Title: Long fur strip cutting method - by curved line of cut on short animal skin
Inventor: GROSSE-SEGERATH CLEMENS
IPC: C14B15/10
Filed: 1980-04-16
Abstract: Strips of fur for the assembly to a fur coat or jacket are cut from an animal skin by directing the cut from near the top edge diagonally towards the centre and then in a closed curve back to produce a lost drop-shaped piece. The skin is then opened out and stretched in a wet state to a shape of a slender truncated cone. Other shapes can be produced by different lines of cut. This produces fur strips of much greater length than the length of an animal skin.

Title: Automatic measurement of relatiVe frequency and phase deviations - uses signal counted according to relative time count durations
Inventor: BEETZ HEINZ ING GRAD
IPC: G01R25/08
Filed: 1980-09-03
Abstract: The method and arrangement for measuring relative frequency and phase deviations perform the measurements automatically as opposed to manually using a stopwatch and standard curves. A reference frequency signal is used to derive a first time unit. A second time unit is derived from the measurement signal delayed according to the reference frequency. Counting from a centre value begins at the start of the first time unit and ends at the start of the second time unit. The count is repeated or performed in the opposite direction depending on whether the first time period ends after or before the second. The second count ends with the later time period and its result is stored digitally and displayed. The first and second time unit counts give the phase and frequency deviations respectively.

Title: Method of ageing semiconductor gas probes
Inventor: SHIN YASUO
IPC: H05B6/80
Filed: 1981-04-23
Abstract: A method is described for ageing an SnO2 semiconductor gas probe for checking the cooking state in cooking utensils. To stabilise the measuring characteristics of the probe, the method is to age the SnO2 semiconductor gas probe in a gas atmosphere containing a gas which is formed in the apparatus in which the SnO2 semiconductor gas probe is to be installed. Preferably, the gas atmosphere contains gaseous dimethylsiloxane which is released from a heated silicone compound. The gas atmosphere is kept during the ageing treatment, for example, at a temperature of 150 to 250 DEG C, as a result of which an SnO2 semiconductor gas probe is formed whose resistance value and whose sensitivity are stable even in a high-temperature ambient when, for example, a cooking process is carried out in the cooking utensil.
Patent DE-3117655-A1 (DE)
Title: Device for maintaining distances between track-bound vehicles
Inventor: KRAUS PETER DIPL ING
IPC: B61L23/14
Filed: 1981-05-05
Abstract: The invention relates to a device for automatically maintaining distances between vehicles (1.0, 1.1, 1.2 etc.) which are equipped with transmitters (4) and receivers (5) and follow one another along a route which is subdivided, for signalling purposes, into route sections and has on each route section route markings for determining position on the part of the vehicles. In this arrangement, the safeguarding (of the vehicle sequence) is effected by means of a travel-authorisation signal which is transmitted to the vehicles from a stationary transmitter (8) from the end, lying ahead in the direction of travel (3), of the respective route section via a slotted hollow conductor (6) which extends along the route and is coupled to the vehicle transmitters and receivers (4 and 5, respectively), in such a way that the signal which is propagated counter to the direction of travel and is received by the vehicle (1.0) which is located respectively ahead in the route section is passively suppressed in its further propagation along the slotted hollow conductor by this vehicle and at the same time, having been actively regenerated, is fed back into the slotted hollow conductor (6) in order to be passed on to the respective following vehicle (1.1). In order, with this safeguarding device, to differentiate reliably in the individual route section all the vehicles which endanger the safeguarding of the vehicle sequence from the other (intact) vehicles, according to the invention the respective distance from the connection point between the stationary transmitter (8) and the hollow conductor (6) can be determined per route section in the individual vehicle (1.0, 1.1, 1.2 etc.) on the basis of the travel markings and, in addition, a reference signal whose signal size is determined by the distance identified at the individual route marking can be formed for a size comparison with the travel-authorisation signal received by the vehicle, a difference in sizes of the two signals triggering braking of the vehicle. <IMAGE>

Title: Warning device
Inventor: MAERTIN LUTZ
IPC: F15B15/28
Filed: 1981-05-06
Abstract: Provided in a housing of the warning device is a conical guide element which has a bore running in the direction of its longitudinal axis. A tripping pin provided with a stop is displaceably arranged in the housing against the force of a spring, and in fact in such a way that a part of the tripping pin can be pushed out of the bore in the guide element and out of the housing. The tripping pin is held against the force of the spring by a locking device. The locking device consists of an expanding body which is provided with projections and on the one hand is supported with its expanding elements on the conical circumferential surface of the guide element and on the other hand projects slightly from the housing through an opening in the housing. The warning device is fastened in an opening of the cylinder housing of a diaphragm cylinder in the area of the diaphragm. If the diaphragm is overstretched, it bears on the locking device and thus unlocks the tripping pin. The tripping pin can be designed as an optical indicating device and/or can have electrical contacts which are connected to an electric indicating device. <IMAGE>

Title: Arrangement of main motor and auxiliary motor
Inventor: DROESCHEL HELMUT
IPC: F02B73/00
Filed: 1981-05-29
Abstract: If two motors are at times operated together with one another, a torsionally elastic connection is necessary between their flywheels (11, 12) so that their oscillation frequency lies below the idling speed. Furthermore small motors with only 2 or 3 cylinders, particularly those suitable as auxiliary motors (5), need a balancing shaft with centrifugal moment rotating at the same speed in opposition to the crankshaft for good balancing of masses. The required balancing shaft is here designed as a torsionally elastic connection between the flywheels (11, 12), so that, for example, the auxiliary motor (5) can be coupled by way of a freewheel (F) to the main motor (1) in any position without troublesome vibrations occurring. Greater fuel economy than by throttling a part of the cylinder. Simple, robust construction. <IMAGE>

Patent DE-3123107-A1 (DE)
Title: Clamps
Inventor: TILLEGREEN KIM
IPC: F16L3/04
Filed: 1981-06-11
Abstract: When using clamps with fixing pins, the clamps being of different sizes, it is, in practise, difficult for the user to identify the individual clamps when these are taken out of a packet. In order to remedy this drawback with the marking of the individual clamps, the fixing pin (4) arranged in the clamp is coloured wholly or in part, with the result that the user can identify at a glance the clamp size which he or she should use. Mounting work is facilitated and simplified to a considerable extent as a result.
