Title: Specialised slide chart for axial ventilator characteristics - aids selection of suitable ventilator by presenting data conveniently in box windows
Inventor: HOFMANN HANS
IPC: G06G1/00
Filed: 1976-11-15
Abstract: The slide chart contains information on axial ventilator characteristics such as pressure drop achieved, axial speed, noise level and other data, which are presented in the form of figures in windows in a simple slide rule. The data is presented is significantly easier to use than the same data presented as a catalogue. The flat plate slide (3) carries an array of data which is slid to and fro as required inside a flat box (1, 2) so that the relevant corresp. data appear in an array of small windows (8a, 8b, 8c, 8d) in the box. Axial velocity, pressure drop, volume flow and so on are thus easily obtainable for any particular case. Useful diagrams are printed on the spare surface area of the outer box (1, 2).

Title: Safety copier drum interlock - uses metallic tongue as sensor to verify that drum and peripheral units are in correct position before operation
Inventor: REITNER WILHELM
IPC: G03G15/00
Filed: 1977-04-18
Abstract: An interlock mechanism prevents damage to the surface of the drum in an electrostatic copier. Damage is prevented if, after changing the drum and swinging electrodes etc. away from the drum surface, all peripheral items are not correctly relocated. When a drum (F L1) has to be removed, various elements, e.g. the development appts. (AR), must be swung clear. These are usually hinged (AK) units. The interlock is a metal tongue (RE) which extends up the side of the drum when correctly located and is clear of the drum when the drum is to be changed. The mode can be determined by the difference in electrical conditions between the two positions. Switching circuitry can be operated to block operation of the copier unless all interlocks record correct location.

Title: Diffusion welding flat precision components - in stack contg. plate undergoing plastic deformation when welding pressure is reached
Inventor: MUELLER PAUL ING GRAD
IPC: B23K20/00
Filed: 1977-06-11
Abstract: The workpieces, esp. metal sheet or foil are stacked in a frame between pressure plates, possibly using several stacks sepd. from each other via intermediate pressure plates; and pressure is exerted via an adjustable clamp and by differences in the coeffts. of thermal expansion of the frame and clamp. The stack also includes a pressure-redn. plate, made e.g. of mild steel, which undergoes plastic deformation when the desired diffusion welding pressure is attained. The pref. device includes a U-shaped frame closed by a beam to form a cavity contg. stacks of the workpieces and plates, plus a clamp which consists of a pair of mating wedges. When the wedges are driven into the frame cavity the initial clamping pressure on the stack is increased. Used for welding thin, flat precision components together. The components may, e.g. have a complex shape produced by etching, and must be welded together with no plastic deformation so their exact dimensions are obtd. Such components are used in raster ink printers; in (electro)hydraulic control systems; or in fluidics.

Title: Handle and supporting metal band for glass jugs - is held firm by tangential screw drawing end pieces of band together
IPC: A47G19/12
Filed: 1977-07-12
Abstract: The peripheral metal band (2) supports the handle (3) and fits round the glass or ceramic vessel such as a coffee pot. End pieces (5, 6) are bent radially down from the vessel (1) and project into a recess (7) in the handle (3). The handle (3) itself has a screw (9) which runs at a tangent to the vessel. Its head (10) is supported on the handle and it is screwed into a threaded part (12) which can move axially but not rotate in the handle (3) and rests on an end piece (6) of the band. One end piece is thus supported on the adjoining wall of the recess whilst the other end piece is moved up to the first end piece when the screw is tightened so that the metal band is braced as a whole round the vessel so that the handle is tightly fixed.

Title: Heat producing system using water or air as source - permits all year use of heat pump, without additional heating
Inventor: GOLLNOW KLAUS ING GRAD
IPC: F25B30/02
Filed: 1977-07-15
Abstract: The heat production system contains a heat pump circuit. It has a circulating medium which comes into heat conduct when an effective heat carrier, where it liquifies, looses pressure, and evaporates in heat contact with a heat source, being then compressed in a compressor coupled to a drive engine. With reduced output demand of the compressor (1) due to a falling temperature of the heat source, the energy supplied to the compressor is reduced. The excess energy produced by the drive engine (5) is converted first into electrical energy, and finally to heat energy, which is supplied to the effective heat carrier.

Title: High precision form stable analyser tube - has gold foils transferred from core to glass tube for embedding in internal walls
Inventor: FRANZEN JOCHEN DR RER NAT
IPC: H01J49/42
Filed: 1977-11-25
Abstract: The high precision form stable analyser tube has spaced conductors embedded in the internal insulating wall.
