Abstract: 1,261,347. Workbenches; gripping tools. PILKINGTON BROS. Ltd., B. F. TICKLE, L. STRETCH, and W. E. BUTLER. 17 March, 1969 [28 March, 1968], No. 15015/68. Headings B4W and B4X. [Also in Division E2] An insulator element (Fig. 1) is assembled by a method comprising inverting the insulating body 1 with the axis of its central cavity 4 vertical, depositing a predetermined quantity of cement 6 in the cavity, centring pin locating means (Fig. 2) on the body by engagement thereof with a surface of the skirt 3 of the element so that a bore 18 in the locating means is aligned coaxially with the axis of the cavity 4, a pin connector 5 being releasably held in the hole 18, urging the pin 5 axially relative to the locating means into the cement in the cavity and releasing the pin from the locating means when the cement has hardened. In one embodiment (as shown), the pin 5 is releasably held in the frusto-conical bore 18 surrounded by skirt 3, by a split collar 22. In a second embodiment (Fig. 9, not shown), the split collar is received in a tube (54) which is a sliding fit inside inner and outer members (55, 57 respectively). In a third embodiment (Fig. 10, not shown) the collar is slidably received in inner and outer members. In a fourth embodiment (Fig. 6, not shown) for use with short pins 5, the split collar 22 is formed with a depression (23<SP>1</SP>) concentric with the bore, for receiving part of the enlarged head of a pin. In each embodiment the part or parts receiving the split collar have means for engaging a rib or ribs on the underside of the skirt 3 of the insulator element to centre the pin locating means on the element. Such centring means may comprise abutments which merely rest on or about one or more ribs, or may comprise an annular channel 21 (Fig. 2) concentric with the bore 18. In automatic assembly of the insulator elements (Fig. 4, not shown), the inverted elements mounted on pallets (31) are fed by roller conveyer (32) to a jig (36). Prior to this a cork spacer disc is placed in the base of the cavity 4 and a charge of cement is added. With the pallet in position in the jig, the former is raised by a ram (40) until the insulator element is abutted by thrust pads (48), when a further ram (41) moves downwardly to cause a thrust ring (43) to engage the upper surface of the skirt 3 and a piston (42) to engage pin head 9 to press the pin 5 into the cavity 4. The entire jig (36) is vibrated during such pressing. When the pin end 7 abuts the cork spacer the rims retract and the pallet is removed on the conveyer. When the cement has hardened, the pin locating means are removed using a release tool (Fig. 7, not shown). Conductive caps 12 may be fitted to the bosses 2 of the assembled elements.

A carriage 10 has mounted thereon slip-casting moulds 12a, 12b etc. into which cores 13a, 13b &c. are fitted by vertical reciprocation of a beam 59, the connections 65, 68 between the cores and the beam being movable relative to the beam and the lengths of the rods 68 being the same for pairs of cores equidistant from the hoist point 75, but different for each pair of cores. As shown, the rods 68 are longest for the core pair 13e, 13f so that as the beam is raised cores 13a, 13b, then cores 13c, 13d and finally cores 13e, 13f are raised from the moulds. An odd number of moulds may be utilized by having one mould directly below the hoist point and the provision of more than one hoist point is also mentioned. The moulds are mounted on a carriage 42, Fig. 4 (not shown), so that they may be moved laterally as a unit from beneath the cores 13. The cores are locked in the moulding position by means of an angled arm 91, 93, Fig. 6 (not shown), which carries an eccentric 89 bearing on beam 59 in the locking position. Pressure is applied to each core by the beam to satisfactorily displace the slip, but to prevent strain and to equalize the pressures a keel bar 109 is provided which acts on a spring-loaded bar 94 provided for each core. A plant is described, Fig. 1 (not shown), comprising a rectangular array of rails 11, prime movers 14, 19, 21 and 24 and stations A to H where the following operations take place: at A-cores and moulds interfitted, at B-slip added, at C-cores extracted and dusted, at D-moulds offset with respect to cores and the latter dusted (if this was not done at C), at E-drying of the slip, at E- castings removed, at G-green castings smoothed and stacked, and at H-moisture removed from cores and moulds.

Abstract: 1,219,473. Optical store. WESTERN ELECTRIC CO. Inc. 29 March, 1968 [31 March, 1967], No. 15119/68. Heading G4C. Optical store comprises material exhibiting a persistent change in its refractive index, causing rotation of a polarization vector, after exposure to electromagnetic wavelength of a first wavelength and intensity; means for directing at the material radiation of the first wavelength and intensity when a " 1 " is to be stored; and interrogation means directing at the material polarized radiation of a second wavelength and intensity ineffective to produce the change, and means responsive to the subsequent direction of the polarization vector of the polarized radiation for detecting the presence or absence of the change. Light from a laser 13 passes through a light deflector 11 to a sheet of material such as single crystal lithium niobate 14. An argon laser (#=À488 ) at 150 milliwatts is sufficient to cause the change in refractive index. Light from a helium-neon laser (#=À633 ) at 1 milliwatt does not affect the material and is used for read-out. During read-out the material is preferably between crossed polarizers to suppress radiation passing through portions storing " 0 " and thus having a polarization vector unchanged, but passing a portion of the light indicating " 1's." The store can be erased as a whole by heating or individual bits can be erased by light from a mercury lamp.

Title: Improvements in or relating to record card sorting machines
IPC: F22B1/30
Filed: 1952-06-18
Abstract: 710,226. Statistical apparatus. MAUL, M. June 18, 1952 [July 3, 1951], No. 15308/52. Class 106 (1) In a statistical record card sorting machine for handling multi-deck record cards, the analysing device is movable transversely of the card to position it over a selected column and is provided with manually operable driving means for moving it and for deck selection means for rendering the analysing device selectively operative on any one of the decks of a card. The apparatus is further characterized in that means are provided to reverse the direction of movement of the analysing device in continued unidirectional movement of the driving means after the analysing device has reached the end of a deck and means automatically operated concomitantly with the reversal to actuate the 'deck selection means to render the analysing device operative in a different deck of the card. Analysis of the columns is effected by brushes 25, Fig. 2, set to the desired column by screw spindle 26. The brushes are raised during movement by cams 41 on to shaft 35 which also serves as a guide. The shaft 35 is driven through gears 37, 38, 39 from the screw spindle 26 which rotates once for each column displacement. The shaft 35 is mounted on the two arms 36 which may be rocked about the spindle 26. The cam discs 41 are urged against stops 43 by springs 42. On column adjustment the cams 41 rotate lifting the arms 36 and the brushes 25. Deck selection is effected by the cam disc 11, Fig. 1, which is driven through worm gear 12 and worm 13, the worm 13 is fast on the shaft 14 upon which crank 15 is secured. The cam 11 is fast together with worm wheel 12. The position and shape of the cam disc 11 are such that the movement of lever 21 by means of a nose 22 occurs at the moment when the column indicating pointer is at a blank division for deck change. The lug 23 of lever 21 will shift the contact 24 for the deck selection. Reversal of the direction of rotation of the spindle 26 is effected by a reversing gear comprising bevel gears 27, 28, 29 and dog clutch 31. In a mechanical modification deck selection is effected not by contact 24 but by stops 151, 152, Fig. 7. The latter determines the position of the card relative to the analysing device. The card feeling mechanism is arranged to slip in well known manner when the card meets the resistance of either of the stops. The stops 151, 152 are rendered effective alternately depending on whether a column of the upper or lower deck is required to be analysed. The stops are moved into the path of the card by an eccentric 153 on shaft 154, and a lever 155. The shaft 154 rotates once per card cycle. The lever 155 is mounted on a pin 156 fast to the casing. In the case of a deck change the clutch lever 121 and arm 158 will rock, and the pivot 157 will rise and either stop 151 or 152 will project into the card path, the clutch lever 121 being connected to arm 158 through a link 163. Specifications 128,207, [Class 106 (i)], and 535,345 are referred to.
