Abstract: There are two different types of control units consisting of storage registers connected in parallel to record and reproduce access requests to the central memory. Some of these control units are assigned to a processor and are controlled by means of timing pulses delayed in relation to the basic cycle of the central timing generator by the amount of the signal time corresponding to the distance between priority mechanism and central memory and between central memory and processor. Others are assigned to a priority mechanism and so divided that some of their registers are controlled in diminishing sequence by timing pulses delayed in relation to the basic cycle.

Title: Variable resistor with light indication - light inside slider head varying in intensity with resistance caused by slider movement
Inventor: OKA SHUNZO
IPC: H01C10/38
Filed: 1974-03-15
Abstract: The variable resistor consists of a rectangular housing with a slit along its top surface to allow the slider arm to move along. The slider head contains a lamp connected by wires down through the slider arm to contacts on the part of the slider inside the housing. The resistance material is fixed to the base of the housing and lies parallel to the fixed contact paths over which the slider contacts move. As the slider is moved along, the resistance varies and so does the current through the lamp. The lamp intensity therefore gives an indication to the resistance value. The arrangement is particularly useful in audio replay systems.

This reduces corrosion on the trailer frame end on the brakes etc., while the caravan is well protected from weathering.
Patent DE-2420689-A1 (DE)
Title: Method for improvement of loudspeaker properties - applies to natural and lower frequency ranges
Inventor: KLINGELNBERG ARNDT
IPC: H04R3/00
Filed: 1974-04-29
Abstract: The response characteristic of a loudspeaker is improved if it has a rapid acceleration. Improvement is achieved by movement negative feed back, and frequency correction is realised by positive feed back. A signal proportional to the coil current is positively fed back through a low pass filter, whose cut-off frequency lies in the oscillator natural frequency range ((+-) 1 octave). The lower cut off frequency of the power amplifier ensures a high-pass filter characteristic with a steep flank, suppressing very low frequencies outside the required range. The system also minimises parasitic oscillations.
Patent DE-2425167-A1 (DE)
Title: Black-white TV signal regenerating system - eliminates grey using black-white discriminator and adds amplified sync. pulses to signal
Inventor: KIRSCH CARL MARTIN
IPC: H04N1/403
Filed: 1974-05-24
Abstract: The black/white television signal regenerating system has the noisy television signal applied to an input amplifier (1). For this purpose the TV signal may be produced by a camera viewing a projected microfilm. The input amplifier divides the TV signal into two parts having the same information content. The first part is applied to a discriminator (2), and the second one to a separating stage (3). The discriminator evaluates its input signal in terms of grey level and produces a black signal when a given threshold is exceeded, or a white signal when it is not exceeded, thus eliminating the grey. The separating stage amplifies the sync. pulses and suppresses the rest of the signal. The outputs of the separating stage and the discriminator are then combined (4) to give the proper TV signal.

Title: Automatic stopping mechanism for electronic taped "juke" box - has centrifugal coupling mechanism which operates when the source voltage drops
IPC: G11B15/22
Filed: 1974-06-24
Abstract: The stopping mechanism has a driven rotor filled with a sensing element. Its circumference comes into contact with a tape reel or a disc linked to that reel. The sensing element is driven by the rotor and both turn as a single unit. When the reel or disc comes to a halt, there will exist a relative angular displacement with respect to the driven rotor. This alters the sensing element and an operating mechanism wih a centrifugally adjustable catch. This in turn operates the locking mechanism and stops the tape.
Patent DE-2431534-A1 (DE)
Title: Flexible nylon pressure hose has helical reinforced cords - sliding between inner and outer tubes to give high flexibility
Inventor: CHROW ALBERT E
IPC: F16L11/04
Filed: 1974-07-01
Abstract: A hose comprises inner and outer tubes, of nylon with intermediate, tensioned, helical reinforcing cords also of nylon but having a considerably higher fusion temp. than the tubes. The helical cords are of opposite lays (right and left hand) and of a sufficiently wide pitch to form large panels of clear space between the turns; in these spaces the inner and outer tubes are welded together, whereas the reinforcing cords are not welded to the tubes or to each other, so that when the complete hose is bent or subjected to flexing oscillations, the helical cords can slide by a certain amt. inside the tube wall. Pref. the tubes are of self-condensation products of amino-hendecane acid, and the cords are of a polyhexamethylene adipamide.
Patent DE-2434732-A1 (DE)
Title: Coherent impulse doppler radar system - designed esp for low impulse sequence frequency and suppressing slow ground echo signals
Inventor: HUGHES ROBERT B
IPC: G01S13/524
Filed: 1974-07-19
Abstract: The objective is a radar sytem which blocks echo signals from ground vehicles and provides accurate information relating to the location of relatively fast air targets. The system has a send/receive unit whose sender unit is triggered by an impulse generator which generates sequentially groups of trigger impulses, each with a sequency frequency differing from that of the previous group. The sender accordingly generates radar output impulses whose sequence frequency changes during a target delay period i.e. the period required by the antennae to scan the target. The reflected echo signal received by the antennae is fed through the unit's receiver to a digital clutter-attenuation band-comb filter and control circuit.

Title: Turning installation for pairs of boards - alternate boards in conveyed row turned and stacked on remainder
Inventor: GRENZEBACH RUDOLF
IPC: B65H29/58
Filed: 1974-08-13
Abstract: Procedure for turning and placing a pair of boards on top of each other with identical surfaces, by which, from a row of boards delivered by a conveyor, each second board is lifted and placed above the conveying plane in a vertical position to direction of conveying. Subsequently the vertical board is moved downwards towards the conveying plane and during a turning operation placed at corresponding speed on below it conveyed board. The on top of each other placed boards are lined up and taken away by the conveyor. This arrangement requires shorter operating time than previously. For one thing, the boards are not taken out sideways from the conveyor and replaced together again.
