Title: Pallets and pallet-like bodies for road vehicles
IPC: B60P1/02
Filed: 1959-12-29
Abstract: 927,361. Pallets for handling loads. J. D. BILLINGTON. March 29, 1961 [Dec. 29, 1959], No. 36676/59. Class 78 (4). A pallet-like vehicle body, Fig. 1, has upper and lower load platforms and means are provided for raising and lowering the upper platform. The upper platform is attached to four nuts, one at each corner, which move up and down screws located within uprights 12. The screws are rotated by a chain 32, Fig. 3, which passes round sprockets 31 on the screws and is driven by an hydraulic motor 39 through a reduction gear-box 38. Hydraulic power, supplied through lines 41, is derived from a power take-off on the vehicle carrying the pallet. The load, e.g. motor cars, is secured by hooks and hawsers wound on ratchet-controlled shafts 46. Both upper and lower platforms have retractable loading ramps 50, Fig. 1, comprising hinged flaps 51 the inner one of which may be folded back against the edge of the platform to form an incline as shown. The pallet is locked on the chassis of the carrying vehicle by rollers which engage and bear down on wedgeended bars 54, Fig. 2. The rollers are mounted on shoes which are moved inwards by worms. In addition, hook-like members on the chassis may be rotated into engagement with the pallet. Detachable ramps are provided to allow cars to be driven on to the pallet, the upper platform being loaded in its lowered position and subsequently raised. The pallet may be mounted on a trailer in which case bridging members are used between the trailer and towing lorry to allow cars to be driven over the trailer and on to a pallet on the lorry. Apertures 53 receive the tines of a fork-lift truck.

Title: Improvements in or relating to methods of forming conducting coatings on walls extending into insulating supports
Inventor: COLBORNE RONALD HENRY
IPC: C23C4/00
Filed: 1956-12-04
Abstract: 854,881. Coating with metals. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 3, 1957 [Dec. 4, 1956; Feb. 1, 1957], Nos. 36983/56 and 3499/57. Class 82(2) [Also in Group XXXVI] A method of forming a conductive coating on a wall extending into an insulating support comprises providing a covering for the support, apertered to expose the wall, providing a conductive coating which will adhere to the wall, and subsequently removing the covering to leave the conductive coating on the wall in electrical contact with a conductor provided on the support. The wall may be formed either before or after covering. In one embodiment (Fig. 2c), an insulating support 7 having a conductor 8 and an aperture 9, has a rubber mask 10 over its surface which leaves the aperture wall exposed. The wall is first sprayed with an adhesive and then with a thin conductive coating of silver 11 which is used as an electrode for plating a layer of copper 12. The silver coating may be formed by simultaneously spraying a solution of a silver compound e.g. silver nitrate, and a reducing agent. The mask is subsequently removed (Fig. 2d) leaving the portions of the coating 11 and the layer 12 on the aperture wall in electrical contact with the conductor. In other embodiments Figs. 1a to 1c, not shown) the mask may be replaced by a coating, such as wax, shellac or gum and the aperture made after applying this coating. The layer of copper may alternatively be sprayed on to the silver. Specification 854,880 is referred to:
Patent GB-862012-A (GB)
Title: Improvements relating to stacking apparatus
IPC: B65G57/00
Filed: 1955-12-28
Abstract: 862,012 Stacking-machines. LISSIMORE, J. P. March 28, 1957 [Dec. 28, 1955], No. 37060/55. Class 94(1). Crates 14, 15 are withdrawn from a conveyer 12 by a horizontally and vertically moving carriage 34, Fig. 1, having bearers 43 which can be projected horizontally to support the crates, and the crates are then lowered to a position immediately above the last layer of a stack of crates carried on a platform 55 and are held above the stack while the bearers 43 are retracted. In the machine illustrated the stack can be formed in this way on a pallet placed on a turntable 55 which is turned through a right angle after each course is completed. The bearers 43 are projected by rams C6 through slots 16 in the side members of the conveyer 12, and a vertically travelling carriage 25 on which the carriage 34 is mounted is moved on its guides 18 by a pneumatic ram C1 in its hoisting rope 22 to cause the bearers 43 to lift the crates. The crates are then held on the bearers 43 as the carriage 34 is retracted by pawls 48 pivoted on a member 37 of the carriage 34 and formed with camming surfaces 50, Fig. 3, which ride up over the corner 51 of each crate as the carriage 34 approaches it and then fall into engagement with the inside of the crate. Alternatively the pawls 48 may be sufficiently long to engage the remote outside face of the crate, and they may be raised by cams. The carriages 34 and 25 are then lowered by winding gear 20 until a stop 120 on the carriage 25 abuts a lug 111a, 111b or 111c adjustably mounted on a shaft 110 which is in consequence moved endwise to operate a valve 117. The shaft 110 is turned to determine which of the three lugs 111a, 111b, 111c shall engage the stop 120, each time a course of crates has been laid. The carriage 34 is then moved to the right in Fig. 1 until the crates engage either a fence 91 or a row of crates previously added to the stack. When this happens a spring biased member 107 on the carriage 34 is depressed by the crates to operate a vlave V6, Fig. 3, causing the bearers 43 to be withdrawn, while the carriage 34 remains stationary, so that the crates are deposited on the stack. Each row of crates laid is counted by a ratchet wheel (not shown) operated by a pneumatic cylinder and carrying cams which, after each course of crates is completed, cause the shaft 110 to be turned, and the fence 91 to be withdrawn from the stack while the turntable 55 is turned through a right angle. Should the rope 22 holding the carriage 25 break, the carriage is prevented from falling by a pawl 145, Fig. 15, biased about its pivot 147 on the carriage 25 to engage a fixed chain 143 but normally held out of engagement with the chain by a connection 146 to the rope 22.

Title: Calorimetric flow monitor
IPC: G01F1/698
Filed: 1975-09-09
Abstract: 1488179 Measuring fluid-flow electrically ELLENBERGER & POENSGEN GmbH 9 Sept 1975 [5 Oct 1974] 37100/75 Heading G1N(A) A calorimetric flow monitor comprises a measuring head 1 wherein pins 10 screwed into insulating block 5 each contain a thermistor 14 and one of the pins a heating element 16, a bridge circuit 18 including the thermistors, and first and second differential amplifiers 27, 28, the first amplifier 27 determining changes in flow-rate, the second amplifier 28 monitoring breakages in a circuit for supplying the heating element and in conductors connected to the thermistors. The bridge is arranged to balance with a temperature difference of 10C between the thermistors which is achieved by adjustment of the heating current with potentiometers 23, 24. If the flow past pins 10 is slower than the set threshold the output signal of amplifier 27 becomes positive relative to a reference voltage obtained from the circuit comprising Zener diodes 36, 37 and diode 38. This renders transistors 41, 42 conductive and a red light emitting diode 39 lights up. Similarly if the flow is faster than the set threshold the output of the amplifier 27 is negative and a green light diode 40 lights up. The amplifier 27 output is also compared with the reference voltage by amplifier 30 the output of which is connected to a flow monitoring relay 31. The output of amplifier 28 is fed to a threshold switch comprising a Zener diode 32 and transistor 33, the threshold switch exciting a malfunction relay 35 via transistor 34. The metal pins 10 are of stainless steel or chemically resistant plastic, the heating element is wound on a copper sleeve 12, and the pin is filled with casting resin of good heat conductivity.

IPC: H01F29/06
Filed: 1956-12-10
Abstract: 830,224. Boosting transformers. BRENTFORD TRANSFORMERS Ltd. Dec. 9, 1957 [Dec. 10, 1956], No. 37653/56. Classes 38 (2) and 38(4). A voltage regulator comprises a main tapped transformer winding 1 with offload contacts 7, 8 movable stepwise alternately engaging with alternate taps which are connected through loadbreaking contacts 9, 10 to the centre-tapped secondary winding 6 of an auxiliary transformer, the primary winding 4 of which is supplied from a secondary winding 2 preferably on the same core as winding 1 which feeds a control winding 3 having two on load contacts 11, 12. With contact 8 supplying the load through contact 10 and winding 6, and contacts 11, 12 in the minimum voltage position, moving the contacts 11, 12 will increase the voltage to the mid point between that given by taps 7, 8. Contact 9 may now be closed but no change in the output voltage will take place. If contact 10 is now opened, contact 7 will supply the load, but as the fluxes in the transformer primary and secondary windings 4, 6 are now in opposition the output voltage will still not be effected. The output voltage may now be increased by moving contacts 11, 12 towards the other extreme position. The winding 3 is arranged to give a buck or boost equal to half the difference between the taps on the main winding. A differential gear and mechanical and electrical interlocks are provided to ensure that contacts 7, 8 can only be moved while the relevant contacts 9, 10 are opened, and that the latter contacts can only be operated when contacts 11, 12 are in their extreme positions.
