Filed: 1935-09-19
Abstract: 446,802. Automatic control systems. STEWART, F. C., 150, Helen Street, Govan, Glasgow. Sept. 19, 1935, No. 25965. [Class 38 (iv)] Temperature.-A vehicle heating and ventilating plant comprises an air heater 3, 4, supplied with heating medium and a fan or fans 2 operating in association therewith, a battery and a dynamo (driven only when the vehicle is in motion) as energy sources for the fans, a thermal or pressure responsive device 17 controlling contacts 19 in the motor-battery circuit to stop the fans should the supply of heating medium fail, and a thermostat 10 responsive to air temperature within the vehicle. The last initiates or augments the supply of heat energy, by closing contact 11, and connects the fan motor 1 alternatively in circuit with the battery or the dynamo by closing contact 12 and opening contact 13. The action is such that the fans do not operate when the internal air temperature is low and heating medium is not available, or when the vehicle is stationary and the said temperature is high, but are operative when the said temperature is low and heating medium is available, and also when the vehicle is in motion and the said temperature is high. A hand switch 20 enables the fans to be driven from the battery when desired. The air heater may comprise a main heater 3 with direct thermostatic control 7 as shown and an auxiliary heater 4 supplied through a valve controlled by the contact 11.

Patent GB-626073-A (GB)
Title: Improvements in or relating to hydraulic master cylinders
IPC: B60T11/16
Filed: 1946-08-29
Abstract: 626,073. Master cylinders. COATALEN, L. Aug. 29, 1946, No. 26036. Convention date, Nov. 3, 1945. [Class 103 (i)] [Also in Group XXVI] A hydraulic master cylinder comprises a cylinder having a pressure outlet connection, a plunger slidable through two annular packings fitted within the cylinder, and a reservoir connection leading into a space between the packings, the plunger being formed with a longitudinal passage communicating at its rear end with said space and provided at its front end with a valve member which is closed to isolate the passage from the cylinder pressure space during the working stroke of the plunger. In one form, Fig. 1, a plunger 17, acted on by a return spring 33 is slidable in collars 6 and 11 located in a bore 3 of a cast cylinder 1 having a working chamber 2 communicating with an outlet port 30 through a delivery valve comprising a member 32 acted on by the spring 33 and formed with a number of holes 32a normally closed by a flexible cup 34. Sealing rings 8 and 12 of rubber or other elastic material are disposed in grooves of greater axial width in the collars 6 and 11, and further sealing rings 10 and 13 are provided between the collars and the bore 3. The collars are separated by a tube 15 and a washer 20 and are retained in position by a circlip 14. The retracted position of the plunger is determined by a circlip 18 which engages the washer, and in this position the chamber 2 is in communication with a liquid reservoir through grooves 21 in the plunger, holes 16 in the tube 15, a passage 5 and a pipe connection 4. The chamber 2 may also communicate with the reservoir through passages 22 and 25 in the plunger and a valve 26 normally held seated by a spring 27. Initial movement of the plunger causes the ends of the grooves 21 to overlap the collar 6, and pressure is then built up in the chamber 2 to deflect the cup 34 so that liquid flows through the outlet port. On the return movement of the plunger, the valve member 32 unseats to allow the return flow of liquid to the chamber 2. If the movement of the plunger is sufficiently rapid to locate a depression in the chamber 2, the valve i6 unseats to allow make-up liquid to flow from the reservoir. In a second form, Fig. 2, the grooves 21 are omitted, and the valve 26 is normally held open by a light spring 28a and seated by the pressure in the chamber 2 during the working stroke of the plunger. In a third form, Fig. 3, the valve 26 is normally held seated by a spring 27 but is fitted with a transverse member 38 which is engaged by a shoulder 39 on the cylinder to unseat the valve as the plunger reaches the retracted position.

Title: Improvements in or relating to telegraph receivers
Inventor: GOULD WILLIAM FREDERICK
IPC: H04L25/45
Filed: 1948-10-08
Abstract: 650,917. Code telegraphy. STANDARD TELEPHONES & CABLES, Ltd. Oct. 8, 1948, No. 26288. [Class 40 (iii)] [Also in Group XL (c)] An electric oscillator comprises a frequency determining circuit, a source of direct current having a maximum value corresponding to the maximum value of the alternating current produced by the oscillator, means for passing the direct current through a part of the frequency determining circuit to stop the oscillator, and means for disabling the source of direct current in order to bring the oscillator into operation at a fixed point in the alternating current cycle. As shown, the oscillator comprises a pentode valve 1 having the primary 3 of a transformer connected in its anode circuit and one side of the tuned circuit consisting of secondary 4 shunted by a capacitor 9 connected through resistors 7 and 8 to the control grid, the other side being connected direct to the cathode. A valve 10 using a low anode voltage is connected across the tuned circuit and is arranged to pass a current corresponding to the maximum alternating current produced by the oscillator, this stopping the oscillator. To start the oscillator the valve 10 is biassed to cut-off as by taking the potential from the anode of a control valve rendered conductive or a relay switching the required potential from a suitable source, and the direct current through the coil 4 begins to decay building up a potential across the coil 4 which is equivalent to one half-cycle of the oscillator alternating current, the oscillator then continuing to function in the normal manner. Pulses may be produced by arranging that the grid voltage overswings violently the oscillator valve to produce a substantially square waveform which may be passed through a differentiating circuit to produce a succession of positive or negative pulses, the unwanted pulses being eliminated as by rectifiers. The oscillator may also be arranged to stop at the correct point on the cycle by arranging that the control valve is operated under the control of pulses generated by the oscillator. In an alternative arrangement, Fig. 2 (not shown), the principle is applied to a resistance-capacity oscillator.

Patent GB-1176969-A (GB)
Title: Improvements in or relating to Stress Gauges
Inventor: GIBBS JOHN ROBERT
IPC: G01L13/02
Filed: 1967-09-18
Abstract: 1,176,969. Stress and pressure gauges. NATIONAL RESEARCH DEVELOPMENT CORP. Aug.29, 1968 [Sept. 18, 1967; June 4, 1968], Nos.42325/67 and 26496/68. Headings G1L and G1W. A stress gauge for measuring stress within a body of material comprises a readily deformable element 1 adapted to be embedded in the body, means 7, 9, 10, for controlling the deformation of the element 1 under stress so as to cause it to behave in respect of such deformation in the same manner as a separate specimen 10 of the material that is dimensionally similar to the element 1 and indicating means responsive to the deformation of the element. The control means comprises a framework 9 in which the specimen 10 is mounted and stressed by hydraulic fluid filling a stress sensing cell 1 embedded in the body, a control cell 7 and a communicating pipe-line 6. The hydraulic pressure tends to elastically distort the components of the system and so to change its volume, which change is counteracted by a compensator 15, which also provides a measure of the pressure and therefore of the stress. In the compensator 15, Fig. 2, the hydraulic pressure is communicated to bellows 45, 49 acting on a pivoted lever 42 and a flexure bar 50 respectively. Increase in pressure flexes the bar 50 and through a rod 48 compresses a bellows 46, communicating with a temperature compensating bellows 47 through a capillary tube 56, to displace a mercury pellet 57. A screw 44 is rotated to raise the lever 42 until the mercury pellet 57 returns to its original position and the bellows 45 are compressed to eject the small amount of fluid necessary to counteract the elastic distortion of the components of the stress gauge so that the amount of rotation of the screw 44 is a measure of the pressure and it can be calibrated in terms of stress in the body. A method of calibrating the compensator for a particular stress gauge is described and servo-mechanism operating in response to movement of the pellet 57 may be coupled to the screw 44. Modifications to measure components of stress in two or three co-ordinate directions are suggested.

Abstract: An antibiotic active against cancer, tuberculosis, rheumatism or syphilis is obtained by culturing pseudo proteus immunitatis- or anti - carcinomatosa, anti - tuberculosa, anti-rheumatica or anti-syphilitica in a meat infusion broth at 30-70 DEG  C. Preferably the meat infusion broth contains a small quantity of tissue of the respective disease, e.g. cancer tissue. The broth is prepared from infusion of fresh calf meat, peptone and sodium chloride and has a pH of 7.0.  Incubation is for 2 to 7 days, preferably at 30-37 DEG  C.  The broth is filtered, adjusted to pH 6.5 and extracted with butyl alcohol.  The extract is adjusted to pH 3.0, the solvent removed from the resulting solution and the residue purified by crystallization from methanol.  The antibiotic, which is of unknown constitution, is used medicinally (see Group VI).  The microorganism (described) is isolated from the blood of patients suffering from the disease or from the earth in which the bodies of individuals having the respective diseases have decomposed.  Blood from a patient is mixed with aqueous sodium citrate, the plasma separated and cultivated in the above sterile meat infusion broth. The desired bacteria are isolated from the mycelium appearing on the surface of the liquid.  In the case of the earth from the dead bodies, the earth is cultured on agar at 37 DEG  C. and the desired bacteria are selected from the mycelium which grows thereon.  The selected bacteria are cultivated in sterile meat infusion broth of pH 7 for 30-37 DEG  C. for 1 day, filtered and the filtrable form of the immune bacteria cultivated in sterile meat infusion broth to produce the antibiotic.ALSO:An antibiotic active against cancer, tuberculosis, rheumatism or syphilis obtained by fermentation of pseudo protens immunitatisanti carcinomatosa, anti-tuberculosa, anti-rheumatica or anti-syphilitica (see Group IV (b)) is put up in aqueous solution for injection or mixed with petroleum jelly to form an ointment.
