IPC: H04B11/00
Filed: 1929-12-06
Abstract: 343,635. Determining bearings acoustically. PINTSCH AKT.-GES., J., 71, Andreasstrasse, Berlin. Dec. 6, 1929, No. 37490. Convention date, Dec. 13, 1928. [Classes 13 and 118 (ii).] A method of subaqueous sound direction determining consists in sending out from one point an undirected sound and a directed rotating sound beam in fixed sequence to one another. Three modifications are described. (1) The undirected sound is emitted and, after a definite interval, the directed beam commences to rotate at a known speed from its known zero position. The time interval between the reception of the undirected and directed sounds at any point indicates the direction of the source from that point. The time interval may be measured by a stop-watch graduated directly in angles. (2) The undirected sound may be emitted at known intervals during the rotation of the directed beam, a stop-watch then becoming unnecessary. (3) The undirected sound may be emitted continuously during the rotation of the directed beam, the latter thus causing by interference a maximum or a minimum sound in every direction in turn. Fig. 1a shows a rotatable transmitter having a diaphragm M and a gas-filled transmitter casing G. Instead of a rotating transmitter, a series of fixed instruments, arranged in a straight line, a " V," a triangle, or in a circle, the transmitter being energized in the correct phases to produce the rotating beam, may be used. Both the rotating and the undirected sound may be produced by a circular group of transmitters, Fig. 7, in which the undirected field is produced by the transmitters 1, 3, 5, &c., and upon this field is superimposed in turn the energy of the transmitters 2, 4; 6, 8, &c. In order to avoid interference, the undirected and directed sounds may be of different pitches. The two groups of transmitters may also be arranged in different planes.

Abstract: 359,794. Automatic exchange systems. SIEMENS & HALSKE AKT.-GES., Sie. mensstadt, Berlin. Dec. 12, 1930, No. 37575. Convention date, Dec. 12, 1929. [Class 40 (iv).] The later choice trunks leading to the final selector stage are multipled over several levels of the group selectors and terminate in linked final selectors, the one serving the appropriate group of lines being selected in accordance with the route of access. Fig. 1 shows three groups of final selectors LW accessible over three levels of the group selectors GW, the later choice trunks VL5, VL6 being connected to each of the levels and terminating in three linked final selectors, one from each group. The linked final selectors are controlled by a common set of relays. Linked final selectors. Fig. 2. Assuming the trunk VL is seized over the inlet Z2, relay C2 energizes over the test wire and connects up release relay B. Impulses received over the a wire are repeated by line relay A to the vertical magnet H2 of the appropriate switch W2 in series with relay V(I) which holds up throughout the train by virtue of its short-circuited winding II, and then falls back and connects up relay U(I). Relay M2 energizes at the first vertical step. Succeeding impulses are repeated to the rotary magnet D2 in series with relay V(I), relay U being held over winding II. If the wanted line is free, test and switching relay P energizes on the relapse of relay V and initiates ringing under the control of relay V(III), which is connected first to an interrupter LU and when relay U falls back to a 5-second interrupter S. Relays A, Y are energized, by the reply of the called party. Upon release by the calling party, relays C2, B, P fall back and the rotary magnet D2 operates in a self-stepping circuit to drive the wipers to an end position from which they are restored to normal. Modification. The circuits may be arranged so that all the final selectors are set by the incoming impulses, and an individual switching relay is energized according to the route of access.

Title: Improvements relating to earth leakage protection
Inventor: BALDWIN HAROLD TOWNLEY
IPC: H02H3/17
Filed: 1962-10-05
Abstract: 1,010,828. Protective arrangements. BALDWIN & FRANCIS Ltd. Sept. 30, 1963 [Oct. 5, 1962], No. 37813/62. Heading H2K. [Also in Division H3] In an earth leakage protective arrangement for a three-phase supply system having a neutral point 22, a source of direct current 21, 20 has one terminal earthed and its other terminal connected to the point 22 and thence via an impedance to earth, a protective relay being controlled by the voltage across the impedance so as to be normally in a operated condition, but dropping out on reduction in voltage across the impedance due to an earth fault establishing an alternative circuit in parallel with the impedance. In the arrangement shown, the impedance is a Zener diode Z which normally conducts and renders a transistor T conducting. This permits a small alternating current to flow from a secondary winding 30 through the Zener diode Z and the base-emitter circuit of the transistor T so that an alternating signal is produced at the collector of the transistor. This signal triggers a controlled rectifier 35 so that the relay R is energized and maintains its contacts 15 closed to energize the no-volt coil of a circuit breaker 9. In the event of an earth fault, the voltage across the diode Z is reduced so that the diode Z ceases to conduct the direct current and the transistor T ceases to conduct with the loss of the triggering signal for the controlled rectifier 35. Thus the relay R is no longer energized, contacts 15 are . opened and the circuit-breaker 9 is tripped. The Specification describes in some detail how the failure of components would result in the dropping out of the relay R so that the system is fail-safe.

Title: Purification of pentaerythritol
IPC: C07C31/24
Filed: 1959-11-09
Abstract: Crude pentaerythritol solution containing pentaerythritol formals is purified by maintaining the solution in an aqueous strong acid at an elevated temperature to hydrolyse the formals and simultaneously or subsequently treating the acid solution with ozone.  Alternatively the formals may be hydrolysed by treating the solution with a strong acid cation exchange resin. The starting solution may be obtained by condensation of formaldehyde with acetaldehyde and sodium hydroxide in aqueous medium.  The aqueous strong acid used is preferably sulphuric acid.  The treatment with acid is preferably carried out at 90-105 DEG C. and the treatment with ozone is preferably carried out at the same temperature.  Pentaerythritol may be obtained from the purified solution by crystallisation.  Specifications 757,564, 799,182 and 936,083 are referred to.

[Also in Division E1] In a window assembly comprising a window element 15 slidable in a frame 13, a flap 23 pivoted to the frame at 24 is arranged to form a weather seal between the frame and element 15 when the latter is in its closed position, as shown, and is moved to its open position by a spring 31 when the element is moved away from its closed position. The flap is closed and held in its closed position by engagement of the top rail 28 of element 15 with projections 29 formed on members 25 secured to each side of the flap. The window assembly includes a second element 16 which moves upwardly as element 15 moves downwardly, and vice-versa, and the bottom of the window frame is provided with a vertical baffle 20 having a sealing strip 21. Baffle 20 is of such height that no opening occurs at the bottom of the window when element 15 has been moved sufficiently to allow flap 23 to open. Elements 15 and 16 are moved in opposite directions by pinions (14, Fig. 2, not shown) mounted one on each side of the window, each pinion being engaged by two racks (19) one of which is mounted on element 15 and the other on element 16.

Abstract: 345,614. Feeding webs. JOACHIMCZYK, M., 33, Knesebeckstrasse, Charlottenburg, Berlin. Dec. 11, 1929, No. 38045. [Class 100 (i).] In a machine for cutting out and gumming envelope &c. blanks, webs 2, 2a are drawn from reels 1, 1a through printing-devices 4 and a tension controller 8 to gapped adjustable feed rolls 11. The tension controller 8 carries a roller 7 for each web and is oscillated to take up the slack in the web by a lever 22. The web is fed beneath a head 42 reciprocated from a cam 13 and the waste parts, shown shaded in Fig. 5 are forced through the lower die. The cam 13 oscillates a lever 20 carrying a thin metal plate for preventing contact of the printed sheets. The blanks are fed by bands 27 to a bin 29. A roller 30 feeds the blanks through a gumming-device 32 and bands 31 convey the gummed-blanks to a bin 33. The tension controller and the press are operated from a shaft 15. In a modification the bands 27 are replaced by reciprocating dogs.
