Patent DE-1941823-A1 (DE)
Title: Comparative weighing machine eg butter - water content
Inventor: BOSCH LUDWIG
IPC: G01G19/22
Filed: 1969-08-16
Abstract: Comparative weighing machine e.g. butter water content. For rapid calibration and setting, the needle pivot and the scale engraved direct in percentages, may be moved laterally on a sliding carriage, by a lead screw and adjuster knob, relative to the actuating lever from the beam of the balance causing the pointer to deflect. From the pointer shaft, diametrically opposite to the pointer, a pair of round parallel rods extend radially and a side pin on the above actuator lever passes between them. The basic balance system used is of conventional type with spring loaded tare weight compensation for the sample containers and eddy current beam damping.

Title: Resilient rubber stud with hollow tip - mfd. in two part mould with fixed core forming hollow
Inventor: FISCHER WERNER
IPC: B29D22/02

Title: Double-sided games board for bingo - has press-in discs with numbers or symbols
Inventor: STUBBMANN ALBERT
IPC: A63F3/06
Filed: 1973-08-15
Abstract: The game board consists of two boards placed back to back and joined round the outside with a space between them in the middle. These boards have corresponding rows of holes and bushes pass from the holes in one board to those in the other. Into these bushes are fitted discs with a number or symbol on each side. The thickness of the discs is less than the length of the bushes so that when a disc is pressed down it ceases to be level with the surface of the upper board, but becomes level with the surface of the lower board. Thus both sides of the games board can be used, and the pressed-in discs remain in place and can still be read.
Patent DE-2343099-A1 (DE)
Title: Dry offset printer inking unit - all rollers form with their frame an exchangeable cassette
Inventor: SCHULZ JUERGEN
IPC: B41F31/15
Filed: 1973-08-27
Abstract: The unit is centred around the transfer roller with ink carrying rollers, distributors and inkers set in a planetary manner between two side plates. These are interconnected by four rods and the ink is supplied by a vibrator oscillating between ductor roller set in the ink fountain and roller. The housing of the distributors feature air cylinders controlling their axial displacement with air delivered through a channel in the side plates. The location of the unit on the machine frame is facilitated by spigots, and the removal of one unit can be replaced by a spare one. This allows washing outside the printing press with mechanized handling and thus reduces the idling period of the press.

Title: Automatic exposure control for camera - uses light value capacitor storage with integrated circuit sequence control
Inventor: HUMMEL HERBERT
IPC: G03B19/12
Filed: 1973-09-21
Abstract: The initial depression of the camera exposure release operates a switch mechanism which starts an electronic timing circuit whilst the reflex mirror moves out of the objective light path. During the timed interval, the photodiode or photo transistor charges a storage capacitor. At the end of the charging interval the timing circuit initiates the start of the exposure, disconnects the photocell and triggers an integrating circuit made ready by the switch mechanism. This circuit has a high input impedance and feeds its output to a discriminator circuit. When a signal value corresponding to preset and metered factors is reached, the shutter closing signal is generated to terminate the exposure.
