Title: Improvements in and relating to the Manufacture of Linoleum and the like.
IPC: D06N1/00
Filed: 1917-12-20
Abstract: 121,777. Craven, A. B., and Yorkshire Dyeware & Chemical Co. Dec. 20, 1917. Fatty acids; fatty oils.-A linoleum cement is obtained by distilling either the fatty acids from drying and semi-drying oils, or the oils themselves (except tung oil), or mixtures of these bodies, or by-products obtained in refining these oils, until the requisite resilient, tacky. and adhesive residue is obtained. The distillation may be effected with or without the use of superheated steam, carbon dioxide, or other inert gas, or vacuum. The distillate consists of non-polymerizable fatty acids with or without glycerine. The by-products employed are those obtained in refining oils by means of acid, alkali, or bichromate and acid, or by sedimentation, or the oily bodies recovered from fuller's earth. The products are improved by bleaching the raw materials before distillation as by treatment with bleaching-powder and acid, or with strong alkali. The raw materials may also be filtered in a filter-press to remove solid fatty matters and impurities. An increased yield is obtained by preliminarily polymerizing the raw materials by means of heat. Gum resins, resin, &c., may be added during or after the distillation. In the preferred procedure, the raw materials after a preliminary purification are heated to 270-300 C. for 1-2 hours to polymerize them, and are then distilled by means of superheated steam at temperatures gradually rising from 200 to 300 C., the operation taking 10-24 hours. The preliminary treatment of foots may comprise washing with strong alkali and acid. Crude cotton seed oil is washed with strong caustic soda. Linseed oil fatty acids are filter-pressed. The treatment of linseed oil and soya oil is described.

Title: Improvements in or relating to apparatus for indicating undercharge of a storage battery
Inventor: FIANDT RONALD MAYNARD
IPC: G01R31/00
Filed: 1962-05-18
Abstract: 971, 128. Testing batteries GLOBEUNION Inc. May 18, 1962, No. 19193/62. Heading G1U. In an apparatus for indicating undercharge of a storage battery 10 a voltage sensitive relay 26 in series with a switch 16 is connected across the battery, normally closed contacts 28 operated by the relay are connected in series with the switch and in parallel with the relay and connected in series with an indicator lamp 20, and a temperature compensating means consisting of a thermister 30 in parallel with a resistance 32 is connected in series with the relay to compensate at least partly for variations in the operating voltage of the relay with temperature. The arrangement is such that the voltage sensitive relay is energized on closing the switch 16 only if the battery voltage is above a predetermined amount, otherwise the contacts 28 remain closed and the indicator light is illuminated to show an under-charged condition- The apparatus is particularly applicable for use with a battery in the ignition circuit of an internal combustion engine having a generator 12 and a regulator 14 and as described may also include an arrangement for dissipating surface charge on the plates of the battery prior to making the test so as to avoid errors due to this cause. An additional set of contacts 34 operated by the relay are included, and a thermal switch 58 energized by the generator 12. With the engine running, the thermal switch 58 is closed, but the contacts 34 will be open. If the switch 16 is now opened to switch off the engine, the contacts 34 close and the surface charge on the battery plates discharges through the thermal switch, until this has cooled sufficiently to open, into the 75 watt resistor 38. With the surface charge thus dissipated, operation of the switch 16 will enable the true electrochemical condition of the battery to be determined.

Abstract: 596,519. Frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 28, 1945, No. 19347. Convention date, July 28, 1944. [Class 40 (v)] A detector for angle modulated oscillations comprises two series resonant circuits, oppositely mistuned with respect to a centre frequency, arranged so that the inductances have a common terminal, and the condensers have a common terminal coupled through a low impedance to an input circuit tuned to the centre frequency, means for rectifying the voltages developed across the inductances and differentially combining the rectified voltages. As shown in Fig. 1, series resonant circuits C1, L1 and C2, L2 are mistuned on opposite sides of the frequency to which the input circuit 6, fed from a limiter 1, is tuned. The common terminal of condensers C1, C2 is coupled through a low impedance condenser C3 to a low potential point on the input circuit. The junction of coils L1, L2 is connected to earth through byepass condenser 9<1>, while the voltages appearing across coils L1, L2 are rectified by diodes 10, 11 respectively, and an audio output taken off through chole 12. The capacity coupling C3 may be replaced by inductive coupling (Fig. 2, not shown). In a modification, Fig. 4, the coils L1, L2 are shunted by damping resistors R3, R4. In tuning this embodiment, the ganged condensers C1, C2 are adjusted to tune the series resonant circuits C1, L1 and C2, L2 to one side of the centre frequency, and the circuit C1, L1 is then tuned to the opposite side of the centre frequency by an auxiliary condenser C4. The discriminator may be fed through a concentric cable terminated by a resistance and connected to the input circuit through a blocking condenser (Fig. 6, not shown) or a coupling coil (Fig. 7, not shown). The discriminator may be used as a monitor for a frequency modulated transmission, when it is coupled to the output circuit of the transmitter. Specification 296,678, [Class 40 (v)], is referred to.

Abstract: 678,379. Electric filters. POSTMASTERGENERAL. April 13, 1951 [July 22, 1949], No. 19371/49. Drawings to Specification. Class 40 (viii). An electric wave filter comprises two or more sections connected in tandem, in which at least one of the sections has a cut-off frequency which is different from that finally required of the filter, and in which another section or sections is or are provided to produce a required sharp frequency cut-off. For example a lowpass filter may consist of an elementary lowpass section, whose cut-off is higher than that required, followed by one or a succession of band stop sections to give the necessary sharp cut-off. A high pass filter can similarly be made from a high-pass section and a number of band stop sections. A band stop filter can be made by connecting high-pass and low-pass filters of this character in tandem. The performance of the filter can be improved by the introduction of simple resistance attenuators between the sections. One or more of these attenuators can be replaced by constant impedance equalizer networks.
