Title: Improvements in fastening devices for doors and the like
IPC: E05C17/16
Filed: 1956-06-12
Abstract: 823,248. Door and like fastenings; stays for hinged articles. TANNEN, A. May 31, 1957 [June 12, 1956], No. 18189/56. Classes 44 and 65(1) A fastening device for a door or the like comprises an arm 1 pivoted at one end to a member 3 adapted to be mounted on the jamb post 4 of the door or the like and a sliding bolt 6 carried by a housing 5 adapted to be mounted on the door or the like, the bolt being so formed at its free end as to be slidably engaged with the arm in such a manner that as the door or the like is opened the arm is caused to pivot relatively to the jamb post, an abutment at the end of the arm limiting the sliding movement and hence the opening movement of the door, the bolt being disengageable from the arm when the door or the like is shut, and means to interconnect a lock 12 mounted on the door or the like with the bolt in such manner that operation of the lock causes withdrawal of the bolt. The bolt is loaded into engagement with the arm by a spring 7 and is disengaged by a knob 8. In the embodiment shown in Fig. 1 the arm 1 is pivoted about a horizontal axis and the weight of the arm normally maintains it in the vertical position shown. The head 10 of the bolt 6 is normally engaged in a groove 2 in the arm and when the door or the - like is opened the arm pivots relative to the member 3 and the head of the bolt slides down the groove until it reaches its end which forms the abutment, thus preventing the door or the like being opened any further; the head 10 of the bolt can be withdrawn from the groove in any position of the arm. The head 10 of the bolt is rounded and the outer side of the arm 1 is provided with a cam surface 11 adjacent its pivoted end so that after the bolt has been disengaged from the groove it can snap back into the groove on closing the door or the like. The lock 12 has a tongue 13 of a cylinder connected to a lever 14 which is connected by a link 16 to a triangular cam member 18 pivoted to the housing 5 and which bears against a projection on the rear side of the knob 8: when the cylinder of the lock 12 is turned by its key, the movement of the lever 14 causes the cam 18 to withdraw the bolt 6. In a modification the arm 1 is pivoted about a vertical axis and the groove is undercut so that the bolt head can only be withdrawn from the groove adjacent its pivoted end. In this modification a hole is provided in the arm adjacent its free end and a screw or pin inserted through this hole holds the bolt at the end of the arm so that the door or the like is held slightly ajar.

Title: Improvements in valves for automatic sprinkler systems
IPC: F16K1/20
Filed: 1930-06-13
Abstract: 356,317. Fire-extinguishing. LEWIS, L. M., 207, Church Road, Ardmore, Pennsylvania, U.S.A. June 13, 1930, No. 18198. [Class 47 (ii).] Relates to sprinkler systems of the kind wherein the distributing pipes B, Bl are normally filled with a non-freezing solution supplied under pressure by a tank T, and wherein a main water-supply valve is automatically opened when the solution supply becomes exhausted, and consists in providing a main valve casing -1 which comprises a chamber 2 and an auxiliary chamber 3 separated by a valve 17 which, when closed, holds the main water valve 10 closed by means of a lug 24. The water inlet 4 and auxiliary chamber 3 are connected by a pipe 25, so that byepassed water acts on the valve 17 to hold the water valve 10 closed. A drain pipe I from the auxiliary chamber 3 is larger than the byepass pipe 25, and is normally closed by a valve H, the latter being held closed by the solution pressure in tank T acting through the supply pipe D and connection F. When a sprinkler head C opens, solution flows out alone until the solution pressure falls to a point at which the valve H opens. This relieves the byepass pressure on the valve 17, allowing the main water valve 10 to open. The valve 10 is carried by a pivoted arm 12 and the valve 17 is counterweighted at 22 and comprises a resilient gasket 20 retained by a ring 21.

Title: Azo esters
IPC: C08K5/24
Filed: 1946-06-18
Abstract: Azo-esters, useful in the vulcanization of rubber, and of the general formula <FORM:0613317/IV(a)/1> (wherein R is a polyvalent and R1 a monovalent hydrocarbon, oxahydrocarbon or thiahydrocarbon radical or a corresponding nitro- or halogen-substituted radical, and x is a small whole number greater than one and equal to the valency or a corresponding nitro- or halogen-substituted radical, and x is a small whole number greater than one and equal to the valency of the R radical) are manufactured by oxidizing, e.g. with concentrated nitric acid or potassium permanganate, the corresponding hydrazo-esters obtainable by the process of the parent Specification.  Examples describe the oxidation of the products of the examples in the parent Specification.  The Specification as open to inspection under Sect. 91 comprises also the oxidation of the linear and cross-linked high molecular condensation products described in the parent Specification as open to inspection.  This subject-matter does not appear in the Specification as accepted.ALSO:Azo-esters, useful in the vulcanization of rubber, and of the general formula <FORM:0613317/IV(b)/1> (wherein R is a polyvalent and R1 a monovalent hydrocarbon, oxahydrocarbon or thiahydrocarbon radical or a corresponding nitro- or halogen-substituted radical, and x is a small whole number greater than one and equal to the valency of the R radical), are manufactured by oxidizing, e.g. with concentrated nitric acid or potassium permanganate, the corresponding hydrazo-esters obtainable by the process of the parent Specification. Examples describe the oxidation of the products of the examples in the parent Specification.ALSO:The vulcanization of rubber is induced often without heating, by the action of azo-esters of the general formula <FORM:0613317/V/1> wherein R is a polyvalent and R1 a monovalent hydrocarbon, oxahydrocarbon or thiahydrocarbon radical, or a corresponding nitro- or halogen-substituted radical, and X is a small whole number greater than one and equal to the valency of the R radical. The vulcanization may be effected by mixing the azo-ester with the rubber in a rubber mill, or mixing with a solution of rubber and applying the solution as an adhesive or coating composition, the formed rubber article or the rubber film obtained by the evaporation of the solvent becoming fully vulcanized by merely standing at room temperatures.  In an example, a solution of 2 : 2-(p : p-di-(hydroxyphenyl)-propane bis-(ethyl-azodicarboxylate) in benzine is added to a solution of crepe rubber, which is readily cured when evaporated at 60 deg. C.

Title: Method of forming a superconductive metallic film
Inventor: NEUGEBAUER CONSTANTINE ALOIS
IPC: C23C14/14
Filed: 1965-04-30
Abstract: A superconductive vanadium-gallium alloy film is formed on a substrate (e.g. of W, stainless steel, quartz, mica, MgO or sodalime glass) by disposing the substrate, V and Ga within an evacuable chamber, evacuating the chamber to a pressure of from 1 x 10-9 to 5 x 10-5 mms Hg, evaporating sufficient of the V to getter oxygen and oxygen containing compounds within the chamber, and thereafter co-evaporating the V and Ga and simultaneously co-condensing the evaporated metals on the substrate.  The V may be heated by electon bombardment or by induction heating.  A shield may be maintained between the V and the substrate during the gettering.  If the substrate temperature is above 500 DEG C. during the co-evaporation of V and Ga in an atomic ratio of 3 of V to higher than 1 of Ga then V3Ga is formed. The apparatus used is the same as that described in the parent Specification 1,057,048.

Title: A method of and apparatus for recording pulse spectra
Inventor: BOCLET DANIEL
IPC: H03M1/00
Filed: 1963-05-09
Abstract: 1,009,465. Electric selective signalling. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 9, 1963 [May 10, 1962], No. 18378/63. Heading G4H. [Also in Division H3] A train of pulses is recorded by converting each pulse into a train of identical signals 4 of duration determined by the amplitude of the pulse, and recording the train of signals on a flexible recording support 2, any newlyincident pulse not being so converted unless the signal train representing the last pulse has been recorded. In Fig. 1, the incident pulse is amplified at 8, and passed through a gate 9 only if its amplitude (as determined at 10) is above a certain minimum and if a gate 11 is open. Gate 11 is normally open, but is closed for a predetermined interval after each pulse is passed by gate 9 by means of a pulse generated by monovibrator 24 triggered by unit 10. The input pulse, when passed by gate 9, charges a small capacitance 14. The pulse generated by monovibrator 24 also allows a charging unit 22 to charge a large capacitance 16 to the voltage of capacity 14 in response to a signal from a comparator 15 comparing the two voltages. When the pulse from monovibrator 24 ends, capacitors 14, 16 are allowed to discharge, the latter through a unit 17 which produces a duration-significant pulse 18 dependent on the discharge time of capacitor 16. This pulse 18 gates clock pulses into a magnetic tape recorder 3. The motor of recorder 3 may be started only when an input pulse is passed by gate 9. The recording may be read off at comparatively high speed into a multi-channel selector to classify the original input pulses according to amplitude. Each train of signals from the magnetic tape 2 is fed to an integrator of the diode pump type which produces a staircase potential to charge a capacitor the discharging of which produces a pulse of amplitude representing that of the original input pulse. In the multichannel selector the pulse is converted into a duration-significant pulse which gates clock pulses into a counter which selects one of a number of memory elements and reads out the number in it, the number being returned to the element after unity has been added to it. Alternatively, the signal train from the magnetic tape 2 is fed (after shaping) direct to the counter in the multi-channel selector.

Abstract: 1,133,389. Feeding sheets. ADAMOVSKE STROJIRNY NARODNI PODNIK. 27 April, 1966 [10 June, 1965], No. 18390/66. Heading B6B. A mechanism for raising the pile table of a printing machine either in step-by-step movements during feeding of sheets or continuously to bring the top of a new pile to working position comprises a shaft 1 rotation of which raises the table, a continuously driven gear 7 rotatably mounted on the shaft, and means for intermittently or continuously coupling the shaft 1 to the gear 7. The gear 7 has pivoted thereto at 8 a member 9 with three arms 9<SP>1</SP>, 9<SP>11</SP>, 9<SP>111</SP>. A spring 13 normally holds the arm 9<SP>111</SP> against a pin 14 on the gear 7, in which position the arm 9<SP>1</SP> is held out of engagement with a ratchet wheel 2 freely mounted on the shaft 1 but coupled to a disc 6 fixed to the shaft through pins 3, 3<SP>1</SP> engaging a disc 4 of resilient material freely mounted on the shaft. Sensing of the level of the pile may close an electric switch causing an electromagnet 11 to be energized. The magnet 11 attracts the arm 9<SP>111</SP> so that the arm 9<SP>1</SP> is moved into engagement with the ratchet wheel 2 and the shaft 1 is driven to raise the table. The arm 9<SP>1</SP> remains in engagement with the ratchet wheel 2 and the table continues to rise until a stop 10 is pivoted into the path of the arm 9<SP>11</SP>, and unlatches the arm 9<SP>1</SP>. With the stop 10 remaining in the operative position, the arm 9<SP>1</SP> engages the ratchet wheel 2 for a part of a revolution every time the electromagnet 11 is energized by the sensing device, so that the table is now intermittently raised. By adjusting the stop 10 in the direction of arrows III, IV, the amount the table is raised at each actuation of the electromagnet 11 may be adjusted.

Title: Surge control device for centrifugal compressors
IPC: F04D27/02
Filed: 1958-06-11
Abstract: 893,086. Centrifugal compressors. GARRETT CORPORATION. June 11, 1958 [June 11, 1957], No. 18702/58. Class 110 (1). [Also in Groups XIII and XXIX] In a centrifugal compressor which, as shown, may be used in a vapour cycle refrigerator circuit, the rate of flow through the discharge passage 21 is sensed by a probe comprising orifices 80 and 81 facing upstream and downstream, respectively, the pressures developed at the orifices being applied through pipes 82, 83 to opposite sides of a diaphragm 60 to urge the diaphragm towards the left so as to close the end of a tube 64. When the rate of flow is reduced to a value at which surging in the compressor is imminent, the resultant reduction of the difference between the pressures developed at the orifices 80, 81 allows a spring 70 to move the diaphragm 60 away from the tube 64. Vapour from the discharge passage 21 then flows through the tube 64 to a chamber 90 and thence through the hollow stem 36 of a valve 35 to the compressor inlet 14. When this flow occurs, a constriction 53 in this flow path raises the pressure in chamber 90 above the pressure at the inlet 14, the resultant force on a diaphragm 45 opening the valve 35 against the action of a spring 51. Vapour is then returned from the refrigerator condenser 12 to the inlet 14 by way of the valve 35 to increase the flow through the compressor sufficiently to prevent surging.
