Title: Improvements in or relating to telephone or like signalling systems
IPC: H04B3/20
Filed: 1931-08-06
Abstract: 387,391. Two-way transmission. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Dudley, H. W.; 123, South Oraton Parkway, East Orange, New Jersey, U.S.A.) Aug. 6, 1931, No. 22286. Convention date, Aug. 8, 1930. Addition to 362,858. [Class 40 (iv).] In a system comprising four-wire sections, e.g. London-Ireland, Newfoundland-New York, and a long intervening two-wire submarine cable section, speech arriving from the land line LL, Fig. 1 (assuming nothing is arriving from the cable terminal), causes 16<1> to connect it to the transmitting part of the four-wire circuit and to transmit thereover with or just ahead of the speech a control current outside the speech frequencies used (say 3100 cycles). At the cable terminal, Fig. 2, the control and speech currents are separated by the circuit 76 and the filter 31, and the former currents acting on amplifier-rectifiers 58, 59, control the grid potentials of the amplifiers so as to render effective those in the transmitting path and to disable those in the receiving path, and energize relays 39, 45 to switch the cable from the receiving to the transmitting branch and to transmit control currents from the generator 61 over the cable. When speech from the land side ceases, conditions for receiving from the cable are restored. Speech and control currents arriving from the cable are separated by filters 53, 70 and the latter currents acting on amplifierrectifiers cause the transmission of control currents from the generator 62 and by acting on the grid circuit of the amplifier 57 remove the power of the transmitting branch to appropriate the cable and disable the receiving branch. At the London end the control currents are separated out and energize relay 20 which prevents the land line from being associated with the transmitting path and relay 21 which reduces the loss normally imposed by a network 81 provided to ensure that currents arriving from the receiving path and finding their way into the transmission path shall be unable to operate the combination 17, 161 which is extremely sensitive. Automatic volume control is provided by the circuit 66 the impedance of which varies with the strength of the tone signal. In a modified arrangement, Fig. 3 (not shown), the volume controller is operated by a separate amplifier-rectifier and precedes the switching-controlling amplifier-rectifier. Series condensers 36, 47 are provided in addition to pre-distorting and attenuation equalizing networks 32, 50, 51 for discriminating against lowfrequency interference and promoting the decay of relaxation currents. Separate sending and receiving sea-earths are provided. Separately earthed shields are provided for the receiving transformer, a point on which is permanently connected to the sending sea-earth to avoid clicks from induced voltages. The secondary of the sending transformer is shunted by a neon tube. In a modification, Fig. 4 (not shown), the control currents are transmitted through the cable terminal repeater.

Title: Process for transforming alicyclic ketoximes into the corres ponding lactams
IPC: H03K17/95
Filed: 1972-05-12
Abstract: 1342550 Lactam preparation STAMICARBONNV 12 May 1972 [15 May 1971] 22430/72 Heading C2C The Beckmann re-arrangement of alicyclic ketoximes into the corresponding lactams is effected by dissolving the oxime in dimethyl sulphoxide and contacting the solution (e.g. at >750‹C.) with an acid solid catalyst (e.g. a strongly acid cation exchange resin in the H<SP>+</SP> form or boron oxide). The reaction may be carried out in a continuous manner by passing a solution of the oxime in dimethyl sulphoxide through a column of a dried, strongly acid cation exchanger in the H<SP>+</SP> form, the DMSO having been dried by passage through a column filled with a molecular sieve. The cation exchanger may be periodically regenerated by treatment with 100% by weight H 2 SO 4 , oleum or a solution of H 2 SO 4  in DMSO and then washing with DMSO. The examples prepare caprolactam and laurolactam from corresponding ketoximes.

Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1930-07-28
Abstract: 356,405. Slicing machines. FITZPATRICK, H. D., 94, Hope Street, Glasgow.-(Naamlooze Vennootschap Maatschappijtot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen; 33, Boezemsingel, Rotterdam, Holland.) July 28,1930, No. 22637. [Class 28 (ii).] A slicing machine has a stacking mechanism including a rotating conveyer which is brought momentarily to rest at each slice-discharging operation of the fly. As shown, the conveyer comprises vertical spiked members 6 depending from a quadrant 8 having an integral boss 9 loose upon the shaft 10 which is constantly rotated by chain and other gearing connecting it to the handwheel shaft. An arm 32 is secured to the boss 9 and is connected to a collar 31 keyed to the shaft 10 by a compression spring device 30 so that when a stop 41 on the fly contacts with the arm 32, the conveyer is temporarily stopped. Normally the arm 32 is pressed against a leather pad 34 on an arm 33 projecting from the collar 31, and when the conveyer is released by the discharge stroke of the fly, the arm 32 rapidly reassumes this position. The fly is raised by a roller 37 which engages a cam 35 on the shaft 10, and when the roller reaches the steep drop 35b a compression-spring device 36 throws the fly forward. The fall of the fly is checked by a brake block 50 connected to the fly by a link 52. The invention is applicable to machines in which the fly rotates with the conveyer. Specification 250,402, [Class 28 (ii), Kitchen and like appliances &c.], is referred to.
Patent GB-226759-A (GB)
Abstract: 226,759. Cristiani, A. W. Sept. 25, 1923. Cleaning and trimming moulded articles.-In a machine for smoothing the edges of tiles, of the kind in which the tiles are conveyed between guiding members 13, 14, means are provided to turn the tiles completely so as to present, successively, angularly disposed edges to the abrading device, the arrangement being such that one corner of the tile is held against movement by the conveyer 3 until, by the action of the latter on the remaining portion of the tile, the desired turning movement is effected. The holding means consist of an abutment 17 arranged in the path of movement of a corner of the tile, such abutment being formed on the guide 14. The guiding member 13 opposite the abutment 17 is curved as at 18, in order to allow the tile to be swung by the conveyer about the abutment as a fulcrum, and then to move in the guideway 19. The abutment 17 is formed as a curved shoulder concentric with the curve 18. The abrading means, which are provided in the guideways 15, 19, are of two kinds, non-rotatable and rotatable. The non-rotatable abrading device 20, Fig. 8, consists of a strip of sandpaper secured to a strip of fibre, which is secured at one end and has the free end maintained in contact with the tile edge. The rotary device 30, Fig. 5, consists of flexible strips 32 projecting radially from a hub 31, the direction of rotation being opposite to the direction of movement of the conveyer. A brush 570 mounted on a shaft 57 is rotated in a direction opposite to that of the tile movement. Soft idle rollers 41 are provided to engage the tops of the tiles as they pass through the abrading means 20. Specification 226,611 is referred to.

Title: Apparatus for separating and conveying sheet-like articles
Inventor: DALEN CHRISTIAAN JOHANNES VAN
IPC: B07C1/04
Filed: 1961-06-23
Abstract: 918,008. Feeding sheets. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGEN WOODIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. June 23, 1961 [June 28, 1960], No.22813/61. Class 100 (1). Apparatus for separating sheets, postal letters, or the like from a pile so that they are uniformly spaced apart on subsequent conveyer means irrespective of the length of the sheets &c., comprises a separator belt which is alternately urged into contact with the top of the pile, and away therefrom by a pressing device under the control of a space-sensing arrangement causes the pressing device to hold the belt away from the pile for a period corresponding to the length of a sheet &c. As shown, a pile 1 of sheets is constantly urged against a slotted upper plate, and the top sheet is separated when a pair of idler rollers 7 moves downwardly to press the lower runs of a pair of separated conveyer belts 2 through slots in the upper plate. A further pair of rollers 7, movable with the first pair, presses the belts 2 against a roller 4 which is normally driven through a slip-clutch in a direction opposing the motion of the sheet and belts 2, substantially as disclosed in Specification 914,292. When a single sheet has been separated, the belts 2 act on the sheet, drive the roller 4 in the opposite direction, and feed the sheet past a light beam from a photo-cell means 6; the sheet is then gripped between the belts 2 and a pair of opposed belts 9 and fed past a second light beam from a photocell means 10. The rollers 7 are raised simultaneously by electromagnetic means in circuit with the photo-cells. In operation, before the first sheet has left the roller 4, its leading edge obstructs the first light beam, and the photo-cell 6 causes the rollers 7 to be raised just as the leading edge of the sheet is gripped by the belts 2, 9. Just before the sheet leaves the first light beam, its leading edge obstructs the second light beam, and the photo-cell 10 causes the rollers 7 to be maintained in the raised position until the trailing edge of the first sheet passes it; whereupon, the rollers 7 fall and separate a second sheet from the pile. Thus each sheet is spaced from another by the distance between the roller 4 and the photo-cell 10, and the distance between the roller 4 and photo-cells 6, 10 can be adjusted to suit the length of sheets to be separated. Where two superposed sheets are separated from the pile 1, the belts 2 act to forward the top one, and the roller 4 returns the bottom one to the pile, since the friction between two sheets is not sufficient to reverse the rotation of roller 4. A small roller 5, on a lever 11 pivoted at 12, is urged by a spring 13 against the roller 4 in the space between the belts 2, and any sheets which leave the pile, during the period in which the rollers 7 are raised, are returned by these rollers to the pile.

Abstract: 534,532. Blasting detonators. CENTRAL MINING & INVESTMENT CORPORATION, Ltd., and WOODWORTH, L. B. Aug. 9, 1939. No. 22995. Convention date, Aug. 19, 1938. [Class 9 (i)]  An electric blasting detonator, designed to be substantially unaffected by stray electrical currents, comprises a heating resistance and means adapted to be activated by the heat of the resistance so as to cause detonation of the explosive, such activation occupying a period of time substantially longer than the probable duration of any likely adventitious electrical condition. A resistance 9 is embedded in a cylindrical mass 10 comprising a material such as the oxide of thorium, cerium, and other metals of the some class, which are electrically non- conductive when cold but when hot become sufficiently conductive to pass a current whicn raises the mass 10 to incandescence and so ignites the detonating mass. The Specification as open to inspection under Sect. 91 describes a modification wherein the cylinder 10 comprises a non-conductor such as magnesite with an external layer of magnesium powder, which ignites when the magnesite has been heated sufficiently. This subject-matter does not appear in the Specification as accepted.
