Title: Improvements in or relating to radio receivers
IPC: H03J5/14
Filed: 1938-06-17
Abstract: 517,420. Electric control systems. COOPER, A. H. June 17, 1938, No. 18066. [Class 40 (i)] In a push-button or other servo operated radio receiver covering several wave ranges and in which the same motor is used for operating the tuning and wave change mechanisms, the operation of the button for a station outside the range to which the receiver is tuned causes the motor to be coupled first to one. only of the mechanisms and after adjustment of that mechanism to the others. As shown, the depression of one of the buttons closes springs 14, 15 which complete circuits via the control drums 8, 11 for the motor 1 and the clutch magnets 22, 23, one of the latter, say 22, being arranged to operate first and open the circuit of the other. The motor then drives the drum 8 and the tuning condenser (not shown) to the position indicated by the button, whereupon clutch magnet 22 is released and clutch magnet 23 is operated and the motor, which continues to run, drives the drum 12 and the wavechange switch to the position indicated by the button. The motor and clutch magnet are then de-energized. The motor may also be energized by switches 25, 26 in series with a clutch magnet 24 for controlling volume level. In a modification Fig. 2 (not shown), in which there is no provision for volume control the clutches act by moving the motor shaft axially. In a further modification, Fig. 1 (not shown), the motor is normally geared to one drum and drives this drum when energized through a resistance. When energized direct however the armature in known manner moves axially against a spring to gear the motor to the other drum. In all cases a given push button can be associated with stations in different wave ranges with the help of plugs and sockets 19...21. The control drums can. be replaced by discs-and the wave-change switch by an adjustable coil turret. The push button &c. may have volume controlling contacts, and may be replaced by relay or switch contacts controlled, e.g., by a telephone dial. Reference has been directed by the Comptroller to Specification 497,774.

Filed: 1967-04-20
Abstract: 1,145,796. Hydrohalogenating olefins. MARATHON OIL CO. 20 April, 1967 [20 April, 1966], No. 18250/67. Heading C2C. Olefins are hydrohalogenated by contacting a hydrogen halide with an olefin in the presence of a catalyst containing the oxide of a metal of Group IV of the Periodic Table. Titanium dioxide is preferred but germanium dioxide and zirconium oxide are also specified. It is preferred to use olefins having a boiling point below 600‹ C., olefins having from 2 to 20 carbon atoms being especially suitable, but olefins outside this range may be used by varying the pressure conditions to maintain the olefin in the vapour phase. The catalyst is desirably in the form of a fixed bed, and the feed rates of reactants are generally from 5 to 100 volumes per volume of catalyst per minute.

Title: Improvements in the treatment of textile materials
IPC: D01C5/00
Filed: 1947-07-10
Abstract: Mixtures comprising wool fibres and cellulose ester or ether fibres are treated with hydrochloric acid vapour in the presence of a swelling agent for the ester or ether, preferably between 50-100 DEG C.  The swelling agent may be present in the material prior to its contact with the acid vapour, but preferably a volatile swelling agent is employed and its vapours brought into contact with the material in admixture with the hydrochloric acid vapour.  Suitable swelling agents are acetone, methyl ethyl ketone, diacetone alcohol, dioxane, glycol monoalkyl ethers, and lower fatty acids such as formic, acetic and propionic.  The action is continued until the fibre has been rendered so friable as to be removable by mechanical means, shaking, suction, sifting and the like.  Finally the material is washed and dried.  The treatment may be carried out in a perforated drum enclosed in a suitable casing, the vapour being introduced through a hollow axle.  Rags, waste yarn and tailor's cuttings may be treated.  The process may also be used to remove cellulose acetate from a woven or knitted fabric.  The process is particularly applicable to cellulose acetate fibres in admixture with wool, but other derivatives such as cellulose acetate propionate, cellulose propionate, cellulose butyrate and ethyl and benzyl cellulose may be treated.

Title: Improvements in tubulous vapour generating and vapour heating units and an improved method of regulating superheat and reheat temperatures
IPC: F22G5/04
Filed: 1956-06-14
Abstract: 834,012. Water-tubs steam boilers; superheaters. BABCOCK & WILCOX Ltd. June 14. 1956 [June 15, 1955: Nov. 30, 1955], No. 18368/96. Classes 123(2) and 123(3) In a water-tube boiler comprising cyclone furnaces 24, of the type disclosed in Specification 598,141, discharging gases into a secondary furnace 42 whence they flow through a slag screen 44 and upwardly in a radiation chamber 10 then through a lateral pass 92 and a downpass 74, the end of the lateral pass adjacent the chamber 10 locates a reheater including a section 134 consisting of widely spaced tube platens heated mainly by radiation and a section 138 of narrowly spaced convectionheated platens whilst in the other end of the pass 92 and in the downpass 74 are disposed secondary superheater sections 120, 114, a primary superheater section 106 and an economizer 150, 152. An attemperator 110 is disposed between the superheating stages. To enable the temperature of the gases entering the lateral pass to be adjusted a fan 160 is provided to withdraw flue gas from the bottom of the downpass and deliver it into the chamber 10 through ports 168. The radiant and convection sections of the reheater are so proportioned that the reheated steam temperature remains constant over a wide load range. In operation at full load there is maximum of superheat attemperation and gas recirculation which are both reduced as the load is decreased. Since a large proportion of the reheater is radiantly heated and the superheater is disposed downstream thereof, the tendency of the decreasing gas recirculation to reduce the steam heating effect is much greater in the superheater than in the reheater. The tendency of the reheat temperature to fall more than the superheat temperature with decreasing load is thus offset. In a modification, the reheater includes a radiant section disposed in the top of the radiation chamber and a convection section in the inlet of the lateral pass. Specification 526,825.also is referred to.

Title: Means for measuring a torsional stress in a shaft of magnetostrictive material
IPC: G01L3/10
Filed: 1958-06-10
Abstract: 829,399. Measuring torsional stress. ALLMANNA SVENSKA ELEKTRISKA A.B. June 10, 1958 [June 26, 1957; May 13, 1958], No. 18466/58. Class 37. The torsional stress in a shaft of magnetostrictive material is measured with two similar magnetic cores having salient poles facing the shaft, displaced axially by a fixed distance and staggered circumferentially by half a pole spacing; when the shaft is rotating, the magnetic paths from any one pole and the two adjacent poles on the other core become unequal in reluctance due to torsional stress, and an A.C. signal fed into a coil on the one pole gives unequal pick-ups in coils on the other poles. In Fig. 1 one core 10 carries poles with energized windings 15, 16, 17, 18 and the other core behind it (not visible) carries poles with pick-up windings 25, 26, 27, 28. When the shaft 9 is at rest coil 16 (say) produces equal pick-ups in coils 26 and 27 and with the arrangement of Fig. 3 no output results from the circuit. The meter can be calibrated to read the torsional stress as a function of the unbalance current. In a preferred form (Fig. 7) the energized core has a pick-up core on each side of it, the eight windings thereof 25-28, 35-38 being connected as shown. For measuring stress in a hollow shaft the salient poles are mounted on a solid core situated inside the shaft (Fig. 5, not shown). The cores can be divided into two or more portions and need not be complete circles as long as there are at least three poles on the energized core and at least two on each of the pick-up cores. The whole device is magnetically shielded.

Title: Improvements in gyro compasses
IPC: G01C19/38
Filed: 1934-06-22
Abstract: 433,494. Gyroscopic compasses. SPERRY GYROSCOPE CO., Ltd., Great West Road, Brentford, Middlesex, and HARDING, W. G., 28, Allan Way, North Acton, London. June 22, 1934, No. 18515. [Class 97 (iii)] In a gyroscopic compass, the phantom element is rotated relatively to the azimuth gear by correction mechanism so that the azimuth gear is correctly orientated notwithstanding the speed, course, and latitude error of the gyro axis and phantom element. In the form shown in Fig. 1, a crosshead 1 is slidably mounted in N-S bearings 2, 2<1>, on the azimuth gear 3. In the slot of the crosshead 1 is mounted a slide block 4 pivotally supporting a member 5 which is fixed to an axially adjustable rod 6 mounted in fore and aft bearings on the compass spider 7. When the rod 6 is axially adjusted by the screw 8 in accordance with the ship's speed and latitude and the pivot of the member 5 consequently moved from concentricity with the vertical axis of the compass, change of course of the ship and therefore turning of the rod 6 relatively to the azimuth gear 3 causes motion to be imparted to the block 4 and in turn to the crosshead 1. The latter has a forked arm 10 engaging a pin 12 on the phantom ring 13, which is accordingly turned relatively to the azimuth gear 3 when the crosshead 1 moves in a N-S direction. The crosshead 1 may be replaced by a pivoted slotted lever or a cam may be used to move the crosshead. In a modification, Fig. 2, a plate 15 pivoted to the spider 7 is tilted by the adjusting means 19 in accordance with the ship's speed and latitude and a spring-urged lever 16 pivoted to a bracket 17 carried by the azimuth gear 3 has a terminal roller running on the tilted plate 15. As the ship changes course the lever 16 is rocked and adjusts through the toothed sector 20 and rack 21 the angular position of the phantom ring 13 relatively to the azimuth gear 3. Specification 15679/11, [Class 97 (iii)], is referred to.

Abstract: 836,330. Filters. BENDIX AVIATION CORPORATION. June 10, 1958, No. 18541/58. Class 46. [Also in Group XXII] Unfiltered liquid entering at 5, Fig. 1, passes inwards through filter tubes 18 closed at the bottom by a disc 9 and surmounted at the top by an open-topped header 13 which rests on projections 19 on the tubes and has the upper ends of the tubes secured to its discportion 20. Filtrate leaves at 7. Each tube 18 is made by wrapping flattened wire around a cylindrical or conical mandrel, sintering the wire whilst in position, rolling or swaging the assembly to expand the winding slightly and compact the metal and finally withdrawing the mandrel. The swaging step may be followed by re-sintering. The wires may be coated initially with low-melting-point metal (e.g. copper) or alloy and sintered at a lower temperature. After sintering and removal of the mandrel the tube is processed to a finished form. In Fig. 2, the tubes 18 have their ends accommodated in holes provided in plates 26, 27. A cylinder 28 of the same material as the tubes extends between the plates, forming a chamber 29 about the tubes. Unfiltered liquid entering at 23 passes outwards through tubes 18 into chamber 29 and also inwards through cylinder 28 into chamber 29, whence filtrate passes out at 24. In Fig. 3 (not shown), the cylinder 28 is replaced by a plurality of layers of wire cloth which are under compression.

Title: Improvements relating to drum brake mechanisms particularly for vehicles
IPC: F16D53/00
Filed: 1957-06-12
Abstract: 822,662. Drum brakes. DELOREAN, J. Z. June 12, 1957 [June 14, 1956], No. 18566/57. Class 103 (1). A combined expanding and contracting shoe drum brake comprises a drum having a web member 22 contoured to receive a liner 28 providing radially spaced concentric braking surfaces 30 and 32. Inner and outer brake shoes 48 and 50 are applied to the surface 30 and 32 by an hydraulic cylinder and piston 76, 78. Since the inner shoe 48 is held against rotation by a pin 60 passed through a hole 58 in one end thereof, the drum rotation, as indicated by the arrow 86, tends to move the outer shoe 50 relative thereto so that the interaction of the rollers 72 on the ramps 68 and 70 tends to spread the shoes apart against the drum surfaces. Automatic adjustment of the shoe clearance may be carried out by a piston 92 having a non-return valve 98 therein in the hydraulic line to the cylinder 76. In another embodiment shown in Fig. 7, the hydraulic actuator cylinder 329 is disposed circumferentially between the adjacent ends of the friction members 321 and 323 which are of band form. The hydraulic actuators 459 may be disposed outside the drum as shown in Fig. 11, and operate against the ends of the shoes, by means of levers 455 and 461 pivoting on a floating link 465. The web member 22 of the drum is preferably provided with a plurality of cooling fins 534, as shown in Fig. 13.

Abstract: 1,008,615. Valves. W. FREDE. May 5, 1964 [May 17, 1963], No. 18662/64. Heading F2V. [Also in Divisions G2 and G3] A pressure transmitter comprises a first housing 1 provided with a diaphragm 2 connected to a threaded spindle 3 which engages, at its other end, a differential diaphragm mounted in a second housing 7, and composed of diaphragms 8a separated at their outer periphery by discs 8 and at their inner periphery by washers 8c. Each of said discs has a radial passage 14 connecting each of the chambers between the diaphragms with an axial passage 11 which communicates with an inlet for a pressure fluid via a constriction 13 and with an outlet 12a. The end of the spindle is provided with a hollow casing 9 which is formed with two valve seats coacting selectively with a member 10a to control the escape of fluid from chamber 17. The passage 11 is provided with a piston-like valve member 15 to selectively control admission to the chambers, the member comprising a rod 15c having an enlarged end 15d between which and a cylinder 15b is arranged a deformable seal-ring 15e. A spring 6 is provided the effective length of which may be varied by screwing it on to a nut 5 which in turn threadingly engages the spindle. In operation, the transmitter is balanced when the spring force and the force on the differential diaphragm equal the force on the diaphragm 2, the seating 9a coacting with the member 10a. Any subsequent change in the pressure in housing 1 is transmitted via the outlet 12a. In a modification, the spring may seat against the first housing and thus act in the opposite direction, and to increase the range of the transmitter two differential diaphragms may be used in series, each having a selector valve. If it is required that increases in the pressure in the first chamber be transmitted as decreases in control pressure, the differential diaphragm may be reversed or the member 10a may be arranged to coact with seating 9b.
