Patent DE-2947518-A1 (DE)
Title: Baling press with three presses - which compress bale in two mutually-perpendicular planes and in two opposite directions
IPC: B30B9/30
Filed: 1979-11-24
Abstract: A baling press for textile fibres described in the parent patent has a press box having one side wall formed by a preliminary press plate which horizontally compresses the charge in the press box to the required bale width, and a main press which compresses the charge vertically to the final size. The main press comprises a main press plate in the upper surface of the box, opposed by an active counter-press plate in the lower surface, which is similarly mounted on the piston-rod of a hydraulic press so that the main compressing action occurs from two sides of the bale, in opposite direction. This construction gives a more uniform compression of the bale than the uni-directional action of a single main press.

Title: Fast multiplier which multiplies decimal numbers - employs complement for digits greater than five and forms further complements using algorithmic logic circuit
Inventor: PETERS ARTHUR
IPC: G06F7/496
Filed: 1979-12-22
Abstract: The multiplier determines first whether the value of a selected digit in the first of the two numbers being multiplied is greater than a given value (e.g. five). If it is not then a selected digit in the second number is added to itself until the value of the selected digit is reached. If, however, the digit is greater, then the following occurs; the complement of the selected digit is generated; the value of the given digit is subtracted from a given value until the complement of the selected digit is obtained; the complement of the result of this subtraction is then formed. The process enables computation time to be saved.
Patent DE-3000998-A1 (DE)
Title: Controlling lens focal length of slave TV camera - using voltage to frequency conversion of focal length-dependent voltage signal from main camera
Inventor: DUESING MICHAEL ING GRAD
IPC: H04N5/272
Filed: 1980-01-12
Abstract: The principal application of the control system is for simultaneous recording of a studio subject and a different live background picture. To maintain compatibility of the two pictures it is desirable, when using zoom lenses, that both cameras operate with identical settings for the lenses. The studio camera acts as master and is under the control of a camera man. A transducer fitted to the zoom appts. produces a d.c. voltage proportional to the set focal length of the camera lens. A converter changes the voltage level into an alternating signal whose frequency is proportional to the d.c. voltage. After transmission to the slave camera the frequency is reconverted into a proportional d.c. voltage which, in turn, acts as reference for the lens setting drive. Digital signals may be employed instead of frequency.

Title: Method and device for analysing dispersed aerosol compositions
Inventor: RESIDOV ILDUS KERIMOVIC
IPC: G01N27/60
Filed: 1981-02-11
Abstract: The invention relates to the determination of physical and chemical properties of materials, in particular to an analytical method for dispersed aerosol compositions and a device for carrying out the said method. The analytical method for dispersed aerosol compositions comprises a fractionated deposition of particles on deposition surfaces of a cascade impactor and determination of the mass of the deposits of particles, followed by removal of the particles from the impactor. The particle mass is determined by creating a potential difference between the deposition surfaces and measuring the electrical charge which is transferred by the particles from one deposition surface to the other under the action of the potential difference. The particles are removed by passing by a dedusted gas through the impactor with a potential difference present on all the deposition surfaces. The device for carrying out the method comprises a cascade impactor having chambers, an electrical switch, a direct-current source and a charge measuring device. The chambers of the impactor are arranged in the direction of flow of the aerosol. Each chamber is bounded by two diaphragms. The lower diaphragm viewed in the direction of flow of the aerosol serves as deposition surface for the particles and has nozzles for the passage of aerosol to the next chamber. The inputs of the electrical switch are connected to the diaphragms of the impactor, while its outputs are connected to the direct-current source and the charge measuring device. The method and device can be used in automatic systems for monitoring the fraction content of aerosols in technological processes, in industrial offgases and in the air. <IMAGE>

Title: Process for preparing N-cyclohexylbenzothiazole-2-sulphenamide
Inventor: KACANI STANISLAV DIPL ING
IPC: C07D277/80
Filed: 1981-07-09
Abstract: The invention relates to a process for preparing N-cyclohexylbenzothiazole-2-sulphenamide. The process is based on 2-mercaptobenzothiazole being initially reacted with excess cyclohexylamine and the resulting solution of the cyclohexylamine salt then being oxidised with an oxidising agent, e.g. with sodium hypochlorite. The by-products of the oxidation are separated off, for example by filtration. The 2-mercaptobenzothiazole can be employed in the form of a crude reaction product which arises as waste in the industrial high-pressure reaction of aniline, carbon disulphide and sulphur. The process gives high yields and a high degree of product purity and is simple to carry out on an industrial scale.

Title: Deceleration-associated actuation of brake lights
Inventor: BRODTMANN NORBERT L ING GRAD
IPC: B60Q1/44
Filed: 1981-07-29
Abstract: The invention relates to a drive system, preferably for motor vehicle brake lights, for avoiding dazzling following traffic. Since dazzling occurs only when the following motor vehicle is located directly behind the vehicle in question and this occurs in a manner likely to affect traffic safety only when traffic is stationary - when traffic is moving the safety distance is maintained - according to the invention the additional brake lights are switched off as soon as the motor vehicle comes to a standstill even if the driver stops the vehicle with the footbrake. The absence of the braking deceleration force is detected as a standstill criterion by a deceleration sensor and in the control electronics it permits the additional brake lights to be operated even when the vehicle is stationary, in the event of a particular hazard.
Patent DE-3132239-A1 (DE)
Inventor: KIMPEL ROLF-DIETER DIPL PHYS
IPC: H01H50/60
Filed: 1981-08-14
Abstract: An electromagnetic relay has a bar-shaped armature which is mounted at one end at a coil flange in a carrier comprised of insulating material, in which center contact blades are also mounted at opposite sides of the armature such that movement of the armature is transmitted to the contact blades through the carrier, thus eliminating the plunger which is normally present for contact actuation. The offset positioning of the contact blades with respect to the armature in the carrier causes friction which substantially prevents damaging impact of the contact pads of the contact blades with respectively mating stationary contact pads.
