Title: Improvements in or relating to electromagnetic relays
Inventor: MYATT EDWARD RONALD
IPC: H01H51/28
Filed: 1961-09-21
Abstract: 957,454. Electrically released switches. STANDARD TELEPHONES & CABLES Ltd. Sept. 14, 1962 [Sept. 21, 1961], No. 33871/61. Heading H2B. A sealed magnetic reed contact unit 1 across the polepieces 2a, 2b of a permanent magnet 2 is controlled by current pulses in a winding 3 and retained in the closed position by the permanent magnet. A pulse in the winding 3 which produces a flux in opposition to that of the permanent magnet results in repulsion of armatures 5a, 5b which are pivoted at 6a, 6b. Springs 7a, 7b move the armatures 5a, 5b away from the polepieoes 2a, 2b and the flux from the armatures and the permanent magnet passes through the reed contacts to effect closure. The springs retain the armatures away from the polepieces until a reverse pulse in the winding 3 causes their attraction by the polepieces and the permanent flux is diverted from the contact reeds which open under their inherent spring bias. Two such devices may have a common winding and may have common armatures (Fig. 5, not shown).

Title: An improved driving mirror
IPC: B60R1/02
Filed: 1958-10-25
Abstract: 870,285. Look-out reflectors for vehicles. RUSHFORTH, C. Jan. 25, 1960 [Oct. 25, 1958], No. 34209/58. Class 103(2). A driving mirror, mounted on a vehicle wing for rotation about a vertical axis is held in a rear-viewing position by a spring, remote control means in the form of a Bowden cable being provided, operable from inside the vehicle, to rotate the mirror against the urge of the spring to a position angularly displaced from the real viewing position, for viewing approximately at right angles to the major axis of the vehicle. Clutch means are provided to enable the mirror to yieldably rotate when struck and then, if only slightly rotated, to return to the normal rear-viewing position. The mirror carrying arm (not shown) is secured to the shaft 15, Fig. 8, of an upper clutch member 14, normally engaged with a lower clutch member 24, Figs. 4 and 9, whose shaft 23 engages in a bore coaxial in the member 14. Both members 14, 24 are rotatable in a cylindrical housing 10, Fig. 1, having a threaded tubular extension 11 passed upwardly through a hole in the vehicle wing and secured by a nut 12. The lower end of the shaft 23 is supported by a ball bearing 46 Fig. 6, in a closure member 44 for the bottom of the housing 10. A compression spring is disposed around the shaft 15 between a surface 17 of the member 14 and the interior upper wall of the housing, through which the shaft 15 passes. A coiled torsion spring surrounding the bottom of the shaft 23 is connected between a hole 40 in the lower surface of the clutch member 24 and a hole 43 in the member 44. The lower surface of the clutch member 24 has a recess 35 therein providing two end stops 37 and 38. By rotating the member 44 relative to the housing the torsion spring also rotates the clutch member 24 until one end stop abuts a screw 36 in the housing. Further rotation of the member 44 then stresses the torsion spring which stress may be selected by a screw 47 in the housing engaging one of the peripheral notches 48a, b, c, &c., in the member 44. The casing of a Bowden cable is secured in a threaded hole 32 in the housing and the cable has an anchor part engageable in a bore 25 in the clutch member 24, which also has an annular groove 34 to receive the cable. Clearly by pulling the cable and securing it in various, positions, the mirror is rotated away from the rear-view position against the action of the torsion spring. Once the cable is released the mirror will return to the rear-view position corresponding to the end stop. The angular movement is limited by the other end stop of the recess 35. If the mirror is accidently struck the clutch part 14 can yield against the compression spring and then return to the engaged position if the relative angular displacement is less than 90 degrees.

Patent GB-985383-A (GB)
Title: Improvements in or relating to light sources
Inventor: GUTHRIE DAVID GRAHAM
IPC: C09K11/02
Filed: 1962-09-08
Abstract: A method of coating a surface, e.g. a glass bulb with a phosphor comprises the steps of first dusting the surface with the phosphor, then coating the surface with a solution of ortho phosphoric acid, providing excess phosphor to adhere to the acid, and removing surplus phosphor.  The method is said to give a thin even coating to surfaces of awkward shape, e.g. small tritium- or trypton-activated sources. In the examples, the glass bulb is first cleaned with 10% hydrofluoric acid, washed and dried, then powdered with the phosphor. The bulb is then filled with phosphoric acid in solution in acetone or preferably di-ethyl-ether and then emptied and the remaining solvent rapidly evaporated in a hot air current.  Phosphor powder is then poured in and the bulb shaken to distribute it evenly, the excess powder tipped out, and the bulb oven-baked to convert the ortho to pyro phosphoric acid.

Filed: 1956-11-15
Abstract: 842,997. Refrigerating. MIKULA, J. Nov. 15, 1956 [Nov. 18, 1955], No. 34927/56. Class 29 [Also in Group XXVI] The medium supplied to the inlet of a compressor, preferably a compressor forming part of a gas turbine plant, is cooled by an absorption cooling process comprising a secondary coolant for cooling the medium to be compressed, an evaporator in which the secondary coolant is cooled by a primary coolant and an expeller in which the primary coolant is expelled through the heat available at the compressor outlet or in plant associated with the compressor by an auxiliary heattransfer medium such as water under pressure or oil. A secondary coolant e.g. brine, is cooled in an evaporator 1 by a primary coolant e.g. ammonia. The secondary coolant cools the air sucked in by the compressor 12 in a heat exchanger 2 consisting of tubes of small diameter. The primary coolant leaving the evaporator 1 passes to an absorber 3 where it is absorbed by a poor solution. A pump 4 forces the rich solution from the absorber 3 into the expeller 5 where it is expelled by heat from an auxiliary heat-transfer medium such as water under pressure as preferably a substance having a high boiling point such as oil or tetra-cresolsilicate. The heat-transfer medium is heated in a heat exchanger 6 by the turbine exhaust gases. The vapour from the expeller 5 passes through a condenser 9 and throttle valve 10 to the evaporator 1. The poor solution is passed back to the absorber 3. The cooling temperature may be adjusted by bypass valves 11 and transfer devices 14, or by throttle 10. The heat for the heat exchanger 6 may be obtained from steam or flue gas-in a combined steam and gas pass. The working medium may also be cooled between the stages of the compressor.

Abstract: 1,193,045. Hydropneumatic suspensions. AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT. 25 July, 1968 [12 Sept., 1967], No. 35487/68. Heading B7D. [Also in Division F2] In a vehicle suspension two pumps 1 each derive liquid from a common reservoir 4, one pump feeds two rear-wheel suspension units A and the other two front-wheel units B, and all four units have a return connection 9, 11 to the reservoir. Each unit is a self-levelling hydropneumatic support (see Division F2) in which a piston with a hollow piston-rod has a flexible seal in its cylinder normally above an aperture in the piston-rod. Excessive extension of a piston brings this aperture above the seal and in so doing opens a connection between the associated cylinder and the return line 9, 11 to the reservoir 4, thus producing a pressure fall which effects a corrective inward movement of the piston. The means connecting the suspension units to their respective pumps and to the common reservoir also connects the two front units together and the two rear units together: this provides an anti-roll effect, which supplements the action of the usual torsion spring anti-roll bar.

Title: Improvements in and relating to water-softening apparatus
IPC: C02F1/42
Filed: 1930-11-25
Abstract: 368,297. Softening water. REYNOLDS, W. P., 32, St. Peter's Square, Ravenscourt Park, London. Nov. 25, 1930, No. 35509. [Class 46.] A water-softening apparatus of the baseexchange type having a container 1 for the softening medium 3, e.g. natural or artificial zeolite, and a vessel 14 for the regenerating solution connected with the container 1 through a valve-controlled pipe, has a hand-operated main multi-way cock 12 and several auxiliary cocks so arranged and connected that they are adapted to control the flow of water through the apparatus to carry out the operations of softening, regenerating, cleansing and back flushing in such a manner that neither the regenerating solution nor water which has passed through the softening bed in the direction opposite to the direction of flow when softening passes through the main cock. In the apparatus shown the container 1 and the vessel 14 are connected by a siphon 15, 16 having a cock 18. During the softening operation water flows by way of a water-supply pipe 26, pipes 25, 22, the cock 12, a pipe 11 to a distributing pipe S, through the bed of softening material 3 and filtering material 2 and thence through a collecting pipe 9, a pipe 11<1>, the cock 12, a pipe 23, a cock 27 and pipes 28, 29 to a storage cistern. To regenerate the softening material the necessary quantity of regenerating material, e.g. common salt is placed in the vessel 14, the cock 27 is closed and the cock 18 is opened so that water passes up through the siphon pipes 15, 16 into the vessel 14 until the vessel 14 is full when the cocks 18, 12 are closed. When the salt has dissolved the cock 18 and a bib cock 13 on the pipe 11<1> are opened so that the salt solution siphons out of the vessel 14, any impurities contained in the salt remaining at the bottom of the vessel, and runs through the bed and is discharged through the cock 13 into a funnel 31 on the end of a pipe 32 connected to a waste pipe 21. When the flow of salt solution through the cock 13 ceases the cock 12 is set so that water again passes through the pipe 8 thereby forcing salt solution out through the cock 13. The bib cock is provided with two bores of different cross sections so that it can be set to discharge at different rates. For back flushing the valve 18 is opened and the cock 12 is turned so that water flows by way of the pipes 22, 11<1>, 9 through the bed 3 in the reverse direction and is forced up through the siphon 15, 16 into the vessel 14 carrying with it dirt &c. which is deposited on the bottom of the vessel 14, the water overflowing into a pipe 20 connected to the waste pipe 21. The cock 27 need not be closed during the back flushing. The pipe 9 is surrounded by a tube or bridge of gauze 10 and the pipes 8, 9 have flanges for connection with flanges or bosses on the apertures of the container so that the pipes may be readily removed.
