Abstract: 1,085,199. Measuring fluid-flow. B. T. HASELOCK and K. ORRIDGE. Sept. 2, 1966, No.39273/66. Heading G1R. In a device for comparing the gas flow rates through a particulate material, such as air through grain in a dryer, a bell collector 10 of circular cross-section is placed on the surface of the material 13 to collect gas passing therethrough, which gas passes into a transparent tube 16 and through a slot 20 to move a lightweight ball 17 to indicate the gas flow. The tube may be calibrated and provided with one or more slots 20 arranged in parallel and overlapping relationship. The device is positioned by spirit levels placed in or secured to a flat surface 11 at right angles to one another.

Title: Frequency multipliers
IPC: H03B19/00
Filed: 1971-08-26
Abstract: 1357145 Frequency multiplication SIEMENS AG 26 Aug 1971 [24 Sept 1970] 40006/71 Heading H2F A frequency multiplier arrangement comprises a plurality of stages A, B ... with differing multiplication factors connected to a common generator (not shown) producing a single fundamental frequency, each stage having its input connected via a respective switching diode SD1, 8D2 ... to the generator output, any given one of the stages being rendered operative by a connection which causes the supply for the generator to be supplied via the switching diode. As shown each multiplier stage includes a semiconductor diode D1, D2 ... and is supplied by a - 24 volt source on line L1 to apply a reverse bias to each switching diode SD1, SD2 via resistances R1, R2... and to each diode D1, D2 in the multiplier circuits via resistances R1, R11, R2, R12 ... The particular stage to be operative is selected by connecting the point, e.g. a in stage A between the 2 resistors R1, R11 to earth by a switch S. The diode SD1 is therefore rendered conductive and the reverse bias at D1 is reduced. Since the voltage drop across SD1 is very small, all other switching diodes are maintained off owing to the earth potential applied at their cathodes. Decoupling between the stages is effected firstly by a low-pass filter CT1, CT11, LT1 and by a detuning effect of the high reverse bias on diodes D2 ... which affects their capacitance. In a modification, Fig. 3 (not shown), this detuning is effected by the drawing of a high current in the pass direction through the diodes D2 ... in the non-operative stages, the - 24 volts being supplied to all stages through a common resistor (R1) and h.f. decoupling circuit to the anode of each switching diode and additionally through load resistors (R11) (R12)...to the cathodes of diodes D1, D2 ... The point between the resistors (R1) and, e.g. (R11) (for stage A) is earthed for the operative stage. The resistors (R1) (R11), &c. should be as small as possible to enable a large current to be drawn through the multiplication diodes in the non-operative stages but should be large enough to provide suitable load resistance for the bias of the diode of the operative stage. The compromise is obviated in a second modification, Fig. 4 (not shown), which comprises a load resistor (Ra) for each stage in parallel with a transistor circuit having - 24 volts applied to the emitter. If the earth potential is applied in the emitter circuit, the transistor is rendered non-conductive to form a high bias resistance for the multiplication diode whereas in the non-operative stages the transistor conducts and allows the high current to pass through the associated diodes.

Abstract: 1,140,282. Slip-casting. CERAMIC ENG. Ltd. 4 Sept., 1967 [8 Sept., 1966], No. 40162/66. Heading B5A. Each mould of a battery of moulds for slip casting, e.g. wash basins, comprises detachable parts 2, 3 with an inlet 8 for slip at its bottom and an outlet (15), Fig. 2, not shown, at its top whereby slip is fed, e.g. by a pump, continuously during a casting period through the mould from inlet to outlet. From the outlet the slip flows via a channel on the outside of the mould to a trough arranged parallel to the moulds. After the casting period the flow of slip is reversed to run off the excess, after which the flow is stopped to allow the article to set sufficiently to enable its removal from the mould. For the latter purpose the parts 2 and 3 are separated horizontally during which they run on rollers 6 on a bench 7, and the cast article is removed horizontally from the mould part 2. The parts 2 and 3 are attached to adjacent moulds; the moulds are tilted transversely towards their inlets.

Abstract: 1,103,232. Ratchet mechanism. CHANDLER EVANS Inc. 22. Sept., 1965, No. 40503/65. Heading F2Q. [Also in Divisions H1 and H2] In an electromagnetic stepping device, particularly for actuating hydraulic valves or switch contacts, a moving coil 1 in the field of a permanent magnet 2 co-operates with a ratchet mechanism so as to produce incremental motion of an output shaft in a direction dependent on the polarity of pulses fed to the moving coil 1. As described, a nylon cylinder 3 is supported by diaphragm 4 and carries the moving coil 1 and left- and right-hand nylon driving ratchets 6, 5 which are associated with left- and right-hand idler ratchets 9, 8 and left and right-hand driven ratchets 14, 13 attached to a rotary output shaft 12. The idler ratchets 9, 8, are biased towards the driving ratchets 6, 5 by means of springs 10, 11, oversized teeth 6a, 5a being provided to limit the relative movement between idler and driving ratchets. A detent ratchet 16 is prevented from rotation by pins 18 but is capable of being displaced to the right when torque is applied to the driven ratchets 14, 13 and returned by springs 17 so as to provide positive location positions. In Fig. 2 (not shown) the rotary motion of shaft 12 is reconverted by means of a ball screw device (34) into linear motion. The device is stated to be capable of operation at 400 pulses per second.
