Title: Fluid pressure regulating system
IPC: G05D7/06
Filed: 1980-12-29
Abstract: For regulating the pressure in a fluid flow line particularly an L.P.G. supply line to the carburation system of an internal combustion engine, a flow regulating device is connected in the flow line and controlled in response to the output of a pressure sensor. The sensor has a pair of chambers 13, 14, each divided into sub-chambers by a flexible diaphragm 15, the flow line pressure P1 being connected to act in one sub-chamber and the reference pressure P2 being connected to act in the other sub-chamber. A sensor coil 17 associated with each control chamber 17 produces an electrical output representative of the distance of the diaphragm from it, the arrangement being such that a variation in the flow line pressure in relation to the reference pressure causes the diaphragms to move in opposite directions relatively to their associated sensor coils. Comparator means are provided for comparing the electrical outputs from the sensor coils to provide an output for controlling said regulating device. <IMAGE>

Title: Apparatus and method for cutting gear teeth
IPC: B23F17/00
Filed: 1981-06-16
Abstract: Gear cutting apparatus and a method of gear cutting to form teeth (1) on a rack bar (2) with varying effective pitch for engagement with helically formed teeth on an axially rotatable gear component such as a pinion to provide the variation in transmission ratio includes a cutter (3) having cutting edges 4 which correspond to the profile of the gear component. The cutter (3) is reciprocated along a cutting axis (4b) by a fluid pressure operated piston and cylinder (8, 11). The piston (8) is connected to the cutter (3) through a shaft (6) threadedly engaged with a thread in a mounting sleeve (9) so that during axial displacement of the shaft (6) the cutter (3) is subjected to rotation about the axis (4b). The pitch of the thread means between the shaft (6) and mounting (9) corresponds to the pitch of the helical teeth in the gear component and during its axial and rotary movement the cutter (3) cuts through the face (2a) of the rack bar. Following cutting the rack bar (2) is displaced transversely in the direction of arrow (23a) prior to a further cutting stroke and to an extent which determines the effective pitch required of the teeth which are being cut in the bar (2). Displacement of the bar (2) is effected by a leadscrew control unit which indexes a displacement of the bar (2) through co-operating track and track followers. The cutting edges (4) are capable of being indexed through the controlled rotation of the mounting (9) by a gear mechanism (14, 15). <IMAGE>

Title: A coupling equipment for the control of access of data processors to a data line
IPC: B66B1/18
Filed: 1981-10-15
Abstract: An apparatus for controlling the access of a plurality of microprocessors at a data line. The microprocessors are connected by interface components or blocks, logic switching circuits and bus drivers with two lines or conductors. An access request or demand of a processor initiates a signal change at the first line. This signal change causes the transformation of data which is specific to the processor into a delay or a priority signal, upon the occurrence of which there is accomplished a signal change of the second line. As a function thereof there appears at an input of the interface component a signal change which is indicative of the availability of the data line. Upon simultaneous occurrence of access requests or demands of a number of processors the signal change of the second line is brought about by that processor whose priority signal possesses the smallest delay. The signal change of the second line prevents the occurrence of the priority signals possessing the greater time-delays and which are correlated to the remaining processors. At these processors there thus cannot occur any signal change at the input of the related interface component or block and which indicates the availability of the data line.

Title: Fluid flow rate and direction sensor
Inventor: OVERALL HUBERT
IPC: G01F1/684
Filed: 1982-07-09
Abstract: A device for indicating flow of fluid, e.g. air, comprises a first thermistor (14) exposed to fluid flow for generating an output signal indicative of temperature. A second thermistor (32), shrouded from fluid flow, generates a further output signal indicative of ambient temperature.
