Title: Foot switch for control of dental equipment - has movable plate whose movement controls electronic transducer whose capacitance varies with pressure
Inventor: WIESER ALFRED
IPC: H01H13/16
Filed: 1977-05-27
Abstract: The switch controls the equipment operational functions and power. It has a case and one or several foot operated plates. The foot operated plates (1) can be moved against a preset tension in different directions allocated to the operational functions and power. By changing the point of pressure application and/or the direction of the operating pressure, the direction of movement and thus the switching on of a certain operational function is determined, and/or the applied force determines the power. These functions are carried out by the plate controlling an electronic transducer (12) whose capacitance varies with pressure.

Patent DE-2729848-A1 (DE)
Inventor: GRUENERT WOLFGANG
IPC: B60T15/42
Filed: 1977-07-01
Abstract: The said rapid braking accelerator is intended for use in indirectly acting air brakes in rail wagons and coaches in international rail traffic. It has a control piston (6) which in the closing direction of an acceleration valve controlled by it and inserted into a vent of the main air line is unrestrictably acted upon by the pressure in the main air line. On the other hand the pressure in a control chamber (8), connected to the main air line pressure by way of a restrictor, also acts on the control piston. For adaptation to brake devices with different pressures, a shut-off valve (36, 40) is arranged in the connection from the main air line to the restrictor (54). The shut-off valve is loaded in the closing direction by the pressure in this connection against the force of a spring (44). <IMAGE>

Title: Guide for aiding replacement of resectoscope cutter - is parallel to axis of tube and contacts telescoping members
Inventor: IGLESIAS JOSE J DR MED
IPC: A61B17/32
Filed: 1977-10-19

Title: Spin dryer safety stop - comprises mechanical cable operating brake through action of lid lock
Inventor: KORB KLAUS DIETER
IPC: D06F49/00
Filed: 1978-02-25
Abstract: The switch for a clothes spin dryer, located in the lid catch assembly, incorporates a stop swinging on a horizontal axis, a control rocker and a locking latch. The control rocker is tipped by the lid plug and, through the swing of the stop on its axis, moves orthogonally on a horizontal axis against a return spring so that it is freed from the lid plug as the stop is operated. The core of a 'Bowden' (RTM) is connected to the other side of the control rocker, leading to the brake unit. The brake unit has a friction force transmission directly or indirectly connected to the other end of the 'Bowden' (RTM) cable core. The cable, on operation of the rocker released by the lid plug, rocks back at least over a section of the rocking path while the control rocker releases the latch. The design gives a fully mechanical operation to ensure safety and stoppage in the spin dryer; there are no electrical components in the system.

Title: Distance measurement by continuous averaging of successive results - using register to store one less than total signals determined by counter
Inventor: ERICSSON LARS AXEL
IPC: G01S17/08
Filed: 1978-03-30
Abstract: Distance measurement process involves continuous averaging of a series of distance measurements carried out one after the other on a single target. The result of each measurement and associated averaging calculation is displayed and represents the most probable distance. A counter determines the number N of recorded measurement signals. A register stores the average value for N-1 signals, the value for 1 received signal being set to zero. The average value is subtracted from the measurement signal value and the result divided by the number of received signals. The division result is added to the average value to produce the displayed result.

Patent DE-2827536-A1 (DE)
Inventor: THEIHSEN HANS
IPC: D02H5/00
Filed: 1978-06-23
Abstract: Threads (21) are wound around onto a warp beam (3) by the warping drum (1) of a cone warping machine. The warping drum (1) and/or the warp beam (3) are displaced laterally relative to one another according to the decreasing winding thickness by means of an electromotive travelling drive (7) which causes a traversing of the threads (21) running onto the warp beam (3). In order to adjust or to change the traversing in as fault-free a manner as possible before and during the winding round, a control voltage of the electromotive travelling drive (7) is heterodyned with an alternating voltage which is of adjustable amplitude and the frequency of which is determined as a function of the winding speed of the threads (21). <IMAGE>

Title: Screw conveyor with mixing action - having inclined screw rotating at high speed with feed hopper for additional component
Inventor: WEBER KARL-JOSEF
IPC: B01F15/02
Filed: 1978-08-10
Abstract: Screw feeder serves to mix in additive to particulate which is being conveyed. The additive is dusty powder held in a small hopper on the side of the screw conveyor. The latter is rotated at relatively high speed and induces vibrations in it. This vibration is transferred to the feed hopper for the additive which is rigidly mounted on the side. The flow of additive can be controlled by a slide valve underneath the hopper. For use with agricultural drilling machines where the seed corn is disinfected immediately before sowing. Disinfected seed cannot be used for other purposes, so the system allows the treatment to be carried out on the machine.

Title: Photographic printer exposure assessor - measures by spot or area and compares colours algebraically with reference density
Inventor: THURM SIEGFRIED DR
IPC: G03B27/73
Filed: 1978-09-15
Abstract: Exposure factors for a photographic printer are determined by scanning the negative, either by area or spot measurements with photoelectric cells. The negatives are spliced together and fed through the printer in a continuous length. The equipment measures a basic density of the whole negative, densities of specific parts, densities for the individual colours, difference densities for each combination of two of the three primary colours, and by recording these measurements for a number of areas or spots of the negative of varying characteristics. By algebraically comparing the results an exposure is computed. Before the film reaches the exposure point it is scanned by the measuring head and the results fed into the microprocessor controlling the printing filter and exposure control circuit and operating motors.
