Patent GB-962407-A (GB)
Title: Improvements in or relating to automatically single-acting slack adjusters for vehicles
IPC: F16D7/02
Filed: 1962-07-13
Abstract: 962,407. Brake slack adjusters. SVENSKA AKTIEBOLAGET BROMSREGULATOR. July 13, 1962 [July 20, 1961], No. 27050/62. Heading F2E. An automatic slack adjuster incorporated in a pull rod of vehicle brake rigging is of the singleacting type comprising a tubular rod part, a threaded rod part, and a nut pressed into frictional engagement with an abutment associated with the tubular rod part by a spring, characterized in that a rotatable sleeve is provided in association with the tubular part having one abutment surface in contact with the nut and another abutment surface in contact with an abutment surface of the tubular part, the two pairs of abutment surfaces forming friction clutches normally preventing rotation of the sleeve which, however, can be rotated manually to effect manual adjustment. In one embodiment, Fig. 1, the sleeve 7 is journalled within an enlarged end part 11 of the tubular rod part 1 and provided with abutments 5, 8 engaging abutment surfaces 4, 9 on the nut 3 and part 11 respectively. A spring 6 acts on nut 3 via ball race 10 to urge it in a direction to engage both pairs of abutment surfaces which normally lock the nut against rotation around threaded rod part 2 with which it is in non self-locking relationship. When excessive wear has ocurred the parts 1, 2 are pushed towards each other during brake release to free the nut 3 from abutment 5 allowing spring 6 to rotate it in the slack reducing direction. When new brake linings are fitted slack can be paid out manually by rotating an extension 12 of the sleeve 7 by hand or with a hand tool, thus avoiding dismantling. Fig. 4 shows the preferred arrangement including a power actuator 18 acting via link 17 and lever 20 on brake shoe 16, and a hand brake lever 15 connected by the adjuster parts 1, 2 to and a lost-motion connection 23, 24 to a lever 22 coupled by link 21 to the lever 20, the extent of lost-motion determining the normal amount of slack. In a second embodiment, Fig. 2, nut 3 is self-locking and composed of segments held together by an encircling spring 3a. Automatic adjustment is therefore by ratchet action whilst manual adjustment can be effected by rotation of the nut as before. In a third embodiment, Fig. 3, part 11 is omitted and sleeve 7 is modified to provide the housing for the nut, the pairs of abutment surfaces 4, 5 and 8, 9 performing the same function as those of the first embodiment and the operation also being identical to that of the first embodiment.

Title: Anti-friction bearings and associated members
IPC: F16C35/077
Filed: 1947-10-08
Abstract: 636,071. Circlips. BENDIX AVIATION CORPORATION. Oct. 8, 1947, No. 27060. Convention date, Oct. 25, 1946. [Class 89 (ii)] [Also in Groups XXII and XXXIV] Anti-friction bearings are secured against axial movement by a spring ring fitted to complemental grooves completely closed axially but radially open to one another in the race rings and the members on which they are mounted. As shown, an outwardly sprung split ring 118 secures to a member 68 the outer race of a ball-bearing 66, the groove in the latter being twice the radial width of the groove in the member 68 to permit compression of the spring during assembly. In this application the ring has one face bevelled whereby an axial force in one direction greater than the normal thrust load will permit dis-assembly. In modifications the ring may have both faces bevelled or may comprise a garter spring. In further modifications a destructible parallel sided ring is fitted between the outer race ring and adjacent member or between the inner race ring and the shaft, or both, and may be normally sprung outwards or inwards, the grooves being cut to an appropriate depth. An application of the invention to the loose pinions of an aircraft engine starter epicyclic gearing is shown, in which case the bearings are also force fitted.

Title: Improvements in the manufacture and production of carbon-containing fertilisers
IPC: C05F11/02
Filed: 1932-09-30
Abstract: In a process for the production of solid carbon-containing fertilizers, active carbon may be obtained by heating carbonaceous substances such as wood e.g. sawdust, wood charcoal, peat, peat charcoal, brown coal or brown coal coke in the presence of activating agents which themselves preferably have fertilizing action or constitute components of fertilizing salts, as for example caustic potash, potassium carbonate or phosphoric acid. The active carbon may also be obtained by causing anhydrous oxides of phosphorus, preferably phosphorus pentoxide, to act on uncarbonised carbonaceous substances of vegetable origin without any substantial supply of external heat, e.g. in a rotary tube--if necessary the reaction may be started by the addition of a very small quantity of water or by a limited local supply of heat; carbonaceous substances specified are wood e.g. beechwood chips, cellulose, lignin, sugars e.g. dextrose, starch e.g. potato starch, and peat.ALSO:A process for the production of solid carbon-containing fertilizers consists in neutralizing the unwashed intermediate products having a strong acid or alkaline reaction obtained in the preparation of active carbon by carbonizing carbonaceous substances with such solid or dissolved activating agents as leave after the reaction no constituents injurious to plants, and retaining in the product all the salts formed by the neutralization.  Other fertilizing substances such as urea or ammonium salts may be added during or after the neutralization. The active carbon may be obtained by heating carbonaceous substances such as wood, e.g. sawdust, wood charcoal, peat, peat charcoal, brown coal or brown coal coke in the presence of the activating agents.  The activating agents themselves preferably have fertilizing action or constitute components of fertilizing salts, as for example caustic potash, potassium carbonate or phosphoric acid.  The active carbon may also be obtained by causing anhydrous oxides of phosphorus, preferably phosphorus pentoxide, to act on uncarbonized carbonaceous substances of vegetable origin without any substantial supply of external heat, e.g. in a rotary tube-if necessary the reaction may be started by the addition of a very small quantity of water or by a limited local supply of heat; carbonaceous substances specified are wood, e.g. beechwood chips, cellulose, lignin, sugars, e.g. dextrose, starch e.g. potato starch, and peat.  Neutralizing agents specified are the oxides, hydroxides and carbonates of the alkali and alkaline earth metals e.g. potassium carbonate, ammonia e.g. as a gas or as an aqueous solution containing potassium nitrate and ammonium nitrate, phosphoric or nitric acids or mixtures of these acids.

Abstract: 1,081,064. Testing and clearing yarns; stop motions. W. REINERS. July 3, 1964 [July 4, 1963], No. 27527/64. Headings DID, D1F and D1J. The presence or absence of a running thread in a textile machine is detected and/or the roughness of the thread is measured, in terms of variation in thickness of the thread core and/or fibres protruding therefrom, by a device wherein the thread F is passed between a light source or lamp 1 and a photo-electric cell 2. A diaphragm 3 having an elongated slot 4 of width not greater than three times the thickness of individual thread fibres f, or an optical system (not shown) for producing a correspondingly narrow beam of light impinging on the cell 2, is positioned on one side or the other of the thread F. Each protruding fibre or variation in thread thickness is reflected in the output current circuit 2a of the cell by an electric pulse or pulse fluctuation, the pulse signals are separated by a highpass filter, Fig. 2 (not shown) amplified, and perhaps smoothed by means of an integrating member, Fig. 4 (not shown) to provide effective direct measurements. The absence of a fibre frequency or unacceptable amplitude thereof may initiate operation of a stop-motion. Thread entanglements and/or faulty sections may be severed automatically by a magnetically operated cutter the current circuit of which is adapted to be interrupted by a micro-switch actuated by the detecting device.

Abstract: 1,181,273. Liquid filter. G. MAESTRELLI. 15 June, 1967 [15 Feb., 1967], No. 27618/67. Heading B1D. [Also in Divisions D1 and D2] A filter used in the solvent circuit of a coin-freed dry-cleaning machine comprises a plurality of filter elements D, made of wire wound on flat frames of moulded plastics, having lozenge-shaped cross-sections and being radially arranged about and supported by two or three rotatable hollow shafts F. After a washing cycle, during which solvent passes continually through the filter and back to the washing tub, the solvent flow is stopped and the shafts are rotated or arcuately reciprocated by a common motor (64), creating turbulence in the dirty solvent around the elements and thereby washing the used, absorbent, filter aid and solids therefrom. Periodically a sludge outlet (72) in the housing floor is opened. In Fig. 2 and Fig. 3 (not shown) the elements D intermesh and turbulence is concentrated in zone H. In Fig. 4 (not shown) the elements of the different assemblies do not intermesh and there is less turbulence. Within the limits of the filter housing, additional filter elements may be added to each ring of elements, and further complete rings of elements may be mounted axially above the first on each rotatable assembly. The ends of elements open into hollow radial arms of plastics spiders between which elements are clamped, the spiders (G) open into the interiors of shafts F and these discharge filtrate by outlets (70). Sludge discharged by outlet (72) passes to a distillation plant which recovers the filter aid.

Abstract: 1339837 Harmonic generation SPERRY RAND CORP 14 June 1971 [16 June 1970] 27714/71 Heading H2F [Also in Division H3]  A microwave or high frequency converter comprises a hollow transmission line 1 with a septum 5 extending from a conductor 4 between conductors 2 and 3, an end wall 8 conductively fixed to the conductors 2, 3 and having a coaxial transmission line 22 coupled through the wall 8 to the septum 5, a further end wall 9 insulated from the conductors 2, 3, semi-conductor means 10 connected in series with the septum 5 and the further end wall 9 and impedance matching means 30, 31, 32 positioned between the conductors 2, 3. In use the bias voltage applied at 16 across the semi-conductor means 10 is adjusted near the critical breakdown electric field of the means 10 and a high frequency signal WF applied via the coaxial transmission line 22 of sufficient amplitude causes this critical field to be exceeded so that the diode generates an avalanche shock wave producing fundamental and harmonic signals across the semi-conductor means 10. The circuit can operate as a signal converter, self excited oscillator or amplifier and frequency multiplier. For operation as an amplifier the input signal is applied via one part of a circulator to the line 22 and an output is taken from another part of the circulator. The fundamental or harmonic output is selected by adjusting tuning or susceptance matching or transforming elements 30, 31, 32. These may be conductive U-shaped elements 30, 31, 32 and the longitudinal position of each may be secured by a bolt 35 which slides in a slot 33 in the conductor 3. These matching elements may alternatively be formed by a dielectric tuning or matching slab (40, Fig. 5, not shown) which contacts the side conductors 2, 3, 4 and the septum 5. The tuning elements 30, 31, 32 may after optimum adjustment be permanently fixed in position. A dielectric strip 14 insulates the end 9 from the side conductors 2, 3, 4 and provides a h.f. shorting means. The semiconductor diode may be an IMPATT or TRAPATT avalanche diode or other PN or abrupt junction diode or a PNN<SP>+</SP> punch through diode.
