Abstract: 1448124 Lamp holder FAUSTO CARELLO & C SpA 30 Nov 1973 [13 Dec 1972] 55571/73 Heading H2E Bayonet holder 4, for a lamp 1 having two base contacts 3 on cap 2, consists of integrally mounted plastics body comprising sleeve 7, mounting flange 8 and base 11, with connecting wall 12 joining base 11 to plate 8 of cylindrical form with opposite quadrantal arcs removed to allow two bent sheet metal contact strips 5 to slide in through gaps. Guides 14 and 15 restrain contacts on which detents 26 engage recesses (25, Fig. 3, not shown) in the base for retention. If the lamp has only one central base contact, one strip 5 only is inserted, with modification of strip or base to give central location. Side contact 6 has "U" part 31 to slip over thinned part 31a of sleeve wall 7, while tang 32 enters slot 33 where it is retained by its detent, 32a and tab 34 seats at 35 on flange 8, secured and earthed if required by a screw through lower mounting hole 9. Sleeve 7 has internally moulded bayonet slots 37, the pins 43 being retained after insertion of lamp by forward pressure from strips 22 of contacts 5. Connections are made to tags 23 and 32 of contacts 5 and 6 respectively. Moulding of integral body 4 is facilitated by the absence of undercuts; bayonet slots 37 open at the rear into the blank quadrants of wall 12, and lateral projections 17 and 18 of guides 14 and 15 have matching apertures 24 behind for plungers to enter during moulding.

Filed: 1966-12-13
Abstract: 1,154,046. Sealed accumulator. W. GREUTERT. 13 Dec., 1966 [13 Dec.. 1965], No. 55696/66. Heading H1B. A sealed accumulator, which later can be overcharged without developing a dangerous internal gas pressure, is overcharged with the casing open, when otherwise finished, at least until the charging voltage has fallen to a constant value after passing through a maximum, before being sealed. The process is suitable for nickelcadmium, silver-cadmium and lead accumulators. Preferably the charging current is held constant during the overcharging. A second overcharging before sealing, after a complete or partial discharge, is beneficial.

Patent GB-701932-A (GB)
Abstract: 701,932. Calculating-apparatus. MINISTER OF NATIONAL DEFENCE OF CANADA. April 30, 1951 [June 16, 1950], No. 10108/51. Class 106 (1) [Also in Group XV] An air navigational computer is constructed to show solar lighting conditions over air routes in polar regions, so that flights can be timed to avoid twilight when astronavigation becomes impossible. The computer shows the track of a projected flight in relation to the sunset-sunrise line as seen by an observer in space on the earth's axis, the sunset-sunrise line is seen stationary, and the flight track includes the earth's movement eastward as well as the movement of the aircraft relative to the earth. The computer comprises a frame 24 (Fig. 1) fitted with a rotatable transparent plotting window 42 below which is a slide 38 (see also Fig. 5) marked with a polar map A, the sunset-sunrise line B, a twilight line D, and a scale E for the sun's declination. In using the apparatus, the track V of the flight is first marked on the map A together with points reached after convenient intervals, e.g. one hour. The slide is then inserted in the frame with the map in register with the window 42 which is set with the zero of an hour's scale N opposite a stationary index Q. The takeoff point is now traced on to the window 42, and the interval points of the route are also traced after successive rotations of the window corresponding to the interval. The traced points are then joined by a smooth curve W (Fig. 8) and represents the track as seen by the imaginary observer. The slide 38 is next adjusted to position the sunset-sunrise line B according to the date of the flight by bringing the appropriate marking on the declination scale E into register with an index R. Finally, the flight track W is orientated in relation to the sunset-sunrise line B according to the time of day by turning the window 42 so that the hour angle of the time of take-off on a scale M registers with the index Q. It can then be seen whether and what parts of the flight are affected by the twilight belt between the lines B and D. Areas above and below this belt correspond respectively to daylight and darkness A line C is marked in the daylight area at which the sun's altitude is 5 degrees and below which bearings are affected by refraction. The declination scale E is repeated for flying heights of 10,000 and 20,000 feet at lines F and G so that the effect of flying height can be taken account of, and the scales mav be marked with dates instead of the sun's declination. A high latitude planisphere (see Group XV) is provided on the reverse side of the apparatus. The apparatus is constructed from plastic sheet, the frame 24 in five laminations bolted and/or glued together and apertured for accommodation of the discs 42 and slide 38.
Patent GB-713046-A (GB)
Abstract: 713,046. Photo-electric apparatus for measuring voltages. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. April 25, 1952 [April 25, 1951], No. 10473/52. Class 40 (3). [Also in Group XXXVI] A device for amplifying and measuring a D.C. comprises a first circuit in which the input terminals are connected in series with a moving coil galvanometer without restoring torque and a resistance, and a second circuit having one side earthed in which the intensity of an A.C. source is varied responsively to a D.C. adjustable in dependence on the galvanometer deflection, and supplies a rectifier whose output is connected in series with the resistance of the first circuit and a measuring instrument; an inductive coupling being inserted in the second circuit to isolate the part comprising the A.C. source and having one side earthed from the part comprising the rectifier, measuring instruments, and resistance. Fig. 1 shows a measuring circuit in which an input voltage across terminals 1, 2 causes a current to flow in the resistance 8 through the moving coil 3 of an unrestrained galvanometer, whose deflection operates a variable element (e.g. capacitance or mutual inductance) of a control circuit 5 which may be of the kind described in Specification 587,459, [Group XXXVI], whose correspondingly variable output modulates the anode current of an A.C. energized thermionic tube 6, which energizes the control winding of a magnetic amplifier-transductor 10, 11, 12. The second winding of the latter is connected in series with an A.C. source 13, 14 and a bridge rectifier 15, whose D.C. output current produces a balancing voltage across resistance 8 which at equilibrium is equal and opposite to the input voltage. The current supplied by the rectifier deflects a measuring instrument 7 to indicate the magnitude of the input voltage and the transductor serves to isolate the rebalancing side of the circuit from the input and rebalance controlling side. In a modification (Fig. 2 not shown) the transductor is replaced by an isolating transformer in the tube anode circuit whose output energizes the bridge rectifier. In Fig. 3 the excitation of the transductor shown in Fig. 1 is derived from the output of a photocell 30 polarized by voltage source 34 which is variably illuminated from a lamp 31 by a mirror 33 deflected by the galvanometer 3.
