Title: Improvements in and relating to hydraulic axial ram pumps and motors
IPC: F01B3/00
Filed: 1962-05-02
Abstract: 977,288. Reciprocating motors and pumps. H. THOMA. April 29, 1963 [May 2, 1962], No. 16856/62. Addition to 895,805. Heading F1A. In an axial piston motor or pump, the revolving cylinder block is supported against tilting either by bearings 29, 30 surrounding the block, as shown, or by a bearing surrounding the block and another bearing on a drive shaft secured to the block. A valve plate 14 is located against rotation by sleeves 16 which may be resilient or have sufficient clearance to permit self-alignment of the valve plate with the cylinder block. The valve plate is biased against the block by spring-loaded balancing pistons communicating with the valve ports and outing between the casing and the valve plate. The timing may be adjusted by angularly adjusting valve plate 14 relative to the block, either by hand or automatically, sleeves 16 then being carried wholly by the block or the valve plate. The bearing surfaces of the block and valve plate are pressure lubricated. Swash-plate inclination may be fixed or adjustable by rotation of a shaft 7.

Patent GB-497430-A (GB)
Title: Improvements in or relating to direct current electric motor control systems
IPC: B60L15/12
Filed: 1937-06-21
Abstract: 497,430. Master control of D.C. motors. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. June 21, 1937, No. 17224. [Class 38 (iii)] Field control ; dynamoelectric braking.- Forward movement of a controller 9 from position VI is effective to reduce the excitation of the shunt field 3 of a compound-wound motor 1, but return movement is ineffective to restore the shunt excitation to its full value, until the controller has been moved backwardly beyond the position VI, and then full shunt Held is restored only if no regeneration or a limited amount of regeneration takes place. On the first step of the controller 9 the motor 1 is connected to the supply with full armature resistance in circuit and only its series winding 2 energized. On the second step the shunt field is fully excited by closure of contactors 15, 15W, 16, 16W, 17, 17W, and on subsequent steps the armature resistance is gradually cut out by energization of contactors 22, 22W, 23, 23W, 24, 24W. The shunt field is then reduced in two steps by de-energization of contactors 17, 16, and then disconnected by de-energization of the contactor 15. Finally the series field is weakened by energization of a contactor 25, 25W. When the contactor 17 is opened at position VII, to reduce the shunt field, it opens interlock contacts 17NO in its own circuit, so that it can be reclosed only by returning the controller to its first position I. If the controller is operated to its off position when the motor is running at an appreciable speed, regeneration occurs if the motor is reconnected to the supply with full shunt field, and if an overvoltage results a relay 67 operates to disconnect the motor. In addition to its own interlock contacts 17NO, the maintaining circuit of the contactor 17 includes normally open interlock contacts LPNO2 on the line switch LP. Relay contacts 65 operated by a coil 27 in series with the motor, and also in some cases by a coil 28 connected across the motor armature may be arranged to prevent energization of the contactor 17 to give full shunt field if the conditions are such that regeneration would result. A controller 10 for rheostatic braking is interlocked with the controller 9 to render the latter effective when the braking controller is operated, and motoring is possible only when both controllers have been restored to their off positions.

Title: Assembling carriers with containers
IPC: B65D85/20
Filed: 1966-04-20
Abstract: 1,145,672. Packaging machines; endless conveyers. ILLINOIS TOOL WORKS Inc. 20 April, 1966 [19 May, 1965], No. 17299/66. Headings B8A and B8C. Apparatus for applying elastic carriers to groups of cans &c., the carriers having can receiving apertures of lesser diameter than the upper ends of the cans, comprises means to position a marginal portion of each aperture below the level of the can upper ends while the remainder is above this level and means to stretch the remainder round the cans to embrace the upper ends. The stretching means described are pairs of pins which, while within the apertures, follow the circumference of the can ends on opposite sides. Cans 12 are fed by belts 74 to a slower running conveyer 78, the flights 98 of which form pairs of pockets extending transversely. A carrier web 24, weakened at package length intervals, is fed by drive rollers to a guide 66 overlying a conveyer carrying the applying means. In one embodiment, Figs. 4, 10, these consist of a pair of pins 120 for each can, carried by a four arm linkage 142, 144, 128, 130, opposed pivot pins 136, 146 of transverse pairs of linkages sliding in slots 124, 126 in a bar 116. The bars 116 are carried by conveyer chains 110. A depresser element 122 (see also Fig. 11B) is mounted on each bar between the linkages. Discs 156 secured on the pivot pins 146 prevent undesired engagement between the links and carriers. The pins 136 and 146 have followers 138, 148 running in cam tracks, Figs. 9A, 9B (not shown), surrounding the path of the chains 110, the pins being thus constrained to follow the can circumferences on opposite sides. As the carrier leaves the guide 66, it is forced into a V-groove in a stationary bar 172 by the depressors 122. The bar 172 follows the web path to where it overlies the cans and thus the carrier centre is depressed between the two rows of cans, Fig. 11B. The pins 120, which entered the apertures when the web was applied to the bars 116, now move from adjacent the depressors to the opposite sides of the cans to pull and stretch the aperture margins over the can ends. In another embodiment, Fig. 15, pins 216 on pairs of spring arms 212 function in a similar manner to the pins 120 but circumscribe the cans by contacting and running along their rims. Their transverse movement may be derived from a converging-diverging chain arrangement, the chains 210 having lateral flexibility, or by cam means (not shown) similar to that of the first embodiment. The assembled packages slide on to a bar 106 and the separating effect of the flights 98 as they move angularly to withdraw from between the cans, may be relied upon to break the carrier web at lines of weakness such as 30, 32, 34, Fig. 12. If the carriers include handles 44, held temporarily by web portions 50, rotating knife means (not shown) may free them by severing these portions from below while the packages are on the bar 106. Reference has been directed by the Comptroller to Specifications 998,736, 974,619 and 922,591.

Title: Improvements in or relating to synthetic rubber adhesives
IPC: C08L21/00
Filed: 1957-06-03
Abstract: 863,308. Synthetic rubber adhesives; metal oxide-phenol-aldehyde reaction products. B.B. CHEMICAL CO. Ltd. June 3, 1957 [June 11, 1956], No. 17503/57. Classes 2(5) and 2(6). An adhesive composition comprises an organic solvent solution of a synthetic diene polymer rubber and a substantially infusible reaction product of PbO, MgO or ZnO and a thermosetting, oil-soluble, alkali-catalyzed condensate of an aldehyde and a monosubstituted phenol of which the substituent contains at least 3 C atoms, in which there is more than 1 mol. of aldehyde per mol. of the phenol, wherein the reaction product has been freed from uncoagulated solvent insoluble components before formation of the solution. The adhesives are made simply by mixing a solution of the rubber in a volatile organic solvent with a solution of the metal oxide-resin reaction product. Examples disclose adhesives composed of polychloroprene, MgO, antioxidant, a solvent mixture of ethyl acetate, toluene and naphtha and the reaction product of (1, 8) MgO and p-tertiary butyl phenol-formaldehyde condensate, (6) PbO and p-phenylphenol-formaldehyde condensate and (7) MgO and p-phenylphenol-formaldehyde condensate. The infusible metal oxide-resin reaction products are made by dispersing the finely divided oxide in a solution in a volatile aromatic hydrocarbon solvent of the alkali-catalysed phenolaldehyde resin, whereupon an exothermic reaction ensues at room temperature. The insoluble matter is then removed, e.g. by drying and re-dissolving the reaction product or by filtering. Phenols specified are p-tert. amyl-, p-tert. butyl- and p-phenyl-phenols. The preferred reaction products contain by weight 25-30% of Pb calculated as PbO, 7À5-9% of Mg calculated as MgO and 9% of Zn calculated as ZnO. In Examples (1, 4) freshly prepared, finely ground MgO was added to a solution of a NaOH-catalysed condensate of p-tert. butylphenol and formaldehyde in a mixture of toluene, ethylacetate and naphtha, and allowed to react with the resin; a clear liquid was separated from insoluble matter and freed from solvent to yield a dry, brittle product; (2) PbO, (3, 7) MgO and (5) ZnO were similarly reacted with p-phenyl phenol-formaldehyde resin.
