Patent DE-1806212-A1 (DE)
Title: Signalling device for use in boreholes
Inventor: L ALDER ROBERT
IPC: E21B47/024
Filed: 1968-10-31
Abstract: Drill down-the-hole position signaller produces pulses in the mud to indicate position, in terms of tool etc. angle which can then be corrected for onward drilling. A pendulum is used which responds to gravity and produces pulses according to the angle relative hole bottom by reacting with a number of spatially divorced, angularly increasing stops. The number of pulses produced depends in this way on the stop the pendulum contacts, the pendulum being directed towards hole bottom and the stop fitted at selected positions for the pulsing operation.

Abstract: An automatic noise filter may be used to remove noise from the desired signals, and may be formed by using a star, or triangular filter network, at the centre of which is placed a diode trap or gate. The operation of the network is such that noise signals which penetrate the filtering circuits are neutralised by the diode trap. On the other hand, the proper signals are not effected by the circuit since the filters are arranged to discriminate only against random noise.

Title: Hot plate temperature limiter - has temperature sensitive element exposed to the heat of an electric hot-plate
Inventor: FISCHER KARL
IPC: H01H37/00
Filed: 1973-08-30
Abstract: It interrupts or limits the current supply to the hot-plate at the set temperature by a contact. A safety contact is provided, operated by the same temperature sensitive element, which interrupts current supply at a temperature much higher than the set value. When this contact is operated once, it permanently disconnects the hot-plate owing to a locking device which keeps the contact open after its single operation. The safety contact operates a cut-off relay for the hot-plate. The temperature sensor is of a known type, consisting of an expansion rod in a sleeve. Sensors are made of materials with different coefficients of thermal expansion.
Patent DE-2345489-A1 (DE)
Title: Signal transmission and switching system - monitors operating and standby lines and automatically switches over in case of line fault
Inventor: SCHEFFLER HARTMUT
IPC: H05K10/00
Filed: 1973-09-08
Abstract: Transmitter at each end of the lines transmit, in addition to the information signal, an additional signal over both the operational and standby lines. At the receiving and the output of the operational line is connected to the receiver input, and both lines outputs are separately connected to a monitoring device which recognises the additional signal reception or non-reception, and delivers corresponding signals to both lines. The signal for the non-reception of the additional signal through the operational line causes the lines switching over. A signalling device marks the operational and the faulty line, and delivers an alarm signal in case of a fault.
Patent DE-2360203-A1 (DE)
Title: Force measuring appts. system - uses pistons and cylinders with strain gauge bridge elements
Inventor: FUCHS PETER DIPL ING
IPC: G01G19/18
Filed: 1973-12-03
Abstract: The system is to measure the force operating on the piston of a reciprocating movement and employs a strain gauge bridge whose elements are mounted on either side f the piston on each of the two faces (F1, F2). Each strain gauge has a similar voltage applied to the diagonal. Outputs from the other diagonals are connected with the input terminals of operational amplifiers. The amplifiers are connected across a pair of resistors with their common point forming the pick-up for an output amplifier. The mechanical force fed to the piston depends on the load applied by an external lever system and the frictional loss at the walls of the piston and its drive rod.

Title: Enlarged borehole foot caliper - has rope-actuated toggle levers pivoted in carrier
Inventor: HILBERT HELMUT
IPC: E21B47/08
Filed: 1974-01-26
Abstract: The enlarged foot at the bottom of a hole bored in the ground for cast-in-place piles can be measured by several swinging arms with feelers which are suspended in a carrier lowered into the borehole. The feelers can be swung out by a rope pull until they touch the walls of the cavity. The amount of swing is determined by the movment of a rod with a scale. A potentiometer slider can be used to provide a remote indication to the surface. The apparatus provides more accurate information about the size of the enlarged foot than a rod with a cross arm for a feeler. The scales can be replaced by a rotary potentiometer around the pivot or a linear potentiometer along the sleeve so that direct readings can be takne on the surface.
