Abstract: A variable displacement, axial piston pump has workports (10 and 12) and a swashplate (14) controlled by two piston actuators (16, 18) for selecting the displacement, and pumping direction of the pump. Control is effected by way of a control valve (24) with a manually positionable spool (26) and a sleeve (28) connected to a follow-up linkage (30) from the swashplate. The outputs (40, 42) of this valve are connected to the piston actuators (16, 18) by way of an override valve (50) which normally assumes the illustrated position under the action of a bias spring (66). Whichever port ( 10, 12) is the high pressure port is connected by a shuttle valve (36) not only to the control valve (24) but also to a pilot (68) for shifting the override valve (50) to its alternative position in which the workports (10, 12) are connected to the piston acutators (16, 18) to drive the swashplate rapidly back towards neutral, should the pump pressure become too high.

Abstract: A fluid sampling apparatus includes a housing member (1) which contains a lancing needle (16) used for piercing skin together with a spring member (11) for urging the needle to protrude form the housing end sufficient to penetrate the skin. A plunger (14) retracts the needle against the spring tension and a trigger member (2) engages the plunger to hold the needle retracted until released by the trigger. Stop and adjustment tabs (19) limit the depth of needle penetration of the skin and a sample container communicating with the needle receives the sample from the needle. Secondary springs retract the needle from the skin and a suction cam and plunger (22) activated upon retraction of the needle draws the sample of fluid which accumulates on the surface of the skin into the sample container.

Title: A process for dyeing or printing polyacrylonitrile fibres
IPC: D06P3/70
Filed: 1955-01-04
Abstract: Fibres of polymers or copolymers of acrylonitrile are pretreated with a bath containing cuprous ions together with an acid or an acid-reacting metal salt, but substantially no free reducing agent, and then dyed in a separate bath, or printed, with, for example, water-soluble acid or acetate dyestuffs.  The pretreated fibres may be washed before dyeing or printing. Suitable acids and acid-reacting salts are hydrochloric, hydrobromic, phosphorous, oxalic and formic acids and aluminium, antimony, zinc and stannous chlorides.  To provide the cuprous ions a cuprous compound, such as cuprous chloride, may be added to the pretreatment bath or formed in situ by the addition of metallic copper and an oxidizing agent or by the addition of a cupric compound and just sufficient of a reducing agent, e.g. hydroxylamine hydrochloride, formaldehyde sulphoxylate or metallic copper, to effect the reduction.  Basic compounds, such as ethylene diamine, dimethylaniline, mono- or di-ethanolamine and hydroxylamine, neutral salts, such as sodium chloride, and formaldehyde, may also be added to the pretreatment bath.  The process is also suitable for dyeing mixed fabrics of polyacrylonitrile with vegetable, animal or synthetic fibres. Examples are given.  Specification 696,984 is referred to.

Abstract: 303,839. Chauveau, L. L. E. Jan. 10, 1928, [Convention date]. Automatic transmitters.-Relates to an electric signalling apparatus adapted to transmit automatically in Morse code a predetermined signal, such as an S.O.S. signal, and additional signals such as the identification and location of a ship or aeroplane. As shown, the signals are transmitted under the control of a code drum T and code discs IND, SOS, which are driven through gearing by a motor M. The discs IND, SOS are provided with contact segments arranged in codes corresponding to the identification of a ship &c. and a predetermined signal such as a distress call, respectively. The disc SOS may be detachable in order to facilitate replacement by discs bearing different messages. The drum T has on its surface two contact sheets PI, P2, the former of which is shaped so as to form representations of the morse code of the numerals 0- - - 9 in positions corresponding to the brushes 0 - - 9. The plate P2 is similarly formed to represent "South," " West " &c. The brushes 0 - - 9 are connected to horizontal bars N0 - - N9 which co-operate with vertical bars R1 - - R9 through the intermediary of adjustable contacts C on the bars R1 - - R9 which are connected to the contacts of a distributor BA the contact arm of which is moved forward one step by ratchet-and-pawl mechanism for each revolution of the drum T. The arrangement is such that upon starting the apparatus by closing switch INT, the signal predetermined by the disc SOS is repeated three times and then the position of the ship &c. is given in degrees and minutes determined by the setting of the contacts C, one digit being transmitted for each revolution of the drum T. After transmission of the location, the name of the ship' &c. is repeated twice. This cycle is continuously repeated while the switch INT remains closed. Switches M1. M2 are provided for selecting codes corresponding to the nature of the latitude and' longitude. The name of the ship &c. may be transmitted by two code discs switched successively into the transmitting circuit.

Title: Method and apparatus for precipitation of scale-forming materials from solution
Inventor: HOCKINGS WILLIAM A
IPC: B01D3/08
Filed: 1993-07-15
Abstract: Scale-forming metal oxides and carbonates, such as cupric oxide, can be precipitated from an ammonical leaching solution with minimum scale build-up by evaporating the solution in an externally heated rotary drum (16). The rotary drum includes a plurality of axially spaced annular baffles (80) defining a plurality of compartments (84-100) containing a tumbling medium (140), such as spherical balls. The solution (108) is continuously introduced into the inlet end (58) of the rotary drum (16) and heated under pressure to a temperature above its boiling point as it flows over the baffles (80) toward the outlet end (60) of the rotary drum. A slurry containing the precipitated cupric oxide is continuously withdrawn from the outlet end (60). Vapor and gases are continuously withdrawn from the inlet end (58). The balls (140) rub against each other, the interior of the rotary drum (16), and the sides of the baffles (80), as the drum is rotated at a non-centrifuging speed, to provide a grinding or scrubbing action which minimizes a scale build-up of the precipitating cupric oxide.
