Title: Improvements in or relating to road vehicles to facilitate loading and unloading
IPC: B60P3/10
Filed: 1937-05-26
Abstract: 496,549. Vehicle fittings for loading. BROCKHOUSE & CO., Ltd., J., and DEAR, A. T. C. May 26, 1937, No. 14576. [Class 78 (iv)] [Also in Group XXXII] In road vehicles fitted with movable floors which can be tilted to form a loading ramp and in some cases may slide rearwardly before being tilted, roller tracks are provided on the floors and a winch is arranged to draw a flexible member over an elevated pulley on the frame so that the floor can be moved, or the load moved over the floor. Fig. 1 shows a two - wheeled trailer adapted to load a motor boat, in which the floor tilts only. The floor 21 is pivoted at 20 and tilted by the cable 25 running to the hand-operated geared winch 27. Shock-absorbers 32 cushion the movement. The hook 26 is then attached to the load and the latter is drawn over the roller bed 22 on the tilted floor and lashed at 33, 34. Paying out the cable then moves the floor into the horizontal position under the weight of the load and allows screw locking- pins 31 to be manipulated to fix it in position. In the preferred construction two roller beds are used, one situated at each side of the floor, with an intervening clear space. Handoperated brake gear 18 is provided for the road wheels of the trailer, and the usual jacks 15 also are provided. Fig. 5 shows a fourwheeled trailer in which the floor 44 both slides and tilts. The rear end of the floor rests on two sets of side rollers 48 carried by pivoted brackets mounted on the frame of the truck, while the front end carries a pair of rollers 46 mounted on a centrallypivoted bar 62, thus giving a 3-point support for the floor in its horizontal position. The bar 62 can swing in a vertical plane within the limits allowed by the members 64, thus preventing distortion of the vehicle frame being transmitted to the load. Two handoperated winches are used, one 56 for hauling the load by the cable 43, and the other 54 for hauling the floor by the endless cable 53. Provision may be made for coupling the winches and actuating them simultaneously. Side rollers 60 guide and prevent rocking of the load. Brackets 57 hold the rollers 46 down during transport and locking-means as in Fig. 1, is applied to the floor near the rollers 48. A large roller 50 engages the ground when the floor is acting as a ramp.

Title: Improvements in or relating to monocable ropeways and to rope grips for such ropeways
IPC: B61B12/06
Filed: 1959-04-29
Abstract: 898,716. Rope grips for mono-cable ropeways. BRITISH ROPEWAY ENGINEERING CO. Ltd., and BUNCE, A. R. May 17,1960 [April 29, 1959], No. 14658/59. Class 78 (2). In a mono-cable ropeway, a support 13 carries a pair of jaw members 20, 22, arranged so that when the support is brought downwardly on to the rope 10, the latter can enter between the jaws which move upwardly relative to the support 13 and also close together to grip the rope 10. According to the invention, an operating element 34 on movement relative to the support 13 causes the jaws 20, 22 to be closed together to grip the rope, and means are provided responsive to the angular movement relative to the support 13 of a load-carrying hanger 11, for moving the element 34 relative to the support 13. Thus the grip is tightened as the hanger is angularly displaced from a datum position. The jaw 20 is pivotally mounted at 21 to the support 13 and the jaw 22 is pivotally mounted at 23 to the jaw 20 and has an arm 35 which extends to a position adjacent the element 34. The latter is carried by a sleeve 33 resiliently mounted by a rubber bush 32 on a rod 12 which is rigid with the hanger 11 and is journalled in the support 13. As shown, there are two pairs of jaws 20, 22 mounted on each support 13, there being diametrically opposed projections 34 on the sleeve 33 in respect of each of the jaws 20 of the two pairs of jaws. Adjustment of the jaws to suit the size of the rope 10 may be effected by means of a bolt 26 and nuts 27. When the rope is inclined at more than 20 degrees to the horizontal due to the resulting angular displacement between the support 13 and the arm 11, one or other projection 34 picks up the corresponding jaw 20 to increase the grip of the associated jaws. The support 13 carries a pair of parallel longitudinally-extending plate members 14 which engage a holding down sheave (shown in dotdash lines at 17 in Fig. 3). The members 14 also carry a pair of sheaves 15 for supporting the carriage when it runs on to a fixed rail track.

Title: Improvements in or relating to the coating of ferrous metal bases with metal
IPC: C23C2/02
Filed: 1943-09-07
Abstract: A process for coating a ferrous metal base with a protective metallic coating that consists in heating the base metal to a temperature slightly above the melting temperature of the coating metal in an atmosphere of hydrogen, and then immersing the said base metal in a bath of coating metal while still in the said gaseous atmosphere, said base metal temperature being maintained constant at a point higher than the melting point of the said coating metal after it has left the bath, thus forming a smooth, continuous, firmly adhering coating on the said base metal.  About 1 per cent of another element adapted to alloy with the coating metal and the base metal may be added to the coating bath.  The Specification refers to the coating of iron with silver by the said process in which iron is heated to about 1000 DEG  C. in a hydrogen atmosphere prior to coating in a bath consisting of silver or of 99 per cent of silver and 1 per cent of a copper phosphorus alloy.  Iron or stainless steel wire may be coated with copper by heating the iron to about 1150 DEG  C. in a hydrogen atmosphere and immersing in a bath consisting of copper or of 99 per cent of copper and 1 per cent nickel.  Stainless steel wire may be coated with silver by the said process by heating the wire to about 1000 DEG  C. in hydrogen and immersing it in a molten bath consisting of 99 per cent of silver and 1 per cent of a copper phosphorus alloy.  In each case the stated base metal temperatures are maintained during coating and after the base metal has left the coating bath.

Title: Improvements in or relating to indicating devices
IPC: H01C10/14
Filed: 1953-05-27
Abstract: 734,235. Counting-apparatus; indicating- apparatus. BECKMAN INSTRUMENTS, Inc. May 27, 1953 [March 9, 1953], No. 14751/53. Classes 106 (1) and 106 (4). [Also in Groups XXXVI and XL (c)] A device for indicating the angular position of a rotor comprises a first rotatable indicator connected to the rotor, intermittently operating gear means connecting a second rotatable indicator to the first indicator once per revolution of the latter, and locking means for securing the first indicator and rotor in any desired angular position. As shown, the extent to which a shaft 22, Fig. 1, is rotated, is indicated by a fractional turn or first indicator 67, Fig. 2, mounted rigidly on the shaft 22, and by a coaxial second indicator 38 brought into geared relationship with the first indicator 67 once during each revolution of the latter. The second indicator 38, Fig. 3, has inwardlydirected gear-teeth 43 bearing against two axially-extending annular projections 61 forming a hub about which the second indicator 38 rotates. The annular projections 61 are formed on abase 37. The gear teeth 43 are continually in mesh with a gear-wheel 44 rotatable on a pivot 66 extending from the base-plate 37. The first indicator 67 has a small inwardly directed gear segment 42, Fig. 4, adapted to mesh with the gear-wheel 44, to drive the second indicator 38, once during each revolution of the first indicator 67. To prevent rotation of the second indicator 38 when the gear-wheel 44 is not in mesh with the gear segment 42, alternate teeth on the gear-wheel 44 are made axiaily longer than the teeth there-between, as best shown in Fig. 1. When the gear segment 42 is out of mesh with the gear-wheel 44, two of the elongated teeth 76 on the gear-wheel 44 engage an annular shoulder 77 directed radially inwards on the first indicator 67, thus preventing rotation of the gear-wheel 44 and the second indicator 38. Locking of whole apparatus. A brake shoe 45 is pivoted on a pin 83 on the base-plate 37 and rests against a hub portion 81 of the first indicator 67. The rear face of the brake shoe 45 is so shaped that by appropriately deflecting a finger-piece 89, a cam tab 86 can be wedged between the brake shoe 45 and one of the annular projections 61 to cause the brake shoe 45 to hold the shaft 22 in the position to which it has been set. Variable resistor. The device in Fig. 1 is associated with a variable resistor comprising major turns 14 each wound with a large number of minor turns 14a. The shaft 22 carries a collar 24 keyed to but slidable along the shaft, the collar carrying a contact arm 28 grooved at its end to partly encircle the resistance element 14. As the shaft 22 is rotated, the contact 28 will follow the turns of the resistance element 14. The device is used to indicate the amount of resistance permitted to become effective on rotating the shaft 22.
