Patent DE-2456880-A1 (DE)
Title: Brake control for hydrostatic drive vehicle - with brake pedal moving drive to neutral without altering position of drive control lever (SW280676)
Inventor: SMITH KENNETH
Filed: 1974-12-02
Abstract: The hydrostatic transmission is fitted with a single control lever which can be moved in either direction, from a neutral setting, to move the vehicle either forwards or backwards at selected speeds. In order to improve the control of fork lift trucks etc., the brake pedal linkage is coupled to the transmission control in such a way that when the brake pedal is operated, not only are the wheel brakes applied, but the transmission control linkage is altered so that the pump is set in the neutral setting. The control lever remains in its original setting. This allows the vehicle to resume its course after the brake is released, and releives the driver of having to rest the control lever.

Title: Network for determining potentiometer settings in situ - tests the potentiometer voltages and gives a digital display
Inventor: JOHN REINHARD ING GRAD
IPC: G05B23/02
Filed: 1974-12-19
Abstract: The test network is for finding potentiometer settings in an operating circuit-typically a control circuit-without the need for switching off or conducting a detailed examination. Typically, the gain of a PID controller might be set by means of a potentiometer, and the setting of this may require to be examined without interfering with the control system operation. The circuit (3) for doing this tests the voltage across the potentiometer at a particular instant and by means of suitable storage and comparator circuitry finds the potentiometer setting which it then displays in digital form. It achieves this with two sample and hold circuits (11, 12) constructed of linear feedback amplifiers and sampling switches (18, 19). The output of one of these is fed via a further amplifier (10') to an analogue digital converter (13) to a digital display unit (14).

Title: Aggregate for bituminous road-building materials - by comminuting-sieving coarse aggregate pieces-heating selected fraction with dry sand
Inventor: SCHUSTER RUDOLF
IPC: E01C19/05
Filed: 1975-02-20
Abstract: Bituminous road-building materials are produced by (a) classifying dry coarse aggregate pieces, e.g. crushed limestone, into individual aggregate fractions by comminuting/sieving under dry conditions, with continuous discharge of the formed dust, (b) heating the dust-free, dry aggregate with dry sand in a drying drum to a temp. above 100, esp. 150 degrees C, in less than 3, esp. 5 mins., and (c) intimately mixing the aggregate/sand with bitumen in a mixer. This gives a high quality, hard, aggregate having a desired grain size from the natural stone, at a low cost, esp. as the amount of heating oil is considerably reduced. The bitumen can penetrate into the fine pores and openings in the aggregate to give a high quality material in which the bitumen and aggregate is permanently bonded.

Title: Electric power HV switch drive brake - has braking disc cams meshing with stop crank at end of switching movement
Inventor: LEHMANN HORST ING GRAD
IPC: H01H3/60

Title: High reliability gas pressure control valve - is for use with gas heating equipment and uses multiple membrane pressure difference detection with failsafe feature
IPC: G05D16/06
Filed: 1976-03-04
Abstract: An input post with attachment flange (3) leads to an input chamber (7) while an output port with a similar attachment flange (2) leads from an output chamber (6). This is connected via an open tube (35) to a pressure chamber (37) which is bounded on upper and lower surfaces by an array of flexible membranes (20, 24, 25). These operates a sealed (11) connecting valve (10) between that and outlet chambers, in conjunction with adjustable (34) and failsafe (53) springs. A further chamber (30) above the upper set of membranes (24, 25) is open to the atmosphere (39). If the outlet pressure falls the pressure in the measurement chamber (37) falls and, below a threshold set by the spring (34) tension, this opens the control valve (10). Sufficient output pressure rise closes the valve. Failure in the membrane array results in valve closure under the action of the failsafe spring (53).
