Patent DE-2515641-A1 (DE)
Title: Twin crankshaft motor with pulling type piston or connector rods - has equalising yoke connected to piston rods and push rod
Inventor: STIEVE KONRAD
IPC: F02B75/06
Filed: 1975-04-10
Abstract: A twin crank-shaft motor with pulling piston or connector rods, has an equalising yoke (4) attached below the crankshafts which connects both the piston or connected rods (2) and is attached to the ends of pressure or push rod (3). As a result of the operation of this pulling type piston rod system, the TDC of the motor is passed at a slower velocity, thus allowing a later injection of fuel or a later ignition cycle to occur than in conventional systems.

Title: Hot wire cutter for template for spectacle lens - controlled by lens-accepting frame groove sensor
Inventor: MECKLER HELMUT
IPC: B24B9/14
Filed: 1975-04-24
Abstract: In the production of a spectacle lens template utilising the scanning of the lens opening in the spectacle frame by means of sensing element which control the tool producing the template periphery, the template is cut out from a plastic plate disc by means of a thin incandescent wire, controlled by a pointed senser scanning the base of the groove of the lens opening of the frame. Advantageously, the incandescent wire is pivoted into and out of the vertical plans of the pointed senser, before the start and after the end of the sensing respectively. Enables a high precision template to be produced for a spectacle lens in accordance with the contour of the bottom of the groove in the lens opening of the spectacle frame, using an apparatus of simple and cheap construction which can follow the profile of the groove despite variations in the depth of this.

Title: Oxidn. protective compsn. pref. used to deoxidise drinks - and contg. glucose oxidase and catalase, D-glucose and inert adsorbent
Inventor: BAERWALD GUENTER PROF DR ING
IPC: A23L3/3571
Filed: 1975-05-09
Abstract: Compsn. protecting against oxidn. contains an enzyme mixt. of glucose oxidase and catalase together with a solids mixt. of D-glucose and an inert adsorbent. Use of compsn. to remove O2 from drinks, e.g. fruit juices, soft drinks, lemonade, wine and beer, is claimed. An O2 - bonding complex of enzyme and D-glucose is formed quickly. Treated drinks have a longer physico-chemical and biological stability and maintains their original smell and taste. In foam-forming drinks, foam consistency is improved and bitter principle content is reduced only slightly on longer keeping after bottling.

Title: Temperature stabiliser for optical receiver - alters bias on transducer or amplifier to give required output amplitude
Inventor: RUSSER PETER DR ING
IPC: H04B10/69
Filed: 1975-07-02
Abstract: The temperature stabiliser is used for an optical receiver (1) in an optical data transmission system. It produces pulses of constant amplitude according to the incident light irrespective of fluctuations in ambient temperature. The output signals of the receiver are used to construct a voltage that serves as a measure of the amplitude of the receiver output signal. This voltage is compared with a reference voltage. When there is a different between the two, the bias voltage applied to the optical transducer and/or the gain of the circuitry following the transducer is altered in such a way that the receiver output amplitude has the required magnitude.

Title: Switching system responsive to small mechanical or magnetic force - has two multipole magnets on switch shaft facing moving armature
Inventor: LUEHN OSKAR
IPC: H01H36/00
Filed: 1975-10-01
Abstract: The switching system is intended for level or temperature control. It carries magnets (1, 2) on the shaft (3), which are provided with several poles on their faces. The magnets are mounted opposite a moving armature (4) with a magnet (5) so that the slightest movement of the magnets results in a pole change, resulting in attraction or repulsion of the armature magnet. After this step follows a snap-action switching movement, while the switching armature (4) is magnetically locked in each switching position. Preferably the magnet of the switching armature does not generate any effective torque on the magnets mounted on the shaft so that only a slight actuating force is required for effective switching.

Title: Automatic control for railway system - with spacing and speed of trains monitored by phase shift and amplitude of control signals
Inventor: ANGSTMANN RAIMUND DIPL PHYS DR
IPC: B60L3/00
Filed: 1976-02-27
Abstract: The high density railway system has each train fitted with a transmitter/receiver for control signals so that each train can determine the speed and spacing of the leading train. The onboard controls then adjust the speed so that a minimum set spacing can be achieved without danger of collision. The signals are transmitted by and received from a conductor rail with a set damping per length. The signals are transmitted at amplitudes and phase corresponding to the speed. The receiver can then determine the actual speed and spacing of the train in front from monitoring the amplitude and phase of the received signal. A simple circuit translates the received signal into a square toothed signal for simple shift measurement.

Title: Zoom control for small camera - with sprung returns on zoom, distance and friction holds and hand control over rapid setting device
Inventor: WINKLER FRIEDRICH
IPC: G03B3/00
Filed: 1976-03-17
Abstract: The zoom and distance controls of the small camera operate on spring loaded setting tags (202, 203) which are arranged to move the controls into a mean setting. The controls are held in their settings by a brake (204) which is slightly stronger than the return springs to allow simple manual setting. The hand control (207) overcomes the brake force to provide a rapid setting control with one hand. The system is ideal for a small hand held cine or still camera. The hand control is integral with a slit and symmetrical inclined surfaces on either side of the central studs of the setting tags.

Title: Solar water heater - uses collection panel insulated around the edges and with internal air circulation
Inventor: SINGER KURT DIPL ING
IPC: F24D11/00
Filed: 1976-06-24
Abstract: Solar heating of water uses an absorber plate which has several transparent plates above it facing the sum with spaces between them. they are thermally insulated from the surroundings around the edge and on the back. The plates and the absorber being spaced apart from each other, form a series of flow passages. Air or other gas is blown through these by means of >=1 fan and recirculated. In its coolest state, the air passes through the outer passage. Here it is warmed and then passed over the absorber plate. Built into this recirculating system are >=2 heat exchangers, one connected to the cooler zone and the other with the warmer. The air is circulated round these and then into the cooler passage under the outer plate and back over the absorber. Heat losses are reduced. Short sunshine periods and low radiation intensities are well utilised because of short inertia times. Frost sensitivity is avoided.
