Title: Mechanism providing selectively intermittent mechanical oscillations
Inventor: MASON FREDERICK PERCIVAL
IPC: F16H35/00
Filed: 1966-07-29
Abstract: 1,118,357. Linkwork. CREED & CO. Ltd. 29 July, 1966, No. 34209/66. Heading F2K. An output member 16 is oscillated each time a control member 12 is displaced, power being derived from a continuously rotating input shaft 17. The mechanism is applicable to the carriage return of an electric typewriter or teleprinter. In Fig. 1, levers 1, 2, pivoted about an axis 3, loosely carry a transverse bar 4 to which is pivoted a link 11 connected by a tension spring 14 to a control member 12. Each lever has a latching bar 7, 8 pivoted about an axis 18 and spring-urged towards shoulders 10 on the levers 1, 2 and cams 21, 22 on the shaft 17. A force 19 uges the output member 16 into engagement with the latch bars 7, 8. With the levers 1, 2 in their first positions, as shown, the cams engage the latch bars only for a small part of each revolution to lift each bar in turn clear of its lever, the bars resting on the shoulders 10 of levers 1, 2 for the rest of the time. When the control member 12 is moved rightwards, whichever lever is not latched is moved to its second position at which point the link 11 engages a stop 15 and the spring 14 is unloaded so that the levers are stable even when the one not moved is released by its latch bar. The latch bar of the deflected lever is now free to follow its cam fully, causing an oscillation of the output member 16. When the latch bar is again in its highest position the control member 12, and hence the deflected lever, are moved back to their first positions. The phase relation between the input shaft 17 and output member 16 depends upon which of levers 1, 2 is deflected. The input shaft is driven by a rotary drive via a reduction gear giving a whole number reduction ratio so that an oscillation of the output member takes more than one revolution of the rotary drive. In a modification, Fig. 4, for use when a control impulse is applied to the control member 12, a latch 25 is urged into engagement with a projection 28 of the member 12 to hold it in the deflected position after the impulse. The movement of an unlatched lever to its second position deflects the latch 25 as the link 11 reaches the stop 15. In Fig. 6 (not shown), three levers, latch bars, and cams are used, a second transverse bar (34) being pivoted intermediate its ends to the link (11), and pivoted at one end to a link (33) pivoted to the first transverse bar (4) between levers (1, 2) and at the other end to a link (32) pivoted to the third lever (30). The stop (15) allows full deflections of one lever with the other two in their first positions.

Title: Battery charging methods and apparatus
IPC: H02J7/00
Filed: 1975-08-20
Abstract: 1509049 Charging batteries WESTING- HOUSE BRAKE & SIGNAL CO Ltd 14 July 1976 [20 Aug 1975] 34550/75 Heading H2H A method of charging a battery comprises the steps of passing a charging current through the battery, making a first measurement of the battery voltage during an interruption of the charging current, making a second measurement of the battery voltage during recommencement of charging, repeating the first and second measurements, comparing the last taken first and second measurements with the previous first and second measurements to determine respective increments thereof and repeating the steps until both respective increments are below respective predetermined values. The battery which may be a lead-acid traction battery, receives a preliminary charge for a seven minute period before the charging current is interrupted for a period of from five to seven seconds. At a predetermined time, for example four seconds after the start of the interruption the battery voltage is sampled and stored. At the end of the interruption, the charging current is restored for a period of from five to seven minutes and at a predetermined time in this period the battery voltage is again sampled and stored. The process of interrupting and restoring the charging current is then repeated, the battery voltage being sampled and stored during each interruption and charge period. A voltage comparator determines the successive voltage movements for the interruption and charge periods. An increment comparator determines when the voltage increments during the charge interruption periods have fallen below a predetermined value, thereby indicating the gassing point of the battery. The battery charging current is then reduced to a lower level to prevent damage to the battery and the charge interruption periods followed by charging periods continue until the voltage increments during the charging periods fall below a predetermined value. The battery is now fully charged and the charging current is terminated.

Abstract: 982,087. Valves. NEW YORK AIR BRAKE CO. Sept. 3, 1963 [Dec. 28, 1962], No. 34811/63. Heading F2V. With the spool valve 17 in the spring-centred neutral position shown, the pump 41 is connected to a tank 43 by way of inlet port 2, passage 13, annular grooves 7, 9, plunger grooves 18, 19, annular groove 8 and exhaust port 3 whilst annular motor grooves 6, 11, connected to the top and bottom of the motor cylinder 45, are isolated by spool lands 21, 23 whereby the motor is hydraulically locked. The spool is moved to the left to raise a load W connected to the motor 45, in which position of the spool pressure fluid flows to the rod end of the motor via passage 13, annular groove 9, radial spool passages 32, and groove 11. Fluid exhausting from the head end of the motor to the tank 43 passes through groove 6, radial spool passages 29, spool bore 24, a check valve 31, radial spool passages 28, an annular groove 5 and exhaust manifold 14. The spool is moved to the right to lower the load W, in which position fluid is transmitted to the head end of the motor 45 by passage 13, groove 7, passages 29, check valve 31, passages 28 and groove 6. Fluid displaced from the rod end of the motor flows to groove 11, and, if the pump can supply the demand of the motor, via radial spool passages 33, a check valve 34, passages 32 and an annular groove 12 to the tank; if the load W tends to move the motor at a rate that exceeds the supply capacity of the pump then the check valve 34 partially or completely closes so that some or all of the fluid displaced from the rod end is directed to the head end through an extension 15 of groove 11, radial spool passages 39, undercut 37 and groove 9 so forming a regenerative flow path. The weight W may be oppositely disposed so as to tend to retract the motor. Check valve 34, which is more heavily loaded than the other valve 31, also serves to prevent falling of the load when the pump is building up to operating pressure. The spool is provided with conical undercuts 36, 37 and radial passages 38, 39 to reduce the axial components of the dynamic reaction forces acting thereon; the undercut 37 and passage 39 also form part of the regenerative flow path. A relief valve 16 is associated with the supply passage 13. Specification 812,490 is referred to.

Abstract: 995,128. Raising liquids by heating. ENGLISH ELECTRIC CO. Ltd. Oct. 5, 1961 [Oct. 12, 1960], No. 34886/60. Heading F1R. [Also in Division F4] A fluid circulating system includes pressure vessels 15, 16, 17 which discharge in sequence into a line 10 and so into the system, the tanks being replenished with liquid from a tank 19 into which condensate from the system is discharged. When a vessel, say the vessel 15, becomes filled with liquid the pressure therein rises owing to the heating effect of coils 14. The liquid eventually boils and the vapour produced displaces an equal volume of liquid through the valve 23a into the line 10. The consequent reduction in pressure in the vessel allows valve 22c to be closed by differential pressure in the vessels 15, 17 thus allowing a pressure build-up and subsequent liquid discharge into the system from vessel 17. Discharge of vessel 17 results in the closure of valve 22b and permits pressure build-up and eventual liquid discharge from vessel 16. Discharge of liquid from vessel 16 results in the closure of valve 22a allowing pressure build-up and eventual liquid discharge from vessel 15 as before. Hence the valves 22a, b and c are operated in sequence by the respective vessels 16, 17, 15.

Each set of levers 56, 58 is actuated by means of inflatable bags 66, 68 located on either side of the arm 62 such that inflation of bag 66 causes outward movement of the arm 64 to a brick release position, whereas inflation of bag 68 causes deflation of bag 66 and movement of the arm 64 to a brick gripping position. The lower gripper members 20 each consist of a gripper plate 76 mounted at the end of the piston of an air cylinder 74 mounted in an arm 72 of the head 16. The number and positions of the plates 76 corresponds to the number and location of the bricks, e.g. bricks 3, 4, 8, 9 in the lower layer which are to be removed thereby. Thus in the position of the pick-up head 16 over the table 22, only the air cylinders 74- are actuated to release the bricks taken from the lower layer at position A, the upper gripper members 18 retaining the upper layer of bricks until the pick-up head 16 is moved to the position B.
