Patent GB-216947-A (GB)
Abstract: 216,947. Automatic Telephone Manufacturing Co., Ltd., Gillings, C., and Passmore, W. O. March 7, 1923. Automatic exchange systems; metering.-In a multi-exchange system in which a register-controller translates the first three letters of the wanted exchange into a routing number, the meter Z is connected to a single or double impulsing lead according to the energization or non- energization of a marginal relay 57 over an auxiliary wiper 114 of the register-controller in series with the switching relay 53 which controls the release of the register-controller. A timecontrolled switch S causes repetition of metering and finally effects release after a definite interval. Additional marginal relays are employed in a system divided into more than two zones. Specifications 193,694, 194,427 and 194,580 are referred to. Operation of register-controller. The switch F operates like a group selector in response to the first digit and selects an idle register-controller (partially shown in Fig. 2), which receives the remaining digits and controls the setting up of the connection over leads 50, 51. The switching relay 113 energizes and connects lead 62 over an additional wiper 87 of the switch F and wiper 114 to earth or earth through a resistance r according to the zone of the wanted exchange. Relay 53 energizes, locks over a resistance r<1> and disconnects the switch F and the register-controller. Marginal relay 57 is such that it does not energize in series with resistance r, but once energized, it is held over resistance r'. Metering. Upon reversal of current when the called subscriber replies, polarized relay 17 energizes at the next closure of contact 95 by start cam 96, and meter Z is operated once or twice over a circuit 107, 105 and springs 112 or 103. The metering circuit is opened by stop relay 59 when stop cam 99 closes spring 108. Time-controlled metering and release. Stop relay 59 also connects up the driving magnet R of the switch S, which moves one step each halfminute, and after 2¢ minutes, a warning tone is sent from lead 122 over wiper 1. After 3 minutes, repeat relay 124 energizes over wiper 2 and springs 95, locks and completes the metering circuit at 126, relay 59 still being operated. Stop cam 99 short-circuits relay 124, which, before falling back, operates magnet R over armature 130 and springs 108 to prevent earthing of left spring 95 over wiper 2. After 6 minutes, wiper 4 removes earth at the succeeding switch from the test wire 41 to initiate release, preliminary warning tone being sent from lead 122. Release of relay 53 connects up magnet R over wiper 3 and restores the switch S.

Title: Improvements in or relating to terminations for ultra-high-frequency electromagnetic wave transmission lines
IPC: H01P1/26
Filed: 1947-08-07
Abstract: 628,928. High-frequency transmission lines. SPERRY GYROSCOPE CO. Aug. 7, 1947, No. 21715. Convention date, July 30, 1943. [Class 40 (viii)] An energy-absorbing termination for a highfrequency transmission line comprises a portion of line having material for absorbing energy distributed along its length and having its cross-section changed continuously or in steps so that the characteristic impedance decreases from the value at the input end to near zero at the opposite end. In the example shown of a coaxial construction the inner conductor 13 includes resistive material to absorb energy and the outer conductor 14 tapers in an exponential curve. For ease in manufacture the curve may be approximated by successive short cylindrical sections of diminishing diameter. If the length of these sections is only of the order of one eighth of the operating wavelength no substantial difference appears in the operation of this modification. Alternatively the outer conductor may be a cylinder and embody resistive material while the inner conductor expands in cross-section to the dead end.

Abstract: The invention comprises fluorocarbon aldehydes of the formula CnF2n+1CHO and the corresponding fluorocarbon aldehydrols of formula CnF2n+1CH(OH)2, where n has the value 1 to 17.  The aldehydrols may be prepared by reducing an acid CnF2n+1COOH with LiAlH4: dehydration of the aldehydrol, e.g. with concentrate sulphuric acid or P2O5, affords the free aldehyde, which must be stored dry and at low temperature.  The acids CnF2n+1COOH may be prepared by hydrolysis of either CnF2n+1COF or CnF2n+1 CONH2, the former being prepared by electrolysis of a mixture of liquid hydrogen fluoride and the acid CnH2n+1COOH, and the latter being obtained by treatment of the acid fluoride with ammonia.  The diacetates, e.g. CnF2n+1CH(OAc)2, may be prepared from the aldehydrols.  Treatment of the aldehydes, e.g. C3F7CHO, with a Grignard reagent, e.g. MeMgI, affords an alcohol, e.g. C3F7CHOH.CH3.  A example is given of the preparation of C3F7CH(OH)2 and C3F7CHO.

Title: Improvements in or relating to plastic product and process of manufacturing same
IPC: C08L89/00
Filed: 1945-08-29
Abstract: Proteins are prepared from blood by precipitation from the plasma remaining after the separation of the corpuscles by centrifugation or sedimentation.  Fibrinogen is prepared by cooling the plasma to 0 DEG C. or lower and adding an alcohol which may be methanol, ethanol or butanol or a water-miscible ketone sufficient to constitute 5 to 15 per cent by volume of the plasma. The pH and ionic strength of the plasma are preferably adjusted; the higher the ionic strength and pH the greater the concentration of alcohol required to precipitate the fibrinogen, and the higher the alcohol concentration the lower the temperature at which separation can be made between fibrinogen and other proteins.  For the precipitation of fibrinogen the pH may initially be maintained at 6.0 to 7.8, and the ionic strength may be 0.005.  Gamma globulin is obtained by cooling the remaining plasma to -5 DEG  C. and increasing the alcohol &c.  Concentration to 25 per cent, the pH remaining as before.  Alpha and beta globulins are obtained by increasing the alcohol &c. concentration to 40 per cent, the temperature remaining at -5 DEG  C., and adjusting the pH to 5.5 to 6.0.  By lowering the temperature to -15 DEG  C. and/or the pH to 4.7, the alcohol &c. concentration remaining the same, the albumins are precipitated.  The precipitant may be added to the protein solution directly or by diffusion through a semipermeable membrane. In an alternative procedure fibrinogen may be obtained by extraction from a solid protein mixture which may be precipitated and dried, and the fibrinogen extracted therefrom and reprecipitated.  The Specification describes the use of fibrinogen with or without other proteins for the preparation of plastic compositions (see Group V). Specification 669,461 is referred to.
