Title: Combined accelerator and brake pedal - with two part pedal with contoured end pivoted in two orthogonal directions
Inventor: ZWERENZ CARL MARIA
IPC: B60T11/10
Filed: 1974-05-03
Abstract: The combined accelerator and brake pedal is pivoted on the floor of the vehicle about a first axis so that the brakes are applied when the pedal is depressed. The edal shaft is made in two sections and partway up the shaft it is hinged about a second axis at 90 deg. to the first. Pushing the pedal sideways about the second axis operates the throttle linkage via a cable drive. The pedal is profiled so that the driver's foot grips it for the lateral movement. The fixed part of the pedal support is fitted with a cam which engages a peg on the side of the pedal shaft to push the pedal into the neutral setting when the brakes are applied.

Title: Material discharge in sawmills - holds arrangement for material until cutting is completed to avoid ends breaking off
IPC: B27B31/08
Filed: 1974-06-12
Abstract: The arrangement is for material discharge, from circular or gang saws of tree trunks, where the centre portion is the main product and the side section a secondary product. While the main trunk slides away on a beam, the unsupported side sections are held by a series of locking metal sheets suspended from a frame work. These sheets (7), which grip the trunk sides as a V are joined at the top end and tensioned by springs (11), which hold the sides until cutting is completed before allowing them to fail. This saves premature breaking off and valuable footage of saleable timber.

Title: Reciprocating fuel pump with electro-magnetic drive - has armature and coil accurately centred with coil locked in position
Inventor: GERWIN REINHARD
IPC: H02K33/04
Filed: 1974-08-07
Abstract: The drive is by means of a cylindrical solenoid. The non-magnetic connecting rod (5) is located by the guide bearing (7) in the body (8) of the pump. The armature (4) is fixed to the free end of the connecting rod. The magnet cylinder (13) is accurately located with respect to the armature by a suitable jig to ensure equal radial air gaps (20). The space (25, 26) between the cylinder and the magnet housing (1) is then filled with a synthetic resin or similar substance which, when hard, ensures the correct location after the jig is removed. The magnet coil (2) may be located in the same way. The electromagnetic forces on the armature are thus symmetrical, and bearing wear is reduced.

Title: Semiconductor components masked during etching - by tight clamping between smooth discs in stack centred by template
Inventor: PAKOCZY TIBOR
IPC: H01L21/673
Filed: 1974-08-21
Abstract: A method of etching semi-conductor components consists of clamping these active components between distance plates and using a centering template to obtain the correct alignment between the active components and the distance plates; the template is then removed and the exposed areas of the active components are etched, washed and dried. The etching may be carried out either by immersion or by spraying. By the use of a template, the relative positioning of the active components to their separating discs is easily obtained and clean etching of the desired areas is achieved without the need for using a protective lacquer which causes trouble in removing it later. The distance pieces, frame, screw and pressure plates are pref. made of PTFE or PVC.

Abstract: The laminated foil for masks in semiconductors production has one of its layers (ie the layer that is to be partly removed) pre-cut according to a given rectangular grid. The foil consists of a first partially removable layer and a second layer acting as support for the first layer. Both layers are of transparent material, the first layer being coloured and the second one colourless, bonded together with a non-hardening transparent adhesive. The material of both layers is such that it does not change with altering environmental conditions e.g. of plastic.

Title: Temperature monitor for electric machines - comprises shunt coupling capacitors to reduce interference voltage sensitivity
Inventor: BOCK LOTHAR
IPC: H02H5/04

The camera is suitable for recording single pictures or pictures with adjustable frequencies up to high values, e.g. 24 pictures per second. The exposure time for individual photographs is adjustable, independently of the picture frequency, within wide limits.
Patent DE-2453017-A1 (DE)
Inventor: SCHEUERPFLUG HANS
IPC: B62D49/06
Filed: 1974-11-08
Abstract: The vehicle has a drive head with a U frame whose legs (118, 122) point downwards and each bears a wheel (124). On the horizontal web of the U frame, a supporting arm (107) which can be pivoted about the axis of the web and fixed is mounted, the said supporting arm (107) bearing at its free end the drive assembly (113) and the driver's seat (106). Because the drive assembly and the driver's seat can be set in various positions with respect to the U frame, the drive head can be optionally supplemented by means of various attachments to form different working vehicles, for example a tractor, a lorry or a hooks-lift truck. <IMAGE>

Title: Identification of interruptions in DC network - with faulty contacts located with aid/of resistor capacitor circuits
Inventor: VOTZ GEORG
IPC: G01R31/02
Filed: 1975-03-25
Abstract: The switching arrangement which uses transistors for discharge of condensers used for location of faulty contacts causes short interruption in D.C. networks. The object is to find the faulty contacts early while they cause little damage. The arrangement comprises inductances, their potential being used to form a switching arrangement comprising several resistor-capacitor limbs each with a relatively large charging and a short discharging time constant. For differentiation between positive and negative potentials two separate arrangements are provided. The circuits comprise a Zener diode and each R.C. limb is switched via a transistor. The impulse fires the transistor so that a capacitor is discharged via the collector-transmitter line, thus changing the condition of the transistors. A thyristor is provided for discharging of the capacitor and a diode is switched after the R.C. limb so that switching takes place after recharging of the capacitor.

Title: Linear transfer function simulation - using multiple operational amplifier networks for stability flexibility and low cost
Inventor: RUPPRECHT WERNER PROF DR ING
IPC: G06G7/625
Filed: 1975-04-09
Abstract: The method is for producing electrical networks with defined linear transfer characteristics and simulating electrical or non-electrical transfer functions uses active networks for stability, flexibility, and relatively low cost compared to passive network methods. The method enables simulation of phase, damping and/or time response characteristics. Reactive elements (Al - An) are arranged in series with their inputs and outputs connected to a summation circuit via amplifying elements (Co - Cn) representing coefficients. The circuit input (Ue) is connected to the input of the first reactive element (Al) and the output (Ua) is the summation output. Operational amplifier circuits instead of reactive-resistive circuits are used, permitting large numbers of stages. Variable resistors used in conjunction with amplifiers representing coefficients permit easy adjustment of characteristics.
