Title: Optical fibre branching arrangement - has two fibres in mitred relationship and other pair abutting mitred joint
Inventor: DAKIN JOHN PHILIP
IPC: G02B6/28
Filed: 1979-05-08
Abstract: The optical fibre branching arrangement has a first pari of optical fibres (1, 2). The fibres have opposed mitred end faces (3, 4) which abut one another. A light reflector, is provided in the vicinity of the mitred joint between the optical fibres. The reflector produces partial reflection of light transmitted across the joint into at least one other fibre (5, 6). The second fibres extend at right angles to the first fibres and have their ends (7, 8) in close proximity to the edges of first fibres by the mitred joint. The light reflector may be a full mirror, a partially reflecting mirror or a dichroic mirror.

Title: Tubular electrical filter removing dust from exhaust gas - has precipitation electrodes in monolithic packed sets on columns
Inventor: STRZELSKI JOZEF
IPC: B03C3/41
Filed: 1979-05-17
Abstract: A tubular electrical filter of vertical design, which is used to remove dust from gases. It can suitably be applied to the chemical or metallurgical industry, as well as in power stations. It is intended mainly to prevent the formation of sulphuric acid which will be discharged in the open air. The equipment contains precipitation electrodes, which are made from tubes with hexagonal or circular cross sections. The dust can be purged or vibrated from the precipitators. It is filtered through a mesh. The precipitation electrodes are inter-connected to form monolithic closely packed sets. Each set is mounted on its own support column to form a dust removal set.

Title: Two arm clamping device - has ratchet teeth on abutting faces to rotate arms when pivot bolt is tightened
Inventor: FELKEL GEORG
IPC: B25B5/04
Filed: 1979-09-21
Abstract: A clamping device consists of two arms mounted on a common pivot bolt. Each arm has a boss with a hole to receive the bolt. The abutting faces of these bosses have matching ratchet teeth so arranged that, as the boss faces are pressed together by tightening the pivot bolt, one arm rotates with respect to the other. This motion exerts a clamping force on the workpiece. In the alternative design the ratchet teeth are replaced by a steep angled screw thread in order to generate a rotary motion when the bolt is tightened.

Title: Automatic control of detergent concn. in washing machines - by photoelectric monitoring of fluorescent components in wash liquor
Inventor: BUETTNER ULRICH ING GRAD
IPC: D06F34/22
Filed: 1979-12-07
Abstract: Monitoring and controlling the rinsing process in an automatic washing machine utilises a light source and a suitable photodetector to control the addn. of washing or finishing agents such as optical brighteners to the water, and also to control the number of rinses, by monitoring the optical properties of the soln. The additives are added to the water until a pre-determined max. concn., as measured by the photodetector response, has be attained. Subsequent rinses are then performed until the concn. of brightener has fallen below a pre-set min. This method always provides the optimum amt. of additive required, irrespective of the vol. of water used, and its hardness. It ensures satisfactory results whilst economising in the consumption of water, of additives, and of power, and reducing environmental pollution.

Title: Pressure control mechanism for hydraulic pump - has control pressure in groove between moving link and bore to improve accuracy
Inventor: KLINGENBECK GEORG
IPC: F04B1/32
Filed: 1979-12-24
Abstract: The positioning piston (3) slides in a bore (2) in the casing (1), whilst a pivot (4) on the piston carries an angled lever (5,8) one end (5) of which is acted on by a spring (7). The other end (8) depresses a plunger (9) in a transverse bore in the piston. The plunger controls the connection between passages (11,12) in the axial ends of the piston. The lever (8) also presses on a sliding link (22) in a bore (23) in the casing (1). The sliding link (22) moves a control piston (21). The control pressure (16) is admitted (26) to a circumferential groove (25) on the sliding link (22). This pressure between the link and its bore (23) reduces friction and lateral forces.

Title: Anti-skid brake control valve - has inertial mass vent control on each brake cylinder
Inventor: ROSANOWSKI OSWALD JOSEF
IPC: B60T8/42
Filed: 1980-01-02
Abstract: The anti-skid brake control has inertial masses rotating around the wheel hub and operating venting valves via cam slopes on their outer faces. This provides a periodic venting related to the vehicle speed.

Title: Sacrificial anode with trigger indicating when anode is spent - where trigger moves Bowden cable to actuate visible trigger or switch
Inventor: HOESSLE LUDWIG
IPC: C23F13/22
Filed: 1980-02-27
Abstract: Parent patent described an anode immersed in a tank, e.g. a hot water tank; and when the anode is spent, a peg (7) is pushed outwards thus indicating that the anode should be replaced. In this addn. the outer end of the peg (7) is located very near one end of a Bowden cable (20), so that when peg (7) is driven outwards, cable (20) is driven in its sheath. Cable (20) is used to move a signal peg (26) which is readily visible to an observer; or can be used to close a switch contact operating a warning light or other alarm. Hot water or other tanks are often located in inaccessible places, so the peg (7) described in the main patent is not always readily visible. The invention provides an indicator that can be located on a switch panel or any other visible wall or appts.

Title: Propellant fluid in pipe injects gas from adjacent pipe - through nozzles into surrounding body of liq.
Inventor: HESS FRITZ DIPL ING
IPC: B01F5/02
Filed: 1980-07-30
Abstract: A body of liq. has gas injected into it through nozzles from a first pipe contg. the gas, using a propellent fluid injected from a second pipe running in close contact with the first pipe for at least some distance. The nozzle from the propellent fluid pipe is coaxial with the nozzle(s) which inject gas from the first pipe into the body of liq. All the nozzles are radial to their corresp. pipes and lie in the plane defined by the axes of the pipes. A single propellent fluid pipe may operate on two gas-carrying pipes. The system is used for aerating sewage tanks. The aligned nozzles are easy to clean, and with oppositely directed nozzles the reaction forces cancel each other out, improving stability. The adjacent pipes in a set can be held together by tensioned bands, obviating bolts, etc. and easily removed during maintenance.

Title: DC machine drive rotation regulation control - has regulator receiving armature current of machine drive motor via multiplier
Inventor: WEIHRICH GEORG DR
IPC: H02P7/28
Filed: 1980-09-29
Abstract: The machine rotation regulation control, accommodating varying output loadings, uses a proportional regulator together with a model of the regulation path. The regulator receives the armature current of the machine drive motor via a multiplier. This has a second input receiving the output of an integrator controlled by the armature current via a second multiplier also receiving the difference between the actual motor rotation and that provided by the model. The output of the integrator is fed to a divider inserted in the signal path after an adder receiving the output of the proportional regulator and a value proportional to the machine loading. Pref. this loading value is obtained from a mixer receiving the output of a third multiplier representing the smoothed armature current multiplied with an integrated value obtained from a second integrator. This is fed with the output of a fourth multiplier receiving the rotation difference signal and the output of the smoothing element.
