Filed: 1970-12-18
Abstract: 1323484 Dynamo-electric machines H BEYERSDORF 18 Dec 1970 [29 Dec 1969] 60128/70 Heading H2A A planar air gap dynamo-electric machine comprises a discoidal rotor 11 axially dispersed between two stators 21, 22, the rotor being toothed on both its axial sides, the stators carrying approximately radially extending A.C. windings 13, 14 and also each carrying an annular energizing winding 18, 19 disposed between the respective working air gap and an auxiliary air gap 23, 24 located radially within the working gap. The A.C. windings may be single- or poly-phase and are located in slots in laminated stator portions 15, 16. The rotor teeth may be substantially radial, Fig. 3 (not shown) or of curved formation, Fig. 5 (not shown) to reduce the harmonic content of the current in the A.C. windings. Instead of taking the form shown, the auxiliary air gaps may be cylindrical or radial; in the latter ease, Fig. 6 (not shown) the rotor includes a non-magnetic barrier (34) to prevent flux short-circuiting and consequent asymmetric magnetic attraction on the rotor. A cooling system for the rotor and windings is depicted in Fig. 7 (not shown). The air flowing over the rotor and windings is passed through a heat exchanger on one of the stators wherein it is cooled by liquid, e.g. water. The rotor and stator may be made of sintered or bonded ferrite material at least in the region of the working air gaps and the rotor may comprise a hub portion of coiled metal strip. The machine may operate as a generator or motor.

An operating mechanism 43 is coupled to the exhaust valve 37 of the interrupter units 7 by a linkage 45 which passes through the limbs of the bifurcated housings 9 mounted on top of each column.
Patent GB-655849-A (GB)
Abstract: 655,849. Calculating-apparatus. ESACTA, SOC. R. L. March 30, 1948, No. 9000. Convention date, April 1, 1947. [Class 106 (i)] The invention relates to a calculating-machine provided with item-entering members in the form of drums having radially-movable teeth, each drum comprising a pair of discs 20-21 separated by a spacer member 22 and mounted on a main driving- shaft 12. A washer 23 is combined with the spacer member 22, the periphery of the washer 23 acting as supporting pivot for a movable disc 24 having a shaped slot thereon in which slot may engage projections 26 laterally carried by a set of radially movable teeth 28. There are nine teeth in each set, each tooth having a pair of latches 29 which engage in relative slots 30 radially formed in one portion of the disc 21 to act as a guide and a stop for the teeth. Rings 34 and 35 are arranged on the disc 20 to support a movable disc 36 which forms the setting lever driving the teeth 28. The ring 35 serves as a guide for the lever 26. At the outer side of the disc 21 there is a locking-ring 40 provided with threaded holes in which screws 41 are engaged passing through rings 34, 35, 22, 23, and the discs 21, locking them in a single unit in the form of a drum mounted on shaft 12 and keyed by a key 42. In order to maintain the setting lever in a predetermined position it has in a suitable peripheric point teeth 44, Fig. 4, with which a spring-operated pawl 45 is engaged and is pivoted laterally to the disc 20. The setting lever also has teeth 46 meshing via an intermediate toothed wheel 47, Fig. 2, with a pinion 48 driving a numeral drum 49 in the item entering indicator C. The shaft on which the item entering members B are mounted is provided with an operating crank of known type. By acting on the setting levers 36 one or more of the movable teeth 28 is caused to project from discs 20 and 22. The rotation angle of the item indicator C will correspond to the magnitude of the set number. The operation of the crank 85 renders the locking means effective and the rotation of the selective drums is caused in one direction or in the opposite one according to the operation made in such a manner that the protruding teeth 28 engaging the teeth of the respective intermediate toothed wheels 62 cause the numeral drums D to rotate the required amount. By operating the shaft 99 by means of the lever 100 both the item-entering members B and the numeral members 49 of the item entering indicator C are zeroized.

Patent GB-2022816-A (GB)
Title: Instrument for Measuring the Sizes and Quantity of Particles in a Fluid Medium
IPC: G01N15/10
Filed: 1978-06-09
Abstract: An instrument is arranged to categorise by size particles in a fluid medium such as air and to count the number of particles in each size category. Particle size is measured as a function of the intensity of light scattered by each particle, the scattered light being directed to a photo-electric detector (4) whose output is connected to a number of threshold devices (11) which determine the appropriate size category. To minimise measurement errors due to instrument parameters which may vary during use, a continual calibration by the repeated simulation of a reference particle is effected by means of oscillating rod (6) or a chopped reference path, the corresponding photo-detector output being attracted by a circuit (10) to generate a reference against which the threshold devices (11) are set. The instrument can be used to measure atmospheric pollution, or medical samples. <IMAGE>

The propeller shaft 5 is journalled in a bush 36 with a slightly oblique bore so that by rotation of the bush through 180 DEG  the angle of inclination of the shaft can be adjusted. <IMAGE>
Patent GB-2013911-A (GB)
Title: Photographic camera with exposure meter
IPC: G03B17/18
Filed: 1979-01-31
Abstract: A light-sensitive element 3 produces at its point of connection to a resistor 4 an output voltage, a differential amplifier 7 compares this output voltage with a first reference voltage produced at the connection point between two resistors 9 and 10, and a further differential amplifier 8 compared the output voltage with a second reference voltage produced at the connection point between the resistor 10 and a further resistor 11. When conditions for over exposure exist, the output voltage is more positive than the first reference voltage, and the amplifier 8 energises a light-emitting diode 21 by way of a constant current source 17. When conditions for under exposure exist, the output voltage is more negative than the second reference voltage, and the amplifier 7 energises a light- emitting diode 16 by way of a constant current source 12. When correct exposure conditions exist, the output voltage lies in the range defined between the first and second reference voltages, and both light-emitting diodes 16 and 21 are energised. This range can be adjusted to take account of the exposure latitude of the film to be used by adjusting the value of the resistor 10. A wedge 22 (or diaphragm) is adjustable according to set shutter or aperture value. A resistor 5 is switched in or out according to film speed. <IMAGE>

Title: Fluid Flow Measurement
IPC: G01F5/00
Filed: 1979-02-21
Abstract: A device (10) for diverting a relatively small but representative flow sample out of a large diameter conduit (12), through a flow meter (15), and back into the large diameter conduit comprises a generally flat body (11) extending diametrically across the conduit and having in its upstream face a narrow flow intake slot (16) whose length is substantially equal to the diameter of the conduit. A deflector plate (18) inside the body divides the flow sampled by the intake slot into two flow paths, which then recombine and lead into a meter inlet conduit (13) projecting exteriorly of the large diameter conduit. Fluid returns to the conduit via an orifice (24) disposed on the conduit axis. <IMAGE>
Patent GB-2017318-A (GB)
Title: Improvements in or relating to porometers
IPC: G01N15/08
Filed: 1979-04-09
Abstract: Porometers for measuring the size of stomatal apertures in biological specimens incorporate two arms 2, 3 pivoted to one another and formed with apertures 6, 14 capable of being brought into register. Permeable pads 10, 11, 12, 15 and 16 cover the apertures and the arm 2 supports a syringe in communication with the aperture 6 so that air can be drawn into the syringe through the pads by operation of the syringe. The instrument is used by gripping the specimen between the pads on the arms 2, 3 then pulling and releasing the plunger of the syringe, the difference between the two positions of the plunger before and after operation giving the desired information of stomatal area. <IMAGE>
