Title: Improvements in and relating to the manufacture of composite glass
IPC: B32B17/08
Filed: 1927-02-24
Abstract: 288,782. Mallabar, H. J., and Non-inflammable Film Co., Ltd. Feb. 24, 1927. Compound transparent sheets. - Composite sheets of glass and cellulose acetate are formed by first coating the surfaces to be united with a layer of gelatine which when dry is softened, and the sheets are then united by pressure. To secure adhesion of an adequate coating of gelatine to the glass, it is treated with a 2 per cent waterglass solution or a 2 per cent gelatine solution to which is added a small quantity of chrome alum neutralized sodium carbonate. The cellulose acetate is treated with ether before coating with gelatine. A solution for softening the coated sheets is preferably made by soaking 80 parts of hard emulsion gelatine in 50 parts of glacial acetic acid and 80 parts of distilled water for one hour at room temperature, then raising the temperature to 50‹-60‹ C. and adding 4000 parts of methyl alcohol, at the same temperature, slowly and with constant stirring; to this mixture when cool 6000 parts of acetone are added. After dipping in this solution the sheets are united in a hot hydraulic press. One or more tints may be given to the gelatine or any of the sheets. A blue-violet dyestuff such as methyl violet B or methyl violet 2B may be used to neutralize the yellowish tint of cellulose acetate and to produce a water white compound sheet, and one sheet of glass may be given a blue colour and a second a pink colour.

Abstract: 632,205. Odometers. SQUARE D CO. Feb. 25, 1947, No. 5495. Convention date, March 26, 1946. [Class 106 (iii)] [Also in Groups XXXVII and XL (b)] In an air mile recording system movement of the indicating member of an air speed indicator controls the speed of a motor by means of a photo-cell, the total revolutions of this motor being totalled on a revolution counter to indicate distance travelled. As shown, a conventional air speed indicator 11 having a pressure connection 12 and a static connection 13 has its pointer replaced by a mirror 3 upon which parallel light from a source 1 falls. This light is reflected on to a mirror 4 mounted in place of the pointer of a drag cup tachometer, the rotating magnet of which is driven by a motor 19 also coupled to a revolution counter 25. The light is brought to focus on a photo-cell 6 partly covered by a mask 7. When the beam is on the mask, a tube 29, Fig. 2, associated with the photo-cell is inert and a two-phase motor 35 rotates in one direction due to different capacities 38 and 39 in its two fields and drives a rheostat 43 in a direction to (say) increase the speed of motor 19. When, as a result of the change of speed, the beam moves on to the photo-cell, the tube 29 fires, shunting condenser 38 and reversing the direction of rotation of motor 35 to bring down the speed of motor 19. In this manner motor 35 continually hunts to and fro, the revolutions of motor 19 being totalled on the counter 25 which indicate airdistance travelled.

Patent GB-669481-A (GB)
Title: Improvements in and relating to apparatus for comparing unidirectional voltages
IPC: H04Q1/18
Filed: 1949-03-03
Abstract: 669,481. Automatic monitoring apparatus. BRITISH BROADCASTING CORPORATION, PEACHEY, F. A., and RUSSELL, C. GUNN-. March 3, 1950 [March 3, 1949], No. 5890/49. Class 40 (iv). In a circuit arrangement for comparing two unidirectional voltages the two voltage sources are connected in series opposition and the difference voltage is applied via a differentiating circuit to a device which responds when the voltage applied to it exceeds a predetermined value. In this way difference voltages changing relatively rapidly are effective to operate the device, whereas those of a permanent or relatively slowly changing nature are ineffective. The differentiating circuit may comprise a condenser in series with a resistor, the output voltage being taken from across the resistor. The circuit arrangement of the invention may be used in an automatic monitoring apparatus of the type disclosed in Specification 655,688 in order that changes in transmission equivalent of a slow nature will not operate the alarm or indicating device. The two voltages V1, V2 to be compared are applied to terminals 10, 11 and 12, 13 respectively, a condenser 16 being connected between terminals 11 and 12. The voltage across 10 and 13 is applied between the control grids of two triodes 17, 18 in the anode circuits of which is connected a differential relay 19. If V1 and V2 are equal the anode currents of valves 17, 18 are equal and relay 19 remains unoperated. If VI or V2 changes by 6 volts (equivalent to an unbalance of 3 db. on a system being monitored) relay 19 operates due to the difference in anode currents. If, however, this change is of a slow nature the condenser 16 becomes charged to the difference voltage and the voltage between 10 and 13 remains zero. Condenser 16 and resistors 14, 15, 20 and 21 constitute a differentiating circuit which therefore passes sudden transient voltage changes but not slow changes in voltage. If the steady difference between V1 and V2 exceeds 6 volts then whenover VI and V2 fall to zero the charged condenser 16 operates relay 19. The cathode leads of valves 17, 18 include variable resistors 22, 24 and filament lamps 23, 25, respectively, and a common cathode resistor 26 is provided. The resistances of lamps 23, 25 increase with increase of anode current in the respective valves and the arrangement compensates for changes in mutual conductance of the valves with change in supply voltage and maintains the total anode current of the valves substantially constant. Modification. Terminals 11, 12 may be directly connected and terminals 10, 13 be connected to a full-wave rectifier the output of which is passed through a differentiating circuit to an indicator.

Title: Improvements in and relating to the polymerisation of coumarone and indene
IPC: C08F240/00
Filed: 1946-02-26
Abstract: Coumarone and indene are polymerized by causing the material containing them, e.g. naptha, to flow through a tower in which it is contacted with gaseous hydrofluoric acid.  Preferably the hydrofluoric acid is static, i.e. countercurrent flow is avoided. An iron or steel column filled with coke lumps is evacuated and filled with anhydrous hydrogen fluoride under a pressure of 1 inch water gauge.  A U-tube attached to the bottom of the column acts as a gas seal.  Naphtha is run down the column and through the U-tube and the atmosphere of hydrogen fluoride is maintained from a vessel thermostatically controlled at 18 DEG -19 DEG  C.  Hydrogen fluoride is removed from the naphtha by heating at 100 DEG  C., cooling and washing with sodium carbonate solution and water. Unpolymerized naphtha is removed by steam distillation and the resin run out from the bottom of the still.
