Title: Commutator manufacture for DC machine - using cast bars held by temporary bridging ring whilst clamping rings are fitted into V=shaped grooves
Inventor: VOLKRODT WOLFGANG DR ING
IPC: H01R43/06
Filed: 1979-07-17
Abstract: The application of the proposed commutator manufacturing method is to small quantity production. It is intended to eliminate most of the time consuming hand work previously involved in the manufacture of individual commutators. The commutator bars (2) are cast joined to a temporary bridging ring (1) which holds them all together. A space is left between each bar. The V-grooves (6) for the clamping rings are then machined into each end followed by fitting the rings (9) made of insulation material. The rings are bolted together (11) in the normal manner. When the clamping bolts (11) are tight the bridging ring (1) is machined off. The spaces between bars are then filled with insulation resin which, when cured, provides the necessary isolation between adjacent bars.

Title: Gun barrel curvature measuring technique - using laser beam reflected by mirror on plug, opto-electronic device and computer
Inventor: HESSBERG HELMUT DR
IPC: F41A31/02
Filed: 1979-07-28
Abstract: Straightness of a gun barrel is measured by passing a close fitting plug through the bore at uniform speed. The axis of the plug aligns itself with the local tangent to any curvature. A laser beam directed down the bore is reflected by a mirror on the plug. Deflection of the reflected beam is measured by an opto-electronic device and fed, together with distance along the barrel, to a computer. The computer calculates the position and radial orientation of curvature peaks, using a 'differential geometry' method, and stores the results. The stored data is then used to position the anvils and set the stroke of an automatic straightening machine. The bore is then re-measured and straightening repeated if necessary until within tolerance.

Title: Paper-making cylinder - has condensn. syphon shoe layout to prevent local over-drying
Inventor: SCHIEL CHRISTIAN
IPC: D21F5/10
Filed: 1979-07-31
Abstract: The syphon shoes in the individual drying cylinders, for the water condensn., are spread along the length of the cylinder. The thermal insulating rings, which allow condensn. to pass through, are placed in the drying cylinders so that there is a lower applicn. of heat to the paper web where there is an overdried strip from the syphon of a preceeding cylinder and to compensate for it. There is only one syphon shoe in each drying cylinder, located at the steam inlet side. The syphon is spaced (a) from the end of the cylinder in one section, and at another gap (b) in another cylinder section, with their difference (a-b) being at least the width of a syphon jet. The design allows the use of a stationary syphon, drying the paper web equally across the whole width, without overdrying web strips where there are a number of syphons in sequence.

Title: Mine cutting plane drive chain break repair - involves consecutively releasing clamping of idle and loaded lengths, and stressing
Inventor: DIENBERG HORST
IPC: E21C29/06
Filed: 1980-03-05
Abstract: The monitoring device prestressed onto the cutter chain, and a downward-spaced device, controlled by this, clamping the cutter chain loaded and idle lengths, form a cutter chain interceptor assembly. It is used to eliminate a break in a drive chain for a planing device on a cutting machine in a mine. The cutter chain (13) is loaded on one side for monitoring and clamping, and prestressing is then released, and the end of the idle chain length above the clamping area is drawn up and tightened. Clamping of this length is released, and it is tightened from top drive to plane, and then connected to the chain end above the loaded length's clamping area. This clamping is released, and the whole chain drive is then stressed. Following repair, the chain again passes correctly through the monitoring and interceptor devices, and chain drive is closed by a repair link.

Title: Expresso coffee machine with brewing head ensuring constant foaming - has partially closed sieve insert ensuring build-up of pressure prior to delivery
Inventor: WIRTZ PETER
IPC: A47J31/06
Filed: 1980-09-18
Abstract: In the brewing head the sieve insert (40) which is provided for the ground coffee is closed on the side of the sieve (52) remote from the coffee where it has an outlet opening (55) which is closed by a spring- biased non-return valve (56). This has the effect of increasing the pressure in the brewing head so that the coffee drink runs into the cup forming the required foam. Since a higher pressure occurs in the sieve insert compared with conventional expresso machines with an open outlet it is preferable if the sieve insert has an outwardly protruding flange which grips over the upper edge of the brewing head to lie against a bearing face of the brewing head connector fitting.
