Patent DE-2553424-A1 (DE)
Title: Master lock mechanism for drawers - has vertically movable notched elements working together with drawer movement operated locking angles
IPC: E05B65/465
Filed: 1975-11-27
Abstract: The drawer locking mechanism has on each drawer an angled plate (10) with two notches (19, 20) on the vertical leg. The plate moves only in vertical direction and it obstructs the drawing movement, when in the lower position. The vertical movement of the plate is introduced by the swivel action of the locking angle (13) fitted rigidly to a ring (22). For each drawer one angle is provided and the ring/angle assemblies are pivoting around a common axle (14) fitted in lateral direction to the drawer movement. The swivelling position of the angle (13) is controlled by a roller (25) and by the drawer movement. When one of the drawers is pulled out, the lower notch on the plate (10) tips over the angle (13), so that the leg (13b) disengages from the notch and the other leg (13a) engages with the upper notch to prevent withdrawal of all the other drawers.

Title: Variable gain circuit with coupled frequency band pass - adds signal with selected frequency band to output signal to improve sound quality using frequency sensitive impedances
Inventor: ROHRBACHER JOSEF ING GRAD
IPC: H03G9/14
Filed: 1976-03-20
Abstract: The circuit frequency characteristic varies with gain and is automatically set by the l.f. level. A control voltage derived from the l.f. signal is applied to a circuit with frequency sensitive impedances. It delivers signal(s) whose frequency characteristic is varied by the control voltage. They are added to the output signal. In order to achieve aurally correct volume control, pref. for t.v. or radio receivers, the circuit has at least three switches of which the first delivers an amplified output signal with a certain fundamental frequency variation, while the second switch adds to the output signal through a circuit with frequency sensitive impedances a signal with a selected frequency band. This switch is controlled by a further switch to which the control voltage is applied.

Title: Coating curved surfaces partic. of pipes with hardened synthetic resin - as protection against corrosion and aggressive chemicals
Inventor: STOECKL FRITZ DR
IPC: B05D1/00
Filed: 1976-06-22
Abstract: Curved surfaces, esp. those of pipes, are coated with a hardened synthetic resin (I), which is first applied in the viscous state to a flexible carrier laid on a flat surface. The carrier, the surface adhesion of which for (I) is less than the surface forces between (I) and pipe, is laid on the surface to be coated in such a way that the coating of (I) is between the surface to be coated and the carrier. (I) is then pressed on to the surface to be coated and the carrier is drawn away from the synthetic layer. (I) is pref. an epoxy resin, and the carrier is pref. a PVC sheet. A reinforcement may be introduced into the resin layer, a reinforcement of wires may be laid in under the inner surface of the concrete pipe, which when current is laid on heats and hardens the resin. This layers of resin, esp. epoxy resin which will harden on a surface with some internal humidity, can be applied as a preventive against corrosion and aggressive chemicals in sewer pipes, much more cheaply and with a more economical deployment of labour. Repeated sprayings and trowelling are eliminated.

Title: Toilet brush with detachable cleaning head - has curved shape support plate for head allowing thorough cleaning around entire toilet pan
IPC: A47L13/46
Filed: 1976-10-07
Abstract: The toilet brush comprises a handle (4), which stems from the inner curved face (3) of a curved plate (1) which serves as the support for a detachable cleaning cloth head (12) which covers the outside (2) of the plate (1).

Title: Oxygen sensor for monitoring oxygen content in exhaust gases - protected with refractory oxide coating on side exposed to exhaust gases
Inventor: ASANO MITSURU
IPC: G01N27/409
Filed: 1976-12-14
Abstract: Oxygen sensor contains a layer of a metal oxide permeable to oxygen ions; it is provided on both sides with electrodes; one of the sides is in contact with the gas whose oxygen content is to be measured; the other side is in contact with a reference gas, pref. air. A catalyst promoting oxidation of some components of the gas mixt. to be analysed is provided on the side of this mixt. The sensor is improved in that the electrode on the side of the gas mixt. is covered with a porous layer of a refractory metal oxide, a layer of a metallic catalyst particles and another porous layer of a refractory metal oxide. When there is a difference between the oxygen contents of the gas mixts. and the reference gas (air), e.m.f. is created in the sensor; its value permits the determ. of the oxygen content in the gas mixt. being analysed. This senser is esp. suitable for monitoring the oxygen content in exhaust gases of an internal combustion engine with the aim of maintaining the air:fuel ratio at the optium. The disposition of the catalyst particles between two refractory metal oxide layers prevents coalescence of the catalyst particles and their poisoning by lead, sulphur or phosphorus impurities. The electrode surface is also protected. Thus variations in the tensor's readings with time (thermal ageing) are diminished.

Title: Suppressor for data transmission interference pulses - has chain of flip=flops and logic circuits
Inventor: RADUCANU DAN-CORNELIU DIPL ING
IPC: H03K5/1252
Filed: 1976-12-17
Abstract: The suppressed interference pulses are positive and negative, and they have a certain width. A chain of D-flip-flops (D1-Dn) is triggered by clock pulses (Ck), and the useful signals (S) affected by different interference pulses is delayed by a chosen time interval. Logic circuits (N1, N2) follow the chain of D-flip-flops (D1-Dn), which eliminate in separate channels the positive and negative interference pulses. Stores (DB, DC) follow the logic circuits (N1, N2) and are controlled by negated clock pulses. They eliminate peaks still present. Cross-connected logic circuits (N3, N4) deliver the interference free useful signal in direct and inverted form.

Title: Vehicle roof lifting mechanism - has parallel levers pivoted in longitudinal slots in roof brackets
Inventor: LOHRE HELMUT
IPC: E05D15/46
Filed: 1976-12-22
Abstract: The motor vehicle roof hood can be lifted by remote actuation on a roof opening. The paired support levers of the hood are held on the hood and the frame around the roof opening. The roof covering hood is hinged and does not project beyond the roof lining into the vehicle compartment. The bearings of the lever (5) on the frame are held in guides (7) so that the levers are collapsed at an acute angle to each other when the hood (2) is lowered. This angle is constantly changed on extending the hood. The levers on one side will become parallel to each other when the hood is fully extended. Each guide is a slot (8) in a bracket (6). The slots have widened ends so that a rolling collar can be readily inserted to run in such a slot (8).
