Title: Tone-generator circuits
Inventor: CROWTHER GERALD OFFLEY
IPC: H03K3/78
Filed: 1961-12-18
Abstract: 921,680. Ringing tone generators. MULLARD Ltd. Dec. 18, 1961, No. 45250/61. Class 40 (4). A ringing tone generator circuit comprises a pulse generator arranged to frequency-divide an A.C. source, e.g. 50 c.p.s. mains supply, to produce pulses at a frequency less than that of the source, e.g. 25 c.p.s., which are used to trigger a cold-cathode tube whose anode and cathode are connected in series with a load impedance across the A.C. source so that pulses of current flow from the source through the load on selected, e.g. alternate, cycles of the A.C. source. Fig. 1 shows one embodiment in which a cold-cathode tube TC is connected as a selfextinguishing pulse generator the time constant of R4, C3, C4 being arranged so that the tube is synchronized by a 50 c.p.s. waveform applied over transformer S to generate pulses at 25 p.p.s. Tubes TA and TB form a coldcathode multivibrator oscillating with a time pattern such as to indicate e.g. " busy " or " ringing " and the output of the multivibrator, added to the 50 c.p.s. supply at transformer S, switches the pulse generator TC. The output of the pulse generator, limited by diode Q 1 is applied to the trigger electrode of a cold-cathode tube TJ, Fig. 2, in the subscriber's line equipment which may be of the type described in Specification 913,617. When the called subscriber's speech tube Z, Fig. 2, is ignited, current flows in R8 and R9 and provides a biasing voltage to allow tube TJ to fire on receipt of a pulse from the ringing generator on its trigger electrode. The resulting pulses appearing across R10 are applied to the transformer U and hence to the called subscriber over line J and back to the calling subscriber through the speech tube Z. In an alternative form of generator, Fig. 7, a multivibrator TD, TE oscillates at 25 c.p.s. synchronized by the 50 c/s. supply applied over transformer S and gated by multivibrator TA, TB, generating the "ring- ing " pattern. Cold-cathode tube TC is selfoscillating at about 250 c.p.s. and is switched on and off by the output from the 25 c.p.s. multivibrator TD, TE, so that the signal output from tube TC comprises bursts of 250 p.p.s. at a repetition rate of 25 c.p.s., modulated by the appropriate " ringing " time pattern. These pulses are limited by diode Q1 and applied to the subscriber's line apparatus as described above with respect to Fig. 2. It is stated that the bursts of pulses generated by the embodiment of Fig. 7 offers a greater margin of stability in the triggering of the cold-cathode tube in the subscriber's line apparatus. It is suggested that the " ringing " time pattern could be generated by cam-operated switches.

Title: Improvements in booster-assisted actuated systems
Inventor: SADLER FRANCIS ANTONY DAWSON
IPC: B60T13/24
Filed: 1959-06-13
Abstract: 941,325. Fluid pressure brakes. GIRLING Ltd. June 7, 1960 [June 13, 1959; Sept. 5, 1959], Nos. 45267/62. Divided out of 941,324 and 45268/59. Headings F2E and F2F. In a fluid-operated booster, particularly for vehicle braking systems, the auxiliary force applied by the booster 6 is exerted through the medium of a piston rod 5 connected to a piston 19 and the admission of the operating fluid is controlled by valves (17, 20) mounted in the piston 19, the valves (17, 20) being operated by a push rod member 13 arranged so that movement of the latter member in one direction results in movement of the piston rod 5 in the opposite direction. In the embodiment shown in Fig. 1, a first lever 1 is formed by a brake pedal lever and is associated with a second lever 2 pivoted at 3 and urged into an anti-clockwise direction by a spring 4. The free end of the lever 2 is pivoted to the end of the piston rod 5 of the booster cylinder 6. The upper end of the cylinder 6 is open to a source of vacuum and a valve assembly 14 (Fig. 2) is mounted in the piston 19 of the booster 6. The valve assembly 14 is controlled by means of a push rod 13 actuated by a rocking arm 12 pivoted to the second lever 2. When the valves 17, 20 are in the positions shown in Fig. 2 the space below the piston 19 is in communication with the space above the piston and the piston 19 is urged to its lowermost position. When the lever 1 is urged in a clockwise direction it turns about a pin 9 mounted on the lever 1 by a small amount limited by the clearance between a slot 8 and a pin 7. This movement is enough to cause a pin 11 to move upwards away from the right-hand end of the rocking arm 12, allowing the lefthand end of that arm to move downwards resulting in downward movement of the push rod 13 under the action of a spring 18 in the valve assembly 14. As the push rod 13 is lowered, the valve 20 is closed to cut off communication between the two sides of-the piston 19 and then the valve head 16 moves away from its seating 17 to allow atmospheric pressure to pass through passages 16a and 14a into the lower part of the cylinder 6 to move the piston 19 upwards causing the piston rod 5 to move upwards and turn lever 2 about its pivot 3. Thus downward movement of the rod 13 results in upward movement of the rod 5 and the movement of the lever 2 augments the input force applied to the lever 1 to amplify the output force applied through a rod 24 to an hydraulic master cylinder 25. Movement of the lever 2 rocks the arm 12 back to its original position in relation to the lever 2, cutting off the booster. Should the booster fail, the brake pedal lever 1 can act on the rod 24 without having to move the piston rod 5 and the lever 1 turns about the axis of the pin 7 to substantially reduce the pedal load.

Title: A process for the production of hydrogen peroxide
IPC: C08G63/82
Filed: 1961-12-22
Abstract: Hydrogen peroxide is produced from a reducible-oxidizable polymer having anthraquinone groups by cyclically reducing and then oxidizing the polymer by means of air or oxygen in the presence of a solvent for hydrogen peroxide.  Specified polymers are polyvinyl anthraquinones, polyanthraquinonyl - methylene-malonates of linear polyalcohols having alcohol groups at each end, and acetals of formyl-2-anthraquinones and polyvinyl alcohols or acetates (see Specifications 965,676 and 965,677).  They are preferably in the form of spheres, plates or strips and are reduced catalytically, e.g. palladium on alumina, or by aqueous reducing agents, e.g. titanium trichloride in hydrochloric acid, and sodium hydrosulphite.  The re-oxidation may be achieved in the presence of a hydrogen peroxide stabilizer, e.g. sodium metaphosphate.  An apparatus is described in which the polymer is held in a vertical tube through the top of which is introduced, in an inert atmosphere, the aqueous reducing agent. The resin is washed in an ascending current of water and air or oxygen is then blown up through the tube.  The hydrogen peroxide is recovered as an aqueous solution by washing the resin. The reactions may also be effected on the polymers dissolved in a solvent, e.g. dimethyl formamide for catalytic hydrogenation, either alone or with aqueous alkali. After oxidation, the resin precipitates on dilution with water.

Filed: 1971-10-05
Abstract: 1356335 Yarn winding apparatus JOHNSMANVILLE CORP 5 Oct 1971 [26 Oct 1970] 46185/71 Heading D1J A machine, Fig. 2, for winding strand 16 onto a mandrel 28 is characterized in that it has a strand guide 22 spaced from the peripheral surface of the package and a fluid operated piston and cylinder unit 68, 90, Fig. 3, for moving the strand guide 22 away from the package axis as the package grows, the piston and cylinder unit 68, 90 being controlled by a clamping device 94 so as to maintain the strand guide in a predetermined spatial relationship with the peripheral surface of the package. The clamping device 94, Fig. 3, includes an adjustable needle valve assembly 120 and a spring loaded balance cylinder 122, and adjustably controls the time taken for the piston 90 to perform one stroke.  As the piston 90 is forced outwardly of its cylinder 68 it causes a cam follower 84 to roll in an inclined groove 78 on a bar 66 pivoted at 70. This causes the bar 66 to rock and it is this rocking movement that is conveyed by a linkage system 54 to the strand guide 22 that is rockable about a shaft 42. The inclination of the groove 78 is variable to vary the amount by which the strand guide 22 is moved by one stroke of the piston 90. Traverse Butterfly guides 32, Fig. 1, are rotated by an axle 36. The guides 32 and axle 36 constitute the foresaid strand guide 22. The mandrels 28 are traversed by a movable frame 30 operated by a cylinder (not shown). Proper co-ordination of the movement of the mandrels 28 mounted on the movable frame 30 with the movement imparted to the strands 16 by the traverse mechanism 32 causes the strand to be wound in a regular pattern. One of the pattern contours obtainable is illustrated in phantom in Figure 1 where the ends 34 of the packages are tapered.

Abstract: 1371772 Electric control of movement BALLY Mfg CORP 29 Sept 1971 [29 Sept 1970] 46322/70 Heading G3N [Also in Divisions A6 and G4] An amusement machine, which may be coinfreed, includes a control circuit comprising a rotary probability switch having a plurality of stationary contacts 50A-50G etc. and a travelling contact 50 which is stepped round continuously after the initiation of a machine cycle until one of a plurality of selection switches 41A-41F is operated, whereupon the travelling contact is stopped to connect one of the stationary contacts with a power source 56. The operation of a selection switch also serves to connect one stationary contact 45A-45F, 46A-46F in each angularly spaced set of contacts (I, II for example) in the contact field of a search switch to the other side of the power source. The travelling contactor of the search switch, which has portions 55A-55F connected to the stationary contacts 50A-50F of the probability switch, is then stepped round until it finds a live search contact in a suitable position to complete a circuit with the live probability contact, and is then stopped. On setting up of the complete search circuit pulse switches P-25 to P-17 each with a different pulse rate, are operated to supply pulses via the contacts in the particular set of search contacts at which the travelling contactor of the search switch has stopped, to respective clutch coils 20A-20F each associated with a respective pawl 19 that controls the movement of a racing figure 10. Each figure is attached to a drive chain 13 trained over a sprocket 14 mounted freely on a common motor driven shaft 15 (see also Fig.2 not shown), and rotated by a slip clutch (16) when the pawl 19 is withdrawn from blocking engagement with a control disc 18. The figure associated with the clutch coil that is connected to the pulsing switch with the greatest pulse rate i.e. P-25 is therefore moved faster than the other figures and is the first to operate a finish switch 100A-100F. The winning figure is thus determined firstly by the position in which the probability switch contactor stops and secondly by the way that the clutch coils and selection switches are connected to the sets of stationary search contacts. The sequence of operation of the machine is controlled by a control motor 35 and control cam switches I to VII. The circuit of Fig.3, is shown in more detail in Fig.5 (not shown). An award pay-out circuit, Fig.4 (not shown), determines whether the figures selected by operation of a selection switch is the winner of a race and pays out a prize or otherwise registers an award appropriately. Prizes may also be payed for second and third places in the race.
