Title: Anti-skid device for a vehicle braking system
IPC: B60T8/32
Filed: 1968-06-21
Abstract: An antiskid device for vehicle braking systems comprises an electronic sensing unit and an actuating unit for decreasing or cancelling the pressure in the braking system. The electronic sensing unit comprises a speed sensing device, such as a tachometer generator or a variable frequency generator with a detector, giving a signal voltage V proportional to the speed of the vehicle a differentiating circuit providing a signal [gamma] proportional to the acceleration and a device, such as a Schmitt trigger, which produces an output signal D while the deceleration is greater than a predetermined value. The signal D is applied to electromagnetic valves to reduce the pressure in the braking system. The above system delays but may not fully prevent wheel locking a modified system (Figs. 3, 4, not shown) prevents wheel locking until the vehicle stops. In this both the acceleration signal y and the output D of the Schmitt trigger are differentiated and applied to the two inputs of a bi-stable multivibrator. This provides a control signal for the valves which continues until point C on the speed curve when the vehicle is again moving at constant speed.

Title: Electron Gun Manufacture
IPC: H01J3/02
Filed: 1968-10-22
Abstract: A method of making an assembly comprising a plurality of elements of sheet material arranged parallel to and behind each other and provided with apertures in coaxial alignment, which method includes securing the components in their correct relative positions before providing the apertures and then forming the apertures by spark erosion in a flowing liquid. Electrodes 1, 2, 3 of an electron-gun are arranged on a jig (not shown) and welded to supporting rods 4 which are sealed in glass rods 5. After removing the jig, the assembly is placed on a centring jig 6 and the electrodes connected to one terminal of a spark generator power supply 11. An electrode 7 is moved forwardly to make progressively larger holes in the electrodes and during this process the assembly is in a flowing liquid, e.g. deionized water, to remove metal particles released by the sparks. With deionized water, to avoid electrolytic pickling of the apertures, a pulse generator may be used or the polarity of the spark voltage may be inverted. The apertures may be of any shape and if desired the largest aperture may be formed in the intermediate electrode.

Title: Wide band antennas
IPC: H01Q19/10
Filed: 1970-01-29
Abstract: An aerial unit comprises a symmetrical arrangement of two flat conductive surfaces disposed in dihedral formation and having a flattened apex, a radiating slot formed along said apex, and a cylindrical reflector inside said dihedron, its axis being parallel to said apex. In an embodiment, three slotted dihedra 9, 10, 11, Fig. 2, are symmetrically disposed around a cylindrical supporting mast 8, which acts as a reflector. The slots are supplied at their centres with equal co-phasal powers, to provide an omni-directional radiation pattern. The internal angle of the dihedra is from 90 to 100 degrees. The length of the slots is approximately X (X = wavelength at the mean frequency of transmission) and their width is X/10. The diameter of the mast 8 is approximately 2X/3 and the distance between the slots and the mast is X/3. Pairs of conductive supports attach the three dihedra 9, 10, 11 to the mast 8, the upper members 15, 16, 17 of which are seen in Fig. 2. These supports are positioned at voltage nodal points on the dihedral plates, and they provide short-circuits for the ends of the slots, which may therefore be left open. Radome devices 17, 18, 19 protect the slots against frost. Several stages of slotted dihedra may be provided, one above the other, to boost the gain of the aerial. The dihedra around the mast may be supplied with power inputs which differ in amplitude or phase, if a directional radiation pattern is required. The slots in the dihedra may be of non-uniform width over their length, in order to improve impedance matching over a wide frequency band (Fig. 3, not shown). In another embodiment, a part cylindrical reflector is provided behind a slotted dihedron (Fig. 1, not shown).

Title: Control apparatus for resetting pattern drums
IPC: D04B15/66
Filed: 1971-11-13
Abstract: A pattern control device and a plurality of actuator devices are mounted on the needle cylinder of a circular knitting machine and successively pass a stationary setting device which is moved to different setting positions under the control of a pattern chain cylinder. In different setting positions, the pattern control device and the actuator devices selectively operative for shifting pattern drums and a counter wheel. The pattern drums have a predetermined number of rows of pins to which alternating recesses and projections of the counter wheel correspond, except that one projection is replaced by a special deep recess which represents the initial position of the counter wheel and of the pattern drums. When a pattern has been completed, the setting means render all actuating devices operative to shift the pattern drums with the counter wheel in double steps to the initial position until the deep recess is sensed by sensing means which place the setting device in its initial positions in which the pattern control device and all actuator devices are rendered inoperative. In order to obtain the resetting of the pattern drums during one revolution of the needle cylinder, the number of actuating devices is an integer fraction of the number of rows of pins on the pattern drums, and the actuator devices shift the pattern drums a number of angular steps which is equal to the denominator of the fraction, for example, two steps at a time.

Title: Appts. for determining bilirubin concn. in human blood - gives rapid direct reading from completely automatic photometric system
IPC: G01N21/31
Filed: 1978-04-28
Abstract: A beam of light is directed through a sample of the serum towards a photoelectric detector with amplified, logarithmic output. A mobile mounting carries two optical lifters for passing different selected wavelengths and is actuated to insert the filters alternately and cyclically in the beam between the sample and the detector. Each time the mounting inserts a filter in the light beam a synchromised signal generator switches a comparing circuit to accept the detector pulse associated with the pulse of energy received via that filter. After two successive pulses via different filters the comparing circuit, which is equipped with memory element, delivers an output signal which is proportional to the difference between these two pulses. The output signal is passed to an indicating instrument providing a direct reading of bilirubin concn. in the sample. The appts. is completely automatic and can be used by non-specialists. Precise results are obtainable almost instantly.
