Title: Method of determining the speed of rotating bodies
IPC: G01P3/44
Filed: 1973-03-20
Abstract: 1417739 Photo-electric movement of speed KERNFORSCHUNG mbH GES FUR 20 March 1973 [27 March 1972] 13201/73 Heading G1A The speed of rotation of rotating bodies, e.g. rollers or balls supported in a bearing, is determined by providing at least one of the bodies with a radiation emitting point on its surface, a shield having a gap either being separately provided or being provided by the bearing so that at least part of the bodies is shielded from a radiation detector 15 arranged to receive radiation from the radiation emitting point through the gap, the detector providing sequences of signals, the cycling time between succesive sequences being determined. As shown in Fig. 1 one roller 7 has a radiation emitting point 10 on its face 9, a shield consisting of an outer ring 11 and a disc 12 providing a gap 13 filled with transparent material being provided. The disc 12 may be omitted. As described, the point 10 emits gamma rays and the shield is a lead collimator. Alternatively, the point may emit alpha or beta rays in which case the shield is omitted and the bearing provides the shield. The point may alternatively emit neutrons. The detector 15 may be a sodium iodide scintillation crystal with a photo-multiplier. As shown in Fig. 3, the output pulses of the detector are amplified at 21 and provided to a discriminator 22 (which may be omitted). The output of the discriminator is fed to a filter 23 whose output is applied to an oscilloscope and a trigger 26. A counter 27 and a printer 28 complete the circuit.

Title: Glass pressing plunger and method of its use
IPC: C03B35/00
Filed: 1963-04-03
Abstract: <PICT:0972622/C1/1> <PICT:0972622/C1/2> In an apparatus for press moulding glass articles, a pressing plunger 21 is movable into or out of pressing relation with a charge of material 40 in a mould 12, there being means encircling the plunger 21 to embody in it a vacuum chuck for maintaining a pressed article in engagement with the plunger during its movement out of co-operative relation with the mould.  The means encircling the plunger 21 comprises a ring 22 suspended from a fluid operated hanger 24 which is axially movable with respect to the plunger, said ring 22 having a channel 23 which together with the plunger forms an annular vacuum chamber 25 connected to a region 26 of larger bore of ring 22.  A passage 29 in the plunger 21 is connected through valve 30, chamber 41 and spool valve 35 to a vacuum.  In the pressing operation the ring 22, at its lowest position, engages the mould before the entry of the plunger. On completing the pressing operation the plunger forces glass into the bore 26 of the ring.  The spool 36 of valve 35 then moves to create vacuum in chamber 41 at the upper end of hanger 24 causing it to raise the ring 22, vacuum also being created in cavity 25 and bore 26 via passage 29, thus causing the blank to adhere to the plunger. The article and plunger are then withdrawn from the mould, and the article stripped from the plunger by moving the spool 36 of valve 35 so as to create a pressure in chamber 41 and push the hanger 24 downwardly.

In a method of taking up the slack of flexible power-supply cables 30, Fig. 3, connected between a fixed point 32 and a telescopic mast 14 of a loadlifting truck, the cables are guided over a pulley 37 which is guided as at 33 while held by a tensioning cable 41 passing over the pulley 37 from below and connected between fixed and movable points 42, 43. In the example, the cables 30 are connected to a lifting carriage 15 for operation of a side-shifting attachment (46), Fig. 1 (not shown), the carriage 15 being supported and moved by chains (28), Fig. 2 (not shown), passing over pulleys (27) at the head of an hydraulic ram sleeve (24). The cables 30 pass over a further pulley 35 mounted on a common axis with the chain pulley (27) so that on initial movement of the carriage 15 the slack is taken up by movement of the pulley 35 moving at half the speed of the carriage. On extension of the telescopic mast 14 by ram 19, after the carriage 15 has reached the top of the mast 14, the pulley 37 moves up at half the speed of the mast 14 and carriage 15.

Title: Improvements in systems for the automatic tuning of radio transmitters or receivers
IPC: H03J7/16
Filed: 1955-05-12
Abstract: 808,974. Radio transmitting and receiver tuning apparatus. MERLES, A. J. May 12, 1955 [May 18, 1954], No. 13714/55. Class 40 (5). An output circuit 14 of a transmitter or of a receiver local oscillator automatically tuned to a selected frequency F of an oscillator 11 by sweeping the tuning through a range of values by a motor driving a variable capacitor 15 or inductance of the circuit until, due to the frequency changing action of an oscillator 10 mixing its oscillations of frequency f with those of the oscillator 11, the circuit resonates at the frequency F -f (or F+f) whereupon a relay 70 is energized to slow down the motor and the oscillator 10 is rendered inoperative as by its H.T. supply being disconnected. The next resonance, at frequency F, then stops the motor. On changing the selected frequency of oscillator 11, the variable tuning element 15 is always returned to a starting position at high speed, followed by high-speed drive to the frequency F - f (or F+f). As shown, the motor 27 drives the tuning capacitor 15 through a change-speed gear-box 23 and cam 20. On changing the selected frequency, the tube 12 and relay 70 are no longer energized, with the result that brake control relay 50 which was previously energized to brake the motor 27 through solenoid 32 and brake 30, 31, assumes rest position and consequently motor drive reversing relay 60 and speed changing relay 40 are also at rest position. The motor 27 is therefore driven at high speed in direction X of cam 20 till " starting position " is reached by the cam closing contact 21 whereupon relay 60 is energized (and remains so by a holding contact) and the motor drive reversed. Moreover, only after the reversal of drive due to relay 60 being energized and contacts 65, 66 closing, is the speed change relay 40 prepared for energization, i.e. the closing of contacts 71, 72 of relay 70 on resonance at frequency F - f only then energizes the relay 40. The relay 80 with capacitor 109 delays the energization of brake control relay 50 and is operated only after operation of relay 40, i.e. speed change through contacts 46, 47 when, on closing of contacts 73, 71 of relay 70, the frequency F is reached. Alternatively the valve 12 and relay 70 may be responsive to a frequency discriminator output derived by beating the oscillator 11 and a further oscillator of frequency (F - f ) or (F + f ) controlled from the tuned circuit 13. The relays may also be replaced by gaseous discharge tubes.

[Also in Group XXX] The spreading mechanism of a manure spreader is provided with automatically operating control means for disengaging the drive to an endless conveyer when the speed of the spreading mechanism falls below a certain value. As shown the spreading mechanism is driven from a tractor power shaft and the conveyer is driven from the ground wheels of the machine by means of a cam 18 which operates a pawl 30 and ratchet wheel 28 and gives an intermittent movement to the conveyer 15. The conveyer drive is disconnected by means of a centrifugal device 40 mounted on the drive shaft 10 and comprising two fly-weights 42 pivoted on a collar 41, the weights moving a sleeve 50, by centrifugal force, to place the pawl 30 into contact with the ratchet 28 by means of a bell crank lever 58 and link 63. The pawl 30 is held out of contact with the ratchet 28 until the driving shaft 10 has reached a pre-determined speed.

Abstract: 329,812. Lorenz Akt.-Ges., C. Jan. 10, 1929, [Convention date]. Bearings, determining; directive signalling.- A system for enabling ships to navigate a harbour, or to assist aircraft to fly over a predetermined course, is characterized by the use of a series of directive wireless aerials and reflectors transmitting waves of less than 10 metres, and installed at a height above the earths surface equal to the square of the desired range of transmission divided by twice the radius of the earth. Thus for a range of 20 Miometres the transmitters should be arranged at a height of 33 metres. As shown in Fig. 4, a ship 1 once within the range of the transmitter HS is warned by short-wave transmitters S1 - - S7 of the presence of the line of coast shallows and by a transmitter S8 of a seaward rock or shoal. A short-wave beam transmitter RS1 gives the final line of approach into the harbour. Another ship 2 may be given the course indicated by a short-wave transmitter RS2 until it reaches the beam radiated by transmitter RS1, whereupon it turns into the final course. The transmitting apparatus used is of the kind described in Specifications 330,750 and 338,028.
