously operative. In Fig. 6 two groups of four cylinders are fed with fuel from a metering device 59 with a metering chamber 61 connected through passage 72, 73, to pipes 86, 87 leading to distributers 88, 89, feeding the cylinders in each group, the metering chamber 61 having a by-pass valve 58 which is controlled in accordance with air flow in the induction pipe so that less fuel is by-passed back to the pump inlet 69 as the air flow increases. The passages 72, 73, contain shut-off valves 77, 78 which when pulled down by solenoids 93, 94, bypass the fuel from the pipes 72, 73, back to the pump inlet to put one or other of the cylinder groups out of operation. At idling, Fig. 7a, all cylinders are in operation but when the accelerator pedal 102 is depressed a predetermined amount, Fig. 7b, contacts 112, 113, are closed to energize one of the solenoids, e.g. 93, Figs. 6 and 8, to put one group of cylinders out of operation, and to energize a solenoid 111 which shifts a rod 104, carrying the pivot of a link 99, to the left to further open throttle valve 27 a predetermined amount which increases the air flow and produces an increased fuel supply to the four cylinders in operation. A sequential switch 117, Fig. 8, ensures that the current is supplied alternately to the solenoids 93, 94, so that the engine does not always operate on the same group of cylinders at part load; the frequency of alternation may be rapid or each time the engine changes from eight to four cylinder operation. Further depression of the accelerator pedal opens the throttle valve fully with the contacts 112. 113 still closed so that maximum torque on four cylinder operation is obtained. On still further depression of the pedal 102, contacts 112, 113 are broken, Fig. 7c, so that solenoids 93 and 111 are de-energized, permitting valve 79, Fig. 6, to rise to restore the fuel supply to its associated group of cylinders and releasing-shaft 104 so that the throttle valve 27 closes slightly to give the same torque from eight cylinders as was previously obtained from four. Further movement of the accelerator pedal opens the throttle valve fully for maximum torque from all cylinders. The pivot of link 99, Fig. 7, moves between stops 106, 107, of which the stop 106 may be adjusted by a centrifugal governor. A thermally operated switch prevents the operation of the solenoids 111, 93 and 94 at low temperatures. The metering bypass valve 58 is controlled by a diaphragm 41 controlled by the pressure drop in a venturi 31 in the intake pipe. The fuel from the metering device 59 is delivered to nozzles 26 situated adjacent the air intake valves 21.
