Title: Telephone kiosk door opening stop mechanism - has stop ledge for bounding recess for radial lug on pivot pin
Inventor: QUANTE HERMANN
IPC: E05D11/06
Filed: 1979-06-13
Abstract: Resiliently yielding limitation of opening is provided for doors rotatably mounted in a fixed frame by two pivot pins rigidly connected to the door wing, esp. in telephone kiosks. One of the bearings, at least, incorporates a torsionally elastic accommodating unit held so as not to rotate. The pivot pin housed in this has a radial protrusion countered by a stop ledge on the accommodating unit. The ledge bounds the end of a cutout for the protrusion determining the door wing free turning angle.

Title: Machine for making easter eggs - with revolving shafts in spider-arms for carrying hinged moulds (BR 22.4.81)
Inventor: IVALDI GIUSEPPINA
IPC: A23G1/21
Filed: 1980-02-16
Abstract: A machine to produce thin-wall hollow prods. of chocolate, e.g. Easter eggs, consists of a step-by-step moving conveyor on which two-part moulds are moved from a filler station to a frame in which a spider with several radial arms picks up the closed moulds.

Title: Automatic differential temp. control for room heating - uses movement sensors to raise maintained room temp. level when room is in use
Inventor: HIRCHE MANFRED
IPC: G05D23/19
Filed: 1980-03-24
Abstract: The control automatically detects the presence of someone within the room to switch the maintained room temp. to a higher value than the temp. value maintained when the room is not in use. These two temp. values may be set by a thermostat allowing independent selection of two temps. The presence of an occupant within the room is detected by radar, IR or ultrasonic movement detectors and is used to control a relay allowing a fan convector etc. to be energised for a sufficient interval to provide the increase in room temp. required. Subsequent movement causes the relay to be maintained in the energised state. Pref. the room is maintained at a temp. of 18 deg.C. when not in use and fan convectors energised when movement is detected allow its temp. to be increased to 22 deg.C. within about five minutes.

Title: Image data transceiver for ground covered by aircraft - feeds image sensor data to image memory via A=D converter, recalled by position-dependent, intermediate scanning
Inventor: HORNFELD WILLI DIPL PHYS
IPC: H04N7/00
Filed: 1980-05-09
Abstract: The transceiver has an image sensor in an aircraft, whose output data are transmitted to a stationary device via a data reduction stage and a data transmitter. The output data of the image sensor are supplied to an image memory via an a-d converter. From the memory they are recalled by a local intermediate scanning of low image rate and supplied to the data transmitter via differential pulse code modulator (4). The image sensor, the memory, and the modulator are in two-way functional connection with a controlling microprocessor via a data bus. The image rate of the intermediate scanning is preferably adjusted to such low value that two subsequent images overlap by 55%. The differential pulse code modulator may trigger 40% of the upper image region from the supplied image data and 10% of each image edge at one bit per image point. The residue of the image is triggered alternately at 1 and 2 bit per image point.

Title: Absorption heat pump for hot water supply - passes driver exhaust gases through hot water heat exchanger before mixing with air
Inventor: MECKEL BERND DIPL PHYS
IPC: F25B30/04
Filed: 1980-05-16
Abstract: The heat pump for providing a hot water supply has a drive (1) containing a heat exchanger coil (3) in its exhaust outlet, and conveys a refrigerant in gas form to a condenser (2) obtaining heat for the circulating hot water. The refrigerant is passed through a heat exchanger (4), an evaporator (5) after passing through an expansion valve (6).

Title: Door latch lock bolting mechanism - has bolt turning in lock case above latch
Inventor: PRUSKO HERBERT
IPC: E05B13/08
Filed: 1980-06-10
Abstract: The door lock with a closing latch has a bolting device (14), above the latch (4) rotatably mounted in the lock case. The body of the bolt can incorporate two circular collars, a trapezoidal lug, and an aperture aligned parallel to its longitudinal axis. The latch can have a recess, shaped correspondingly to the lug, on the top of its shaft (8). The bolting device aperture may be engaged by the pin of a handle rotatably mounted in the doorplate. This provides a latch catch with the bolting device preventing unintentional closing of doors, and also preventing the latch from being pushed into the lock case when the door is closed, thus enhancing security against break-in.

Title: Cine film copying equipment - uses servo motor brakes on film reels to control film tension
Inventor: KIENING HANS
IPC: G03B27/10
Filed: 1980-07-09
Abstract: Cine film copying equipment has separate feeds for the master film (16) and the copy (18), with the separate supply (15,17) and take-up reels (19,20) driven by servo motors. The servo motors on the supply reels act as controlled brakes. Film loop sensors (21,27,24,30) are fitted each side of the exposure position to provide control signals for the brake action, and maintain the film tension. The tension is such that the film is pulled to one side of the sprocket wheel teeth, with the single sprocket wheel controlling the rate of film feed. A pressure drive (32) presses the two films together for a contact printing action, with minimal slip between the films.

Title: Self-advancing mine roof support - has three roof support elements spaced apart along abutment in pivotal manner adjacent work face
Inventor: WELZEL JOSEF
IPC: E21D23/08
Filed: 1980-07-26
Abstract: A beam-like abutment (12) of a self-advancing mine roof support is disposed adjacent and parallel to a work face. Three roof support elements (A,B,C) are spaced apart along the abutment and are pivoted to the abutment.

Title: AM transmitter with carrier control - using residual carrier value with characteristic value as function of lever for control
Inventor: SCHNEIDER BERND DIPL ING
IPC: H03C1/62
Filed: 1980-10-03
Abstract: The amplitude modulated transmitter has a carrier control using the residual carrier value. The value of the carrier is only changed to a given minimum carrier value in the same sense as the level of the modulation signal. This effects an energy saving and improves the characteristics of the transmitter. The carrier is controlled using a characteristic of the carrier value as a function of the level. The characteristic varies from a straight line through the two points where the carrier residual value-level is zero and the maximum carrier value- maximum permissible level. The variation is such that a smaller value is allocated in the range of the most frequently occuring level.
