Title: Stranding machine spool holder - has dual fluid-pressure system to operate mechanical locking action and pre-stress frame
Inventor: GENSICKE WOLFGANG
IPC: B65H49/26
Filed: 1980-11-15
Abstract: Spool holder for radial stranding machines, spool winding machines, etc., has two independent fluid-pressure systems, pneumatic or hydraulic, to close and to open a mechanical locking device, and which also provide pre-stressing of the frame of the holder. The locking device comprises a rotatable castellated ring which is rotated under the action of a coil spring to lock behind a similarly-profiled section of the inner surface of the hub. The castellations form a series of chambers which can be pressurised by the working fluid to unlock the ring against the pressure of the spring. In one bearing is a compression spring acting axially on the spool via the bearing, which is compressed by the second fluid system acting axially on the spool via a pressurised cylinder in the opposite bearing. The spool is securely locked in the holder, and safe from accidental release. The system can be remotely operated, and is suitable for use in a fully-automated machine.

Title: Arrangement for the electrical heating of mixture
Inventor: HEUER HEINRICH
IPC: F02M31/135
Filed: 1981-03-18
Abstract: In an arrangement for the electrical heating of a fuel-air mixture flowing through an intake pipe connected to the output side of a carburettor of an internal combustion engine, a heating resistor is fitted inside the intake pipe. It is intended that this heating resistor be formed as a flexible mat-shaped heating element which rests on at least one part of the internal circumferential surface of the intake pipe. In the case of a forking intake pipe, it is intended that this be divided essentially horizontally in the area of the fork and that the heating mat resting on the internal circumferential surface of the bottom part of the intake pipe be held clamped between the two parts of the intake pipe. For this, it is advantageous if the heating mat is held in a recess on the internal circumference of the bottom part of the intake pipe.

Patent DE-3119801-A1 (DE)
Title: Hydraulic control device
Inventor: SANDAU HARTMUT ING GRAD
IPC: B60T13/14
Filed: 1981-05-19
Abstract: The control device has a flow-control valve (15), an accumulator-charging and pilot-control valve (52, 54), and a brake valve (93) which can be actuated via a pressure transmitter (127) and has a pressure-reducing function. If the pressure in the accumulator (67) has dropped below a certain limit value, it is charged via the flow-control valve. Pressure medium which continues to be delivered by the pump flows to the consumer. The brake device is fed exclusively by pressure medium from the accumulator. The feed line from the control device to the accumulator (67) is divided into two branches (65, 66 and 78, 79). Thus undesired pressure fluctuations in the control device which are caused during the braking are avoided. <IMAGE>

Title: Thermophotographic recording material
Inventor: KINOSHITA SHOZO
IPC: G03C1/498
Filed: 1981-05-29
Abstract: The present invention relates to a thermophotographic recording material containing, in one or more layers on a substrate, a) a non-photosensitive organic silver salt oxidising agent, b) a reducing agent for silver ions, c) a silver halide component or a component capable of forming a silver halide component by reaction with the organic silver salt oxidising agent a), d) a toner and e) a lipophilic binder, which is characterised in that a specific 2-(2'-hydroxyphenyl)-benzotriazole compound which has bulky tert-butyl or tert-amyl groups in the ortho- and para-position to the hydroxyl group is present in the layer which contains the component a). The recording material according to the invention has a very long shelf life before it is used. If the recording material is a combination of a layer which contains a silver salt oxidising agent and in which the specific 2-(2'-hydroxyphenyl)-benzotriazole compound is present and a layer which contains a reducing agent and in which a highly impact-resistant acrylic resin is present as a binder, the untreated (crude) recording material has a substantially improved shelf life in the dark or in the light having wavelengths of 450 nm or more, improved stability of a latent image and minimum deviations in the image quality as a function of the thermal development conditions. If the recording material contains, as component a), a silver salt of a long-chain fatty acid having 16 or more carbon atoms and, as component c) a silver halide component containing silver iodide, or a component forming a silver halide component containing a silver iodide, and furthermore contains g) an oxidising agent for free silver, h) a photoreactive halogen-containing oxidising agent and, in the layer which contains the components a), c), e) and f), i) a specific spectrally sensitising cyanine dye, it is a recording material of the postactivation type which is spectrally sensitised without the shelf life of the untreated (crude) recording material being adversely affected.

IPC: G01L23/22
Filed: 1981-07-16
Abstract: A device for detecting knocking in internal-combustion engines is proposed which has at least one sensor which measures the ion current. A comparison device compares the ion-current signal of an ignited cylinder with the ion-current signal of a non-ignited cylinder. In this arrangement, the latter signal serves as a threshold value. This threshold value can be varied by supplying an additional voltage. If the ion-current signal of the ignited cylinder overshoots the threshold value, the comparison device emits a knocking detection signal. <IMAGE>

Patent DE-3136492-A1 (DE)
Title: Arrangement for detecting the vibrations occurring during knocking of an internal-combustion engine
Inventor: BOENING BERNHARD DR ING
IPC: G01L23/22
Filed: 1981-09-15
Abstract: An arrangement is proposed for detecting the vibrations occurring during knocking of an internal-combustion engine, in which use is made of a narrow-band knocking sensor whose bandwidth is tuned to the bandwidth of the knocking frequencies which occur. The bandwidth of the knocking sensor is set substantially lower in this case than the knocking frequencies which occur, since the knock phenomenon occurs not as a continuous signal but only in a few vibrations, with the result that the knocking phenomenon is a broad band one as a whole. It is preferable to use as knocking sensor a partially encapsulated (potted) flexural vibrator whose bandwidth is set by selecting the hardness of the casting (sealing, moulding) compound. <IMAGE>

Title: Office hole-punch
Inventor: PFORDTE FRANZ DIPL ING
IPC: B26F1/36
Filed: 1981-11-28
Abstract: In order to file loose sheets in ring binders, four holes are often needed in the lateral edge of the sheet. Irrespective of the format of the sheet, these four holes can be punched with a two-hole punch if the two outer holes are positioned on the basis of the two central holes. To this end, a hook is arranged in front of each punch, above the punching level, which is at the same distance from the other punch as a central hole in the sheet is from the outer hole. If a central hole is threaded over the hook, the punch lying behind it goes down in front of the edge of the sheet, while the other punch punches an outer hole in the sheet, which is positioned obliquely to the hole-punch. See drawing Fig. 4. A mark is positioned close to each punch, by means of which an individual hole can be placed at any point which is marked by a line transversely to the edge of the sheet. The centre of the sheet and distances between holes for conventional arrangements of the holes are marked at the edge of the hole-punch. This hole-punch is intended for office and domestic use. <IMAGE>
