Title: Connector for window hollow sections - connects mitred ends of sections by corner with notches engaging pressure plates inside (NL250177)
Inventor: KREUSEL ULRICH
IPC: E06B3/976
Filed: 1975-07-23
Abstract: The connecting kit for hollow sections is for use on window or door structures. A corner piece has notches on its legs which correspond to noses and engage to form at the same time pivoting points for the rocker arms (3, 4). The light of the clear gap of the hollow section is reduced near the mitre ends. When the mitred end is pushed over the leg with the respective arms in place, first ends (7, or 8) are pressed downwards by the reduced clear profile and by an indent provided near the section end. When the indents pass the other end of the rocker arm, lips are pressed down and kept in position by the indent.

Title: Optimum valve for character recognition of unsegmented symbols - using a primary and secondary evaluation to generate optimum value
Inventor: RIESTER WOLFGANG
IPC: G06V30/10
Filed: 1975-09-29
Abstract: A character recognition system for unsegmented alpha-numeric characters is based upon a primary recognition process followed by a secondary recognition to obtain an optimum result without intermediate storage. The character pattern (1) is transmitted over a converter to provide information for a classification unit and a space indicator. An initial classification signal (S2) and a best comparison value (S13) are entered into a memory, either as a data matrix row by row digitisation. The memory is scanned to generate data for an evaluation circuit coupled to logic circuit to generate the primary evaluation. A second circuit is controlled by an interval timer to evaluate the optimum value during the period between samples. A memory provides an acceptable signal for the output control unit.

IPC: E01C19/20
Filed: 1975-11-21
Abstract: The scatterer facilitates even spreading of sand, thawing-salt, or other bulk material, by hand, where large-scale mechanical distribution is not permissible, because of confined spaces, as on paths in parks or gardens, to avoid damage to plants. It is inexpensive enough for private household use. It comprises a beaker or box-shaped container with a flat bottom. It is open on the scattering side, and has a handle on the opposite side. On the scattering side there is also a distribution surface, bordering the bottom with perforations in it. It may widen in cross-section towards the direction of spreading, and may be semicircular or rectangular. There may be a protective projection near the top.

Title: Vacuum band filter for liquids - has air seals at edges of band supplied with filtrate as sealing liquid
Inventor: MILLER PETER ANTHONY
IPC: B01D29/09
Filed: 1976-11-05
Abstract: A vacuum chamber filter for liqs. operates with a filter band which is moved forward by steps, remaining stationary during each filtering phase. To prevent air entering the appts. through the sealing faces of the filter and ensure tight vacuum, a portion of the filtrate is supplied to the sealing surfaces. Pref. the filtrate is recycled from the pressure side of the filtrate pump to an inlet which supplies a sealing groove in the face of a filter plate. From the region of the seal, the filtrate flows out from a second groove into the filtrate discharge chamber. Suitable for use in the chemical, pharmaceutical, drinks, foodstuffs or similar industries where contact of air with the liq. must be avoided. The method is much simpler and more effective than previous arrangements, e.g. the use of gas. Filtering can be carried out continuously and automatically.

Title: Generation of signal patterns for subscriber request - using two current flow detectors delivering signal patterns which can be immediately evaluated (BE 2.10.78)
Inventor: KRAEMER DIETER DIPL ING
IPC: H04Q3/545
Filed: 1977-03-31

It is applied to current flow detectors in at least two subscriber current circuits, respondin to threshold values, and to other signal receivers of a sequentially operating evaluation device carrying out the necessary connection functions. At least one of the circuit state signals delivered by the current flow detectors (A, B) is split into two, staggered in time, sequential signals (F2, F3), and an immediately evaluable bit pattern (K1-K8) containing all state signals (F1-F3) is produced.
Patent DE-2722677-A1 (DE)
Title: Delay switch for automatic burner - has solenoid connected to thermal trip to switch off fuel if flame fails
Inventor: SCHWARZ SIEGFRIED
IPC: F23N5/08
Filed: 1977-05-18
Abstract: The automatic burner system has a thermal switch for providing a safety delay period of less than one second when the flame is extinguished. The thermal switch is also used for rapid switching off in case of disturbance. When the flame relay drops while a control element still requires heat and while the main voltage is still connected, then the armature (12) of the solenois (13) is connected to the tripping mechanism (3) of the thermal switch (1) mechanically. This ensures that any actuation of the armature (12) will result in tripping. If the flame fails during operation then the flame relay drop results in a pulse which briefly pulls up the armature (12) to ensure tripping.
Patent DE-2739881-A1 (DE)
Title: Manually operated pump for grouting anchors in masonry holes - has outlet with alignable holes in relatively rotatable plates to form control valve
Inventor: FISCHER ARTUR DR
IPC: B05C17/00
Filed: 1977-09-05
Abstract: The injector has an opening(4) through which the grout is forced by manual depression of a plunger. The opening can be closed at the termination of the injection phase to obviate a reversal of grout flow at the mouth of the hole. The head of the injector may be covered by two parallel plates (12, 13), each with an offset opening, and forming a simple slide valve. The external plate(12) may be rotated to effect the coincidence of the openings or vice versa. The outer plate(13) may have an axially projecting nose(9) with a radial projection(10). The nose(9) engages a matching recess (11) in the anchor unit(7) to positively locate the injector at the start of the operation.

Title: Thyristor ignition control circuit - has three AND=circuits, monostable flip=flop and control counter in logic circuit output stage
Inventor: MATEJKA JAROSLAV DIPL ING
IPC: H02M1/088
Filed: 1977-10-13
Abstract: Thyristors feed signals back to a circuit which comprises a control counter and an output logic unit. It is controlled by double and single pulse control telegrams generated in a central control unit. The double pulse initiates the ignition phase, and the single pulse initiates individual thyristor monitoring and measurement phases. Control telegram pulses are applied to a first AND circuit (G1) and a first monostable flip-flop (M), whose output pulses (m) are applied to a second AND circuit (G2) and to a second input of the first AND circuit (G1) whose output pulses set the counter (Z) to its ignition position (fR). Its last position (N + 1) delivers a pulse to a third AND circuit (G3), and inverted pulse to the second AND circuit (G2). Second AND circuit output pulses (c) are applied to the counter timing input. The flip-flop (M) inverted output pulses (m) are applied to a third AND circuit (G3) whose output signals represent signalling back for the ignited thyristor.

Title: Adjustable ski for wide range of use - has section under binding exchangeable for varying glide characteristics
Inventor: PODHORA PAUL V DIPL ING
IPC: A63C5/04
Filed: 1978-01-23
Abstract: Ski, exp. for long-distance runs, has a running surface whose front and rear sections are made of a low-friction plastics, e.g. polyethylene. That section of the running surface beneath the binding (about one-third of the total ski length) is exchangeable. That section is fastened to the main body of the ski rigidly and non-elastically, by means of a "climbing band". Exchangeability of sections of the running surface enables the ski, as claimed, to be used by skiers of various degrees of accomplishment and on slopes of widely different difficulty since its "slip" can be adjusted as desired.
