Title: Improvements in sintered carbide compositions
IPC: C22C29/08
Filed: 1955-04-25
Abstract: A cemented multi-carbide composition consists of 58 to 90 per cent by weight of WC crystals ranging in size from 25 to 250 microns, a major portion being from 25 to 150 microns, and 5 to 32.5 per cent by weight of at least one of the carbides of Ti, Ta, Zr, Nb, sintered into an integral mass with 1.5 to 10 per cent by weight of the sintered product of a binder selected from Co, Ni, Fe or their mixtures.  The WC crystals are much larger than normally used but the other carbides have normal grain size i.e. in the range 0.5 to 10 microns; whilst Co is the preferred binder.  The method of manufacture is conventional save that the fine grain carbides and binder metal are first ball milled together with a little WC if desired; most of the WC is however then added and the mixture ball milled for a relatively short time to avoid excessive attrition of the coarse WC crystals.  The product is useful for cutting and machine tools of various kinds. Examples show compositions of (a) WC 74.3 per cent, TiC 21.4 per cent, Co 4.3 per cent; (b) WC 64.3 per cent, TiC 18.3 per cent, TaC 13.3 per cent, Co 4.1 per cent: (c) WC 65.4 per cent, TiC 27.6 per cent, Co and Ni 3.5 per cent each: (d) WC 63 per cent, TiC 18 per cent, TaC 12.9 per cent, Co 6.1 per cent: (e) WC 61.5 per cent, TiC 17.6 per cent, TaC 12.7 per cent, Co 8.2 per cent: (f) WC 68.1 per cent, TiC 14 per cent, TaC 10.1 per cent, Co. 7.8 per cent: (g) WC 59.1 per cent, TiC 18.8 per cent, TaC 13.7 per cent, Co 8.4 per cent.

Abstract: 1,223,141. Photo-electric reading heads. GEORGE RICHARDS & CO. Ltd. March 14, 1968 [March 15, 1967], No.12093/67. Heading G1A. A reading head includes a number of photosensitive detectors each arranged to receive an image and comprises also a source of light arranged to illuminate a part of the sensitive surface of each detector displaced from the part where the image appears and an individual adjustor for each detector to adjust the amount of light falling on the displaced part of the sensitive surface. As used in apparatus for determining the position of a grating as described in Specification No.12496/67, light from a lamp 14 is directed by a collimating lens 15 on to the surface of a reflection grating 13 whence it is focused by a lens 16 on to four photosensitive detectors 17. The cursor 12 through which the grating is viewed is inclined at an angle of about 1 degree to the grating 13 with the result that light reflected from the cursor surround follows a path X and falls on the photo-sensitive detectors 17 at a point displaced from the image of the grating. The amount of reflected light falling on the detectors 17 is adjusted by a screw 22 whereby the dark currents of the detectors may be equalized. The "full illumination" currents from the detectors may be equalized by electrical means.

Title: Improvements in or relating to circular independent needle knitting machines with holding down sinkers or web holders, and to fabric produced thereon
Inventor: ROWLETT JACK HIGGINSON
IPC: D04B9/00
Filed: 1960-04-06
Abstract: 929,754. Knitting-machines. FOISTER, CLAY & WARD Ltd. June 26, 1961 [April 6, 1960], No. 12186/60.. Class 74 (2). A circular knitting-machine has a sinker bed or dial with abnormally wide tricks to receive either thick sinkers or a plurality of thin sinkers so that unusually rounded sinker loops are formed, an auxiliary feed point F<SP>1</SP> at which elastic yarn is fed to selected needles 9<SP>1</SP> and at the main feed point F means which move the sinkers 14 inwards earlier than normally to draw loops over the tops of the sinkers and also means which lower the needles 9 more than normally to form elongated stitches with the elastic yarn locked in the stitches formed by the selected needles. As shown, at main feed point F, feeder 1, forward and reverse stitch cams 2, 3 and guard cams 5, 6 and 7 are provided. Needles 9<SP>1</SP> have longer jacks than the remaining needles 9<SP>11</SP> so that engagement of the jack butts by cams 12, 13 raises needles 9<SP>1</SP> sufficiently to receive elastic yarn from feeder 8 in the open latches without knitting it after which the needles are lowered by cam 19. All needles 9 are lowered by cam 24 preparatory to the selection of needles 9<SP>1</SP>. The sinker cam ring has a cam track 15 in which the sinkers 14 run, being normally moved inwards by cam portion 16, a pivotable cam 17 effecting abnormal earlier inward movement of the sinkers at feeder F. At auxiliary feed point F<SP>1</SP> a further movable cam 18 is biased into operative position. A bolt cam 20 below stitch cam 2 at the main feed increases the length of stitches drawn. Timing mechanism or a control drum controls feeder 8 and cams 17, 18, 19, 20 and 24. In a modification, every other needle 9<SP>111</SP> has no jack while 'the remaining needles 9<SP>1</SP>, 911 have alternately long and short jacks. Thus normally only every fourth needle 9<SP>1</SP> takes the elastic yarn but if feeder 8 is lowered every other needle 9<SP>1</SP>, 9<SP>11</SP> will take the yarn. One or more lengths of elastic yarn may be run on to the needles before knitting commences so as to be incorporated in the first course of the welt. The 1 x 1 or 1 x 3 incorporation of elastic yarn produces a mock rib fabric for sock tops, or cuffs or waists of other garments.

Title: Improvements relating to brake linkages
IPC: B60T11/08
Filed: 1962-03-30
Abstract: 977,203. Brake transmitting mechanisms. H. O. SCHROTER. March 30, 1962 [April 1, 1961], No. 12376/62. Heading F2E. A brake linkage includes a lever 26 arranged to provide a substantial increase in the velocity ratio of the linkage during the brake application stroke, a spring 31 connected to the lever 26 and through which the brake actuating force is initially transmitted, and a catch mechanism, e.g. a ratchet mechanism 40, 41 arranged to become engaged at a predetermined stage of the application stroke and when so engaged to prevent the spring being further stressed and to transmit further actuating force positively to the output member of the linkage. As shown, the lever 26 has rigidly secured thereto for rotation therewith a radius arm 38 which is pivotally connected to a connecting rod 15 in turn pivotally connected to an input lever 10. The spring 31 is retained between a washer 32 held by a nut 33 on a bolt 30 which is pivotally secured to one arm of the lever 26 and a lug 34 formed on a lever 24 pivoted at 25 on the other arm of the lever 26. A chain linkage 22 pivotally connects the lever 24 to the output T-piece 16. Movement of the lever 10 by an associated brake lever or pedal causes the lever 26 to pivot with a much greater angular velocity which pivotal movement is transmitted via the bolt 30, spring 31, lever 24 and chain linkage 22 to the output piece 16 to take up slack in the brakes. Further movement of the lever 10 causes the spring to be compressed introducing lost motion between the levers 26, 24 and applying increased thrust to the brakes. Before the spring becomes completely compressed the pawl 41 engages the teeth 40 on the lever 26 which prevents further compression of the spring 31 and allows further movement of the lever 10 to be transmitted directly to the chain linkage 22.

Patent GB-932875-A (GB)
Title: Pederine and pseudopederine
IPC: C07D309/30
Filed: 1962-04-02
Abstract: The biologically active substances pederine and pseudopederine (a new substance) are extracted from dried insects of the genus Paederus by grinding them in the presence of an ether or a hydrocarbon solvent, e.g. n-hexane or benzene and thereafter extracting the ground bodies with the solvent used, e.g. by decantation, Soxhlet extraction or percolation through columns. The required substances may be separated from the solution thus obtained by countercurrent partition between water and the solvent used.  In the example extraction is by ether, the ground bodies being held in columns "stacked" in series, a fresh column being placed at the bottom of the stack when the topmost column is exhausted and is removed.  The ethereal solution is partitioned against water saturated with ether and the pederine and pseudopederine are recovered separately from different fractions of the ether phase.  Reference is also made to the use of chromatography on activated alumina columns to separate the pederine and pseudopederine from unwanted material in the extract prior to the separation of these two substances by countercurrent partition.

Title: Phase-correcting low-pass electric wave filters
IPC: H03H7/01
Filed: 1939-04-27
Abstract: 528,133. Impedance networks. HAZELTINE CORPORATION. April 27, 1939, No. 12691. Convention date, May 18, 1938. [Class 40 (iii)] In a phase-correcting network, the phase shift is a multiple of # at selected points in the working range; the phase characteristic is approximately linear except in the neighbourhood of the cut-off frequency; the network is terminated by shunt capacitance, so that it may be used in conjunction with the interelectrode capacity of a thermionic valve; and there is a small negative mutual inductance between elements of the filter. The low-pass network shown in Fig. 1b, in which the series inductances L, L have mutual inductance M, is equivalent to two constant-k half-sections having mid-shunt outer terminations and separated by an m-derived tee section with negative inductance in the shunt arm, Fig. la (not shown). In the m-derived section, m is chosen to be greater than 1, and the phase lag is 2 # at the cut-off frequency and # at an intermediate frequency dependent on m. The use of two m-derived sections, Fig. 1d (not shown) gives a phase shift which is a multiple of # at two selected frequencies in the pass range, and a similar result is given by the network shown in Fig. 2A, where the inductances L1, L1 are mutually coupled. The inductance 45 may be omitted if the two selected frequencies are suitably rotated. The inductance L2 may be coupled to L1, L1, Fig. 3a (not shown). A valve 10, Fig. 4, having interelectrode capacitance represented in two parts 12, 13 may be coupled to a valve 11, whose input capacitance is represented at 14, 15, through a circuit equivalent to that shown in Fig. 1 b and comprising inductances 18, 19 corresponding to L, L, while the parts 13, 14 of the interelectrode capacitances correspond to Cl, Cl and the capacitance 20, corresponding to C2, comprises at least in part the capacitance between the inductances and earth. The mutual inductance M is provided by a link circuit 21. The input shunt impedance of this coupling is maintained by a dead-end filter 12, 16, 17, 26 of the kind described in Specification 524,548. A grid leak resistance 22 and blocking condensers 23, 24 are provided.
