Patent GB-1221184-A (GB)
Title: Improvements in current collection installations for vehicles
Inventor: TUSTIN ARNOLD
IPC: B60L5/22
Filed: 1967-11-03
Abstract: 1,221,184. Current collection installations for vehicles. BRITISH RAILWAYS BOARD. 31 Jan., 1969 [3 Nov., 1967], No. 50132/67. Heading B7L. [Also in Division G3] The contact head 4 of a pantograph installation is maintained in electrical contact with an overhead conductor wire 5 by a servo-system which includes a slug member 8 whose inertia is used to vary the pressure of the fluid acting in a cylinder 2 on a piston 3 which supports the contact head 4 in such a manner that the pressure includes a component which is proportional to the vertical acceleration of the contact head but which is in the opposite sense thereto. In an embodiment, Fig. 1, the slug 8 is connected to the rod 13 of a control valve 10 which controls flow of fluid from a fluid pressure source to the cylinder 2, and a negative feedback of pressure is applied to the rod 13 by a bellows or piston 14 so that the net thrust of the piston is proportional to the force applied to the rod 13 by the slug. A constant force is applied to the valve 10 by a spring and hence the head is urged upwards; alternatively the force may be varied by arranging a tiltable transverse bar to engage the cable and to respond to the zig-zag arrangement of the cable to control the valve 10 so that the upward force on the head 4 is smaller at midspan that at the span ends. In a modification, Fig. 3, the control valve 10 is combined with the piston 3 within the cylinder 2. Pressure fluid flows continuously through holes 6 in the piston 3 and is variably throttled by a slug 8 acted on by a spring 7 above the piston which slug is displaceable from an equilibrium position. To reduce the excess forces which occur when the wire is accelerated towards the vehicle, additional springs are provided to urge the head downwards; alternatively the fluid forces act downwards and springs are provided to give upward force on the head. Damping is provided by a projection on the piston 3 engaging a recess in the slug 8. In another embodiment, the spring 7 acts between the slug 8 and the end of a rod attached to the piston.  The height of the frame may be varied by springs between the head and frame in parallel with the servo-system; alternatively, slowacting fluid pressure operation of the frame may be employed.

Abstract: 1394318 Preparation of silver chloride powder YARDNEY INTERNATIONAL CORP 29 Oct 1973 [7 Dec 1972] 50146/73 Heading C1A Silver chloride is prepared by heating metallic silver to above the melting point of silver chloride but below the melting point of silver in a reaction zone, introducing chlorine gas above the heated silver and withdrawing the resulting molten silver chloride from the reaction zone below the heated silver, heating the withdrawn silver chloride to at least 1100 F. but below the decomposition point thereof and then passing this heated silver chloride in finely dispersed liquid form into water, recovering the resulting brittle silver chloride flakes and disintegrating these flakes to granular form. The process can be carried out batchwise or continuously and results in particulate silver chloride of high purity with decreased energy expenditure. Granulation is usually carried out on the dried silver chloride flakes.

The curved arms 6 are opened and closed during reciprocation by cams so that the traveller is entrained by the arms during the return stroke as they describe semicircular paths sweeping around the ring from a common starting point to a predetermined position in which the traveller is finally located. As described, when a yarn break is detected, piston 17 moves the group forward so that a roller runs up cam 16 to raise the group, along cam 15 towards the ring and then allow the group to descend to bring brushes 8 mounted at the end of arms 6 into contact with the far side of the ring. The group is then returned and the brushes move around the circumference of the ring dragging the traveller 5 to the front position of the ring.

Abstract: 1,139,421. Raising steam in forced flow once through steam generators. FOSTER WHEELER Ltd. 16 March, 1966 [17 Dec., 1964]. No. 51412/64. Heading F4A. A once-through forced flow steam generator, comprising economizer, evaporator and superheater sections 1, 2, 3 respectively connected in series, is connected to a turbine 11. The exhaust from the turbine passes to a condenser 13 from whence feed water is drawn through a de-aerater 19, by a feed pump 5 and delivered through a high pressure feed water heater 20 to the generator. During start-up and low load operation, between 30 and 60% of the flow through the evaporator surface 2 is recycled back through line 10a and mixed with cooler inlet water by pump 14, to prevent the evapo rator tubes from over-heating, the remainder of the flow passing to a steam separator 16. The water from the steam separator passes to the condenser, whilst part of the steam passes through the superheater 3 and is used to roll and warm the turbine, the remainder being either used in the de-aerater 19, the high pressure feed water heater 20, the turbine seals 24, or passed to the condenser 13 through a desuperheater 22. In a modification (Fig. 2) a two part superheater is utilized and throttling valves (23) are incorporated between the evaporator surface and the first part of the superheater, whereby the former may be brought up to full operating pressure whilst the turbine may be supplied with low pressure high enthalpy steam according to its requirements during start-up.

A levelling system for a vehicle headlamp includes a headlamp (11) mounted about a horizontal axis (12) means for pivoting the lamp according to the attitude of the vehicle body relative to the road and locking means (24) sensitive to the attitude of the ground occupied by the vehicle to prevent adjustment of the headlamp except while the vehicle is on horizontal ground. Lever 13 pivots about 14 to adjust the attitude of the headlamp 11 according to whether the vehicle is loaded at its rear or front. Lever 17 is mounted on a brake drum of the vehicle and when the vehicle is on other than horizontal ground then one of the two pairs of contacts 19, 22 or 21, 23 will be closed and thus energize electromagnetic brake 24 which will prevent weight 15 and lever 13 moving to bring the headlamp 11 back to the horizontal. Dampers 26, 27 are provided to prevent the levers being moved by irregularities in the ground. The system may be modified by arranging that headlamp 11 replaces the lever 13. Further the lever 17 need not be mounted on a brake drum but on some other part of the vehicle which is not moved angularly during loading of the vehicle.
