Patent DE-2615932-A1 (DE)
Title: Continuous development tank for small runs - uses min. reagent quantity with partly immersed film drive elements along container length
Inventor: KLEIN EDMUND
IPC: G03D3/13
Filed: 1976-04-10
Abstract: The continuous operatin developing and processing machine for photographic negative or positive materials, has a reagent bath (1) and the necessary transport mechanism for the material under treatment in which the liquid in the container is only shallow, and the transport mechanism is partly submerged along the length of the container. The transport may be effected by an endless band (8) with pressure rollers, or by a cylindrical drum. The arrangement permits the use of a minimum quantity of reagent and is particularly suitable when the equipment is only needed for processing small runs at relatively long intervals.

Title: Pre-set piezo electric igniter instrument - has spring of operating button and impact hammer acting in opposite directions
Inventor: SOEHNCHEN ERNST
IPC: F23Q3/00
Filed: 1976-05-15
Abstract: The instrument has a cylindrical housing with an inner shell and outer shell with two open ends. In the vicinity of one end the piezoelement is fitted to an anvil by a pin. In the upper part of the housing, a hammer is slidingly fitted with a spring loading it towards a striking pin. The housing has an extended part serving as a stopping edge for the turned-over edges of an operating button which is loaded by a spring in direction away from the piezoelement. Inside the button stem of the hammer is slidingly fitted. The stem also carries a rigidly fitted expanding spring with legs resting on the inner part of extension. A trigger bushing is resting with its bottom edge on the outer surface of the legs. for operation the button is pressed downwards compressing spring. At the end of the compression the trigger bushing is moved downwards with its edges narrowing the diametric distance between the legs until they clear the internal shoulder of an extension nad the hammer is ejected by the spring force and strikes the pin producing a piezoelectric energy of invariable intensity. After the impact the hammer is returned to its basic position by a spring.

Within the cavity, the cartridge is pref. located centrally between two spring-loaded buffer plates; the cartridge core can be a flexible perforated strip, wire or plastic mesh material, a helical coil etc. A hair styling brush carrying its own supply of hair treatment agent for conditioning or hydrating the hair, usually by virtue of heat supplied by a hand-held hair dryer, although an electric heating element can be fitted in the compound chamber.
Patent DE-2634408-A1 (DE)
Title: Electronic thermometer with digital read=out - has voltage to frequency converter and timer for temp. and time interval display
Inventor: TURNER ROBERT
IPC: G01K7/24
Filed: 1976-07-30
Abstract: The miniature electronic thermometer with digital readout comprises a measuring probe (12) whose output is connected to a precision bridge driven from a stable reference source. The bridge output passes through a time-extrapolation circuit and to an integrator. The integrator operates in conjunction with a generator which produces an output of constant pulse amplitude and duration. The circuit operates as a voltage-frequency converter whose output frequency varies in sympathy with the temperature variation of the probe (14). A counter (16) comprising a decoder which counts the pulse output of the generator over a predetermined time interval, provides a digital display of the temperature. A digital logic controller allows the display to show both time intervals and measured temperature.
Patent DE-2636036-A1 (DE)
Title: Vehicle seat-belt take up mechanism attachment - operates limited off-coiling movement of seat-belt by instant action of spring pressure
Inventor: WOLFF HANS-DIETRICH
IPC: B60R22/44
Filed: 1976-08-11
Abstract: The automatic take up mechanism allows a limited off coiling of the belt to create a slack necessary for comfortable wear, with subsequent blocking of the mechanism in readines for possible emergency situations. Additionally the mechanism must allow a further off coiling even after the blocked condition, when, for instance the wearer decides to lean forward with his seat belt already strapped. The design uses the instant action of a sping mechanism which produces the required slack following a sudden jerking movement with subsequent renewed blocked condition which persists over an unlimited period.
Patent DE-2636770-A1 (DE)
Title: Measured valve indicator on balance - uses visual display window in front of moving strip with numbers
Inventor: RIET ALOYSIUS JOHANNES VAN
IPC: G01G23/34
Filed: 1976-08-14
Abstract: A device is used for indication of measured values determined by a balance. It is designed for simple, compact, and reliable construction whilst ensuring exact, unambiguous readings for all scale regions. The indicator has a visual display window with numerical indication of the measured value (26), the numbers moving past the window as a reading changes. A parallel indication is derived from a control track moving next to the numerical indicator, e.g. a track with alternating dark and light fields (50). An optical detector senses the transition between two alternate fields to give an unequivocal measure of a digit changeover on the numerical indicator. The numerical indicator is read w.r.t. to adjustable scale markers.

Title: Transverse cutting roller for web material - has constant speed drive and fly wheel to decelerate and accelerate roller
IPC: B26D5/08
Filed: 1976-12-21
Abstract: The transverse cutter for web material has a cutting roller which is so powered by a constant speed drive via a transmission that during each rotation the roller is once accelerated and once decelerated. This is achieved by interposing between drive and transmission a differential gear with a cam-controlled flywheel mass (16). This gearing accelerates the mass when the roller is decelerated and vice-versa so that the sum of the kinetic energies of transmission and roller on the one hand and of the differential gearing on the other hand remain constant. The gearing has a fixed cam disc (18) which makes contact with a level (13, 14, 15) swivably mounted in the mass (16). The lever engages with a pinion (12) in a gear wheel or segment (11) which is positioned on the drive shaft (10).

Title: Counterbalancing weights fabrication method - involves shrinking plastics sleeve on to threadless nut to form self-tapping cover
Inventor: ORTMANN FRIEDHELM
IPC: G01D11/08
Filed: 1977-06-18
Abstract: Counterbalancing weights are formed from six-sided nuts (1) which are held in a shrinkable sleeve (2) with their axes transverse to the axis of the sleeve. The holes in the nuts do not have the customary thread, but are straight-sided. The nuts are placed so that adjacent faces abut one another and the sleeve is shrunk to reveal the position of the remaining four face, and to cover the axial holes. They are then separated with a razor blade. In use the sleeve is pierced with the pointed end (4a) of a threaded rod (4). By a rotary action, the nuts are mounted on the rod, the sleeve material forming a self-tapping thread. The friction between the sleeve and the rod is great enough to lock the nuts in position.
