Patent DE-2738462-A1 (DE)
Title: Roller crusher with impact ledge - has two counter-rotating rollers and roof-shaped material-distributing strip
Inventor: FRITZ ULRICH
IPC: B02C4/12
Filed: 1977-08-26
Abstract: The crusher is suitable for materials with relatively low strength such as coal. The material is fed into the crusher through a hopper with a guide element of roof shape which distributes the material evenly to the two counter-rotating rollers with beater tools. The disintegration of the material is effected partly by the crusher housing walls with smooth, or ribbed surface and partly by the fixed or adjustable impact ledge against which the coal pieces are hurled by the rotating beater tools. The crushed material drops on the conveyor belt to be transported away. The machine can be fitted with a chassis to make it mobile.

Title: Battery motor for outdoor charcoal grill - is used to drive both spit and blower
Inventor: HOTZY JOHANN
IPC: A47J37/04
Filed: 1977-09-12
Abstract: The design utilises the battery driven motor (1, 2, 3, 4) to drive either the spit of the outdoor charcoal grill or a blower for assisting the charcoal fire. The spit is driven from the output spindle of a reduction gear mounted on the grill frame. The spit drive spindle (18) pushes into the output spindle (17). Alternatively the fan, or blower, spindle (25) can be pushed into the direct drive (12) on the end of the motor shaft. As both drives are not required simultaneously good use is made of the motor.

Title: Gun holster made of plastics with metal or plastics closure - ensuring quick-draw action owing to absence of deformation by weather conditions
Inventor: DRIES HEINZ
IPC: F41C33/02
Filed: 1977-09-14
Abstract: Gun holster, made of a plastics material, has a novel opening and closing mechanism. The holster case is of dimensionally stable plastics to which metal or plastics cover is attached which opens atomatically when the gun is drawn.

Patent DE-2832924-A1 (DE)
Inventor: WIEDENFELD HELMUT
IPC: D02H13/20
Filed: 1978-07-27
Abstract: In a pair of part combs of an expanding comb of articulated design, the comb-needle set (14) of the first part comb (11) projects beyond the axis of rotation of the rotary joint (18) by at least one comb-needle division. The first comb needle (29) of the second part comb (12) is a maximum of one comb-needle division further away from the axis of rotation of the rotary joint (18) than the last comb needle (30) of the first part comb (11). As a result, a thread set having a uniform thread spacing is obtained in all the angular positions of the expanding comb, even when the comb-needle spacing is very narrow. <IMAGE>

Title: Overpressure fluid engine cooling system monitor - compares temp. and pressure sensor signals and warns of threshold difference
Inventor: HIESTERMANN KURT ING GRAD
IPC: F01P11/16
Filed: 1979-03-17
Abstract: A monitor for an overpressure fluid cooling system, esp. for combustion engines, has a cooling fluid temp. sensor providing a corresp. signal to an analyser. The monitor reacts to cooling system leaks since the overpressure fluid can boil at much lower temp. than when the system is sealed. A second sensor provides the analyser with a signal corresp. to cooling system fluid pressure. The analyser produces an output signal when the difference between the two input signals reaches a defined min. value. The signals are compared in a differential amplifier comparison stage driving a relay switching element. Each signal has a corresp. indicator needle. One needle covers the other, which has a coaxial axle shaft until the min. difference is exceeded.

Title: Optically projected picture scanner - has photoconductors discharged by light beam and recharged by gas discharge
Inventor: FISCHER DIETER DIPL PHYS DR
IPC: H04N3/10
Filed: 1979-03-19
Abstract: Flat shape and small size of scanner of optically projected images as well as simplified control logic are ensured by the unit featuring a photoconductor charged by gas discharges. The discharge of the scanned points is proportional to the intensity of light beam impinging the spot while the gas discharges ensure recharging. TV images are picked up by simultaneous scan of all points of the image line while the individual lines are scanned in synchronism with the horizontal deflection frequency. The transparent plate (I) of each element carries a similar electrode (2) coated with photoconductive layer (3). The apertured mask (7) separates insulator plate (4) holding electrode (5) and resistance layer (6), the size of openings in the mask determining the gas discharge volume (10). The signal is derived from resistor (II) connected to electrode (2) while the scan lines and columns are formed by electrodes (2, 5).
