Title: Headlamp adjusting systems
Inventor: BAKER ALFRED DICKENS
IPC: B60Q1/10
Filed: 1968-02-09
Abstract: 1,245,771. Vehicle headlamp adjustment. JOSEPH LUCAS (INDUSTRIES) Ltd. 29 Jan., 1969 [9 Feb., 1968], No. 6460/68. Heading F4R. A road vehicle headlamp adjusting system comprises a member 25 adjusting the headlamp 20 under the influence of piston 22 acting in a cylinder 21 according to the pressure of hydraulic fluid in that cylinder, the fluid pressure being controlled by a further piston 14, in a sensing unit, secured to a rear suspension member of the vehicle and sliding in a cylinder 13. Cylinder 13 and cylinder 21 are interconnected by a pipe 17 via a solenoid operated valve 18. When the vehicle ignition is off, the solenoid causes valve 18 to be open and any fluid displaced from or drawn into cylinder 13 due to the rear of the vehicle body moving relative to the wheels, as during loading or unloading, causes movement of piston 22, member 25 and thus of the headlamp. Spring loaded plunger 26 keeps member 25 in contact with piston 22. To prevent adjustment of the lamps due to normal vehicle suspension movements during travelling, the solenoid operates when the vehicle ignition is on to close valve 18 and isolate the cylinders. Changes in hydraulic fluid pressure in cylinder 13 are then taken up by an auxiliary cylinder 15 in which a spring loaded piston 23 operates. In a modification of this embodiment the plunger 26 may be replaced by a further piston similar to piston 22 but connected to a second sensing unit connected to the front vehicle suspension member. In this modification the two pistons operating the lamp may be interconnected when one of the control valves will not be required. In a further embodiment, Fig. 2, not shown, diaphragms are used instead of pistons to apply and respond to pressure changes in the hydraulic fluid. The place of valve 18 is taken by a device having a diaphragm operated according to the engine manifold pressure to squeeze the flexible pipe in which the hydraulic fluid flows and cut the flow when the engine is running and the manifold pressure is low, but to release it when the engine is stopped and the pressure is atmospheric. A bleeder valve operated by a solenoid controlled by switches on the vehicle doors ensures that the pipe is released when those doors are open for loading or unloading. As in the first embodiment, if a sensing unit is connected to the front as well as the back suspension member, no device for stopping the hydraulic fluid flow is required.

Title: Improvements in circular knitting machines and method of operating same
IPC: D04B15/58
Filed: 1940-04-11
Abstract: 534,645. Knitting-machines. SCOTT & WILLIAMS, Inc. April 11, 1940, No. 6562. Convention date, April 19, 1939. [Class 74 (ii)] Relates to a circular machine for knitting two or more stocking blanks &c., simultaneously, by means of two cam sets rotating about the needle cylinder at different levels and in opposite directions. The invention is applied to the machine described in Specification 484,454 and consists in each feeder taking a yarn, presenting it to a section of needles and then releasing the yarn to be taken by the other feeder. The feeders have open ended terminal guides (Figs. 9 and 10) and are rotatable to cause them to drop or pick up their yarns. The invention permits both cams and feeders to rotate, leaving no part of the machine to oscillate. Fig. 4, is a vertical view, in section, showing the feeders about to pass one another, the dotted lines showing the positions at the moment of passing. The feeder arms 6, 7 are carried by rings 3, 4, rotating in opposite directions. A rotary shaft 73 mounted within lugs of the arm 7 carries a flat spring 74 terminating in a yarn guiding hook 75. The upper feeder is similar, but springs 9, 9<SP>1</SP> coiled opposing ways around shafts 63, 73 tend to twist the shafts in opposite directions. The shafts 63, 73 carry collars 8, 10, having projecting ears 81, 101 which face opposite ways. To release the yarns the ears can be struck twice in each revolution of the feeders by the lower ends of bars 13, 14 carried by normally stationary rings 21, 23. The machine is so adjusted that the feeders pass each other in the blank sections of the cylinder. The spring 64 carries a cam 67 which, projecting in the path of the spring 74, deflects the two springs and allows them to clear each other. Fashioned webs are obtained by racking the rings 21, 23. Two yarns can be fed simultaneously to each bank of needles by mounting two hooks on each feeder arm or by using two separate feeder arms in place of one. The hooks may be placed on the feeder arms at different distances from the needles to enable the hooks to pick up their own yarn. The separation obtained from guide rings 18, 19 is increased by the use of slotted selvedge bits 88 mounted on the cylinder top and projected outwardly as the feeder passes by. The lower slot 90 is shorter than the upper slot 89. The selvedge bit is withdrawn when the feeder coming in the opposite direction has picked up the yarn.

Abstract: 590,674. Protective arrangements. LANDIS & GYR SOC. ANON. March 16, 1945, No. 6732. Convention date, March 27, 1944. [Class 38 (iv)] [Also in Group XXXVI] In apparatus for metering discharge current impulses due to excessive voltages, which may arise from lightning or switching surges, on overhead conductors, comprising a gas-filled vessel closed by a diaphragm for operating an impulse counting mechanism and containing a heating resistor through which passes a portion of the discharge current, means are provided whereby impulses of different energy content are registered on different counting mechanisms, the different mechanisms being selected automatically in accordance with the movement of the diaphragm which is dependent upon the heat developed in the resistor. Means are also preferably provided for metering power arcs following an impulse. As shown, the vessel 1. has a heating resistor 6 and is closed by a diaphragm 2 having a projecting rod 12 connected through adjustable lost motion with a lever 16 which is pivoted at 17 and normally biassed against a stop 19 by a spring 18. The free end of the lever is forked and carries pallets 20, 21 which co-operate with an escapement wheel 22 to permit the counting mechanism I to turn through one unit when the lever is raised by rod 12, the mechanism being powered by a spring drum 46. Impulses of greater energy content are registered on counting mechanism II actuated by a lever 25 through an escapement 29-31, the lever being connected to lever 16 through a lost motion connection 23, 241, 24 so as to be operated only when the heating of the vessel is more than sufficient for lever 16 to be moved through the lost motion distance. Lever 25 is connected through another lost motion coupling 32-34 to a further counting mechanism III which operates only when lever 25 has moved through an angle greater than that necessary to actuate mechanism II. Metering of power arcs is by a counting mechanism IV, the escapement wheel 41 of which is actuated by the armature 43 of an electromagnet 44 shunting the heating resistor. To protect the resistor 6 and electromagnet 44 from excessive current, the resistor in the earthing wire across which they are shunted may be of the non-linear type.
