Title: Improvements in and relating to lamp tube fittings
Inventor: DUBERY ROY FREDERICK
IPC: F21V25/12
Filed: 1962-12-18
Abstract: 1,080,281. Lamp caps and holders. BECK & CO. (METERS) Ltd. Feb. 3, 1964 [Dec. 18, 1962], No. 47772/62. Heading H2E. [Also in Division F4] A flameproof lamp fitting comprises a transparent or translucent guard tube 2 closed at one end 4 and mounted at the other end in a contact block, and a tubular lamp 22 extending within the guard tube between contacts on the contact block and contacts on a contact plate 24 disposed in the closed end of the guard tube, biasing means being arranged to act on the contact block or on the lamp to urge them bodily towards the closed end of the guard tube so that, in the event of the lamp or guard tube being smashed, the resulting movement breaks the electric circuit to the lamp. The contact block comprises a fixed part 28 secured to a housing portion 12 and a movable part 34 having a tapering inner surface 36 adapted to be a very loose fit in a correspondingly tapered recess in the part 28. Sockets 38 are provided in the part 34 to receive pins 40 on the end of the lamp, and plungers 43 in the part 28 are urged by springs 44 towards the sockets 38 and act as the electrical connections between the sockets and spring contacts 45 joined by terminals 30 to input leads (not shown). The contact plate 24 may be urged towards the lamp by a spring 50 of sufficient strength to overcome the force of the springs 44, and the leads 42 from the contact plate are also connected to spring-loaded plungers 43 (not shown) in the contact block. If the lamp or guard tube is smashed the springs 44 urge the plungers and the part 34 towards the right and electrical connection between the plungers and the contacts 45 is broken. The housing portion 12 is screwed into a fixed housing portion 16 and may swivel relative thereto within limits imposed by a stop 20.

Title: Tandem sampling controller
IPC: H03L7/16
Filed: 1970-10-07
Abstract: 1329446 Active filters; frequency control systems HEWLETT-PACKARD CO 7 Oct 1970 [11 March 1970] 47785/70 Headings H3A and H3U A sample and hold circuit arrangement comprises tandem connected samplers 9, 17 with respective storage devices 15, 19, a circuit 31 for supplying the signal to be sampled, a sample trigger generator 31 whose output has a repetition rate equal to or harmonically related to the repetition rate of the sampled input signal, the sampling signal being applied directly and via a delay network 21 to the respective inputs of samplers 9, 17 and a utilization circuit responsive to the output of the second sampler 17. In operation, the first sampler 9 samples the input signal for the duration of the sample trigger signal and stores it at 15 while the second sampler 17 after a delay determined by 21 samples the steady or base line value of the stored signal. The output of sampler 17 is applied to retroactively control a local oscillator 33 so that it has a frequency equal to the sum of a variable frequency applied to a mixer 31 and a reference frequency applied to the control input of sampling trigger generator 13. Signal variations at the output of sampler 17 arising through capacitive feedback are compensated by the series combination of an amplifier 26 and an ajustable capacitor 28.

[Also in Division G2] The photo-conductive layer of an electrophotographic material consists of or contains the stable leuco base of a triphenylmethane dyestuff in which one of the phenyl groups is substituted by a nitro group, a trifluoromethyl group, or an alkyl sulphonyl group and in which the remaining phenyl groups are identically or differently substituted in the p-position by hydroxyl groups, alkoxyl groups, amino groups, or substituted amino groups. One or more of these compounds may be used alone or with usual binders, plasticizers, and sensitizers to form a layer; they may be used with other photo-conductors, for example with zinc oxide and a halogen-containing polymeric binder; and they may be used as sensitizers for photoconductive polymers. In one of the suggested methods of development, the developer powder contains an oxidizing agent such as chloranil so that the photo-conductive leuco base is converted to the dyestuff to form a permanent image.

Title: Improved power supply for implantable electromedical apparatus
IPC: A61N1/378
Filed: 1969-10-22
Abstract: 1287750 Standby supply systems; inverting MEDTRONIC Inc 22 Oct 1969 [28 Oct 1968] 51833/69 Headings H2F and H2H A power supply in an implantable electromedical device comprises two parallel sources connected by an asymmetric conducting element so that, when the output voltage of one source falls appreciably below that of the other, only the second source continues to supply the device. The output may be connected through a voltage doubling circuit. In the arrangement shown, the power supply 10 comprises two equivalent batteries 21, 22 with their positive terminals connected to a common output line 26 through respective diodes 23, 24. Initially, both batteries will supply the device 11, which may be a cardiac pacemaker, but if one battery should fail or drop in voltage relative to the other, the corresponding series diode 23 or 24 will be back-biassed and the total power will be provided by the other battery. In a modification, Fig. 3 (not shown), a further diode is connected in series with diode 23 so that initially the battery 22 forms the main current supply.  In the system shown, the device 11 emits signals on lines 52, 53 to control an output voltage doubling circuit 12 which receives power directly on line 26 (B + ) and is connected by terminals 31, 32 to the body in which the system is placed. A first signal ensures that all the transistors 51, 46, 43, 38 in the circuit 12 are off, and a capacitor 35 then charges through resistors 37 and 42 and through the body by way of terminals 31, 32. Next, a signal is supplied to turn on all the transistors, and the capacitor 35 now charges in the reverse direction through transistors 43 and 38 and again through the body. The charging cycle is normally repeated as determined by the device 11.
