Abstract: 1470990 Packaging in aseptic conditions ZIRISTOR AB 8 Aug 1974 [24 Aug 1973] 34996/74 Heading B8C In an apparatus for packaging under aseptic conditions comprising a conveyer belt 2 which is adapted to hold containers 1<SP>1</SP>, 1 to be filled and which co-operates with a tunnel 4 to define a sterile space 5 in which are arranged container filling and closing devices 12, 13, a device 11 for spraying high energy electrons to sterilize the containers is provided within the space 5 or at the location whereat the containers enter said space. The conveyer belt may include openings 3 or recesses for holding the containers. The edges of the openings are bevelled to match the taper of the containers which are frusto-conical in shape. Downwardly and inwardly inclined portions (32), Fig. 2 (not shown), of the longitudinal side walls of the tunnel 4 seal with downfolded longitudinal edges (34), Fig. 2 (not shown), of the conveyer belt 2 or with longitudinal sealing members (33), Fig. 2 (not shown), on the conveyer belt. The containers are closed by heat-sealing a web 15 to the containers. The web 15 is introduced into the space 5 after passing through a vat 17 of sterilizing and/or washing liquid and past an air doctor blade device 19, liquid absorption and heating devices 20, 21, an ultra-violet irradiation device 25 and an electron spraying device 26. The entrances and exits to the space 5 are protected by devices 8, 9, 23 and 24 which prevent the surrounding atmosphere entering the chamber. Such devices may include an electron spraying device, a sterile air curtain, a liquid curtain made up of finely divided hydrogen peroxide or alcohol particles or a sealing member. The pressure in the chamber may be maintained at a value above atmospheric pressure. The closure web 15 is severed between individual containers by a knife 28 which also produces a tab 29 in the closure.

Abstract: 522,178. Drum brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and GATES, G. R. G. Dec. 2, 1938, No. 35229. [Class 103 (i)] In internal shoe drum brakes of the kind in which the shoes are pivotally supported each on an actuating lever, the shoes are adjustable relatively to the lever to compensate for wear. A pair of levers, of which one 19 is shown, each carrying a shoe 31, have curved end surfaces 21, 22 which normally abut on corresponding fixed surfaces of applying devices 12, 13 comprising each a pair of plungers 55, 56 which may be hydraulic pistons or a device according to Specification 495,834, Both shoes thus act in a leading sense with either direction of drum rotation Each shoe has a pair of webs 35, 36 disposed between the webs 38, 39 of the corresponding lever and a pin 40 passes through holes in the shoe webs and through radial slots in the lever webs to permit pivotal and radial movement of the shoes relatively to the levers. Adjustment is effected by a screw 42 with an operating head 52 and which screws into the lever and engages the pin 40. Lateral displacement of the levers is prevented by projections 28, 29 of the casing of the operating devices. In a modification, the shoes are of T- section and the adjusting screw engages part of the web. The two applying devices may be mounted on a support of cruciform shape, the lateral arms of which provide bearing surfaces for the middle parts of the levers.

Filed: 1959-10-20
Abstract: 900,747. Portable drilling machines. SUNBEAM CORPORATION. Oct. 20, 1959 [Feb. 13, 1959], No. 35536/59. Class 83 (3). A portable electric-drill comprises a motorhousing 10 having a pistol-grip 15 fixed thereto, a handle 16 detachably secured to the housing substantially in line with the grip 15, and a rear-handle 14, detachably secured at 24. The handle 14 has bosses 14c which are resiliently urged towards each other, and engage with recesses 21 in the housing 10, thus locking the handle against rotation in an anticlockwise direction relative to the housing as seen in Fig. 1, by keys 14d, which engage keyways 22 in the recesses 21, and by the edges 21a-21c, Fig. 4, of the recesses 21. Screws 23 prevent accidental removal of the handle 14. To remove the handle 14, the screws 23 are removed, the handle is pivoted clockwise relative to the housing 10 and, due to the tapers on the edge 21b of the recesses 21, on the keys 14d and on keyways 22, the bosses 14c are moved apart, and the keys 14d are released from the housing, thus allowing removal of the bosses from the recesses. Ribs 31 support the motor stator and also reinforce the housing adjacent the recesses 21.

Abstract: 1,059,227. Adjusting radio tuning. OAK MANUFACTURING CO., DIVISION OF OAK ELECTRO/NETICS CORPORATION. Sept. 4, 1964 [Sept. 5, 1963], No. 36444/64. Heading H3Q. In a television channel selector fine tuning means are provided for each channel, actuable by rotatable means located at a fixed point and which rotate with the channel selecting means. Channel selector shaft 14 is journalled in walls 11, 12 and is arranged so that it may be rotated step by step by means of spring 16 and index plate 15, each step corresponding to the setting for one of the channels. The fine tuning mechanism includes a rotor support 25 mounted on channel selector shaft 14, to which is secured a rotor 29 carrying fine tuning components, e.g. inductors and capacitors, one for each channel. Tuning is performed by means of screws 30 threadably mounted in a flange 26 on rotor support 25, each screw 30 being provided with a gear head 31, the operative one of which meshes with a gear 54. Gear 54 is mounted on a shaft journalled in bush 53, which is inserted in wall 11, and which carries a further gear 51: this meshes permanently with gear 44 which is carried by a sleeve 40 capable of rotation about the shaft 14 by means of a knob (not shown). Gear member 44 further includes an axially extending split sleeve portion 46 which is surrounded by a spring member 50, whereby it is frictionally coupled to the shaft 14, so that rotation of this shaft also causes rotation of the gear 44: the pitch circle of each of the gear heads 31 about shaft 14 is made tangential to the corresponding pitch circle of gear 44, so that rotation of the latter with shaft 14 does not disturb the settings of gear heads 31 when engagement of each of these is effected. Reference has been directed by the Comptroller to Specification 913,382.
