Title: Submarine locating system with ultrasonic transmitter - has acoustic wave receiver, whose active face is adjacent to specified body
Inventor: ROHR ALFONS
IPC: G01S11/16
Filed: 1992-01-13
Abstract: The ultrasonic transmitter sends out acoustic waves, whose echo is received by a receiver with the echo display. For this purpose a conventional acoustic wave receiver (4) is used with a body (7), adjacent to the receiver active surface (6), of a material with a higher propagation velocity for the ultrasonic waves w.r.t. the ambient medium. The body has a plane (8) inclined to the active surface. The plane is so aligned that the impinging echo waves from the monitored object (2) pass towards the active surface after the diffraction during entry into the body. The body is pref. of iron. USE/ADVANTAGE - For submarine echo locating system. Has facility for forming object contour on display screen and object identifying.

Title: Minimisation of plasma effects on capacitative sensing systems - comprises using tool and sensor frequency generator having the same reference potential
Inventor: ALBERT HANS JOACHIM
IPC: B23K7/10
Filed: 1992-02-08
Abstract: The method minimises the disturbing effects produced by plasma on capacitative sensing systems, on thermal cutting machines, with a potentially sepd. mounting and a potentially sepd. voltage supply. It is characterised by the fact that the tool (2), as one of the sensing elements, has the same reference potential as the frequency generator (1) of the sensor (4). The tool (2) is a torch or a nozzle (7). Such a tool or its parts are insulated relative to the thermal cutting machine. The workpiece (5) is connected to an alternating voltage generator (1) and is supplied with an alternating voltage signal. Hence it acts as a sender and faces the sensor (4) designed as a receiver. This sensor is connected to a unit (8) which evaluates the field variations. USE/ADVANTAGE - The invention can be used with a variety of thermal cutting machines, where exact setting of the tool height above the workpiece is of great importance (from the viewpoint of efficiency of the cutting operation and quality of the cut). It is an improvement of known methods used currently to minimise plasma effects on the tool setting accuracy.

Patent DE-4221676-A1 (DE)
Title: Winding yarn on ring spindle during doffing - uses self-cleaning teeth to hold a single yarn turn which do not accumulate waste yarn
Inventor: WOLF HORST
IPC: D01H9/16
Filed: 1992-07-02
Abstract: Yarn is wound on the waste retaining region of a spindle on e.g. a ring frame, in a wavy manner. The region is profiled so that the yarn is held in a wavy line by edges. When a full package is to be doffed, the ring rail is lowered and a single turn of yarn is wound so that it is held between teeth. As the full package is removed the yarn breaks between the teeth and the package but is held between the teeth and the traveller. When a new tube is in place, the ring rail is raised and the yarn starts winding on the tube, the yarn automatically removed from the teeth so no further cleaning is required. The construction of the holding teeth depends on manufacturing convenience. Alternatively a wavy yarn turn can be produced by traversing the yarn, e.g. by rapidly raising and lowering the ring rail. USE/ADVANTAGE - The invention avoids the accumulation of waste yarn on the spindle which occurs with the conventional method of winding 3 - 5 turns to hold the yarn during doffing.

Title: Hydraulic fluid pressure controller for antilock braking system - prevents fluctuations in master cylinder due to return of fluid from pump through flow control valve.
Inventor: ANDO HIROMI
IPC: B60T8/42
Filed: 1992-11-06
Abstract: A solid cylindrical slider (31) in the housing (10) of the flow control valve (8) limits the passage between the pump connection port (15) and the master cylinder port (11) so that outlet pressure from the pump (25) does not act directly on the master cylinder (1).
