Title: Latching device for coaxial cable plug connector - has guide bush with slot and socket with bent clamping spring held by nut
Inventor: FUELLER JOHANN
IPC: H01R13/627
Filed: 1976-06-25
Abstract: The latching device for a coaxial cable plug connector prevents the joint from being unintentionally disconnected by tensile stresses. It is usually mounted on racks for telecommunication equipment such as computer terminals in an office. A bracket (5) is fixed to a vertical strut (4) which supports the instrument rack. The office cable (3) leads to the back of the bracket with the rows and columns of the terminal contacts. The connector has a guide bush (2) with a slot (1). The associated coaxial socket (6) has a bent clamping spring (9) which is held in position by a nut. The nut engages in the slot (1) of the guide bush.

Title: Flexible plastics container for tooth-paste - is supported in inverted position on spike fixed to wall
Inventor: HEINLEIN KARL HANS DR
IPC: B65D35/56
Filed: 1976-08-23
Abstract: A container (15) for toothpaste is in the form of a small bottle made of flexible plastics. The bottle is provided with a screwed neck (25) for a cap.

Title: Wave shed loom - having guide eyes for different warp sections to simplify weaving of simple fabric structures
IPC: D03D47/26
Filed: 1976-10-01
Abstract: In the control of the warps on a wave shed loom, the warps are divided into two sections.

Title: Safety valve for pressurised flowing fluid - has externally mounted valve seat with internal bellows and valve spring unit
Inventor: JONAS CHARLES JULIUS
IPC: F16K17/08
Filed: 1977-02-02
Abstract: The safety valve is for pressurized flowing fuids and is designed no to become jammed or to seize up when required to operate after long periods of inactivity. It comprises a housing (1), a valve seat (3) mounted outside the housing, and a bellows (4) which is located inside the housing and aligned axially to the valve seat. A spring unit (19) within the housing forces the bellows into a first position in which the valve seat is held closed. A valve shaft (12) couples the valve seat to the spring unit. The function of the valve depends solely on the pressure and hence it can be operated using practically any flowing mediu.
Patent DE-2708697-A1 (DE)
Title: Sediment sepn. from fermentation tank - in vessel sepd. from vat by accelerating restriction
IPC: C12C7/26
Filed: 1977-03-01
Abstract: Sediments are removed from fluids, e.g. beer during fermentation in a vat by passing the fluid in the lower part of the vat through a narrowed cross-section so that is accelerated in the vertical direction. This speeds up the accumulation of the heavier sediments below the narrower part so that they can be extracted as required. Process enables the brewer to remove sediments and excess yeast by a method which can be carried out in the same vat, thus simplifying the process.

Title: Traffic lights red lamp monitoring system - compares phases of command signals and lamp currents and lamp operation or failure is inferred from it
Inventor: ZELLER RICHARD
IPC: G08G1/097
Filed: 1977-07-27
Abstract: The lamps are monitored for unwanted failures. The lamp current is detected by a current transformer in series with the lamp. The appearance of a static signal in a normally dynamic signal (ST) in a through loop (terminals (17, 18) of a signalling unit (7) is evaluated as the criterion for faulty operation or failure. The static signal is derived from phase comparison of a signal passing in two directions through the loop (17, 18). One direction carries the switching signal for the red light, and the other a specified min. current of the red lamp. The flow of the dynamic signal (ST) is interrupted only in case of a deviation between the switching on command and lamp min. current, or between switching off command and absence of lamp current.
Patent DE-2735246-A1 (DE)
Title: Control system for centrifugal compressor - has coupling between anti-stall control loop and main control loop to improve stability
Inventor: EWE KURT ING GRAD
IPC: F04D27/02
Filed: 1977-08-04
Abstract: The compressor (1) discharges into a pipe (2). The flow (Q1) is compared with a desired value (WQ1) and the difference (Xd1) fed to a proportional integral controller (3). This adjusts the stator blades of the compressor to maintain the desired flow. A second controller (4) operates a blow off valve (6) in accordance with an error signal (Xd2) generated from the difference between the suction flow (Q2) and a function (f) of the discharge pressure (pf). This is used to prevent the flow dropping below the stall point. Functional amplifiers (8, 11, 10) produce a signal which is the quotient of the rate o f change of the second error signal and the second error signal itself. This quotient is added (13) to the first error signal (Xd1) to improve the stability of control.

Title: Web coating blade - has a double spreader blade with a coagulation-glazing fluid to pass between them to be spread over the cladding
Inventor: WIMMER GUENTER WILHELM
IPC: B05C11/04
Filed: 1977-09-01
Abstract: In coating a web material with a fluid cladding, such as paper or film or textiles, a blade unit spreads the fluid over the web. Two blades are used in the unit, which can slide against each other, forming a gap of 0.1-0.6 mm. between them. A glazing fluid is passed through this gap between the blades so that the upper blade can apply a gloss to the coated matter on the web. The design allows a second blade to correct any coating errors or irregularities imparted by the first blade in spreading the cladding over the web, and allows a precise thickness of the cladding to be made.
