Title: Improvements in or relating to electric power distribution systems
Inventor: SEPHTON ALBERT
IPC: H02G5/00
Filed: 1959-09-11
Abstract: 894,781. Distribution boxes. BRITISH INSULATED CALLENDER'S CABLES Ltd. Sept. 12, 1960 [Sept. 11, 1959], No. 31120/59. Class 38 (1). A distribution system for machine shops and the like comprises a number of busbars having a continuous sheath of insulation, and each bus - bar held in mutually-spaced relationship are supported at intervals along their length by attachment to a longitudinally-extending support by means of a plurality of two-part clamps common to all the bus-bars of the system, one part of the clamp forming part of or carrying a connecting-box. The system shown consists of a number of solid or tubular copper rods 2, each continuously sheathed by insulation 3 and having equidistantly spaced tapped holes 4 along its length for the purpose of making electrical connections. The holes 4 of the several bus-bars are arranged to be in transverse alignment with one another. Where electrical connection to the system is required, the screw-threaded ends of a number of metal pins 30, one for each bus-bar, are screwed into the selected tapping place. The free ends of the pins pass through holes in the lower part 20 of a transverse two-part clamp 19-20 of insulation material used for holding the bus-bars in a mutually spaced relationship to one another, the bottom part 20 of the two part clamp having dependent from it one vertical wall of a connecting-box 16. Each lead from the apparatus or machine to be supplied from the system is either connected directly to the appropriate pin 30 or to the lower terminal 36 of a fusible cut-out 32 attached to the pin 30 by means of the upper terminal socket 34. Channel-section members 40 secured to the dependent vertical wall, by screws 41, form the other three sides of the connecting-box 16. The transverse two-part clamps 19-20 are used to attach the bus-bar system to longitudinal supports 8, either made from highly-conducting metal of angle-, T- or channel-section, or one which has its conductivity augmented by means of a highly conductive longitudinally running tape 26. An earth lead from the consuming point is connected to the longitudinal support 8 directly, or to the conductive tape 26. Where no electrical connection to the bus-bar is required, the tapped holes 4 may be covered by means of a screwed plug 17 of insulating material, or by covering them by a garter or winding of insulation material.

Title: Improvements in or relating to suspension means for road vehicles
IPC: B60G15/06
Filed: 1935-11-12
Abstract: 452,895. Vehicle spring-suspensions. HOOPER, L. R., 194, Kitchener Avenue, Kensington, Johannesburg, South Africa. Nov. 12, 1935, No. 31279. [Class 108 (ii)] In a road vehicle suspension the weight of the chassis and superstructure is transmitted to an axle or like wheel-carrying member by hydraulic load and shock-equalizing means or distortion-preventing means comprising intercommunicating hydraulic cylinders, the pistons or the like of which are connected to the axle. As shown in Fig. 1 pistons or plungers 25 secured by the bifurcated ends of rods 26 to the axle 2 are slidable in cylinders 3, 4, which are connected hydraulically through flexible tubes 9, 10, pipes 5, 6, and a valved T-piece 8, and are pivotally connected by bifurcated links 19, 20 to the main spring 1. In operation, movement of either wheel relatively to the other displaces liquid from one cylinder to the other and equalizes the load on the wheels. Movement of either piston towards the bottom of its cylinder is retarded by a hollow, flanged, piston - extension 30 entering an air or liquid-filled recess 37 formed between the cylinder and a boss 32. In another construction, Fig. 3, the main spring 1 is dispensed with the cylinders being connected at their lower ends bv the links 19 to a rigid member 42 of the vehicle frame while the upper ends of the cylinders communicate with a cushioning cylinder 43 containing spring- separated pistons 44, 45 connected by rods 48, 49 slidably connected by a sleeve 50. A shock on either wheel causes the pistons 44, 45 and intervening spring arrangement to move bodily in the cylinder 43 to equalize the liquid pressure in the cylinders 3, 4, while a shock on both wheels simultaneously causes the pistons 44, 45 to approach each other, the shock being cushioned by the spring 56. The opposite ends of the cylinder 43 communicate through a pipe 65 by means of which the pistons 44, 45 are centred in the cylinder. In a modification, the cylinder 43 &c. is replaced by one or more cylinders each containing a single spring-pressed piston. The invention may be applied to the front or rear wheels or to all four wheels.

Abstract: 1,271,796. Stacking machine for planks and the like. TIMBER RESEARCH & DEVELOPMENT ASSOCIATION. 10 Sept. 1969 [1 July, 1968], No. 31288/68. Heading B8C. In a machine for automatically stacking planks and the like planks 11, received from a planer or moulder, not shown, on to an inclined shelf 14, are guided into alignment by a bracket 13 as they slide sideways over a shallow shoulder 12 and drop, into a waiting position, between vertical walls 16, 17 and on to a bottom shelf 15 where a detector 18 initiates the movement of a pusher 19 to transfer the lowermost plank sideways above a stacking position, one end of the plank dropping on to a shoulder 21 and the other end falling to the bottom of the stacking position or, on to planks already stacked. The operation of the detector 18 also causes a pusher 24 to move slowly, at least at the end of its stroke, along the shoulder 21 to push off the adjacent plank end so that it drops, substantially vertically, below the edge of the shoulder 21 which acts as a fair-ending device. Withdrawal of the pusher 24 moves forward a height detector 25 which is vertically adjustable and acts as a counter, and which also actuates a sideways thruster 26 when it detects a plank present at the desired height of the stack, the thruster 26 moving the latter, and any other previously completed stacks, laterally for eventual removal by a lift fork. The detector 18 is rendered inoperable while the thruster 26 is in operation so that planks from the planer can be stacked in the waiting position 15, 16, 17.
