Title: Control of Electrostatic Deformation of a Thermoplastic Film
IPC: G03G16/00
Filed: 1966-11-07
Abstract: 1,162,834. Deformation imaging. RANK XEROX Ltd. Nov.7, 1966 [Nov. 8, 1965], No.49760/66. Heading G2H. The controlled development of deformation images comprises heating the surface of a thermoplastic film so that it deforms under the action of an imagewise distributed electrostatic charge thereon, detecting the amount of deformation, and controlling the heating in response to the amount of surface deformation detected. The degree of surface deformation may be determined optically by measuring the amount of visible light or irradiation from a light source which is reflected from or transmitted by the film during development; this may be measured by a photoelectric cell connected to a control means which at a predetermined light value closes a shutter in front of a heat source used for the deformation, thus terminating the deformation. The light and heat sources may be in a single unit. The thermoplastic film may be carried on an opaque or transparent photo-conductive layer (e.g. selenium) carried on an opaque or transparent conductive base (e.g. tin oxide-coated glass), dependent on whether light measurement is by reflection or transmission respectively. The material may be charged and exposed several times before development.

Abstract: 1397061 Dolls &c M I GLASS [trading as MARVIN GLASS & ASSOCIATES] 31 Oct 1973 [6 Nov 1972] 50663/73 Heading A6S A doll &c, changes the expression on its face as it is moved from a seated position, Figs 2, 3, to a standing position, Fig 5, and vice versa. The doll has a one-piece flexible outer covering 36 filled with beans, &c. A string 62 is secured at its lower end 64 to the bottom of the covering 36 and at its upper end 68 to an operating rod 66. When the doll is raised to the standing position, the string 62 is tightened to pull downwards the operating rod 66 and thus turn a lever 70, journalled upon a support 72 in the dolls head 18, from the Figs 2, 3 to the Fig 5 position. A yoke 84 pivoted to the end of the lever 70 is thus raised. Simultaneously a support plate 88 connected by a pivot 90 to the yoke 84, is tilted upon its mounting pin 46, Fig 7. Simulated eyes 44 on the front of the support plate 88 are thus turned from a raised, sad expression with their irises 44a, Fig 6, partly hidden, to a lowered position with their irises pointed forwards. Two cheek simulating discs 50, Figs 6, 8, 9, in front of the doll's head 18, are journalled by pins 52 extending into the head and having forks 58 embracing pins 80 at the sides of the yoke 84. Accordingly when the yoke 84 is raised, as described, the two cheek discs 50 are rotated. A resilient strip 60, Fig 6, is secured at its ends to the cheek discs 50, so that as they turn, the strip is raised from its lower position, simulating a sad expression, to its raised position (shown in full lines) simulating a happy expression.

The vacuum may be applied through one or more pipes 10 which may communicate with the mould cavity via a groove 7 in a peripheral flange 5 of the female mould part 2. The mould parts 1, 2 may be sealed against the atmosphere by a resilient ring 8, e.g. rubber, which may be attached to one of the skirts 4, 6 surrounding the mould parts 1, 2. The moulding material may be poured into the cavity through a tubular boss 11 which may be closed by a shouldered stopper 12. After moulding, the mould parts 1, 2 may be parted by pressure air or gas introduced through the pipes 10 via three-way valves 13. Reinforcement, e.g. glass fibre, and preformed inserts may be placed in the mould cavity prior to the introduction of the moulding material, the mouldings thus produced may comprise an insert sandwiched between two skins of moulding material. The latter may be a thermosetting resin. A gel coat may be initially applied to the female mould part 2. The male mould part 1 may be translucent and the mould parts may be formed of glass-fibre reinforced resin.

Abstract: 1449204 Gas-permeable cathode CANADA MINISTER OF NATIONAL DEFENCE 1 Nov 1973 [1 Nov 1972] 50833/73 Heading H1B A cathode for a fuel cell or metal-air battery comprises a current-collecting grid 11, e.g. of nickel, enclosed in a substrate 12 of activated carbon or sintered nickel having one face covered with a semi-permeable hydrophobic membrane 14, e.g. of fibrous P.T.F.E. or microporous polypropylene. The porous structure of the substrate 12 contains manganese dioxide catalyst produced in situ, i.e. either in the substrate or on the material which is eventually included to form the substrate, and bound within the pores by a fluorocarbon polymer, e.g. P.T.F.E. In the instance where the substrate 12 is of activated carbon the electrode may be made by mixing activated carbon with potassium permanganate and reducing the permanganate to MnO 2  by heating or by adding hydrogen peroxide. An aqueous suspension of a fluorocarbon polymer is added to the mixture of MnO 2  and activated carbon to form a paste which is applied to both sides of the grid 11 and the substrate is formed by hot pressing. The membrane 14 is then applied. In a modification of the method the aqueous suspension of the fluorocarbon polymer is added before the reduction of the potassium permanganate. In the instance where the substrate 12 is of sintered nickel, the substrate is impregnated with aqueous manganous nitrate solution which is reduced by pyrolysis to MnO 2 . An aqueous suspension of a fluorocarbon polymer is applied to both sides of the substrate and dried by heating and, finally, the membrane 14 is applied. In a modified method the aqueous suspension of fluorocarbon polymer is mixed with the aqueous manganous nitrate solution.

Title: Method and circuit for monitoring and detecting sweep signal failure
IPC: H04N5/228
Filed: 1973-11-05
Abstract: 1388999 Cathode-ray tubes operating circuits WESTINGHOUSE ELECTRIC CORP 5 Nov 1973 [20 Nov 1972] 51208/73 Heading H4T In an arrangement responsive to an abnormal sweep voltage (e.g. total loss, or a shift in the zero crossing point), a digital signal is produced which has one level for a normal condition and another level for an abnormal condition, the signal being sampled at a rate equal to or greater than the repetition frequency of the sweep voltage so that in the event of the occurrence of an abnormal condition a signal for preventing damage to the tube (e.g. by blanking the beam), is produced early in the cycle of the abnormal sweep.  Fig. 1, shows the general arrangement which employs an abnormal sweep detector 18 to safeguard a vidicon or image orthocon pick-up tube 18 in the event of an abnormal vertical sweep voltage and Fig. 2, shows details of the detector 18 the various waveforms occurring in which are shown in Fig. 3. Referring to Figs. 2 and 3, a monostable multivibrator 26 the time constant of which is approximately equal to one half the period of the vertical sweep voltage VS (waveform A) is triggered by the vertical blanking pulses VB (waveform C) and alternately conditions AND gates 20, 24 which have as respective second inputs the non-inverted sweep voltage VS and its inverse derived via inverter 22. The alternately produced outputs from gates 20, 24 are then fed via OR gate 28 to the reset steering input R and via an inverter 30 to the set steering input S of a bi-stable multivibrator F.F 30. In operation, assuming a normal sweep voltage VS is present, the output from OR gate 28 which is at high level = "1" during the complete period of the sweep causes FF30 to be reset by a pulse of the mixed blanking (vertical and horizontal) train MB (waveform B), so that the Q output from which the protection pulse is derived is low = "0". If the sweep voltage VS is absent, or if the zero crossing position 36 (Fig. 3) has shifted, e.g. to position 40, the output of OR gate 28 goes low = "0" either at the start of VS (when the latter is absent) or on the occurrence of the next pulse of the series MB (when the zero crossing has shifted, so that FF30 is set and a high level = "1" is produced at output 34. This output is then employed to blank the tube beam and in the case of a pick-up tube in which the cathode voltage is automatically increased as the illumination of the scene decreases, to inhibit the cathode voltage. A second embodiment detects two "crossover" positions spaced by a small amount "above" and "below" the true zero crossing and if each detected "cross-over" signal does not occur during each halfcycle of the sweep voltage waveform an abnormal condition signal is produced (Figs. 4 and 5, not shown).
