Title: Central heating boilers asbestos insulation - uses wet asbestos layer applied directly to metal sides of boiler
Inventor: WELLERDIEK KARL-HEINZ
IPC: F24H9/02
Filed: 1976-03-15
Abstract: The insulation is for oil, gas and solid fuel central heating boilers. The sheet metal cladding of the boiler is removed, and a wet layer of asbestos is applied directly to the boiler surface. The asbestos may be applied in a single layer which is then allowed to dry or several layers may be applied. Each layer in turn may be allowed to dry before the neat layer is applied. The layers may be sprayed on or they may be applied by some other means, and intimate contact is achieved between the asbestos and the sides of the boiler.
Patent DE-2612925-A1 (DE)
Inventor: RUBEL ERICH DIPL ING
IPC: G05D1/02
Filed: 1976-03-26
Abstract: The vehicles are guided sideways by a guide wire (12) which is laid along the roadway and through which a low-frequency alternating current flows. Two control cables (L1, L2) with the same amplitude (A) and wavelength  lambda  are arranged symmetrically with respect to the guide wire (12) offset with respect to one another by  lambda /4. The control cables also have alternating current flowing through them, the frequency of the said current being expediently twice or three times as high as the frequency in the guide wire (12). As a result, a travelling wave is produced along the roadway, the wavelength of the said travelling wave being freely selectable within wide limits when the control cables are laid and it being possible for the speed of propagation of the said wave from a feed point to be controlled. This travelling wave is used to control the speed of the vehicles which are thus guided along the roadway at predetermined intervals. <IMAGE>

Patent DE-2614933-A1 (DE)
Title: Removal of nitrogen oxides from pickling bath off-gases - using permanganate or dichromate solutions for oxidation purposes followed by alkali scrubbing
Inventor: ULLRICH HANSJUERGEN DIPL ING D
IPC: B01D53/56
Filed: 1976-04-07
Abstract: From the acid treatment bath the off-gases are passed by a fan to a wash column with pumped circulation, in which the NO2 in the gas is taken out by water washing, as weak nitric acid. The gas then flows to a similar circulated column in which it is in contact with the oxidising solution of permanganate or dichromate, which converts the nitric oxide to nitrogen dioxide. There follows a final absorber having a circulation of alkali solution in which the NO2 produced by the NO oxidation is taken up as a nitrate solution. Used for the treatment of the off-gases from metal pickling baths using nitric acid or a mixture of nitric and hydrofluoric acids. The NO content of the gases is removed along with the NO2.

Title: Magnetic sound track for cine film - with additional track on opposite side used as frame indexing memory
Inventor: PROCHNOW CLAUS ING GRAD
IPC: G03B31/02
Filed: 1976-04-23
Abstract: The narrow cine film has a magnetic sound track on one side of the film, and a similar track on the other side, away from the sprocket holes. The additional track is applied to the uncut, wide film, as two parallel tracks, with cutting between the tracks. When the film is cut the additional magnetic track provides an even thickness to both sides of the film, so that it is wound evenly on the reel. The additional track is also used as a frame indexing memory. In the projection equipment an additional sound head monitors the extra track so that editing and frame retrieval is simplified. The frame indexing is also used for controlled double exposure sequences between scenes.

Title: Printer with contactless electrostatic printing head - ion concentration between writing electrode and paper reduces transfer voltage
Inventor: DREYFUS RUSSELL WARREN
IPC: B41J2/41
Filed: 1976-05-03
Abstract: Contactless printer with an electrostatic printing head and a writing electrode is characterised by an arrangement to produce a constant corona discharge for the ionising of a gas. These ions are fed into the space between a writing electrode (14) and the paper carrier (16) in order to reduce the voltage required to effect a flow from the writing electrode to the paper. The writing electrodes are selectively controlled with writing impulse whose amplitude is at least that of the transfer voltage. The physical properties of the paper used change in dependence with the transfer of the writing flow.

Title: Blood pressure measurement by Riva:Rocci:Korotkoff method - uses switch for opening or closing valve for cuff and needles locked by signals from Korotkoff noise
Inventor: AFFELDT KARL-HEINZ DIPL ING
IPC: A61B7/04

Title: Conveyor with individually driven rollers - has measuring wheels delivering pulses to counter representing length of work
Inventor: KRAECHTER WERNER ING GRAD
IPC: B65G47/42
Filed: 1977-04-15
Abstract: The roller conveyor has individually driven rollers. It transports oblong work of varying lengths in the lengthwise direction this being then taken over by a transverse conveyor after the roller conveyor has been switched off. This occurs at the moment when half the length of the work has passed the vertical plane through the transverse conveyor centre line. On the input side of the leading roller (13, 14) is a central measuring wheel (19) driving a pulse emitter, delivering one pulse per unit of length of the work transported (18) to a counter. A second pulse emitter is driven by a measuring wheel mounted centrally below the roller conveyor, and on the centre line of the transverse one. For each unit of length of the work this delivers two subtracting pulses into the counter.

Title: Tunnel driving system with simultaneous concreting - has segments formed in succession in peripheral direction using internal shuttering only
Inventor: STUCKMANN DIETER
IPC: E21D9/06
Filed: 1977-06-08
Abstract: The tunnel and gallery driving system uses a shield with knives, simultaneously installing concrete cladding by the delivery of concrete into a space formed by shuttering. The shuttering components are attached to the shield and moved as excavation and concreting procede. The concreting is effected by forming concrete segments in succession in the peripheral direction, without the use of external shuttering. The components forming the multi-section internal shuttering are advanced successively in the tunnelling direction so as to form sections of concrete, either individually or in groups. The internal shuttering sections can be advanced with the tunnelling knives, concrete being introduced into the cavity so formed, and typically via the knives, simultaneously with advancement of the sections.

Title: Stereoscopic motion picture scanning method - uses optical film scanner with projection optics on inside of circle producing erect picture on circular viewing screen
Inventor: COLLENDER ROBERT BRUCE
IPC: G03B35/04
