Patent DE-2746817-A1 (DE)
Title: Tool securing assembly for press - has switch acting between cams to provide braking signals
Inventor: HIERL ROBERT
IPC: B21D43/02
Filed: 1977-10-18
Abstract: The tool securing arrangement for a press has a tooling protection switch actuated in response to the feed. The bypass region is formed by a slotted circular cam (13) interrupted in the region of the feed end for actuating the tooling protection switch (3). This tooling protection switch for interrogating faulty position cam is effective in the region briefly before the press ram enters the material. The signal it is analysed in a further connected cam (16) which initiates braking.

Title: Variable capacitor for frequency filters - has flat metal part slightly spaced from fixed capacitor and coupled to one capacitor terminal
Inventor: WENDEL WOLFGANG DIPL ING
IPC: H01G5/16
Filed: 1977-11-18
Abstract: A fixed capacitor (C7, C8) is provided with a flat metal part (5) in a slight mutual spacing. The metal part and one terminal of the capacitor are conductively connected. Preferably the surface of the metal part is at least of the same size as the directly opposite surface of the capacitor. The surface of the metal part opposite the capacitor may be coated with an insulating layer. Alternately the metal part may have several shanks (6, 7) coupled together by a transverse strip (10. The latter may have fasteners, serving simultaneously as electric terminals. The metal part may be of one-piece construction and may be of flexible, non-spring material.
Patent DE-2752025-A1 (DE)
Inventor: PERRET MAURICE
IPC: H01G4/32
Filed: 1977-11-22
Abstract: The capacitor has two electrode units (21, 22), each with several capacitor plates (42, 44), which are fixed to a bearing part (27, 33). The plates (42) of one electrode unit (21) engage with the plates (44) of the other electrode unit (22), and vice versa. All the plates (42, 44) of the two electrode units (21, 22) are arranged parallel to a straight line (47), along which one electrode unit (22) can be adjusted relative to the other (21). Each of the two electrode units (21, 22) has guides (48, 49, 50) adjacent to the bearing part (27, 33) for the free edge of each capacitor plate (42, 44) of the other electrode unit. The guides (48, 49, 50) are intended to hold the free edge of each plate (42, 44) of the other electrode unit (22, 21) in a predefined position relative to the plates of the first electrode unit, if both electrode units (21, 22) are set to the maximum depth of engagement of their plates (42, 44). At other settings, however, the guides (48, 49, 50) do not engage with the plates (42, 44) of the other electrode unit. For manufacture of the capacitor, this formation simplifies the correct orientation of the plates (42, 44), and also of the two electrode units (21, 22), relative to each other. This variable capacity capacitor is particularly made in the form of a vacuum capacitor. <IMAGE>

Title: Comb strip for clamping connecting wire ends - accepts wires of different diameters between folded over ends of tines and next tine
Inventor: SCHMIDT ALFRED
IPC: H02B1/20
Filed: 1977-12-29
Abstract: The wire holder comprises a comb-like rail in which each individual tooth (51) is bent over so that its free end (72) is close to its root (80). The inward pointing part may have indentations (79) for secure holding of the connecting wires (81). The spring properties of the teeth assisted by the folded over construction ensures that the wire is gripped between the free end of one tooth and the root end of the next, and also make it possible to hold two wires of different diameter. The rail may be attached to the mounting base of electrical appts., by means of an adhesive strip or simiral arrangement.

They are applied in forms which float (to control floating weeds), sink (to control weeds with roots in the immersed soil) or evenly distribute (I) throughout the water. Typical solvents for (I) include citrus terpenes, petroleum distillates and water. The concentration of (I) applied is 0.25-10 wt ppm (pref. 0.25-2 wt ppm). They are used at levels which inhibit the growth of the weeds but do not kill them. Activity tests are described e.g. most of the cpds. give a 75-100% inhibition of the growth of Hydrilla verticillata when used at concentrations of 10 ppm.
Patent DE-2801561-A1 (DE)
Inventor: DIETRICH MARTIN DIPL ING
IPC: H03K3/537
Filed: 1978-01-14
Abstract: When the high-voltage test generator, which is constructed as a Marx multiplier circuit, is used as a test switching voltage generator only those stages (A1) which are relatively close to earth are used, while the upper stages (A2) can be changed, by switching elements (7, 11) which can be used selectively, into one of three switching states which are inactive for switching-voltage production:     a) all the upper generator stages are short-circuited, b) the upper generator stages are charged with a charging voltage of opposite polarity, and c) the upper generator stages are connected together in a combination in accordance with a) and b).   In the transition region between the stages (A1) which are relatively close to earth and the upper stages (A2), an additional large-area screening electrode (8) is arranged which is connected upstream of the head screening electrode (9) of the test generator. The purpose of the invention is to improve the utilisation of the test generator in the production of positive aperiodic or oscillating test switching voltages, and makes it possible to improve considerably the ratio of the test switching voltage which can be achieved to the cost for producing and designing the head electrode. <IMAGE>

Title: Variable effect handbrake lever - has integral linkage including triangular lever to reduce initial play travel
Inventor: SCHROETER HANS O
IPC: B60T7/10
Filed: 1978-02-08
Abstract: The handbrake cable is linked to a triangular lever (5) pivotted under the handbrake lever (2) support and linked to the handbrake lever by an intermediate link lever (7). This is pivotted on the handbrake lever at a point near the triangular lever pivot (8) in the rest position, and provides a variable effect linkage as the slack is rapidly taken up. As the slack is taken up the mechanical advantage alters, with the pivot points moving apart, so that a greater force can be applied to the handbrake cable. Handbrake lever travel is kept to a minimum so that a positive braking effect can be achieved.

Title: Egg quality inspection device - uses selective light transmission and intensity measurement by receiver signal comparison circuit
Inventor: FURUTA NAOFUMI
IPC: G01N33/08
Filed: 1978-02-15
Abstract: An egg inspection device determines egg quality without damaging them. A projection illuminates the egg. A receiver detects light passing through it in the wave band from 575 m mu to 590 m mu and generates corresp. output electrical signals. A calibration device calibrates the signals for 575 m mu w.r.t. the 590 m mu signals and generates a calibration signal which is compared with a fixed signal associated with eggs containing blood. The comparison circuit produces an output signal when the levels coincide.

Title: Self-adjusting mechanical vehicle clutch linkage - has resetting wheel mounted on clutch pedal in mesh with segment disc, with sprung pawl lifted
Inventor: PAPE ERWIN ING GRAD
IPC: F16D13/75

Abstract: A master storage cell chain (TM) is to change state with each clock pulse and in synchronism with a slave storage cell chain (TS) using the same clock pulses. Interference can cause loss of cynchronisation. The master chain amplitude modulates the clock pulses at intervals determined by the state of the master chain. A signal recognition circuit (SES) recognises the amplitude modulated pulses and triggers a correcting circuit (KSE) to set or reset the slave chain so as to be re-synchronised with the master.
