Title: Multifocal glass lens mfr. - using photochromic glass fused to another glass and heat treated
IPC: C03C4/06
Filed: 1976-03-31
Abstract: A photochromic multifocal glass lens consisting of a photochromic glass as the major constituent and at least one segment of glass fused to the photochromic glass and composed of glass with a refractive index greater than the refractive index of the photochromic glass, is made by heating at 510-550 degrees C for 10-50 mins. a glass which is potentially photochromic and which contains (by wt.) 48-57%SiO2, 6-10%Al2O3, 15-22%B2O3, 0.8-2%Na2O, 2.4-3.1%Li2O, 0-4%K2O, 3.2-7.2%Na2O+Li2O+K2O, 4.5-5.3%PbO, 3-9%BaO, 0-7.2%ZrO2, 0.1-0.6%Ag, 0.01-0.1% CuO, 0.15-1.2% Cl, 0-1% Br, 0-0.1% I and 0-1.2%F. The heat treatment initiate grain growth of Ag halide crystals in the glass. The potentially photochromic glass is then fused to another glass of greater refractive index by heating treating at 635-670 degrees C for 15-45 mins. this treatment also develops the photochromic properties of the principal glass. The lens is then cooled. The photochromic properties are uniform and reproducible. The photochromic glass is not overdeveloped as the photochromic propertie are not developed until the second heat treatment.

Title: Cathode ray deflection voltage stabilization - compensates for mains and beam loading fluctuations by sync. pulse width differentiation controlling power pack
IPC: H04N3/18
Filed: 1976-08-31
Abstract: The supply voltage to the defection system of a CRT can be stabilized not only against mains supply fluctuations but also against high tension fluctuations due to the beam loading. The number of the connections between insulated and not insulated chassis parts has been kept to a minimum. The sync pulses are differentiated by the network (35, 36) and passed to transistors (43, 44). A circuit (27, 28, 29, 31, 32), coupled to the transistors and the deflection system produces a first control signal which is characteristic for the level of the periodical voltage pulses (26). This controls the transistor bias and the width of the differentiated sync pulses (75). A circuit (50, 51, 53) at the transistor output is coupled to the power pack (10) and derives from the width-modulated sync pulses (75) a second control signal.

Title: Rubberised fabric for skirt of gas cushion vehicle - has thermoplastic threads pretreated by heat and tension
IPC: D06N3/00
Filed: 1976-10-27
Abstract: Coated fabric is made by applying adhesive to a weave of thermoplastic threads or yarn and then applying an elastomeric layer to each face of the weave. The weave, or the thread or yarn from which it has been woven, has been pretreated by softening with heat and tensioning so as to reduce the inter-filamentary spaces in the thread or yarn. The prod. is used esp. for skirts of gas cushion vehicles, i.e. hovercraft. Penetration of water by capillary action is prevented. This reduces the tendency to delamination under the severe flexing to which the fabric is subjected.

Title: Electrified fence control circuit - has pair of auxiliary windings on transformer secondary side to charge pair of condensers
Inventor: SINDT HUGO
IPC: G01R31/50
Filed: 1977-04-12
Abstract: The electric fence has a charging condenser which is periodically discharged through the primary of a transformer to generate high voltages for feeding to the fence in the form of damped pulses whose voltage level can be controlled to an optimum value. To improve the monitoring of the output pulses especially when operating from a battery supply the two first immediately following half waves of the pulse are compared with a reference value. The transformer may be given a pair of auxiliary windings (W1, W2) on the secondary side charging a pair of condensers (C1, C2) through rectifiers (D1, D2). The voltages across these condensers are compared in a comparator (D) and their ratio is compared with a reference value to assure that the damping has not fallen below a preset level.
