Title: Improvements in card sorting machines
Filed: 1956-09-11
Abstract: 833,461. Sorting record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 11, 1956 [Sept. 14, 1955], No. 27719/56. Class 106 (1). A card-sorting machine comprises a plurality of card-receiving pockets two of which 9-1, 9-2 each serve to receive the overflow of cards from the other, the cards of a particular classification being directed into one of the pockets until it is filled and following cards of that classification then being directed into the other pocket, an indicating lamp being associated with each pocket which becomes operative when the pocket is filled. There are interlocking means for the indicating lamp circuits so that the lamp of the first filled pocket stays lit until the cards are removed from it. This allows the cards in the two pockets to be re-associated in the correct order. The provision of overflow pockets for the " 9 " class may be necessitated if a large proportion of the cards being sorted are in that class. A similar provision may be made for other .classes as well. The pocket selecting magnets 80-12, 80-9-1 are energized as usual by a circuit through the card-sensing brush 128 and a commutator arm. The " 9 " contact of the commutator is normally connected by a relay contact R20-2 to the selector magnet 80-9-1 for pocket 9-1 but when latching relay R20LP is energized the overflow pocket magnet 80-9-2 is connected and the cards are accordingly diverted into this second pocket. When pocket 9-1 is filled to capacity a contact C9-1 is closed to energize relay R9-1. This energizes relay R20LP through contacts R9-1b (normally open) and contacts R9-2a (normally closed). Transference of contacts R20-1 causes indicating lamp L9-1 for the first pocket to light through contacts R9-1c. When the second pocket 9-2 is full contacts C9-2 close to energize relay R9-2 and complete a circuit through contacts R9-1a to the stop relay R21 so that the machine stops. While the first pocket is still full the relay R9-2 is ineffective to trip the relay R20LP by energizing trip coil R20LT because contact R9-1b is still transferred. The lamp L9-1 therefore remains on showing that pocket 80-9-1 was the first to be filled. If, while the second pocket was being filled, the first pocket was emptied the contacts C9-1 open and relay R9-1 is deenergized so that when the second pocket is full no circuit is made through stop relay R21 and the machine continues running. A circuit is made through contacts R9-2b to energize trip coil R20LT so that contacts R20-2 return to normal position and " 9 " class cards begin to be fed to pocket 80-9-1 as before. Also lamp L9-1 is put out and lamp L9-2 is put on indicating that the pocket 80-9-2 is full and, when both pockets are filled, that it was filled first. Specification 242,654 is referred to.

IPC: B29C48/90
Filed: 1958-09-01
Abstract: <PICT:0852228/IV(a)/1> <PICT:0852228/IV(a)/2> An apparatus for cooling and regulating the size of an extruded tube 8 of plastic material comprises an elongated annular member 10 having a series of separate, circumferentially continuous, spaced bands 43 and recesses 44 and having temperature control means to cool the tube 8 to a temperature at which the surfaces of the tube will not stick together.  The cooled tube may be flattened by rollers or cut to a sheet.  The temperature control means may be fluid jackets differentially arranged.  Air under pressure may be admitted to the interior of the tube to force it into contact with the size-regulating member.  The movement of the tube through the member is said to draw air into the member so that the tube "floats" on air and does not contact the member.

Laminar springs.-A laminated spring is provided with a compound master-plate comprising two or more plates 1 - - 3, Figs. 1 and 2, extending the full length of the spring and connected together at their extremities to offer combined resistance to torsion, rebound beyond the unloaded position, and side motion by a stirrup link 4 pivotally connected to a sprung or unsprung part by a single anchor pin. The surface of the link 4 in contact with the underside of the plate 3 is flat and of sufficient length to act as a guide without jamming against the plate 3. In a modification shown in Fig. 3, suitable for light vehicles, the stirrup link is replaced by a threeholed link the centre hole of which receives the anchor pin. The two outer holes are preferably elongated to permit the necessary relative movement between the plates, but if these holes are not elongated, the plates are arranged barely to touch each other in the rebound position. When only two plates are used, they are connected to the outer holes, the centre hole receiving the anchor pin as before. In a further modification shown in Figs. 4 and 5, the ends of the plates, preferably two, are carried on one anchor pin, the plate 1 'being definitely anchored to the pin while the plate 2 has elongated eyes engaging the pin. To give greater flexibility to the overhanging portion, the plates 1, 2 may cut away in tapering fashion as shown respectively in full and dotted lines in Fig. 5.

Abstract: 711,764. Filing papers. BRINKMANN TO BROXTEN, R. Nov. 10, 1952, No. 28306/52. Class 146(1) In a suspension filing system in which index strips 4, or cards, are arranged between suspended filing cards 8, one or more lifting devices for the index strips or cards are provided on the floor of the cabinet and consist of a horizontal lifting rod 1 with articulated arms 13 which can be brought from the oblique position into a vertical or approximately vertical position, to raise the strips 4, by means of a tie rod 15 and hand lever 18 articulated thereto. Each series of index strips 4 is connected to its lifting rod 1 by means of a connecting plate 2 having an enlarged, head. 3 which fits into a correspondingly shaped slot in the strips 4. The lifting rod 1 is provided with end rollers 9 which are guided between pairs of strips 12 on the end walls 10, 11 of the cabinet and the arms 13 have rollers 14 to facilitate movement of the device. The tie rod 15 is hinged to the lever 18 either by a pin and slot connection or, as shown, by an intermediate rod 19 passing through a aperture 16 in the front wall 10, the lever 18 being hinged at 17 to a bracket 24 extending out from wall 10. To allow an additional rise of rod 1, or shorter arms 13, ramps with a flat top may be provided, in front of each roller 14, the tie rod 15 then being connected to lever 18 by pin and slot and the aperture 16 being enlarged to allow the raising of the tie rod 15. To prevent the cards 8 from being inadvertently raised with the index strips 4, rails 6 are hinged at 5 to the side walls of the cabinet, so as to lie over the suspension tabs 7 of the cards 8. In the final raised position of the lifting device the arms 13 pass a few degrees over the vertical so as to maintain the index strips 4 in the raised position.

Control mechanism:-In rotary grip Bowden &c. control devices for actuating brakes &c. on motorcycles &c., of the kind provided with independent controlling means for an additional Bowden or like transmission device, such supplementary controlling means comprises a slidable member adapted to be actuated directly by thumb or finger and to be retained in positions of setting by positive or frictional engagement with its guide member or housing. The carrying means 1 for the supplementary actuating device is integral with or secured to the fixed clamping member 2 at one end of the twist grip member 3. In one form, Fig. 1, the actuating member 4 slides between flanges 16 on the supporting plate or bracket 1 and transmits a thrust to the casing or outer member 8 of the Bowden mechanism when pressure is applied to its head 6, the cable or inner member 9 being anchored to a fixed stud 10. Under pressure of a spring 14, the toothed edge 12 of the member 4 engages a fixed tooth or projection 13 to maintain positions of adjustment; this arrangement of teeth may be reversed. A cover plate 17 is provided. In a modification, Fig. 4, the actuating member 4 slides in a casing 1 the upper portion of which is substantially cylindrical to allow entry of the Bowden casing or outer member 8 as the slidable member is retracted, the Bowden cable being anchored in the remote end 11 of the casing. In a further modification, Fig. 8, the fixed casing 1 is tubular and is clamped in a split seating formed on the twist grip clamping ring 2. The slidable member 4 is of semi-circular cross section with an end abutment 18a forming the seating for the Bowden casing, the cable being anchored by its nipple 11 in the fixed casing 1.
