Patent GB-2087581-A (GB)
Title: Photographic Process
IPC: G03C1/485
Filed: 1981-11-17
Abstract: The invention relates to photographic processes in which a photographic reagent, such as a development inhibitor, is released from a carrier group. Development inhibitor-releasing (DIR) couplers and compounds release the development inhibitor on reaction with oxidised colour developing agent. Some photographic colour processes, such as colour image transfer processes, can be carried out using black and white developing agents: a colour developing agent is not necessary and the presence thereof could cause stain. We now provide a photographic process which can be carried out using certain black and white developing agents and in which a development inhibitor or other photographic agent is released, said process being one in which an  alpha - substituted ketone or imine having a photographic reagent moiety bonded to the  alpha -carbon atom through a hetero atom or through a hetero atom and a timing group reacts under alkaline conditions with an oxidised 3- pyrazolidone developing agent to cleave the hetero atom or timing group from the  alpha -carbon atom and thereby to release the photographic reagent directly or by the operation of the timing group respectively. Photographic assemblages containing said  alpha -substituted ketone or imine and a 3-pyrazolidone developing agent are also provided.

Title: Method and apparatus for determining the shape of objects
IPC: G01B11/245
Filed: 1981-03-31
Abstract: An apparatus for determining the shape of an object such as an exhaust pipe comprises a carriage (11) which carries a scanning unit (10) and is movable by a motor (22) along a base (12) having supports (17) for the object. The scanning unit comprises two laser units (37) the light beams of which are directed by rotating mirrors (42) towards two parabolic mirrors (35), the beams being reflected by the latter so as to traverse the object at right angles to one another and in a common plane at right angles to the movement of the carriage. The beams are interrupted by the object, and light-responsive means (38) detect such interruption to determine the shape of the object. In a modification, the apparatus has two or three rotating laser units (50). <IMAGE>

Title: Lifting gear for e.g. a fork-lift truck
IPC: B66F9/08
Filed: 1982-01-15
Abstract: Lifting gear, for example for a fork-lift truck, comprises upper and lower telescoping mast assemblies (4, 3) which are displaceable relatively to each other by hydraulic lifting means to raise and lower a lifting carriage through the intermediary of a pulley/ chain mechanism (23, 2). Each mast assembly comprises two upwardly extending members (5 or 12) which are interconnected, by members (13), or (7) and (8), at the ends away from the other mast assembly. This leaves the central part of the mast assembly unobstructed, providing good visibility to an operator. Visibility is also enhanced by forming the members (5) of the lower assembly (3) with cylindrical portions (10), (Figure 6) which accommodate the lifting means. <IMAGE>

Title: Waveform encoding method
Inventor: KING REGINALD ALFRED
IPC: H03M7/46
Filed: 1985-06-27
Abstract: An encoding method for an anologue waveform, such as a speech waveform comprises deriving a digital data stream from the waveform, dividing the digital data stream into a number of successive time frames of equal period and storing the data. A stream of time encoded symbols is also derived from the analogue waveform, divided into successive time frames corresponding to those of the digital data stream. The distribution of the time encoded symbols for successive time frames is determined and a digital data stream for subsequent decoding is reconstructed from the digital data stored in combination  with derived digital data which is dependent upon the results of the comparison of the encoded symbols.
