Abstract: 426,857. Wrapping-machines. BENZ, J., and HILGERS, W., (trading as BENZ & HILGERS, [Firm of]), 246, Munsterstrasse, D³sseldorf, Germany. July 27, 1934, No. 22000. Convention date, July 27, 1933. [Class 94 (i)] [See also Group V] For moulding and wrapping butter and like soft material, the butter is delivered from a hopper 2 by an intermittently-rotating screw 3 to a mould pocket 5 in a slider 7, the displaced air escaping through the perforated plate 6 during the process. The slider 7 is then operated by cam mechanism 12 to bring the mould into register with a guided ejecting- piston 10 so that the moulded block is pushed into a frame 18, taking with it a sheet of paper which has been laid in front of the member 15 and thus being wrapped on three sides by the folding action of the edges of the frame. To complete the wrapping of the fourth side to produce a packet with open ends, as shown in Fig. 4, the frame is moved downwards by the linkage 20 and trips a lever 21 so that a folding arm 22 is moved angularly against the action of the spring 24 into a position in which it folds the lower flap upwards as the frame moves downwards. Finally, the member 25 is moved downwards to fold the upper flap downwards to complete the wrapping. The package remains in the frame during the wrapping of the next package and then is pushed on to a table 26. The machine may be modified so that the frame 18 remains stationary and both members 22 and 25 move to perform the folding and means may be provided also for folding the ends of the packages. The mould may be lubricated by means of a spray supplied through one of the holes in the plate 6.

Title: Cable hauling apparatus
IPC: B25B25/00
Filed: 1973-05-09
Abstract: 1424408 Hauling cables GREIFZUG GES FUR HEBEZEUGBAU mbH 9 May 1973 [16 May 1972 7 March 1973] 22078/63 Heading B8B A cable hauling apparatus includes clamp jaws mounted in two blocks 12, 13 movable in opposite directions by two pivotable operating levers 17, 18, the jaws clamping alternately on a cable 14 passing through the apparatus and hauling the cable as they move, both operating levers 17, 18 being connected to a rotary drive shaft 50 through push-pull cables 31, 32 and crank arms 47, 49. The two crank arms 47, 49 are rotatable together but one 47, is angularly adjustable relative to the arm 49 so that one arm leads the other depending on the direction of rotation of the shaft 50. Rotation of the crank arms produces reciprocation of the blocks through the pivoted operating levers 17, 18 and flexible push-pull cables 31, 32. Each lever 17, 18 is pivoted to both blocks 12, 13 to move them simultaneously in opposite directions, one clamping the cable whilst the other is positioned for the next clamping stroke, the blocks being constructed such that the lever operated by the leading crank arm operates the clamps preventing the lagging lever from having any controlling effect on the clamps. Rotation of the drive shaft 50 in opposite directions therefore causes different crank arms 47, 49 to lead whereby the cable 14 is hauled through the apparatus in opposite directions depending on the shaft direction of rotation. In the embodiment of Figs. 5 to 8 (not shown) the two push-pull cables are connected to crank pins on a single crank arm on the rotatable drive shaft, one crank pin being slidable on the arm to form the lead/lag relationship. In another embodiment, Figs. 9 to 12 (not shown) one crank arm is pivotably mounted to the other crank arm secured to the drive shaft, and is automatically locked to the other crank arm by a cam operated pin when the shaft is rotated in the direction relating to the one crank arm leading.

Title: Improvements relating to brakes for electrically propelled vehicles
IPC: B60T11/10
Filed: 1948-08-24
Abstract: 658,290. Controlling electrically-propelled vehicles. SMITHS ELECTRIC VEHICLES, Ltd., and HEYMAN, H. W. Aug. 24, 1948, No. 22293. [Class 79 (v)] In a hydraulic braking system of an electrically propelled vehicle an electrically operated hydraulic valve is provided and the valve is interlocked with the motor control mechanism so that either the motor cannot be started whilst the valve is energized or the valve is de-energized on the motor being started, the valve being energized at will by the driver as an additional safety device to lock the vehicle brakes when required and the valve is of the kind actuated by a solenoid to prevent liquid flow and spring loaded when the solenoid is not actuated to permit liquid flow. As shown the invention is applied to an electrically propelled vehicle in which the wheels f, g are controlled by hydraulically operated brakes from a pedal e through a master cylinder c and a pipe b, the rear wheels g being also controlled by mechanically operated brakes through cables j from a hand lever h. Included in the pipe b is the electrically operated hydraulic valve a, the actuating solenoid a<SP>1</SP> of which is connected through a circuit m to a battery k<SP>1</SP> carried by the vehicle, the battery also supplying power to circuits p of the vehicle lights and auxiliaries. The motors of the vehicle are supplied with power through a circuit r from another vehicle-carried battery k. The circuits r, m are controlled by a switch s having a pair of coupled contacts t, t<SP>1</SP> and operated by the brake pedal e or by the driver by hand or foot so that the circuits r, m are not completed simultaneously, the vehicle being able to run free without either circuit being made. Energization of the solenoid a<SP>1</SP> locks the brakes in their " on position and may operate a warning light u. In a modification the current for the valve circuit is supplied through the motor control mechanism so that the valve can only be energized when the motor controller is in its " off position, depression of the pedal applying the brakes and energizing the valve and the valve being de-energized when the motor controller is moved to an "on" position.

Title: Synchronising device of a change-speed mechanism
IPC: F16D23/06
Filed: 1947-08-12
Abstract: 630,816. Claw and friction clutches. STANDARD MOTOR CO., Ltd., GRINHAM, E. G., and WEBSTER, H. G. Aug. 12, 1947, No. 22342. [Class 80 (ii)] Syncromesh clutches in motor vehicle change-speed gearing have axially-extending thrust and balking pins 28, Fig. 1, loosely located in bores 27 in the movable positive clutch member 20 and biased outwardly therein by centrifugal action, preferably assisted by spring means 35, to transmit thrust, through shouldered heads 29, from the member 20 to the movable synchronizing cone member 25 to engage the latter with its co-acting fixed member 24 and provide light initial balking of the member 20. The pins 28 have reduced ends, one 31 located as by a flange 34, and the other 30 working in a radial slot 32 in the member 25, which has limited circumferential play 21a, Fig. 4, relative to the shaft splines on which it and the member 20 slide, so that the drag consequent upon initial frictional engagement moves the pins circumferentially and wedges the heads 29 more firmly between the members 20, 25 to provide increased balking. Upon synchronism the drag balking ceases and the member 20 can be advanced to overcome the centrifugal balking and force the heads 29 to enter the bores 27, arcuate dogs 19 carried by the member 20 passing through corresponding slots 26, Fig. 4, in the member 25 and engaging dogs 18 on the fixed clutch member 12. As shown, the clutch is applied to a three-speed and reversing countershaft change-speed gear, the first-speed gear 12 being powered by a layshaft train and the member 20 being splined on the driven shaft 11 and being formed with a gear 22 meshing a reversing idler when the member 20 is moved to the right. In Fig. 2 (not shown) the invention is applied to the direct-drive and second-speed positive double clutch of this gear, each thrust pin being symmetrically outwardly biased in the movable double clutch member by a longitudinally arranged bow spring and having at either end a balking head co-acting with the respective movable synchronizing cone member.

Abstract: 225,631. Birkett, R. W. Sept. 7, 1923. Systems controlling reciprocating motion. - Two films are fed vertically in opposite directions by intermittently rotated sprockets, mechanism being provided for periodically reversing the direction of rotation of each sprocket and simultaneously moving the films laterally in relation to the optical system; the operations may be controlled by integrally driven switch gear, and etectromagnetic clutches may be provided to enable the spools serving for the time being as take-up spools to be connected to the driving mechanism. As shown in Fig. 1. films 10, 17, run between spools 12, 14 and 8, 16 respectively, over sprockets 9<a>, 13, 6, 15, the films, spools, and sprockets being mounted on a laterally movable carriage 1, 2. The sprockets 6. 9<a> are driven in opposite directions from an intermittently rotated pinion P by pinions 5<a>, 9<b>, the pinion P being long enough to engage the pinion 5<a> in each position of the carriage. Gearing is provided as shown to drive the upper sprockets 13, 15 and also the spools, magnetic clutches 22 - - 22<c> being provided in connection with the spools. The carriage is moved by solenoids 18, 19, the armatures 20, 21 of which are connected together and to the plate 2. The solenoids and clutches are connected as indicated diagrammatically in Fig. 4 to a barrel switch operated as shown in Fig. 3. The switch barrel 28 is secured to a weighted lever 27 which is engaged at the end of each film run by one or two nuts travalling on a threaded shaft'24 driven by the same means as the film mechanism. Each nut pushes the lever 27 into the vertical position, thus bringing the contact bars 29<a> on the barrel out of engagement with the fixed contacts, and breaking the circuits of the driving motor 31, of the solenoids, and of the magnetic clutches. The momentum of the mechanism causes the nut to travel sufficiently far to carrv the lever 27 over the dead point. The lever then falls to turn the barrel, thus connecting up the circuits necessary to drive the motor in the reverse direction, to traverse the carriage, and to energize the appropriate magnetic clutches. Reference has been directed by the Comptroller to Specifications 16382/13 and 201,202, [both in Class 97 (i), Optical systems &c.].

Patent GB-598420-A (GB)
Title: A process of improving vegetable oils and fats
IPC: C11B3/02
Filed: 1945-09-03
Abstract: Vegetable oils and fats are improved by treating them with a small proportion of formaldehyde or a formaldehyde polymer in the presence of a small proportion of an acid catalyst in order to remove therefrom colour-forming bodies which cause a pink or yellow colour to develop in white soap made therefrom when the soap is exposed to the atmosphere.  The purifying reaction is probably one of resinification.  The oils specified comprise soyabean, linseed, castor, and cottonseed oils, hardened by hydrogenation or unhardened. The formaldehyde polymers comprise paraformaldehyde and trioxymethylene.  The acid catalysts specified comprise strong mineral acids, such as sulphuric or hydrochloric acids, acids salts thereof, such as sodium bisulphate, and other salts having an acid reaction such as zinc chloride.  The condensed colour-forming bodies are preferably removed from the heated reaction mixtures by absorption in bleaching earths followed by filtration.  Sufficient earth may be used to effect a bleaching action at the same time. Fuller's earth, clays, infusorial earth and diatomaceous earth are exemplified.  Before filtration, alkali is added to neutralise free acid, e.g., caustic soda, soda ash, chalk or calcium carbonate.  The purification is preferably effected whilst heating the mixtures to 50 DEG -110 DEG C. at atmospheric pressure or under vacuum.  The temperature is preferably raised to 100 DEG -125 DEG C. during the separation with the bleaching earths to increase the bleaching action.  Crude oils may be purified as above but the oils are preferably preliminarily refined and earth bleached by conventional methods, such as washing with weak caustic solution, to remove gums, fatty acids &c.

Filed: 1924-09-25
Abstract: 246,193. Pupin, M. I. Sept. 25, 1924. Transmitting systems for code telegraphy. - Signalling impulses are produced by the separate energization of two field windings 13, 14 of a transmitting generator 10, the impulses due to the two windings being of opposite polarities, and the lamination of their cores and the intensity of the magnetizing force being such that the magnetic flux produced by one winding when the current in the other is interrupted has a. time constant determined by the inductance and resistance of the winding. The windings 13, 14 are connected in series with resistances 16, 29 respectively in the plate circuits of thermionic valves 17, 30, the necessary voltage thereon being supplied by a generator 15. The grids of the valves are connected to transmitter key springs 25, 35 normally resting against contacts 24, 34, through resistance 22 in the circuit of a second winding 21 on the generator 15. The positive pole of winding 21 is connected through resistance 28 to the lower contacts 27, 37 of springs 25, 35. When either key 38, 39 is depressed positive potential is applied to the grid of the corresponding valve and current flows in winding 13 or 14 to send the appropriate impulse to line. The time constant of each plate circuit is adjusted to be of the requisite order for the speed of signalling required and the resistance 28 and capacities 26, 36 are adjusted so that the time constants of the grid circuits are of the same order of magnitude. The transmitting keys 38, 39 are at opposite ends of a lever 40 but the contact springs may be actuated by any usual telegraph transmission mechanism and may be controlled by a perforated tape or by relays from received signals.
