Title: Switching circuit for vehicle flashing indicators - has central permanent impulse generator with current control relay operation
Inventor: PROHASKA HANS
IPC: B60Q1/38
Filed: 1973-11-17
Abstract: The current control relay is connected in series with the collector-emitter layer of a switching transistor and the input of the vehicle direction indicator switch. The basic circuit of the transistor is adjusted by a first central switching contact, switching a control lamp in and out via the collector-emitter layer of a second switching transistor. The basic circuit of this transistor is connected via a change over switch of the current control relay in the working position to the first central switching contact in the off position. The two switching contacts have different impulse sequences but similar periodic lengths. There is a by pass resistor for the first switching transistor. The latter is a PNP transistor with the emitter connected to the applied potential and the collector to the current control relay.

Title: Multicolour enamel decoration rig - for cooking vessels with four different colour stations around intermittently operated turntable
Inventor: BEHNISCH ROLAND
IPC: C23D5/06
Filed: 1974-02-15
Abstract: Cooking vessels receive a decorative enamel by applying to the wet unfired enamel layer an enamel powder, mixed with a bonding agent which softens during drying. The vessels are fired after drying. Prior to drying and firing, several enamel or other decorative powders, mixed with the bonding agent, are applied in turn to the wet unfired basic enamel layer. The powders which differ from each other by their colour or structure are applied from hoppers and stencils arranged in several stations around a turntable carrying the vessels. This is a rapid and inexpensive method of applying multicoloured decorations on curved surfaces.
Patent DE-2407522-A1 (DE)
Title: Linear motor magnetic hovertrain - with sprung motor section fitted with air gap correcting electromagnets
Inventor: WEIDA MARTIN DIPL ING
IPC: B60L13/03
Filed: 1974-02-16
Abstract: The main motor part of the linear motor is connected to the rest of the vehicle by springs which tend to pull the motor away from the fixed rail and hence increase the air-gap. Small electromagnets on each side of the motor, between the sprung and unsprung sections, act in opposition to the springs and serve to correct the airgap. The electromagnets operate with a minimum of lag and enable the servo system to maintain the airgap w.r.t. the construction tolerances. The system operates at maximum efficiency with the optimum airgap.
Patent DE-2407600-A1 (DE)
Title: Automatic single lens reflex camera - uses with impulses controlling aperture setting for exposure meter, with no power loss
Inventor: STRAUSS KARL-PETER DIPL ING
IPC: G03B7/085
Filed: 1974-02-16
Abstract: The camera uses a through-the-lens exposure control with the aperture setting system driven by an impulse circuit, with the frequency of the impulses much shorter than the response of the shutter. The pulses are processed and fed to the shutter setting mechanism as either positive or negative pulses depending on whether the shutter has to be opened or closed further. When the actual apertures setting is reached the pulses stop and thereby reduce the power drain n the camera battery to a minimum. The system is superior to conventional systems in which the pulses are continuous, and are modulated to alter the aperture setting.

Title: Rapid cooling of sterilisers - maintaining pressure equilibrium in the sterilised containers
Inventor: NEISS OSKAR ING GRAD
IPC: A61L2/24
Filed: 1974-10-02
Abstract: In anappts. for the rapid cooling after sterilisation of sterilised matl. present in sealed containers under the pressure and temp. of the expanded water vapour, while maintaining the operating pressure which at the start of cooling comprises the partial pressure of the expanded water vapour and the superimposed partial pressure of a non-condensible gas, by using a cooling medium, (i) the pressure difference arising from the provision of two pressure pick-ups oppositely affected, one of these being subjected to the autoclave operating pressure and the other to the pre-selected, but lower set value derived from a different pressure source, produces an alternating change of posn. of the two coupled pressure pick-ups with a max. and a min., and (ii) delay-free control pulses are released for supplying a cooling medium when a max. within the pre-set limits is reached in the autoclave and for supplying a pressure-compensating agent on reaching the minimum therein so that the operating pressure over the whole cooling process is maintained by maintaining the pressure difference. Permits very rapid cooling of the steriliser contents using air as the non-condensible gas for pressure compensation.
