Title: Cattle stall yoke arm - has inverted U-shape main frame with one arm supporting, guiding and locking pivotal operating arm
IPC: A01K1/062
Filed: 1976-05-19
Abstract: A cattle stall yoke frame has an inverted U-shape main frame of two arms joined by a crosspiece, and an operating arm hinged on one of the main frame arms. When the animal puts its head through the wider upper part of the frame, its neck presses against and moves the lower part of the operating outwards, which results in the upper part of the arm moving inwards, securing the animal in the frame. The upper part of the operating arm moves in a guide attached to the upper frame and having several stops against which the upper part of the arm operates. The animal is thus automatically secured. The frame is suspended by a chain from a cross tube joining two vertical side tubes to which the arms are attached by a chain. chains also attach the bottom of the two arms to the floor.

Title: Identification device for telephone - transmits caller number to called party as well as indicating number dialled
Inventor: SCHANTZ HERMANN
IPC: H04M1/56
Filed: 1976-08-10
Abstract: The identification device, for a telephone, has a display for the area code and for the number within the area and a code generator for own telephone number and its area code. The caller dials the number wanted, which is then displayed on his display. When the called party lifts his receiver the caller can only make a voice connection by depressing a release key. This key causes the code generator to transmit his own telephone number to the called party where it displayed. The caller is thus identified. The display is erased when the called party replaces his handset.

Patent DE-2710316-A1 (DE)
Title: Filter unit for exhaust air - having coarse element followed by fine web on continuous belt
Inventor: WAELTI ROBERT
IPC: B01D46/00
Filed: 1977-03-09
Abstract: The coarse element is flat and the unit operates dry. The depression in the exhaust chamber is measured and when this exceeds a preset value, a winding mechanism rolls a fresh section of webbing across the filter opening. The filter is mounted perpendicular to the direction of flow of the air. The web covers the whole of the air passage and is unrolled from one side and the dirty web rolled up on the other. The drive mechanism for these rollers is linked in with the pressure detector in the outlet chamber. This can have an alarm. The coarse element is exchangeable and is mounted in the inlet section. Dry filters suffer from rapid blockage problems while wet filters create a second effluent problem. The filter described has neither of these disadvantages, giving clean exhaust continuously and automatically.
Patent DE-2713002-A1 (DE)
Title: Superconductor for high power AC transmission - has spacers separating sections of overlapping superconductors in coaxial system
Inventor: GERLACH HORST DIPL ING
IPC: H01B12/12
Filed: 1977-03-24
Abstract: Super-conducting cable is for high power transmission of a.c. along certain stretches. The cable is resistant to excess current produced by a fault situation and at the same time acts as a protection against excess current for other components in the plant. It consists of concentrically arranged layers of conductors separated by insulating layers. The conductors are separated by spacers (4) with overlapping sections (10, 20) of two normal or super-conducting conductors (1, 2). The sections (20) of a conductor (2) are rigidly linked to another super-conductor section (3) via a ring-flange (22). The capacitive reactance of the conductors divided into sections is less than the resistance of the super-conductors in normal conducting conditions. However, the value of the capacitive inductance at excess current conditions is such as to limit the current to approximately rated value.

Title: Centrally actuated motor vehicle locking system - has energy storage disc energised by movements of vehicle door or flap
Inventor: SEIFERT GERD W DR ING
IPC: E05B77/48

Title: Loaf from different kinds of dough - has bottom layer of specifically heavier whole meal than upper mixed layer
Inventor: DRECHSLER HORST
IPC: A21D13/00
Filed: 1978-02-22
Abstract: Bread formed from different kinds of dough has >=2 layers one upon the other, and is baked in a tin; the underlayer being from a dough which is specifically heavier than the dough of the upper layer or layers. The expensive practice of cutting and packing slices of wholemeal bread with slices of bright mixed bread, so that there is an interchange of aroma and taste is superceded. Instead the interchange takes place during baking. The method prevents the excessive prodn. of gas which otherwise separates the layers, and the various layers are attached securely together.

Title: Suspended ceiling with grid frame - has groove and threaded rod system permitting opening and closing filling panels from below
Inventor: RITTER KARL
IPC: E04B9/06
Filed: 1978-03-07
Abstract: The lattice frame hung from the main ceiling has spaces filled with tray shaped panels, pressed by springs against a horizontal frame member flange. They can be removed upwards against locking spring force.
