Title: Improvements in or relating to valve apparatus for rock drills and like fluid pressure operated tools
IPC: B25D9/18
Filed: 1924-11-28
Abstract: 234,001. Rayner, G. H. T. Nov. 28, 1924. Fluid-actuated valve gears.-An improvement in the gear described in Specification 133,642 consists in dispensing with the central passages connecting the faces 7 with the central annular recesses in the valve and substituting therefor passages 4, 14 in the valve-chest closure members connected to the cylinder passages c, d. In the position shown, the valve is locked by fluid passing to the left-hand end of the valve chamber through ports 8 ; the piston is moving to the left; and the left and right hand auxiliary chambers in the valve are in communication with the outlet and supply respectively. When the piston passes port k, fluid passes to the right hand, annular end of the valve-chest and the valve is reversed; fluid passing indirectly to the left-hand auxiliary chamber through passages 14, 4 rather than directly as in the prior Specification thereby avoiding a partial cushioning of the valve during its reversal and permitting increased speed.

Title: Preparation of piperazine
IPC: C07D295/023
Filed: 1957-09-11
Abstract: Hydrogenation catalysts for the conversion of ethanolamines to piperazine comprise nickel, cobalt or copper or their oxides or mixtures thereof.  They may contain a minor proportion of chromium oxide, molybdenum oxide, manganese oxide or thorium oxide as promoter.  The catalyst may be carried on an inert support such as silica, Filtros and alumina.  When oxides are used they may be pre-reduced by heating to 200-400 DEG  C. in a stream of hydrogen. Specified catalysts are one containing 75% NiO, 22% CuO and 3% Cr2O3, and the corresponding catalyst obtained by reduction with hydrogen to form metallic nickel and copper and chromium oxide.  Further catalysts used in examples are reduced nickel chromite, reduced nickel-copper-manganese oxide, and reduced copper chromite containing 84% CuO and 15% Cr2O3.ALSO:Piperazine is prepared by reacting a mono-, di- or triethanolamine, or mixtures thereof, with ammonia, the mol. ratio of ammonia to ethanolamine being at least 2 : 1, in the presence of hydrogen and a hydrogenation catalyst comprising nickel, cobalt, or copper or their oxides or mixtures thereof, at 150-400 DEG C. and 30-400 atmospheres.  Water may also be present. The partial pressure of the hydrogen is preferably at least 10 atmospheres.  The hydrogenation catalyst may also contain a minor proportion of chromium oxide, molybdenum oxide, manganese oxide p  or thorium oxide as a promoter.  In place of the ethanolamine reactant, a mixture of ethylene oxide with a molar excess of ammonia may be used. Ethylenediamine is obtained as by-product.

Title: Improvements in electronic gating circuits
Inventor: DELANOY DONALD BRIAN
IPC: H03K17/54
Filed: 1959-08-26
Abstract: 942,922. Valve gating circuits. PYE Ltd. Aug. 26, 1960 [Aug. 26, 1959], No. 29216/59. Heading H3P. A gating circuit comprises two gating devices, to which separate input signals are respectively applied, having a common output circuit, the arrangement being such that the application of two control signals to the circuit causes one of the gating devices to conduct, and the absence of one of the control signals causes the other of the gating devices to conduct. The signals F1, F2 to be gated are fed to the control grids of pentodes V1, V2 which are normally biased to be non-conducting. Application of positive pulses to terminals B, C simultaneously causes V1 to conduct and connected input F1 to the output circuit, V2 being held cut-off by the low potential on its suppressor due to the transistor T being cut-off by the pulse at C. Application of positive pulses to terminal B alone causes V2 to conduct, connecting F2 to the output circuit, the transistor T now being conducting, whilst V1 remains cut-off due to the low potential at C. Application of pulses simultaneously to terminals B and D causes both valves to conduct. The rise in potential at the suppression is limited by clamp diodes D1, D2 connected to a potential defined by Zener diode D3. Other electronic gating devices such as triodes or diodes may be used in plac eof pentodes V1, V2. Specifications 942,921 and 942,923 are referred to.

Tape 1 from a roll 32 passes through a block, 3a, 3b and passes beneath a row of punches 7 spring biased away from the tape. The tape passes a reader containing a light source 27, optical guides 28, further optical guides 29 and a set of photo electric detectors 30, is driven by a sprocketed roller 4 and is taken up on roll 33. The punches 7 are operated by an eccentric cylinder 10 via spring loaded arms 12 pivotally mounted on arms 14 pivoted about an axis 15, there being a set of arms for each punch. Each arm 14 has a portion 14b raised by the eccentric to contact a respective electromagnet 18. If the punch is to be operated the electromagnet is energized and a thickened portion of arm 126 is inserted between the eccentric and the punch so that the eccentric lowers the punch. If the punch is not to be operated the electromagnet is not energized and the thinner tip of the arm remains between the punch and the eccentric. The drive shaft for the eccentric carries two discs each having a slot passing light from a source to a respective photo electric element. If the timing between pulses from each source is above a predetermined value a circuit containing a monostable and AND and OR gates is operated to prevent operation of the punch since the machine will be running at the wrong speed (Fig. 6, not shown).

Title: Liquid dosing apparatus

Abstract: 604,479. Fluid-actuated valves. RUSH, H. A. Nov. 7, 1945, No. 29633. Convention date, Dec. 8, 1944. [Class 135] [Also in Group II] Means for treating water with a liquid chemical comprises a faucet having a swinging spout 5, Fig. 1, which in one position delivers untreated water and, in another position, a mixture of chemical and water in predetermined proportions. The spout 5 is rotatable about a tubular member 6, Fig. 2, clamped against the outlet nozzle 8 of a manifold 1 having inlet valves 2, 3 for hot and cold water. Chemical is delivered from a tank 32 through a device 31, which maintains a constant pressure head, and a flexible hose 30 to an inspection chamber 21. When the spout 5 is swung into position for delivering treated water, a valve plate 44, rotatably secured by a stud 45 to a member 36b, rigid with the spout 5, is held against rotation by the engagement of a lug 44b depending therefrom with a slot in the tubular member 6. A channel 43 in the member 36b is thereby brought in alignment with an arcuate slot 44a in the valve plate 44, and when water under pressure is passed from the manifold through a passage 5a in the spout 5, part of the flow is diverted through the slot 44a and channel 43 into a chamber 18 from which it is released through an exhaust outlet 39. A metallic bellows 35 in the chamber is actuated by the water pressure to open a valve 24 against the pressure of a spring 27, and liquid chemical is released from the chamber 21 into the compartment 18, whence it is drawn through a passage 5b by the water discharging from the passage 5a. In the other position of the spout 5 the passage 43 is closed by the valve plate 44 and water only passes through the spout 5 via the passage 5a.
