Title: Improvements in and relating to bridges for frequency measuring
IPC: G01R23/02
Filed: 1926-11-16
Abstract: 268,287. Felten &. Guilleaume Carls-- werk Akt.-Ges. March 24, 1926, [Convention date]. Frequency, measuring.-Fig. 1 shows a known. Wheatstone bridge for measuring the frequency of alternating current supplied from a source W. Resistances R3, R4, which are variable but always equal, form two arms of the bridge, the third arm being formed by a condenser C1 and a constant resistance R1 in parallel and the fourth arm by a condenser C2 and a constant resistance R2 in series. It is shown in " The Post Office Electrical Engineers Journal," Vol. 16, part 2, page 171, that when the bridge is balanced the frequency is inversely proportional to the equal value of the resistances R1 R2, and that the bridge may be made direct reading by forming each of these resistances of a number of variable resistances in parallel, each of which is employed for the adjustment of one digit of the number representing the frequency. According to the present invention, the use of resistances of high values is avoided by distributing the resistances corresponding to the lowest frequency to be measure over the lowest steps of the other frequency units as shown in Fig. 2. in which T, H, Z represent the resistances corresponding to the thousands, hundreds, and tens of the frequency. At each tapping point the upper figure shows the portion of the frequency corresponding to the set resistance in the absence of the other two resistances, the total frequency being the sum of the three portions corresponding to the adjusted' resistances. The lower figures represent the portions of the frequency, which are read directly as integral thousands, hundreds, and tens, the sum of the lower figures being always equal to the sum of the upper figures.

Title: Improvements in terminal circuit arrangements for signal circuits
IPC: H04L12/00
Filed: 1952-11-17
Abstract: 729,945. Telegraph exchange systems. SIEMENS & HALSKE AKT.-GES. Nov. 17, 1952 [Nov. 16, 1951], No. 29024/52. Class 40 (3). In a terminal circuit arrangement for a line signal circuit operated in either of two directions with single current working, comprising a receiving relay for signals arriving through the signal circuit and a movable contact member oontrolling the signal transmission for the terminal in the other direction, the contact member in functioning to transmit the signals short-circuits the line circuit in its operative position by its engagement with an associated fixed contact and by-passes the winding of the receiving relay which in the inoperative position of the contact member is connected in the line circuit, and at the same time establishes a holding circuit for the said winding through the second fixed contact and a line equivalent impedance which is shunted in the inoperative position of the movable contact by its engagement with a further fixed contact. In the application, Fig. 4, to a teleprinter exchange system, the circuit arrangement links a single current line a, b of a subscriber Tn with a double-current line a1, b1 and a2, b2 associated with a transmission channel or exchange line. In the transmission from a subscriber Tn, the breaks at the transmitting contacts SK deenergize winding I of the exchange receiving relay A which, controlled by the current through the winding II from the exchange battery TB moves its armature a to the marking position Z to transmit signals on the outgoing line a2, b2. For signals transmitted to the station Tn by the operation of the polarized relay B over the lines a1, b1, the movement of the armature (moving contact member) b to the mark position Z short-circuits the line a, b and controls the receiving magnet EM of the subscriber's teleprinter. During the transition of the armature b from the space contact T to the mark contact Z, current flows through the line a, b, impedance Rh and winding I of the relay A, in addition to a discharging current from the capacitor C so that its armature is retained in the opening position in which it is retained when the armature b engages the mark contact Z by current from the battery TB through the impedance Rh which is shunted when the armature b is against the space contact T. A control relay with two windings, one connected between the b wire and a point common to the two windings I, II of the relay A and a second replacing or connected in series with the impedance Rh may be included to indicate the progress or state of the connection. This relay is arranged to be slowto-release and not to be de-energized except in response to a long mark indicating the end of the message. A similar control relay may be included between the line a2 and the mark contact Z engaged by the armature a of relay A. A modification, Fig. 6 (not shown), employs a single-wire connecting line with an earthreturn instead of the two lines a, b.

Abstract: 621,380. Printing-machines. HOE & CO., Ltd., R., and TOFT, N. P. Nov. 2, 1945, No. 29204. [Class 100 (ii)] Inking-apparatus.-In a doctor blade mechanism for a rotary intaglio printing machine, the blade holder is pivoted to one of a pair of arms of different lengths, the shorter arm being remote from the printing cylinder, and is movably connected to the other arm, and there is provided a first mechanism to rock the holder about its pivot to raise and lower the blade from and into contact with the cylinder, a second mechanism to move both arms together to carry the holder from an operating zone adjacent the cylinder to an inspection zone remote therefrom, and interlocking means to prevent operation of the second mechanism to return the holder to the operating zone until the first mechanism has been operated to move the holder to blade-lifted position. The holder 6, Fig. 3, of the doctor blade 3 is clamped to three arms 8 fixed on a shaft 9, the centre arm 8 having an extension 8<SP>1</SP> carrying a head 12, Figs. 3 and 4. The shaft 9 is journalled in three arms 10, 11 pivoted on a shaft 18 supported in a reciprocable frame 43<SP>2</SP>. A block 16 pivoted at one end of an arm 19 shorter than the arms 10, 11 and fixed to a shaft 20 in the frame 432, has a slot 15 engaged by a pin 14 eccentrically mounted on a shaft 13 journalled in the head 12. Movement of a handle 17 connected to the shaft 13 rocks the arms 8, 81 and the carrier 6 on the arms 10, 11 to raise and lower the blade from and into contact with the cylinder 2. A spindle 24 carrying a hand wheel 25 has a worm 23 engaging a worm-wheel 22 fixed to the shaft 20, whereby the shaft 20 can be rotated to swing the whole doctor blade mechanism about the shafts 18, 20 away from the cylinder 2 into an inspection zone. The spindle 24 also carries a disc 26, the edge of which is engaged by wedge-portions 31, 32 of two arms 27, 28 pivoted at 29, 30 and spring- urged apart to press the portions 31, 32 normally into contact with the disc 26. The inner cable 34 of a flexible transmission device is fixed to the outer end of the arm 28 and the outer casing abuts the arm 27; at the other end the cable 34 is fixed to an extension of the head 12 and the outer casing 35 to an extension of the block 16. When the shaft 13 is rotated to lift the blade 3, the head 12 is moved away from the block 16 and the outer ends of the arms 27, 28 are thus moved together releasing the braking action of the wedge-portions 31, 32 on the disc 26. Thus, the operation of the hand wheel 25 is permitted only when the blade is raised from the cylinder. Specification 594,087 is referred to.

Patent GB-636372-A (GB)
Title: Production of synthetic lubricating oil
IPC: C10G50/02
Filed: 1947-11-05
Abstract: Lubricating oils are prepared by polymerizing an a -olefin to a polymer in the lubricating oil boiling range in the presence of a polymerization catalyst having little or no alkylation activity under the polymerization conditions and a diluent, and alkylating the polymer so formed with an isoparaffin or naphthene in the presence of an alkylation catalyst having little or no polymerization activity under the alkylation conditions. Preferably, polymerization is allowed to proceed until a polymer of the desired characteristics is produced, the catalyst then being withdrawn or killed or converted into an alkylation catalyst by addition of a promoter such as hydrogen halide when a Friedel Crafts' type catalyst is used for the polymerization.  The isoparaffin or naphthene may be used as the diluent in such a case since little alkylation occurs in the absence of the promoter. Other alkylation catalysts referred to are sulphuric acid, hydrogen fluoride or fluorosulphonic acid.  The a -olefin may be butene to heptene or higher and the isoparaffin isobutane to isoheptane or higher.  Substituted naphthenes such as methyl cyclohexane or methyl cycloheptane are preferred.  Temperatures of about 85 DEG  F. are suitable for both reactions but from about 70-250 DEG  F. may be used and may differ in the two stages.  Results are given of the treatment of pentene-1 in isopentane with aluminium chloride as polymerization catalyst; hydrogen chloride being added after 30 mins. to form an alkylation catalyst.  The Specification as open to inspection under Sect. 91 comprises also the simultaneous polymerization and alkylation of a -olefins and gives results of a modified treatment of pentene-1 in isopentane, hydrogen chloride being added throughout as promoter. This subject-matter does not appear in the Specification as accepted.

Abstract: 740,960. Temperature change detectors. GRAVINER MANUFACTURING CO., Ltd., MATHISEN, A., and WILKINSON SWORD CO., Ltd. June 27, 1952 [Aug. 3, 1951], No. 29734/54. Divided out of 740,884. Class 36. A temperature change detector comprising coaxial conductors separated by glass is made by assembling the conductors with glass interposed therebetween, heating the assembly to soften the glass and applying pressure to the softened glass in a direction parallel to the longitudinal axis of the conductors so that it is forced into intimate contact with both conductors and fills all the space therebetween. An apparatus for making the detector comprises guide brackets 112 mounted on a vertical frame 110 and carrying bushes 116 to clamp the outer conductor tube b or a guide tube 139 aligned therewith. A gas burner 120 arranged around tube b is mounted on a vertically movable trolley 123. The conductors a and b, separated by alternate glass tube lengths and ceramic beads, are mounted with their lower ends secured by brackets 129 and 128 respectively. The upper end of conductor b is secured in bracket 127a which also holds the lower end of guide tube 132. Glass tube lengths alternating with ceramic beads are threaded on the part of conductor a within tube 132, and a pusher tube 131, slidable within tube 132, encircles the upper part of conductor a, the end of which passes over pulley 142 and carries a tensioning weight 142a. Tube 131 carries a weight 141. The burner 120 is moved upwards along tube b by motor 124, progressively softening the glass, which is then pressed by the weight of tube 131 to cause it to embed the ceramic beads and completely fill all the spaces between the conductors. As tube 131 descends the bushes 116 are successively opened to allow passage of the weight 141. This apparatus is also described in Specification 740,884.
