Title: Electrical connector
IPC: H01R13/22
Filed: 1978-08-03
Abstract: An electrical connector assembly, for making connection with an LCD panel 11, comprises contacts 25 each formed as a pip in a conductor strip 26, moulded in a resilient elastomeric insulator 24. In its upper face the insulator has an aperture 28, closely surrounded by an annular upstanding sealing lip 29. The insulator 24 is received in a rigid base 14, having a support pip 34 underlying each contact 25. When the LCD is pressed towards the base 14 (by clamping means not shown), lip 29 is compressed to provide a seal around the electrical contact area, and the contact is resiliently urged against the LCD by the portion of elastomeric insulator between the contact 25 and the rigid pip 34. <IMAGE>

Title: Digital control of a thyristor circuit
IPC: H02M3/139
Filed: 1978-08-09
Abstract: The thyristor circuit comprises main, dropping, recharging and additional thyristors 25-28, and operates in two stages to apply chopped d.c. to load 31 e.g. a motor. In the first stage the digital control applies a regular train of pulses to thyristor 26, a second pulse train, progressively delayed with respect to the first, to thyristor 28 and a pulse train with fixed delay relative to the second to thyristor 27. In the second stage, a regular train of pulses is applied both to thyristors 25 and 27 and a progressively delayed pulse train is applied to thyristor 26. The trains of pulses are generated in the two stages by AND gates 14-17 and delay circuit 23 under control of clock 1, counter 2, decoder 3, bidirectional counter 4 and control unit 5, with switching from one stage to the other effected by decoder outputs 7, 8 through AND gates 18-20, NOT gate 21 and flip-flop 22. <IMAGE>

Title: Apparatus for folding carton flaps
IPC: B65B7/20
Filed: 1978-11-06
Abstract: In an apparatus for closing at least one end of a carton by folding in pairs of inner and outer closure flaps 19, 20, 12 and 13, the outer closure flaps 12 and 13 are prevented from overlapping one another by a separator 17 which projects between the flaps 12, 13 during folding. The inner flaps 19 and 20 are folded by pivoted and stationary folders (23, 22) Figure 2 (not shown) as the cartons 10 travel on a pocketed conveyor belt (25), Figure 1 (not shown), then the outer flaps 12 and 13 are folded by conventional folders (not shown). In the illustrated apparatus both ends of each carton are closed and two separators are provided, each separator 17 comprising an elongate spring steel blade which is held in a rigid bar support 18 and projects to retain the inner flaps 19 and 20 in their folded positions and guide and separate the edges 15 and 16 of the outer flaps 12 and 13 so that the latter cannot overlap. <IMAGE>

IPC: G01N29/265
Filed: 1978-11-21
Abstract: A carriage 10 includes a guide member 28 which cooperates with a tracking ring 7 on a pipe member. The carriage carries, for example, an ultrasonic, multi-transducer probe assembly 80 for the non-destructive testing of welds 8. On movement of the carriage around the pipe member, the guide member and tracking ring cooperate to ensure the maintenance of a constant geometrical relationship between the probe assembly and the weld to be tested. The carriage is driven around the pipe member by a chain 34 and sprocket wheels 32. The carriage may be modified to carry a welding torch (Figure 15, not shown). <IMAGE>

Title: Anti-skid braking systems of motor vehicles
IPC: B60T8/1764
Filed: 1979-03-16
Abstract: An anti-skid system has associated with each individual wheel of an axle a sensor for determining the rotational behaviour of the wheel, and evaluating circuit responsive to signals from the sensor for producing brake pressure control signals, and a brake pressure control device for separately varying the brake pressure in dependence on the rotational behaviour of the wheel. Each channel, comprising the evaluating circuit and the brake pressure control device associated with an individual wheel, includes means for reducing the gradient of the brake pressure increase of that wheel under predetermined conditions and is coupled to the channel associated with the other individual wheel on that axle such that when a tendency to lock occurs at one wheel, the gradient of the pressure increase is reduced at the other wheel. The amount by which the gradient is reduced depends on the speed of the vehicle.

Title: A drilling and chiselling hammer
IPC: F02B75/02
Filed: 1979-06-28
Abstract: The invention aims to improve the power/weight ratio of a two-stroke engine employed as the prime mover in a drilling and chiselling hammer 1 (sometimes also known as a percussion tool) of the kind in which percussion impacts are transmitted to a tool holder 3 of the tool by way of a percussion piston 9 which is reciprocated by the engine, thereby to enable the tool to be lighter, so that it can more readily be manipulated in the case of a hand-held tool. To achieve this improved efficiency, crank 7 of the percussion piston 9 is accommodated in a chamber 1a into which air is drawn by way of a non- return valve 11 upon movement of the piston 9 towards the top dead-centre position and from which air is displaced, under compression, through a pipeline 13 to an entry slot 1e of the cylinder 1c of the engine. <IMAGE>

Title: Electrical, Multicore Flexible Sheathed Cable
IPC: H01B13/02
Filed: 1979-07-09
Abstract: In order, in flexible sheathed cables, to save a stranding step, the individual wires (10) of conductors (20) intended to be stranded together are guided parallel to each other into an extruder (16) which applies an insulating sheath to the wires so as to form a sheathed conductor. Stranding of the sheathed conductors then takes place to form the cable, and retroactively (or by feedback) during the stranding of the conductors (20), stranding of the wires in each conductor is effected without twisting-back and at a greater lay length than that of the stranded conductors. <IMAGE>

Title: Track brake for rail vehicles
IPC: B61K7/02
Filed: 1979-09-06
Abstract: A plurality of brake bars (1a, 1b) of elastomeric material or rubber are arranged end-to-end in a row so that adjacent ends of neighbouring bars abut and the upper surface of each end portion (2) of each bar (1a, 1b) has a chamfer (3) so that each end portion (2) slopes downwardly towards the adjacent end of its neighbouring bar. When a rail vehicle passes over the track brake the chamfered end portions (2) are subjected to less deformation, and thus fewer potentially damaging edge stresses, than a non chamfered end portion. The chamfer (3) preferably has a length (4) to height (5) ratio of approximately 3.5:1. <IMAGE>

Title: Multi-colour print ribbon
IPC: B41M5/10
Filed: 1979-09-27
Abstract: A colour print ribbon for multi- colour printing has transferable ink coatings in three colours, magenta, cyan and green. In addition to printing directly in these three colours, printing is possible in four more colours by over-printing with pairs of colours and with all three colours. It has been found, however, that for all seven colours to have an acceptable contrast with respect to a white print-receiving medium, and for all colours to be clearly distinguishable one from the other, the green should be selected from a specific range of green colours. The selected range is shown on a chromaticity diagram based on standard Source C as lying between a boundary 5 corresponding to a dominant wavelength of 515 m mu  and a boundary 4 corresponding to a straight line passing through coordinates (x4 = 0.40, y4 = 0.55) and (x5 = 0.30, y5 = 0.40). A green ink having a colour substantially in the middle of the selected range can be made by mixing one part of process cyan ink with two parts process yellow ink. <IMAGE>

IPC: F15B11/076
Filed: 1979-12-03
Abstract: A compressed air or hydraulically operated cylinder (10-14) has an attached damping device which operates at the ends of the piston's stroke to brake the latter together with the piston rod 14 in a jerk-free manner and more positively than hitherto even with large masses and at high speed. The damping device consists of a sleeve (24) slidingly arranged on the piston rod for displacement by abutment discs (20, 22) thereon and provided with a piston (25) which is tightly slidingly guided in a damping chamber (26). The two sides of the damping chamber are connected to one another by a duct (43) and bores (37, 38) the cross-sectional area of which can be varied to a greater or lesser extent by means of throttle bolts (39, 40). During damping of the leftward stroke fluid flows from the left side of the chamber (26) to the right side through an annular space (51) between the sleeve (24), and the throttled bore (38), the duct (43), a chamber (30) and bores (29) controlled by non-return valves (33). <IMAGE>
