Abstract: 1,087,048. Livestock feeding appliances. FEED SERVICE CORPORATION. Aug. 5, 1966 [April 6, 1966], No. 35262/66. Heading A1M. Apparatus for distributing liquid feed to animals comprises a feed supply tank 10 to the outlet 15 of which is connected a tubular member 18 arranged to swing downwardly in a vertical plane from an upper position corresponding to an upper level of liquid in the container to a lower position, movement of the member 18 being under timed restraint, and feeder means 30 accessible to feeding animals and connected with the upper outlet end of member 18. Downward movement of member 18 is controlled by a clock-work motor 31 arranged to rotate a reel 38 on which is wound a cable 40 connected to the outlet end of member 18 the descent speed of which is determined by reduction gearing in box 35. Liquid feed flows to the feeder means 30 from member 18 via pipes 21, 29, the supply being cut off if the feed level in container 10 falls below the upper outlet end of member 18 and resumed when the outlet end falls below the liquid level in container 10 under the control of motor 31. The feeder means 30 may be as described in Specification 1,087,047 and comprises a ball adapted to project through an opening in a hollow member and accessible for licking by an animal. The apparatus may be permanently fixed in its position of use or be mounted on skids, as shown, or on wheels. Reels 38 of different diameter may be provided to vary the descent speed of member 18 and pipe 21 may be rigid or flexible. A flexible conduit 43 connects the outlet end of member 18 with the interior of container 10 above the maximum level of feed therein.

Title: Anti-locking systems for vehicle brakes
IPC: B60T8/34
Filed: 1973-07-26
Abstract: 1440457 Anti-skid circuits SOC ANON AUTOMOBILES CITROEN 26 July 1973 [31 July 1972] 35547/73 Heading F2F In an anti-skid wheel braking system, a wheel brake element is selectively coupled by a wheel rotation sensor-controlled valve 2 to a pressure fluid source or to a reservoir 6 via a pipe 5 having a flow restriction 50, wherein a displaceable member 39 controls a variable volume between the valve 2 and the restriction 50 and has a shutter element coupled thereto which controls flow through a second pipe 100 bypassing the restriction, allowing such flow when the volume is a maximum value, this second pipe having a shut-off element 103, controlled by pressure in the pipe 5 between the valve 2 and the restriction, which prohibits flow therethrough when this pressure exceeds a predetermined value. When a pressure release signal from the detector is received by the valve 2, the brake is communicated with the pipe 5, moving the displaceable member 39 to allow fluid flow into pipe 100. If the back pressure in the valve 2 is higher than the force of a spring 106, during high adhesion conditions of braking, flow to the reservoir via the pipe 100 is blocked, so that pressure decrease is gradual (through the restriction 50). However, during braking under low adhesion conditions, the back pressure is less than the spring force, allowing full flow through the pipe 100 and rapid pressure decrease for brake release. If, during high adhesion conditions, the wheel does not reaccelerate rapidly enough, the back pressure drops to the spring rate allowing flow through the pipe 100 and a final rapid pressure decrease. Reference has been directed by the Comptroller to Specification 1,319,108.

An impurity element is applied to the surface of a semi-conductor and at the regions where a non-rectifying connection is to be made a second impurity element is applied which is able to destroy the ability of the first impurity to form a rectifying junction. The latter junction may or may not already have been made in other regions of the body. A rectangular slice of germanium 1 is coated with indium on each side 2, 3, a separate portion 4 being marked off by removal of some of the metal. Further indium is deposited on 2 and 3, while layer 4 receives tin or an indium-tin alloy, after which the plate is fired to diffuse the metals into the germanium.
