Title: Improvements in marking out fabrics
IPC: D06H1/00
Filed: 1947-09-22
Abstract: 630,354. Marking-out fabrics. ROTHENBORG, A. Sept. 22, 1947, No. 25702. Convention date, Sept. 20, 1946. [Class 100 (ii)] For marking-out one or more layers of fabric &c. by the aid of a needle carrying a pigment, the feed of the pigment is effected by forming a helical groove as 31, Fig. 5, in the needle 23, and causing the needle to rotate before or during the penetration of the layers of fabric. The needle 23 is carried by a spindle 12 which is splined to a hollow shaft 3 mounted in a frame 2 and adapted to be rotated by a motor 8 under control of a push switch actuated when the pigment receptacle 28 engages the fabric, or by the operating lever 20 which depresses the receptacle 28, the needle 23, and its spring mounting, against the action of which the needle moves to penetrate the fabric. The work-support 1 has a tapered front so as to engage readily under the layers of fabric, and the needle 23 cooperates with an aperture 33 in the support below which is a receptacle 34 for collecting excess of pigment. To ensure a rapid feed of the pigment, the groove 31 is arranged as shown in Fig. 5 with a left-hand thread, the needle being driven in a direction which is clockwise as viewed from above.

Patent GB-257979-A (GB)
Abstract: 257,979. Leitch & Co., Ltd., J. W., and Everest, A. E. June 2, 1925. Sulphonated aromatic amines.-Aniline, o- and p-toluidine, o- and p-chloraniline, o- and p-anisidine, p-phenetidine, a- and #-napthylamine, mxylidine, and the mixed xylidines, are sulphonated by first forming the condensation product with an aromatic sulphochloride, such as p-toluene culphochloride, and treating the sulphamino compound obtained with concentrated sulphuric acid, sulphonation and elimination of the sulpho group being effected at the same time. The sulphonation is carried out by using concentrated sulphuric acid or oleum, at a moderate temperature, followed by dilution of the product with water. The preparation of p-toluidine-3-sulphonic acid from p-toluenesulpho-p-toluidide, of aniline-4-sulphonic acid from benzene sulphanilide, and of a-naphthylamine-4-sulphonic acid from p-toluene sulphoa-naphthalide is described. The sulphonic acids may be separated or used without separation. The reaction is stated not to be effective with benzidine, tolidine, dianisidine, aminoazobenzene, aminoazotoluene, m-nitro-p-toluidine, p-nitraniline, m-nitraniline, 3-nitro-4-chloraniline, 3 : 5- din itro-4- chlorani line or 3 : 5-dinitro-p-toluidine.

Abstract: 407,403. Nailing. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(Assignees of Goddu, G. ; Winchester, Massachusetts, U.S.A.) Sept. 22, 1932, No. 26334. Convention date, Feb. 2. Addition to 372,360. [Class 89 (iii).] Relates to devices, as described in the parent Specification, for separating fastenings singly from a supply and delivering them to a point where they can readily be removed by an operator for hand use. A U-shaped member 26 is mounted at the lower end of an inclined raceway 16 which is supplied with tacks 14 by a tack-pot, not shown. The member 26 has a slot 30 which normally is in alignment with the raceway slot 22, and has an extended resilient arm 42 which is fixed to the side of the raceway. A separator finger 40 is secured to the arm 42. With the parts in the position shown, the operator removes the tack 14 which is ready in the member 26, and at the same time moves the member laterally. This movement causes the separator to release the tacks in the raceway, whilst an arm 32 on the member closes the lower end of the raceway. When the operator releases the member 26, it is returned by the resilient arm 42, returning the separator to tack-holding position and allowing the end tack to slide into the member 26. The extent of the lateral movement of the member is adjustable by means of a screw 46.

The filament is threaded in the traveller when the ring is removed, as shown in Fig. 3, the ring being then replaced, and the filament led to the waste roller 10, whereby it may be caused to engage with the flange of the bobbin by means of a rod 7 or by a finger of the operative. The waste roller may be dispensed with and the filament collected on the godet which then serves as a waste roller. The flange of the bobbin may be provided with a notch or clip to facilitate the attachment of the filament.

Title: Pulse counting apparatus

Filed: 1962-07-10
Abstract: 942,978. Electronic counters. WESTING- HOUSE ELECTRIC CORPORATION. July 10, 1962 [Aug. 16, 1961], No. 26495/62. Heading G4A. A binary counter is arranged to operate in pure binary or binary-coded decimal, in forward or reverse. As shown the counter has four stages 1-4 made up of NOR gates such as 11, 12, 14 the last two being arranged as a bi-stable pair. For forward counting control circuit 32 applies "1" to lead 29 and "0" to lead 31 over terminals 129, 131 so biasing clipping diodes such as 21, 23. If the count is to be in pure binary "0" is applied over terminal 156 to diodes 52, 54 and "1" to NOR gate 50 over input 5. Input pulses at 100 then produce "0" pulses at the output of NOR gate 11 to reverse stage 1, and the counter operates in conventional manner with reset from the output of NOR gate 57 when full capacity is reached. If the count is to be in binary-coded decimal "-1" is applied by circuit 32 to terminal 156 and "1" is removed from terminal 5. In this case the eighth pulse causes NOR gate 50 to send a signal "0" to NOR gate 50 which sends "1" to NOR gate 22, so blocking the following stages. The ninth pulse sets stage 1 to "1" and the tenth pulse sets it back to "0". NOR gate 14 then sets NOR gate 59 back to "0" through capacitor 65 so completing the cycle with transfer from the output of NOR gate 57. Reverse'counting is effected by control circuit 32 applying "0" to terminals 129, 156 and "-1" to terminal 131. The polarity on leads 29, 31 is thus reversed. For pure binary "1" is applied to terminal 5, this being omitted for binary-coded decimal.

Abstract: 927,338. Automatic exchange systems. SIEMENS & HALSKE A.G. July 25, 1961 [July 25, 1960], No. 26898/61. Class 40 (4). In an inter-exchange system employing V.F. signalling, each supervisory signal is preceded by a preparatory signal which causes a common V.F. receiver to be taken into use at the receiving exchange. The preparatory signal is not necessarily of voice-frequency but is always the same. The junctions terminate in outgoing and incoming repeaters Ug, Uk which seize when required common V.F. transmitting and receiving apparatus TSEg, TSEk. The junctions L2, L3 may be 4-wire. Assuming a call between exchanges B and C, on the occurrence of a supervisory condition at B, for example, the preparatory signal is sent from Ug and TSEg is taken into use. The receipt of this signal at Uk takes into use TSEk which sends a V.F. acknowledgment signal. The latter is received in TSEg, cuts off the preparatory signal and causes the appropriate V.F. supervisory signal to be sent. This when received cuts off the acknowledgment signal which in turn cuts off the supervisory signal, and the common apparatus is released. The acknowledgment signal may be dispensed with, provided the preparatory signal is of limited duration. Different single frequencies are employed for different supervisory conditions. The system caters for a break-in signal from the calling end as well as for the usual reply and clearing signals. On a tandem call between A and D, for example, a connection between Ug and Uk at the intermediate exchanges B, C results in circuit changes by which the preparatory signal is repeated at those exchanges whereas the V.F. signals pass straight through, although the common apparatus is taken into use momentarily. The circuits of the repeaters Ug, Uk and of the common apparatus are described with reference to Figs. 1, 2 (not shown).
