Patent GB-2130536-A (GB)
Title: Hub sleeve for a cycle hub
Inventor: DEMBINSKI WALTER
IPC: B60B27/02
Filed: 1983-11-18
Abstract: The sleeve body (21) is formed as a one-piece light metal die-casting, on which two spoke flanges (23, 25) are cast or secured. On the inner circumference of the sleeve body (21) there are cast seating surfaces (33, 37) for ball bearing shells (31, 39) which are fixed axially by stop faces (35, 45) facing axially away from one another. At least one (45) of the two stop faces is provided on radially inwardly protruding ribs (43) formed integrally on the sleeve body (21) and arranged axially between the seating surfaces (33, 37); their stop face (45) merges in each case into a pocket (41) which is sunk radially outwards into the adjacent seating surface (37). While the seating surfaces (33, 37) are shaped by one common core of the same die-casting mould half, the pockets (41) in each case receive the cores of the other mould half which shape the stop face (45). The mould halves can shift radially during the die- casting without affecting the concentricity of the seating surfaces (33, 37). <IMAGE>

Patent GB-2160077-A (GB)
Title: Electric signal frequency changer
Inventor: LAWSON BERNARD JOHN
IPC: G01R13/34
Filed: 1984-06-01
Abstract: In display apparatus, e.g. an oscilloscope, the frequency of a repetitive electric signal Fx is changed by means including means to sample a first signal at varying intervals with respect to a reference point in the signal and means to form the samples obtained thereby into a second signal F2 having a waveshape similar to that of the first signal. Trigger circuit 2 derives trigger signals from the input signal Fx which are then rate reduced by divider 6. The trailing edge of these rate reduced pulses is used as a trigger reference for pulse width modulator 7. Scanner circuit 8 produces a slow speed ramp under the control of time base circuit 9. The ramp controls the width of pulses from the pulse width modulator 11. The sampling means 3 takes samples at times controlled by the trailing edges of the pulses from modulator 11. Therefore the system samples the input waveform Fx at slightly different points every few cycles to produce the low frequency waveform F2. <IMAGE>

Title: Capacitive moisture sensor and process for producing same
Inventor: HEGNER DR FRANK
IPC: G01N27/22
Filed: 1984-10-11
Abstract: The capacitive moisture sensor is formed by the use of the thin-film art on a moisture-insensitive insulating substrate (1). A structured electrode (2) is formed as a base electrode on the substrate. The base electrode is covered with a thin, moisture-sensitive film of polyimide (7). On the polyimide film there is arranged a top electrode (8) which is structured to be substantially complementary to the base electrode (2). Between the structured base electrode (2) and the moisture-sensitive film (7) a moisture- insensitive electrically insulating film (3) can be arranged which is formed preferably by surface oxidation of the structured base electrode. The production process includes the feature that to form the moisture-sensitive film first of all a polyimide precursor is applied, then this is structured in accordance with the desired form of the moisture-sensitive film, and then the polyimide precursor is imidised for conversion to moisture-sensitive polyimide. <IMAGE>

Patent GB-2155582-A (GB)
Title: Hydraulic tension mechanism for a chain or belt
Inventor: ABTS M
IPC: F16H7/12
Filed: 1985-02-01
Abstract: A mechanism for hydraulically tensioning a belt (or a chain) has a piston (6) which moves in a housing (5) and can be hydraulically extended from the housing to exert a tensioning force on a belt. To prevent the piston being pushed back into its housing and thereby allowing the belt to slacken, a locking sleeve (16) is provided. The piston locks against this locking sleeve through a ring (27) which is accommodated around the sleeve and in a groove (26) in the end of the piston. The surface (28) of the groove facing the ring is tapered so that the piston can move freely over the locking sleeve (16) in one direction, taking the ring with it. On movement in the other direction however, the ring is cammed by the tapered surface against the locking sleeve so that it jams and prevents the piston from moving relative to the sleeve. The piston is thus locked. <IMAGE>

Title: Apparatus and methods for coating substrates
Inventor: PINKHASOV EDUARD
IPC: C23C14/22
Filed: 1985-03-08
Abstract: Quartz crucibles (710) as illustrated in Fig. 8 for the melting of silicon and ceramic substrates are coated with protective materials (710') or metals at least in part evaporated from an electrode (701,702) with which an arc is struck at low voltage and current to deposit material from the electrode (701 or 702) on the substrate in a vacuum chamber. The electrode (701,702) may be heated and the substrate (710) may be sandblasted and preheated. Specifically a method of coating a quartz crucible for use in the melting of silicon comprises the steps of juxtaposing a pair of electrodes, composed of at least one component of a material adapted to coat said crucible, with an interior surface of said crucible; evacuating the space in which said electrodes are juxtaposed with said surface and maintaining a fixed pressure during deposition; and striking an electrical arc between said electrodes at one end of each of said electrodes at a voltage in the range 30-60 volts and with a current in the range 50-90 amperes by intermittently bringing said electrodes into contact with one another and separating them, thereby depositing material evaporated from said electrodes substantially over said interior surface of said crucible. <IMAGE>

A booster and charger circuit (5) increases the voltage level of the second power source in accordance with the voltage detected by the detector circuit. The booster and charger circuit is located between the second power source and the timepiece movement circuit so that the voltage level applied to the timepiece movement circuit is, in operation, greater than the first predetermined voltage level when the voltage level of the second power source is less than a second predetermined voltage level. <IMAGE>
Patent GB-2155949-A (GB)
Title: Fluid bed biological reactor
Inventor: CROCKER PETER JOHN
IPC: C12M1/40
Filed: 1985-03-22
Abstract: In an intensified process for the fermentation of microbes to produce biomass in a liquid medium in a reactor containing particles, the liquid medium has a specific gravity that is lower than the specific gravity of the biomass and which is higher than the specific gravity of the particles. In the process the particles are maintained as a fluidised bed by downward fluidisation by upflow of gas and/or mechanical agitation. The biomass grows on the surface of the particles during germentation and is knocked off the particles in the bed. The biomass and liquid medium are separated, generally within the reactor, and removed from the reactor. The process is usually a continuous process and is useful for reducing the biochemical oxygen demand of waste water. Novel apparatus for carrying out the continuous process comprises a reactor having inlet means for liquid medium and outlet means for liquid medium and biomass in which the inlet means is higher than the outlet means and the reactor contains gas diffusers above its base.
