Title: Monocular reflex camera for endoscopy - beam deflected by interposed prisms to observer eyepieces for conjoint viewing
IPC: G02B27/14
Filed: 1974-04-11
Abstract: Monocular reflex camera for endoscopy applications embodies one or more partially transparent prisms (1, 2) in the beam path which have the function of directing a diverted beam to one or more observation eyepieces (3, 4). This enables a number of observers to view the picture at once. Preferably the prisms specified can be slid (7, 6) out of the beam path just before the exposure. The deflected beam path should contain a number of mirrors (5), or again two of the partly transparent prisms can be formed into a single unit. Where a camera with swing mirror is used, the seeker prism (1) is partially transparent so that the admitted pencil beam strikes a second prism or mirror and is thus diverted to the observer eyepiece.

Title: Downhole turbodrill with low and high speed turbines - only part of the mud passing through the high speed turbine
Inventor: IOANNESIAN ROLEN A
IPC: E21B4/02
Filed: 1974-04-18
Abstract: A downhole turbodrill has a tubular housing accommodating low speed and high speed turbines whose rotors are mounted on interconnected coaxial solid and hollow shafts respectively, the arrangement being that all the drilling fluid passes through the low speed turbine but the flow then splits, part of the fluid passing through the high speed turbine and the rest passing through the hollow shaft to a drill bit carried thereby. When the bit is of the hydraulic jetting type utilizing a high pressure drop, it is not necessary to increase the operating pressure of the mud pump. The high speed turbine provides a high torque and also operates as a packing gland.

Title: Floating floor expansion joint batten - has elastic deformation section in shaped rail between relatively movable flanges
Inventor: MAISCH HERMANN
IPC: E04F15/14
Filed: 1974-11-26
Abstract: The expansion joint batten for incorporation in finished floors, comprises two parallel flange components with a shaped strip of elastically deformable material, e.g. foamed plastic or rubber, held between them, extending along the joint gap between adjacent flooring surface faces when in position and connectable to the end faces of the flooring.

Title: Sensitivity switching circuit for car radio - uses control signal supplied to amplifier stage during tuning
Inventor: PROELSS HANS DIPL ING
IPC: H03G3/20
Filed: 1975-04-19
Abstract: The sensitivity switching circuit is used to increase the sensitivity of a car radio during tuning. An HF signal obtained from the oscillator (3) of the receiver circuit is supplied to an identification circuit (7), which converts the HF signal into a control signal, via differentiation of the HF signal with respect to time, during the tuning operation. The control signal is used to control the sensitivity of an amplifier stage (4) of the receiver, via a switching stage (8). The switching stage (8) has a relatively small time constant for the decreasing of the receiver sensitivity, and a relatively high time constant for the increasing of the receiver sensitivity.

Title: Failsafe interlock for inertial seat belt - with blocking solenoid operated by door switch to push pawl into belt ratchet
Inventor: SEIFFERT ULRICH DR ING
IPC: B60R22/41
Filed: 1975-07-03
Abstract: The vehicle seat belts are fitted with an inertial block (4) which prevents the belt from unreeling when a set retardation is reached, or when the vehicle is tipped by more than a set angle. The blocking lever (4) moves a ratchet (6) into the toothed wheel (2, 3) of the sprung reel. The lever is held away from the wheel by an electro-magnet (8) operated by the doro courtesy switch (9) which is on open circuit when the door is closed. The switch prevents the blocking system from operating if the door is opened. This enables rescuers to release passengers from an overturned vehicle simply by loosening the doors.

Title: Arc welding electrode position control - by deviating arc magnetically and measuring the arc length
Inventor: PUSCHNER PETER DR ING
IPC: B23K9/073
Filed: 1975-07-25
Abstract: The position of an electrode holder is adjusted w.r.t. a joint between two workpieces which are to be welded together. At least two characteristic quantities of the arc parameters are derived from the arco burning between the electrode holder and different regions of the sides of the joint. The characteristic quantities are mathematically coordinated and the result is compared with a control value which corresponds to the desired position of the electrode holder, and a control margin, which corresponds to the difference between the result of the calculation and the control value is used to position the electrode holder. The welding arc itself acts as a sensor determining the relative position between the electrode holder and the joint.
