Title: Manual typewriter with facility for automatic key cycle - uses stored spring energy for type actuation and includes LCD display
Inventor: HEYMANN ANDREAS
IPC: B41J3/46
Filed: 1980-05-08
Abstract: A manual typewriter is adapted to provide a uniformity of impact force by using energy stored in spring compression that is charged when a carriage return is made. The stored energy is sufficient for both carriage movement and for operating the type mechanism. The system is designed such that operation of a specific character results in display of that character on an LCD display and simultaneously causes printing of the previous character. When the key is operated a release mechanism allows an impact sufficient for printing to occur. By arranging for the character to be displayed ahead of printing, a correction facility can be incorporated. The machine does not require a mains or battery supply and the display can be operated off solar cells.

Title: Shooter head for foundry sand moulding machine - where compressed air is driven both axially and radially onto sand
Inventor: PETERLE GUIDO
IPC: B22C15/24
Filed: 1980-05-21
Abstract: Compressed air is fed into a cylindrical sand container to drive the sand either into a moulding box or a filling frame on the machine. Most of the air is driven axially into the head, but a small amt. of air is driven radially and simultaneously into the container. The pref. head consists of a block contg. two ring chambers fed with compressed air; one chamber is fed with air to drive a ring piston downwards so that air in the other chamber can flow both axially and radially into the container. Alternatively, the piston may be driven hydraulically. Rapid sand shooting without forming defects in the moulds.

Title: Control switch for explosion-proof housing - has switch handle and shaft axially movable against spring force with control discs on shaft inside housing
Inventor: TETZLAF GERD
IPC: H01H19/62
Filed: 1980-05-29
Abstract: The control switch is particularly intended for mining application and has a pressure-tight housing for simultaneous switching of naturally secured and insecure circuits. The switch has a switching handle, which can be locked in individual switching positions, affecting over a switching shaft microswitches inside the housing and round the switching shaft. The handle (19) and the switching shaft (21) are axially slidably mounted against a spring (26) force. Control discs (12) inside the housing are allocated to the shaft and rotatable about the shaft axis.

Title: Fish filleting machine - with prescribed sequence of ventral and dorsal cuts for minimum manual trimming
Inventor: HARTMANN FRANZ
IPC: A22C25/16
Filed: 1980-10-25
Abstract: Headed fish are filleted by a pair of ventral filleting cutters to clear the ventral fin rays up to the backbone and by rib cuts to clear the vertebral extensions. The strip of fishbones is severed and a pair of dorsal filleting cuts clears ththe dorsal fin rays. The fillets are finally freed from the spinal structure by two parting cuts to intersect the dorsal filleting cuts. The filleting machine consists of a pair of ventral filleting cutters (1), followed by the inclined rib cutters (2). The vertebral extensions are severed by the cutters (3) and the dorsal filleting cutters (4) clear the dorsal fin rays. Two fleshy fishbone cutters (5) which face each other in the same plane sever the ventral flaps over the fleshy fishbones, and the fillets are freed from the spinal structure by the parting cutters (6). A fish is now held in the optimum position throughout the operations, with the dorsal fins always kept in line so that any subsequent manual trimming is kept to a minimum.
Patent DE-3045571-A1 (DE)
Inventor: GANGUILLET CLAUDE
IPC: G02F1/15
Filed: 1980-11-28
Abstract: An electrochromic display cell comprises a frame interposed between an ionic conductor and an annular soldered zone sealing a cover of the cell to a substrate of the cell. The frame is squeezed between the cover and the substrate to tightly separate the ionic conductor and the solder, preventing any reaction therebetween. In a preferred embodiment, the frame is made of a thermofusible material. It partially melts during the sealing of the cell, adhering thus very tightly to the cover and to the substrate.

Title: Hanging rail for hanging cabinets
Inventor: GRASS ALFRED ING
IPC: A47B95/00
Filed: 1981-02-09
Abstract: The invention relates to a hanging rail for hanging cabinets. The object of the invention is to develop the slide further such that it is held captively in the groove of the hanging rail. The achievement of the object is characterised in that, for securing the slide in its position and against displacement on the hanging rail, projections are arranged in the region of the bent sections of said hanging rail, which projections engage at least partially over the slide in the direction towards the rear wall of the furniture body. An essential feature of the invention is thus that there are projections either on the hanging rail or on the slide serving for securing the slide in its position and against displacement. Despite these holding means, the slide continues to be adjustable in the direction of the longitudinal axis of the hanging rail.

Title: Measuring wheel set for rail vehicles
Inventor: BERG HERMANN
IPC: G01G19/12
Filed: 1981-04-10
Abstract: The invention relates to a measuring wheel set by means of which it is possible in the case of rail vehicles to measure the horizontal forces on the wheel sets without influencing the wheel support point in driving mode. Eight sensors each are arranged on three measuring cross-sections (I, II, and III). Two sensors each, which are offset by 180 DEG , form an arm of a Wheatstone measuring bridge. The measuring voltage across this bridge is a measure of the tensile or compressive stress  sigma  occuring. Horizontal forces (Y1 and Y2) can then be determined from the measured tensile or compressive stresses. <IMAGE>

Title: Liquid crystal display device (unit) and the use of liquid crystal materials in such a device
Inventor: HAMPEL BRUNO DR RER NAT
IPC: G02F1/139
Filed: 1981-08-05
Abstract: A liquid crystal display device is to be constructed so as to enable quick exchange of information in conjunction with a large quantity of information independently of the ambient temperature and with as little additional expenditure as possible on circuitry for driving the display device. For this purpose, a nematic liquid crystal material - preferably having a twisted phase and, if appropriate, with the addition of dichroitic colorants (dyes) - is selected which when driving its pairs of electrode groups at a frequency above a material-specific transition frequency value exhibits a dielectric anisotropy of different sign than in the case of driving below that transition frequency value, accompanied by displacement of the transition frequency value as a function of ambient temperature. As a result, driving can be performed using frequencies and amplitudes which are fixed in advance independently of the ambient temperature, because increasing the absolute value of the dielectric anisotropy in conjunction with lower ambient temperatures produces higher restoring forces. Application, for example, in large display panels installed in the open air and thus exposed to large fluctuations in ambient temperature, for example for traffic control or in sports stadia.
