Title: Improvements in and relating to soaking tanks for the initial cleansing of bottles, jars and the like
IPC: B08B9/26
Filed: 1923-11-03
Abstract: 227,949. Powley & Sons, Ltd., R., and Powley, M. Nov. 3, 1923. Bottles, washing.-A soaking machine of the intermittently-rotated pocket-wheel type in which the bottles &c. are automatically introduced and discharged comprises a tank 1 partly filled with liquid in which rotates a wheel 3 having inclined pockets 4 arranged in rows of eight pockets. The bottles 5 are placed in four cradles 11 fixed to a rock-shaft 12 mounted near a feed aperture 6 when these cradles are in the horizontal position shown dotted in Fig. 1. The cradles 11 are spaced so as to register with alternate pockets 4 and are tilted by levers 15 connected by arms 13 with a shutter 16 controlling the feed aperture and moved vertically by cranks 8 through connecting rods 10. A series of holes 8<a> in the cranks 8 enables the timing of the shutter to be adjusted, and this is so arranged that the cradles are fully tilted before the shutter releases the bottles, so that they slide into the pockets and are carried upwards through the heated vapour, thus being warmed before immersion in the hot liquid. The shaft 12 carrying the cradles 11 is then moved laterally by a lever 17 pivoted at 17<a>, having forked ends, one end engaging a pin 20 on the shaft 12 and the other a crank 18 driven by a shaft 19, so that the cradles are positioned opposite another set of pockets. The discharge aperture 7 is controlled by two shutter members one of which, 21, prevents all the bottles in a row from discharging while the other, comprising four shutters 24, allows bottles to pass from alternate pockets on to four cradles 30. Vertical reciprocating movement is imparted to the shutter 21 by cranks 22 and connecting rods 24, in a similar manner to the shutter 16 and the shutters 24 are fixed to a horizontal shaft 25 reciprocated axially by a forked lever 27 rocked by a crank 28 on the shaft 19, in a similar manner to the shaft 12. The timing is so arranged that the bottles make 3¢ revolutions before being discharged. The cradles 30 are pivoted at 31a to a fixed rod 31 and have pin-and-slot connection with the shaft 25 so that they rock laterally to register with the pockets to be emptied. Intermittent drive is imparted to the pocket wheel 3 through a radially-slotted wheel 4 in the slots 40<a> of which works a roller 41<a> on a crank 41 driven by chain gearing from the driving shaft 36, which also drives through a chain 38 the cranks 8, 22. The wheel 3 is locked during the charging and discharging operations by a spring- pressed bell-crank lever 45 having a roller 46 which is released by a cam 56 to take into one of a number of slots 47 in the wheel 40 each time the roller 41<a> leaves a slot 40a. Blades 52 on the pockets 4 cause a flow of liquid towards the open end 51a of a perforated basket 51 thus sweeping labels &c. into the basket, which can be removed through doors 54.

Abstract: 1,068,916. Photo-copying apparatus. GRAFEX CORPORATION. July 2, 1965, No.28127/65. Heading G2A. The photo-copying apparatus 20, shown in operative position in Fig. 3, can be collapsed into the folded-up form of Fig. 2 (not shown) for convenient transportation. It comprises side walls 21, 22 hinged at the top to a channelsection support 27 and joined together at each end by bellows-like wall portions 28. A transparent pressure plate 42 is hinged at one end 43 to side wall 21, and can be held at the other end by a spring detent 46. Below plate 42 is a support panel 51, also hinged to side wall 21, but so arranged that it can be detached therefrom if required, e.g. for copying a page of a book. (In the collapsed position, both panel 51 and plate 42 can be swung up so as to lie between side walls 21, 22.) The upper face of panel 51 has a cushion 54 of resilient material. Thus photographic sheets placed in contact between cushion 54 and plate 42 are held firmly and flat. A series of flash bulbs 107 are supported in an elongated strip 101, Figs. 6 and 7 (not shown), each bulb passing through an opening (104). The strips are so shaped at their ends (105, 105a) that each strip can lock into the preceding one to form one continuous strip. One edge (102) of the strips is straight, but the other edge is serrated, having the form of a series of ratchet teeth (103). The strips slide in grooves 64, 65, Figs.2 and 11 (not shown) in support 27, so that the bulbs depend therefrom to provide the illumination in the 'open' position of Fig. 3. The strips are moved along in a series of steps by a spring- loaded pawl 83, Fig. 13 (not shown) having a bentdown end (84) which engages one of the teeth (103). The pawl can be actuated by a strip 92 Fig. 1 (not shown) whose end (90) extents through a slot (91) to the exterior of the apparatus. As each bulb in turn reaches the exposure position, it passes between spring contacts 73, 74, 77, Figs.9 and 10 (not shown), so completing a circuit causing it to fire. Thus the whole sequence of flash bulbs can be moved along into the exposure station and fired, one after the other, merely by pulling the end (90) of the strip (92).

Abstract: 1,039,043. Batteries. SVENSKA ACKUMULATOR A.B. JUNGNER. July 18, 1963 [July 20, 1962], No. 28410/63. Heading H1B. In a hermetically sealed cell having a sealing grommet 4 interposed between the lid 3 and container 1, the lid and grommet are retained by a rim 5 of the container and the cell is designed to permit gas to leak between the rim 5 and the grommet. This leakage may be achieved by providing scores 7 in that part of the grommet in contact with the rim (Fig. 5), by providing corrugations 6 in the rim 5 (Fig. 2) or by interposing a corrugated disc between the rim and grommet (Fig. 4, not shown). The lid shown in Fig. 5 is dished to permit expansion of the cell on rise in pressure. As the pressure increases the lid flattens, improving the radial seal between the grommet and container, and then bows outwardly allowing gas to escape through the passages 7 between the rim and grommet. If the lid is a snap-action retractive disc the container is made correspondingly resilient, but if it is not a retractive disc the container is arranged to deform beyond its elastic limit.
