Title: Distributor device for cow teat disinfectant - cap on end of passage forms outlet for disinfectant in squeezable container
Inventor: ZACKHEIM ELI A
IPC: A61D7/00
Filed: 1975-04-15
Abstract: The device is particularly for washing the teats of dairy cows to prevent mastitis, and fits on a flexible vessel which has a large mouth and contains liquid. An annular top wall extends round the socket and has a skirt extending from it for attachment to the vessel. The socket has a continuous sidewall inclined towards the inside, also a base, and there is a single passage running through the socket wall from the inside of the vessel. A cap fits over the end of this passage in the socket so as to leave a space between it and the passage end, so that liquid can be forced into the socket from the vessel by squeezing the latter.

Title: Ground fault circuit interrupter - has differential current sensor with short circuiting electronic switch
Inventor: HOWELL EDWARD KEITH
IPC: H02H3/33
Filed: 1976-04-28
Abstract: The secondary winding of a differential current transformer in a ground fault circuit interrupter is short circuited through an electronic switch. The switch is periodically opened to force any secondary current occasioned by the existence of a ground fault to flow through a load resistor, thereby developing a relatively high amplitude signal voltage, there across for processing by a signal processor, after the initiation of the circuit interruption. The differential transformer forms the system current sensor.

Title: Laboratory respirator for small animals - has breathing rate regulated by two three-way solenoid valves controlled by thyristor
Inventor: LAMBERT ALAIN
IPC: A61M16/00
Filed: 1976-05-26
Abstract: The respirator regulates the breathing rate of small animals used for laboratory purposes. It comprises two three-way solenoid valves which are controlled by a thyristor, its trigger being operated by rectangular wave signals from an abstable multivibrator. The gas pressure from the storage bottle is reduced before entering the first solenoid valve. During inhalation, the gas passes straight through both valves, an orifice plate providing second stage pressure reduction. During exhalation, both valves switch to atmosphere, the first disconnects the supply from the bottle and depressurises the connecting line between the valves, the second exhausts the spent gas.

Title: Air motor for pneumatic drill - has intermediate chamber under air pressure to seal cooling water inlet chambers
IPC: F03C1/20
Filed: 1976-11-10
Abstract: The motor has a body with an internal cylinder and a sleeve within which the driving piston reciprocates. The sleeve within which the driving piston reciprocates. The sleeve is shaped to provide chambers at the ends of the piston and an intermediate chamber between them. Cooling water is admitted to the end chambers and can flow through longitudinal passages through the piston into a central passage in the bit. It escapes from the end of this to cool the working face and remove chips. Air is admitted to the intermediate chamber at a pressure higher than that of the cooling water in the end chambers. This prevents leakage of water out of the end chambers past the seal between them and the intermediate chamber.

Title: Hydrostatically operated automatic crane stability system - uses increasing load moment to cause reduction of boom extension
IPC: B66C23/90
Filed: 1976-12-21
Abstract: A crane has a lift jack (A) and a boom which is extended and retracted by a jack (C) along the boom. When lowering a load from (P) to (P') the moment exerted by the load increases, possibly to a dangerous level. The increasing moment is reflected by increased pressure in jack (A) at the base of the boom. This is fed to an automatic cut-out valve which, on operation, causes a pump to stop closure of jack (A) and admits fluid into jack (C) in a closing direction. When pressure in jack (A) reduces to a safe level again the cut-out reverts enabling jack (A) to continue closing so the load lowers at the reduced extension of the boom.

The screw is pushed through a resilient nose cap, exposed for positioning on the workpiece. Axial movement is adjustable. The tool adapts to portable handling or machine mounting. A feeder (4) delivered screw (3) lies aligned in the nose (2) cap (13). The nose moves axially, relative to the driving blade (9) and a shank with a pneumatic cylinder slides through a set of guides. The nose is lifted to push the screw thread outside the nose. A piston rod nut sets the stroke.

Title: Automatic type propeller shaft brake - has spring operated fit shaft disc applied and released when engine stops and starts
IPC: B63H23/32
Filed: 1977-03-23
Abstract: There is a ram (9) the piston (15) of which is controlled by a spring (14) which presses on a disc (1) via two small plates (18). These plates are practically non-wearing and the disc (1) is fixed on the propeller shaft. Due to the non-wearing properties of the plates (18) the piston travel is almost constant for life, so avoiding the usual brake adjustment troubles normally met. The brake can be used on almost any type of vessel having an inboard engine, whether the propeller shaft is running or not. The arrangement avoids shock inseperable from dog type locking devices.

A transverse hole (19) enables the bar to be tightened with a suitable tool. A second piece of tube (2) is fitted over the bar (8) and retained by a screw (17) which engages a circumferential groove (16). If required the block (7) may have a second tapped hole at right angles to the hole (14) so that a third tube may be assembled in a similar manner.

Title: Hydroxyethyl-ethylene-di:amine-tri:acetic acid - used to prevent aluminium being corroded by etching solns. for semiconductor devices
Inventor: DUBOIS GUY
IPC: H01L21/311
Filed: 1977-06-06
Abstract: An etching soln. for baring external contacts on semiconductor devices contains chemicals to attach the protective coating on the aluminium metal bases, along with a complexing agent to prevent any corrosion of the Al metals during the etching process. The etching soln. may be used in compsns. for use with isolated bipolar semiconductors with field effect as well as integrated circuits, notably MOS types. Corrosion is considerably reduced thus stopping discolouration and cratering of the aluminium even in the most unfavourable circumstances. Specifically even after 5 mins. immersion in etching soln. contg. complexant the total thickness of aluminium stripped off is only 500 angstroms. Aluminium attack is this almost totally inhibited.
