Patent DE-2605320-A1 (DE)
Title: Lock with bolt travel magnifying drive - has levers around lock nut for full locking with one revolution
Inventor: KOETTER HANS
IPC: E05B59/00
Filed: 1976-02-11
Abstract: The lock with horizontally sliding locking bolt has drive has drive for magnifying the lock travel by indirect actuation. The full bolt travel is carried out with single revolution locking movement. This lock is used with metal frame doors. Around the lock nut is arranged a rotating component actuated by a key. The rotating component transmits its rotating movement to a carrier whose centre of rotation is below the nut. The contact is made at a point of engagement which is once again below the point of rotation of the carrier. The carrier transmits its relatively magnified rotating movement to the locking bolt linearly.

Title: Slide projector motor arrest - uses resistive short circuit, pref. lamp which is permanently connected across motor
Inventor: SCHULZE EWALD ING GRAD
IPC: G03B23/02
Filed: 1976-02-28
Abstract: The diapositive projector has a d.c. motor to move its magazine forward and back. A short circuit for the motor ensures that it stops at the exact position required. It does this by absorbing the electromotive force the motor generates when it is switched off. The shor circuit is a resistor connected permanently across the motor, and taking a current of the order of that flowing in the motor armature circuit. The resistor preferably takes the form of a lamp. The method avoids the use of a relay to establish the short circuit.

Title: Transparent bottle inspection system - employs electronic circuit to differentiate between shadows and foreign bodies
Inventor: FAANI SIAMAC
IPC: B07C5/12
Filed: 1977-02-10
Abstract: High speed inspection of bottles used in the food and drink industry is performed using an electronic system to detect opaque foreign bodies. Problems of differentiating between shadows and these bodies are overcome. Bottles (11) on a conveyor (10) are illuminated (13) from behind such that the image is projected onto photosensitive detectors (23). Synchronisation signals are provided by an optical system comprising source (18) and receiver (19). These signals are passed to a digital electronic circuit (24, 26) where rectilinear coordinates of an inspection window are superimposed on the detected image. The data in memories is used selectively per analysis of different physical characteristics of the bottles.

Title: Brush mfg. machine with drilling and plugging units - has sensing pin and control member determining height adjustment of brushes
Inventor: SCHNEKENBURGER EMIL
IPC: A46D3/08
Filed: 1977-10-26
Abstract: The control unit of the height adjustment mechanism detects by a sensing pin (52) the surface of a control brush member (3a) when this surface alters its relative position.

Title: Electronic control for fuel injection in vehicle engine - has output modified during warming up to maintain catalytic reactor performance
Inventor: ISOGAI YOSHIHISA
IPC: F02D41/00
Filed: 1977-11-07
Abstract: The circuit has a signal generator which receives inputs from transducers responding to fuel air ratio, suction pressure, cooling water temp., acceleration and throttle position. A signal corresponding to the speed is obtained from the distributer. The output of the signal generator controls the fuel injection valves in the cylinders. A temp. detector in the catalytic reactor in the exhaust yields a signal which operates a switching circuit. When the reactor temp. is below a preset value a switch stops fuel injection to one cylinder and the output of the signal generator is modified to increase the fuel air ratio in the other cylinders. The inoperative cylinder dilutes the exhaust whilst the others receive the correct mixture for cold running.

Title: Bounce free shutter drive for camera - has pressure linkage to hold shutter against housing and stops
Inventor: SIMON HORST
IPC: G03B9/16

The edges of the shutter elements are shaped to interact with a special stop to provide a retarding force which presses the shutter elements against the stop and against the support housing. The retarding force causes a braking effect without any shutter bounce. No external damping controls are required.

Title: Cutting tool lock for machine tool - has retainer pivotally mounted on carriage which is movable w.r.t. tool socket
Inventor: MARTIN KENNETH R
IPC: B23B31/107
Filed: 1977-12-30
Abstract: The lock assembly includes a carriage which is movable toward and away from the socket. A retaining member is pivotally supported on the carriage. Movement of the carriage toward the socket moves th retaining member from a disengaged position to an engaged position. As the carriage moves toward the socket, the retaining member rotates relative to the carriage from the disengaged position in which it is disposed at an oblique angle to the central axis of the socket to the engaged position. The pivotal movement of the retaining member enables a major component of the force holding the tool in the socket to be transmitted in a direction parallel to the central axis of the tool.

Title: Deep drawing plastic foils - using selvedge guide devices for divergence of strip width by heat
Inventor: KUTZ HERBERT
IPC: B29B13/02
Filed: 1978-01-04
Abstract: A hot moulding system for articles made of plastic foil, esp. by deep drawing, uses a heating device under which the strip is passed. A guiding device is applied to the selvedges by which the divergence between them as a result of the temp. rise is set or controlled as a function of this rise. The tensile forces which arise in the foil under fluctuating working conditions can thus be controlled and reduced. The strip enters the deep drawing machine flat and without crinkles.
