Abstract: 1356914 Structural points L M L JANSSEN 16 Sept 1971 [12 May 1971] 43290/71 Heading F2M [Also in Division E1] Extruded hollow section horizontal and vertical frame members 1, 2 have longitudinally open compartments 4, 5 on either side of the central box 3. A locking device 16 which secures the two members together comprises a frame portion 17 the width of which engages between longitudinal flanges 12, 14 and 13, 11 in the box section 2 and a head portion 18 which engages in the open compartment 4 of an adjacent member 1. A V-section metal spring 25 fits in the rectangular aperture 26 of the frame portion 17 one, longer, arm of the spring resting against the outermost side of the aperture 26. The opposite side of the aperture abuts the flat part 28 of a metal dowel engaged in aligned holes 29 in the member 2. When the head portion 18 is inserted in the compartment 4 and rotated with the member 2 to engage under the flanges 6, 7, the dowel 27 is rotated with a special spanner to bring the steps 22, 23 on the head into engagement with the mouth of the compartment 4. Glazing or opaque panels 30 are fixed to either side of the framework by heat and sound attenuating spacers 32 and cover strips 31 which are snapped in place.

Abstract: 1520478 Detecting earth leakage THOMSON-BRANDT and LCC CICE COMPAGNIE EUROPEENE DES COMPOSANTS ELECTRONIQUES 22 Oct 1975 [24 Oct 1974 21 Nov 1974] 43452/75 Heading H2K In an electrical apparatus which is fed from an A.C. supply via a conventional differential current transformer responding to earth leakage and which comprises some components, carrying rectified current, which are double insulated from earth and other components, connected to the A.C. supply, which can only be single insulated, the two kinds of components are interconnected by connecting components whose characteristic values are such that should an insulation fault occur in one of the components carrying rectified current, the differential transformer will remain unsaturated and effective to respond to the fault. In Fig. 1 the D.C. motor 23 of a washing machine is supplied from an A.C. source through a differential transformer (not shown), a double pole switch 11 and a rectifier bridge 12 and is regulated by a conventional control circuit 17, 18, 22 ... A programmer 33 includes the switch 11 and switches 34 ... 38 all of which have class I insulation, with the motor and its control circuit components being provided with class II insulation. The latter components are connected to the switches 34 ... 38 through resistors 41 ... 45, whose values are chosen to give a total greater than 10,000 ohms which ensures that an insulation fault in the motor, its control circuit or bridge 12 has no adverse effect on the operational sensitivity of the differential transformer. The resistors may be replaced by capacitors (141 ... 181) having a total capacitance between 10,000 and 100,000 picofarads, Fig. 3 (not shown), which modification includes further resistors, capacitors and balancing diodes (142 ... 182, 145 ... 185, 143 ... 183 and 144 ... 184). The transformer sensitivity is also protected against the harmonics produced by regulation of the motor, since transmission of these harmonics to the A.C. supply is prevented.

A pulsometer pick-up comprises a housing M (Fig. 3), in which are mounted two spaced flexible diaphragms c, k, with a vibration transmitting fluid l therebetween, and a variable capacitor arrangement having at least one movable plate d 2 , d 2  (Fig. 5) for varying the capacitance. A rod t or other means connects one of the diaphragms c to at least one movable plate d 1 , d 2 . The plates d 1 , d 2  are preferably rings formed by metallization on the rod t. They co-operate with rings e 1 , e 2 , f (Fig. 4) acting as fixed capacitor plates formed on the interior of a casing n. The capacitor plates d 1 , d 2 , e 1 , e 2 , f are connected as a bridge network. In use the diaphragm k is placed in contact with the vibration source (e.g. the body adjacent the heart) and vibrations are transmitted to the upper diaphragm c and thus to the bridge network. The relative size of the diaphragms c and k provides amplification. The liquid I may be silicone oil, an aqueous salt solution or ethylene glycol. Local circuit.-Equilibrium of the bridge b (Fig. 1), is modified to the rhythm of pulsations at frequency f 1 . This frequency f 1  is superimposed on a carrier f 0  produced by an oscillator a. The resultant signal is amplified (g), demodulated (h) and the demodulated signal is amplified (i) for use in a visual observation or recording device or is transformed into an acoustic, oscillographic or oscilloscopic signal. Alternative capacitor arrangement.-Two movable capacitor plates q 1 , q 2  (Fig. 6) are mounted on a common operating rod t secured to a diaphragm c. The fixed capacitor plates are in the form of discs p 1 , p 2  and p 3 , apertured for passage of the rod t 1 .

Abstract: 1,118,217. Cutting webs. RANK XEROX Ltd. 22 Oct., 1965 [30 Oct., 1964], No. 44911/65. Heading B4B. [Also in Divisions G2 and G3] A paper web 28 which receives a developed electrostatic image from a xerographic drum 18 at a station 50 is cut into lengths by a cutter 104 which correspond to the lengths of documents (not shown) being copied. Documents to be copied are fed by endless belts 26 past a detector 44 having a photo-cell 60 which receives light from a lamp 42 by reflection from a mirror 62. The passage of the leading edge of a document causes the cell 60 to emit a low level signal output while the trailing edge produces a higher level signal. These signals are utilized in the control circuit, Fig. 3 (not shown) to control a magnetic recording device (70) having an endless magnetic tape (80), Fig. 2 (not shown) which is fed past read, write and erase heads (74) (78) and (76) at a speed preferably equal to the speed of the web 28 (Fig. 1). The cutter 104 is actuated by solenoids 108 in response to detection by read head (74), Fig. 2 (not shown) of magnetic markings on the tape (80) spaced apart according to the length of the document being copied as sensed by the cell 60, Fig. 1.

An inverting circuit for converting D.C. on lines 20 and 21 to an A.C. output on line 24 and comprising two SCR's 22 and 23 and a commutating choke 29 together with commutating capacitors 31 and 32, is characterized by the provision of a magnetic bias circuit comprising transformers 52 and 55 energized from a D.C supply on lines 75 and 76 so that they are initially saturated in one direction before the associated SCR is fired and saturates them in the opposite direction, thereby delaying the rise in current through the SCR and preventing damage to it, and is also characterized by the connection of a D.C. supply to lines 17A and 17B so that the commutating capacitors will always be charged to a sufficient level even if the D.C. supply on lines 20 and 21 should drop below this level. When SCR 22 is switched on the capacitor 31 discharges through it and winding 27 which induces a voltage across the total commutating choke to turn off SCR 23; the energy stored in the choke then discharges through the primary winding 63 and diode 66, and in addition is transferred inductively to secondary winding 64 and diode 33 or 34. The SCR 22 is shunted by a transient damping circuit 58, 70 and a similar circuit is provided for SCR 23. The circuit shown in Fig. 2 is one phase of a three phase inverter which may be used to supply a motor (Fig. 1, not shown), the frequency being controlled by an oscillator. The input power supply and the auxiliary supply on lines 17 may be derived from rectifiers supplied from a three phase A.C. supply.
