Abstract: 1,228,220. Variable-ratio gears. ROBERT BOSCH G.m.b.H. 26 April, 1968 [27 April, 1967], No. 19785/68. Heading F2D. A constant mesh gear for an electric drill or like tool has gear-wheels selectively clutched to an output shaft by positive clutch means. As shown gear-wheels 101, 102 are selectively clutched to an output shaft 103 by a rockable key 106 which is mounted in an arcuately bottomed slot 105 in an actuating rod 104 and is retained axially with play by a pin 109. On shifting the rod 104 axially the key 106 is tilted to positively engage internal teeth in the selected gear-wheel 101 or 102. The rod 104 is shifted axially by a rotatable handle having an eccentric pin engaging a slot in a member which is guided for axial movement and which is provided with a fork engaging the rod 104. In a modification the gear-wheels are clutched to the output shaft by a radial pin which projects out of the axially slidable control rod, the internal teeth of the gear wheels stopping short of the adjacent faces of the wheels to provide a neutral position.

[Also in Disivions F2 and G3] A valve has a spring-loaded piston 12 controlling flow from an inlet 9<SP>1</SP> to an outlet 14 and actuated by fluid-pressure in a chamber 16. A spring-loaded spool valve 10 throttles the flow from chamber 16 on closing movement of the valve 12 in dependence upon the pressure at inlet 9<SP>1</SP>. The valve is used in a circuit between a pressure source and a motor M driving a winch drum D with a load W, and is opened by pressure in line 7 to connect the motor to exhaust 3 via lines 4, 6 when a control valve 1 is in a winch lowering position shown. When the control valve is moved to a winch stop central position the motor is driven by the load W to produce a pressure at port 9 dependent on the load which actuates the spool 10 to correspondingly throttle the outflow from chamber 16 to exhaust and allow the valve 12 to gradually close.

Abstract: 1,230,965. Ratchet mechanism. W. M. STEWART. 23 Feb., 1970 [9 May, 1969], No. 8506/70. Heading F2G. [Also in Divisions G4-G6] In a vending machine set to vend 15 cent articles, 5 and 10 cent coins are directed to slots 10 and 9 respectively, where they strike crank portions 48, 51 of rods 47, 50, causing them to rotate about shaft 46 with blocks 44, 45. This rotation causes dog 39, mounted in pivot 41 on block 43, to contact ratchet wheel 36 and rotate it clockwise by the width of two teeth. The smaller dog 38 rotates the wheel by one tooth width. Ratchet wheel 36 is biased counterclockwise towards its starting position, Fig. 5, by spring 33, but rotation in this direction is prevented by pawl 55, which is biased towards the wheel by spring (57, Fig. 1). After the wheel has recorded the insertion of at least 15 cents, pawl 55 is displaced by roller (54, Fig. 6) mounted by pin (53) on wheel 36. Shoulder 61 of pivoted arm 60 then engages flange 62 so that the pawl is held in its inoperative position whilst spring 33 rotates wheel 36 back to its initial position in which pin 67 presses against arm 73 of catch member 71, thereby both halting wheel 36 and freeing flange 62 so that the pawl can re-engage with the wheel. The wheel rotation produced by the insertion of 15 cents causes pin 65 on wheel 36 to depress blade 19 sufficiently to actuate switch 13 and thereby dispense the article. The greater rotation produced by the insertion of 20 cents depresses blade 19 sufficiently to depress arm 22 of blade 20, thereby actuating switch 18, so that 5 cents change is dispensed. The apparatus may be modified to dispense 10 cent articles by moving pin 67, Fig. 5, to the right-hand one of the four slots 66; whilst 20 and 25 cent articles can be dispensed by moving the pin one or two slots to the left respectively.

Addition to 1,184,643. Headings H3F and H4L. A frequency synthesizer having a range of positions at each of which a unique frequency pair is delivered comprises a lower order oscillator 1 selectively connectable-on the embodiment, by means of AND gates 10-19-to a first set of quartz crystals 00<SP>1</SP>-09<SP>1</SP> to provide a lower order frequency. It also comprises first and second higher order oscillators 2, 3 respectively, selectively connectable-in the embodiment, by means of AND gates 40-44 and 45- 49 respectively-to second and third sets of quartz crystals 00<SP>1</SP>-40<SP>1</SP> and 50<SP>1</SP>-90<SP>1</SP> respectively to provide second and third higher order frequencies. First and second summation elements, i.e. mixers 4, 5 respectively are used to combine the lower order frequency with both second and third higher order frequencies to provide first and second output frequencies respectively. Furthermore control circuitry 9 is provided adapted to control the selective connection of the first and second higher order oscillators to the second and third sets of quartz crystals so that for each selected first higher order frequency there is always selected a particular second higher order frequency. In the embodiment the control circuitry 9 also selects the lower order frequency. The output frequencies from mixers 4, 5 are applied to the respective inputs of switching arrangement 6: the lower output frequency is applied to output terminal 7 or 8, dependent on the state of switch 6, the higher frequency being applied to the other output terminal. In a transmitterreceiver station, the switch state depends on whether the station is making or awaiting a call, terminal 7 supplying the reception frequency and terminal 8 the transmission frequency.

Abstract: 1,233,227. D.C. supply systems; control of D.C. motors. ROBERT BOSCH G.m.b.H. 12 Sept., 1968 [13 Sept., 1967; 21 Oct., 1967], No. 43380/68. Headings H2H and H2J. A circuit for feeding a load 10 with a controllable direct current comprises a first thyristor 13 for conducting the load current, a second thyristor 14 for cutting off the first thyristor 13, a pulse generator 16 for firing thyristor 13, a pulse generator 17 for firing thyristor 14, and a common controller 22 e.g. a potentiometer as shown or a pair of separately controlled transistors, for controlling the separation of the firing pulses, the second pulse generator 17 being blocked whilst the first thyristor 13 is non- conducting. The load 10 may be a D.C. motor, D.C. magnet or as shown an eddy current brake of a motor vehicle. As shown, slider 23 of potentiometer 22, and switches 34 and 36 are all controlled by brake pedal 11. On depression of brake pedal 11 switch 34 is closed before switch 36 is opened so that relay 24 is energized to permit current to flow from battery 12 through coil 10, primary winding 27 of transformer 28, capacitor 15, resistor 35 and switch 36 to charge capacitor 15. Simultaneously a current flows from junction 30 to negative lead 29 through resistor 56, Zener diode 54, and resistor 55 to render transistor 52 conductive. The transistor 52 therefore by-passes capacitor 48 of pulse generator 17 and blocks the pulse generator. At the same time capacitor 43 of pulse generator 16 is exponentially charged through potentiometer 22 and resistor 44 thereby rendering path Em- B1 of unijunction transistor 18 abruptly conducting at a predetermined voltage. Thereupon the capacitor 43 discharges through transistor 18 and produces a firing pulse for thyristor 13. On conduction of thyristor 13 capacitor 15 is charged in the reverse sense through diode 32 and transformer secondary 33. The coil 10 now carries virtually the full battery voltage and the current therein increases exponentially. Because the potential at junction 30 and line 29 is now substantially the same the capacitor 43 can no longer be charged since it is by-passed by diode 51, and the transistor 52 no longer conducts since Zener diode 54 blocks the base current. Thus capacitor 48 is charged through resistor 45 and potentiometer 22 to render the unijunction transistor 19 conductive after a set time so that a triggering pulse flows through junction B1-Em of transistor 19 to fire thyristor 14. Capacitor 15 thereupon discharges through thyristors 13 and 14 to commutate thyristor 13. When thyristor 13 is switched off capacitor 15 is recharged, pulse generator 17 is blocked again in the manner previously described, and thyristor 14 is switched off. The capacitor 43 is charged again in the manner already described, and whilst thyristor 13 is blocked an induced exponentially decaying current from winding 10 flows through by-pass diode 26 to maintain the braking action. As the brake 11 is further depressed the length of time that thyristor 13 conducts is increased. The switch 36 may be replaced by a transistor timing circuit (Fig. 5, not shown).

Apparatus for determining the rate of uptake of radioactive cation by red blood cells comprises an elongate member 10, 11, 12 having a cation exchange resin 16 positioned within it and only at or towards one end of the member and fluid permeable means such as porous plate 16a for retaining the resin in position within the elongate member. The apparatus shown in Fig. 1 has inlet 13 for admission of a blood sample into part 11 and a source 15 of radioactive rubidium. The sample is incubated in contact with the source 15, the elongate member is twisted about joint 27 to an S-shape so that the blood sample contacts cation exchange resin to enable the resin to take up rubidium from the plasma (but not from the cells), the resin is washed free of blood and the rubidium on it determined by counting. In the embodiment of Fig. 3, elongate stick 18 has recessed end 19 within which is mounted radioactive cation source 21, apertured cover 22, recessed end 24 containing cation exchange resin 26, and fluid permeable cover 25 for the resin. In use, end 19 is immersed in the blood sample for incubation, the stick is inverted when the radioactive cation present in the sample is taken up by the resin, then the cation content of the resin is determined.

Abstract: 1,265,349. Testing gas bottles for leaks. COMPAGNIE DES GAZ DE PETROLE PRIMAGAZ. Nov. 17, 1969 [Feb. 21, 1969], No.56109/69. Heading G1S. A valve 4, Fig. 5, on top of a gas bottle 1 is checked for leaks by covering it with a cap 2 connected by a tube 13 to a gas detector 15, a vacuum pump 16, and a switch operating gas indicator 18. The cap 2 has a sealing ring 3 and an annular chamber 11, Fig. 2, communicating via holes 12 with the cap interior, and a compressed air connection 20 scavenges the cap and builds up a slight pressure therein to exclude the atmosphere surrounding the machine. In operation, a gas bottle 1, Figs. 1, 4, is carried by a constantly moving conveyer 8 to a check point where the bottle moves a contact 23, Fig. 5, and causes an air piston 24 to operate and hold the bottle still. The contact 23 also operates a valve 34 which supplies air to an electro-valve 19, so that when the gas indicator 18 is at rest air is also supplied to valves 36, 37 controlled by a timer 48. Valve 37 in turn controls a valve 38 so that when the contact 23 is moved by the bottle scavenging of the cap 2 by compressed air from line 21 is stopped and a double valve 39 is operated to lower a jack 6 and the cleaned cap 2 on to the bottle valve 4. If the bottle does not leak then the pump 16 and the gas detector 15 cannot pass leaking gas to the indicator 18 which therefore does not function and allows the valves 36, 37 and 39 to raise the jack 6 and cap 2 and retract the bottle holding piston 24. If the bottle does leak gas however then the indicator 18 moves and operates a switch to cut off the current supply to the electrovalve 19 which then supplies air to a conduit 50, Fig. 4, and also renders valve 37 inoperative. The jack 6 and cap 2 are then made to rise and release the bottle as before, but the air in conduit 50 has meanwhile charged a "memory" valve 41 which supplies a valve 42 connected to an ejector contact 28. As the released bottle continues on the conveyer 8 it moves the contact 28 which operates valves 42, 43 and an ejector piston 29, 30 which pushes the bottle on to a reject conveyer 27. The piston 29 also moves a contact 33 which actuates valve 44 and air line 45 to return the whole installation to a condition ready to receive another bottle.
