Title: Improvements in or relating to lifting jacks
IPC: B66F1/00
Filed: 1925-02-27
Abstract: 235,813. Powell, A. D. Feb. 27, 1925. Jacks.-In lever jacks of the kind in which the range is increased by ratchet mechanism, pawls are provided which are normally kept in contact with the ratchet by gravity &c. and are disengaged at predetermined positions to permit lowering. The crutch supporting member 8 is connected to the frame 1 by parallel links 9, 5, the inner end of the latter of which is provided with a ratchet. The forked ends 6 of an operating handle 7 are freely mounted on the shaft 4 of the ratchet lever 5. A pawl 13 mounted on the handle and a pawl 16 mounted on the frame 1 are normally maintained in engagement with the ratchet by weighted arms 14, 17 respectively. A spring 25 connects an arm on the pawl 13 with a slidable frame 21 which can be moved towards one end of the handle against the resistance of a spring 23 by a handle 18. A rod 27 connected to the pawl 16 is slidably mounted in a trunnion 26 carried by the frame 24. A spring 28 is mounted on the rod between the trunnion 26 and a plate 29 adjustably mounted on the rod. A pin 30 limits the upward movement of the arm 14, and a pin 31 guides the pawl 13 into the teeth of the ratchet.

Title: Improvements in or relating to windscreen wiper blades
IPC: B60S1/38

Abstract: 695,868. Windscreen cleaners. O'SHEI, W. E. June 6, 1951 [March 6, 1950], No. 5647/50. Class 138 (1). A windscreen wiper blade comprises a squeegee the back of which accommodates or carries backing means which at least part way along its length, is flexible in a direction normal to the surface of the windscreen and resists substantial flexing in a direction parallel to this surface, the wiping edge of the squeegee, at least at one of its free outer ends, being deeper than adjacent the centre of the wiping edge and being sufficiently thin and resilient to be able to fold over as the blade operates, whereby it conforms to surfaces which are flat or have a small curvature, partly by flexing of the backing means and partly by folding over of the wiping edge at the end or ends of the squeegee. The squeegee may comprise a moulded strip of rubber, its cross-section may e.g. be as described in Specification 666,473, and its edge may be deeper at one or both ends according to the type of windscreen than at its centre. The squeegee, when its back edge is straight may for example be formed with its wiping edge shaped to a large radius curve, preferably greater than the smallest radius of curvature of the windscreen. The resilient backing member may comprise a strip of metal fixed to the back of the squeegee in any suitable manner as by clipping. This member, is normally curved. The wiper arm is attached to a connector which may be fitted adjacent the centre of the back of the strip, or may be attached to the central portion of a bridge piece connected at its ends to two spaced points on the strip. In another construction two resilient metal strips are disposed at opposite sides of the squeegee element e.g. as described in Specification 666,473, but are normally curved. In this case, a bridge piece similar to that described in Specification 670,333 may be employed the ends of the bridge piece being shaped to embrace the outer edges of the strips. In a further construction the centred region of the squeegee may be fitted with a rigid backing with one or both end regions provided with a resilient backing normally curved. Where the blade is equipped with a bridge piece an aperture is preferably provided in the back thereof to receive the end of the wiper arm. The blade is preferably connected to the bridge piece, connector or wiper arm so as to adopt an inclined trailing position as the blade moves over the windscreen. Specifications 666,474, 679,540 and 683,201 also are referred to.

Filed: 1918-04-11
Abstract: 115,623. Montelius, C. O. J. March 24, 1917, [Convention date]. Systems of charging and discharging galvanic batteries.-Storage cells or polarization cells are charged in a primary circuit and discharged in a secondary circuit, the groups of cells being shifted in turn from the primary to the second circuit and vice versa by a continuously-operating switch. In the arrangement shown in Fig. 1, the groups 1, 2, 3 are connected in the primary circuit with the generator g for charging, and the groups 4, 5, 6 are connected in series to discharge in the secondary circuit. As the controlling-switch is operated the group 1 is disconnected from the primary and connected in parallel with the group 4 in the secondary circuit, as shown in Fig. 2. The group 4 is then disconnected from the secondary and connected in the primary circuit. The other groups are transferred in a similar manner, so that recharged cells are constantly transferred from primary to secondary, and discharged cells are transferred from secondary to primary. Any ratio may be obtained between the primary and secondary voltages by suitably choosing the number of groups and cells. The voltage in the secondary circuit may be regulated by varying the speed of the switching-operation or by changing the relative periods of charge and discharge.

[Class 38 (iv)] [Also in Group XL (c)] Radio navigation.-An aircraft guiding system comprises a number of radio beacons, situated at suitable points such as airports, each beacon consisting of two or preferably three pulsemodulated transmitters, the transmitters being arranged so that a pulse radiated by a first transmitter A is repeated by the other transmitters B and C after predetermined time intervals so that substantially radial course lines are set up, each characterised by a particular time interval between the reception of the pulse from the first, A, transmitter and the counterpart pulse from one of the other transmitters. At each beacon a stable frequency oscillator 20, Fig. 4, controls the pulse recurrence frequency, through pulse modulator 21, of transmitter 22 feeding antenna 23 of the first or A station. The output of circuit 21 is also fed through delay devices 24 and 27 to B and C transmitters 26 and 29 over land lines 25 and 28 respectively. To monitor the beacon, the output of pulse modulator 21 is also fed through a calibrated adjustable delay device 30 to a gate circuit 31 which allows input signals from antenna 33 and receiver 32 to pass over one and then the other of two paths for a predetermined short period, the change-over from one path to the other being effected by the incidence of the delayed pulse from unit 30. The two output paths are applied in opposite sense to centre zero meter 34, no indication should be produced when delay device 30 is adjusted to the same delay as that of the received pulses at A from B or C as the case may be. Automatic control of the B and C transmitter timing may be effected by using two monitoring circuits controlling delay devices 24 and 27 through servomotors.

Convention date, March 7, 1932. [Classes 40 (iii) and 40 (v).] The frequency of a synchronising-signal is a whole-number fraction of the line frequency and an integral multiple of the picture frequency. The synchronising-frequency is in a part of the frequency spectrum little used by the picture signals, and is equal to ##2À#b, where f2 is the line frequency and fb the picture frequency. The synchronising-signal has an amplitude greater than the maximum picture signal, and is separated from the picture signals at the receiver by a tuned filter, Fig. 1 (not shown). The synchronising-signal is reduced to the picture frequency, Fig. 3, and multiplied to the line frequency, Fig. 4, by circuits generating relaxation oscillations. The frequency reduction from 2500 cycles to 25 cycles is performed in a plurality of stages 29-32 reducing respectively by one fourth, one fifth, and one fifth.
