Title: Improvements in or relating to knitting machines
IPC: D04B15/00
Filed: 1931-10-16
Abstract: 381,344. Knitting-machines. HOSIERY MACHINE CORPORATION, Cumberland, Rhode Island, U.S.A.- (Assignees of Miller, M. C.; Cumberland, Rhode Island, U.S.A.) Oct. 16, 1931, No. 28816. Convention date, Oct. 23, 1930. [Class 74 (ii).] A comb 84 for aligning and supporting the needles and transfer elements 54 of a Cotton machine is secured to a bar 88 movable against a spring 94 in a bracket 56 supporting the transfer points. The coverplate for the sinkers acts as a stop for the bar 88 as the transfer points are moved downwardly from their inoperative position. In action, the needles 24 enter between the spade-shaped ends 102 of the aligning instruments and are thus caused to register accurately with the transfer points 54. During the narrowing operation the needles are supported near their hook ends by combs 112 which are moved up for that purpose. The combs 84, 112 are capable of slight lateral movement to accommodate them to slight variations of the needle line from the vertical. Fig. 1 (notshown) is a sectional view of the machine showing the general arrangement of cams and links for driving the needle bar, combs 112, &c.

Filed: 1975-07-09
Abstract: 1489295 Credit card gate BURROUGHS CORP 9 July 1975 28822/75 Heading G4V A credit card inserting and ejecting gate comprises two relatively movable portions 12, 14 each having two inclined surfaces 18, a block 20, 22 is attached to each portion 12, 14 respectively, the blocks being slightly closer together than the widths of a credit card, springs 24 urge the portions together. The blocks have inclined surfaces 26 so that when a credit card is inserted through slot 6 in front plate 2, it engages blocks 20, 22 causing the two portions to be forced horizontally and consequentially vertically so that a gap appears between the portions to allow the credit card to pass therebetween. Ejection of the card is obtained by the portions having bevelled edges 28. The portions are mounted on posts 10 which are fixed to frame 8.

Title: Axially Reciprocating Inking Roller
IPC: B41F31/15
Filed: 1967-06-22
Abstract: 1,195,713. Inking roller. BALDWIN-GEGENHEIMER CORP. 22 June, 1967 [28 Nov., 1966], No. 28947/67. Heading B6C. [Also in Division F2] An inking roller is rotated by contact with further inking rollers and is so constructed that the rotary motion is partially converted into axially reciprocating movement. Figs. 2 and 3 are longitudinal sections through each half of the roller which is in rolling contact with a further roller 4. The roller comprises two stationary spaced-apart colinear spindles 6 supported in a frame 8; an outer sleeve 10 rotating in contact with the roller 4, and an inner sleeve 12 rigidly fixed to the outer sleeve 10. Fixed to the spindles 6 and extending between them is a stationary body 18 on which is mounted various gears; the rotational movement of outer sleeve 10 is transmitted through a cup-shaped tubular member 15 and a key element 16 to bearing 28. This bearing causes tubular member 22 to rotate which in turn causes rotation of a bevel gear 24 mounted on member 22; gear 24 actuates a series of further spur and bevel gears 30, 33, 41, 37, 39 and 44, the last of these causing a second tubular member 40 to rotate. A row of cam followers 46 mounted on this member 40 interact with cam surface 47 carried on the inner surface of inner sleeve 12 (also Figs. 4, 5, not shown), the cam surface being designed so as to reciprocate the outer and inner sleeves 10, 12 along the axes of spindles 6. The gear means are preferably selected so as to effect a speed reduction.

The glass contains substantially no Li2O or TiO2.  In addition, the glass may contain, up to a total of 20%: Na2O and/or K2O, up to 6 in total; MgO, CaO, SrO, and/or BaO, up to 10 in total, PbO, up to 10; B2O3, up to 10.  The nucleation catalyst may be one or more of: P2O5, up to 6.0; MoO3, up to 5.0; ZrO2, up to 7.5; preferably the catalyst is either P2O5 above, or MoO3 with either P2O5 or ZrO2.

If the temperature is less than 1,000 DEG  C., the temperature is again raised at not more than 10 DEG  C. per minute to a second holding stage at 1000-1250 DEG  C. The cooling rate from the final temperature may be up to 10 DEG C./min. The major crystalline phase is zinc orthosilicate 2ZnO.SiO2. Other crystalline phases are zinc spinel ZnO.Al2O3, "galinite"; quartz, SiO2; and mullite, 3Al2O3,2SiO2.  Coefficient of thermal expansion is may be 28.0 to 115.4 x 10-7/ DEG C.

Abstract: 536,299. Trueing grinding-wheels. THURLEY, G. S., and BRITISH GEAR GRINDING & MANUFACTURING CO., Ltd. Nov. 8, 1939, No. 29664. [Class 60] A grinding wheel for precision gear grinding has its profile generated to involute form by a diamond tool controlled by a tangent bar cooperating with a base circle cylinder 1 has means for moving the diamond independently of the involute generating mechanism to form a wheel which will cut teeth having an undercut arcuate portion lying within the base circle. The cylinder 1 is connected by flexible tapes 3-5 to a tangent bar 2 carrying a slide 12 fitted with a projection 17 on which the holder 11a of the diamond tool 11 rotates on the bearings 18. The cylinder 1 is mounted on an arbor 14 which is eccentrically mounted on a shaft 15 which has eccentric mounting points 16 on the centre of the cylinder 1. By these eccentric adjustments the portion of the effective part of the cylinder may be altered to vary the pressure angle of the gear being formed. Also cylinders of size different from the theoretical size may be used to obtain modifications of the theoretical profile. The diamond may be pivoted about the projection 17 by a handle to obtain an arcuate profile of adjustable radius on the wheel below the base circle whereby an undercut is produced on the wheel being ground. The tangent bar is mounted on a slide 22 on a carrier 23 which is fitted with a handle 20 by which the apparatus is rocked round the arbor 14 to shape the involute on the wheel 13. The generating cylinders may also be of modified shape to give relief to the resultant gear teeth to compensate for deflections under load. The cylinder and tangent bar may be replaced by a gear and rack mechanism. The apparatus may be mounted on the machine in place of the gear to be ground when the wheel profile requires to be trued.

Abstract: 841,577. Transistor amplifying circuits. PHILCO CORPORATION. Sept. 28, 1956 [Sept. 29, 1955], No. 29679/56. Class 40(6). A gain controlled transistor amplifier comprises a parallel tuned input circuit coupled to the input electrodes of a transistor through a reactance having a high value compared with the input resistance of the transistor so that changes of input resistance of the transistor as the gain control voltage varies can be made to influence the bandwidth of the amplifier in a desired manner. The Figure shows a transistor IF amplifier comprising a tuned inter-stage coupling circuit 46 and a coupling capacitor 60 having a reactance high compared with the input resistance of the transistor 36. An AGC voltage is applied to the base electrodes of two I.F. transistors causing the input impedance to increase as the signal increases. Capacitor 60 may have such a value that the band width remains constant as the input resistance of transistor 36 changes or may provide over-compensation so that the changes of resistance of the collector 45 also do not change the band-width of the amplifier. The capacitor 60 also helps to provide an impedance match between the circuit 46 and the transistor 36. In an alternative circuit Fig. 2, not.shown, the transistor is connected in grounded emitter configuration. An inductor could be used in place of the capacitor.
