Title: Improvements in sighting apparatus for machine guns and the like
IPC: F41G3/00
Filed: 1937-08-12
Abstract: 502,179. Gun sights MACRAE, A. E., AINLEY, J. R., and GOODE, B.. W. K. Aug. 12, 1937, No. 22233. [Clsss 92 (ii)] Relates to dial sights of the kind bavlng graduated thimbles i for rotating a worm l<1> gearing with the graduated dial h which supports the tube or other sight a. According to the invention, the memberf<l> carrying the sight is mounted for rotation independently of the dial and can be engaged with or disengaged from the dial by operating a spring-controlled slide k. The arrangement is such that, in indirect sighting, the dial may be returned to zero reading after each setting of the gun in azimuth, the sight being restored to the datum line after pushing the slide k to the left against the action of a spring to disconnect the catch k1 which locks the member.f<1> to the dial. A milled worm l<2> permits of fine adjustment of the member f<1>. When a new datum line is chosen, the catch k<1> is restored to the locking fork k<3> on the slide k. Adjustment of the thimbles i is controlled by a spring lever t, Fig. 9, hinged at t<1> to click against teeth t<3> on one thimble, the lever engaging the other thimble under the action of a screw t<4> to clamp the parts.

Title: Polar Display of Television Chrominance Vectors.

IPC: H04N17/02
Filed: 1967-05-12
Abstract: 1,170,118. Vectorscope demodulating circuit. BRITISH BROADCASTING CORP. 2 May, 1968 [12 May, 1967], No. 22259/67. Heading H4F. A demodulating circuit for a vectorscope for use with a PAL television signal which allows the +V vector direction to be unambiguously identified on the display in relation to the colour burst vector comprises two synchronous demodulators 6 and 8, one 6 being fed with the input signal and a reference phase carrier signal produced by an automatic phase control loop consisting of a synchronous phase detector 2 controlling a variable reactance 3 across a crystal oscillator 4, and the other one 8 being fed with the input signal and a quadrature phase carrier signal produced from the colour burst of the input signal by a 90 degrees phase shift network 9 fed from oscillator 4. A switching circuit comprising modulator 10 and bistable circuit 11 is arranged to periodically invert the input signal applied to demodulator 8. This switching circuit is phased by comparing the phase of the output of the oscillator with the instantaneous phase of an applied colour burst. Further the switching waveform is so synchronized to the line pulses that switching transients occur when no colour carrier is present.

Abstract: 352,750. Lift-gate fastenings. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Schindler & Co. ; 2, Sentimattstrasse, Lucerne, Switzerland.) July 24, 1930, No. 22328. [Class 78 (iii).] The locking member b of a lift well gate mechanism is prevented from turning with the unlocking lever e by arranging that the direction of the force P exerted by a control lever a on the lever e passes through or below a fixed pivot D. When the control gear is operated, the lever a is rocked over by a shaft rod G, and a member b with which the lever a engages by a pin-and-cam connection n, c, is brought into the position shown in Fig. 2 to look the bolt R The lever e is rocked about its pivot d on member b by a spring f. On the control gear being disengaged the lever a returns to its original position Fig. 3, and throws over lever e with which it engages by a pin and cam connection i, k. The force P being directed through or below the pivot D, member b remains in its locking position until lever e connects with a ramp A on the cage. In a modification, Figs. 5 and 7, levers a, b have fixed fulcrums d<1>, d2, and a two-armed unlocking lever e is pivoted at d<3> on an arm a<1> of the lever a. One end of the lever e supports a roller h which bears against the cage ramp A during the unlocking action. The other end carries a pin n engaging with a guide slot K. The centre line M<1>, M<2> of the slot passes below the pivot d<1> to prevent member b turning with the lever e.

Testing transmitters and receivers. - Comprises a test panel for enabling any of a number of loud-speaking telephone receivers to be connected, with or without capacity in series and inductance in shunt, to a wireless set. Fig. 2 shows the underside of an ebonite base 2 which is mounted in a box and carries pairs of terminals 7, 7a for the telephone receivers, pairs 5, 5a and 6, 6a for connection to the output circuits of two alternative wireless sets, a condenser 4, an inductance 3, and switches which enable one or more receivers to be connected across either pair of wireless terminals, with or without the reactances 3, 4 in circuit. Thus the switch 32 enables the conductors 15, 15a to be connected respectively to the terminals 5 and 5a or 6 and 6<a>, or to be disconnected from either pair, the switch 24 enables the inductance 3 to be connected across the conductors 15, 15a, or to be disconnected, the condenser 4 (which is connected between the conductors 15<a> and 13) being short-circuited in the latter case; and each pair of telephone terminals 7, 7<a> is associated with a switch 10 so that the telephone can either be cut out or connected across the conductors 13, 15. In a modification there is only one pair of wireless terminals; these are connected directly to the conductors 15, 15<a>, the switch 32 being omitted.

Abstract: An immersion tin coating (at least 99% Sn, remainder Cu) is produced on aluminium or its alloys, in preparation for electroplating, by immersing cleaned aluminium, e.g. for between 5 and 40 seconds, in an aqueous solution, e.g. at between 32 and 65  DEG C., composed of 23-59 g./l. of Sn+4 ions (added as K2Sn(OH)6), 6-15 g./l. of CN ions (added as alkali metal cyanide), 1-3.5 g./l. of OH ions (added as alkali metal hydroxide) and 1.5-11.5 g./l. Cu+ ions (preferably added as CuCN, but possibly as stannate or potassium copper cyanide), sufficient alkali metal cyanide being added to complex the copper. At least 20% mole of alkali metal present in the solution is preferably potassium, the remainder being sodium; ideally all the alkali metal is potassium.  A tin-copper alloy, e.g. between 40 and 60% Sn with remainder Cu, is then electrodeposited on the initial immersion tin coating from a bath having the same composition as the above immersion bath, e.g. using current densities of 1-15 amp./sq.dm. for conventional batch plating but up to 150 amp./sq.dm. for continuous wire or sheet plating. Other metals may be deposited directly on to the thin tin immersion coating, e.g. Cu, Sn, bronze and Ni; or on to the tin-copper electrodeposit, e.g. bronze (from a cyanide bath), copper (from a pyrophosphate copper bath), nickel (from a Watts' nickel solution), chromium and also Sn-Ni, Cu-Ni-Cr alloys. Preferably the metals are electrodeposited from baths having a pH value between 4 and 9.  Multi-alternate layers of tin and tin-copper alloy may be deposited by interruption of the current. For Cu+ contents as low as 1.5 g./l, such materials as tartrates, citrates, gluconates and saccharates may be added to the above baths.
