Title: Improvements in and relating to multi-wall paper bags
IPC: B65D30/24
Filed: 1929-08-14
Abstract: 338,170. Rawlins, J. D., and Paper Sacks, Ltd. Aug. 14, 1929. Paper bags.-A multi-ply bag having a valve opening in one corner is provided with a valve-forming extension comprising an inserted strip of material extending down to the lower end of the bag. A singleply strip of material 14 is folded to fit snugly the gusset 11 of a bag, its lower end reaching to the bottom of the bag and its upper end extending above the top edge thereof. The value is formed in the usual manner and the strip secured by the sewing at the top and bottom of the bag. An insertion is used at each side of the bag, and the flaps of the valves so formed overlap about the longitudinal axis of the bag, one valve serving for filling the bag and the other as an air vent.

Abstract: 984, 147. Electronic counters. C.I.T. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. June 24, 1963 [June 28, 1962], No. 25105/63. Heading G4A. A reversible binary-coded decimal counter has each stage controlled by inhibiting gates. Impulses to be counted are applied to input terminals E 0 , E 1 , according to whether addition or subtraction is required as terminal U 1  or U 2  is marked. Each stage except the second has four inhibiting gates such as VN1-VN which receive inputs from the corresponding side 0,1 of the associated stage such as A. Only one of the four gates is not inhibited and passes a pulse. The counter operates in binary fashion except that stage B has five inhibiting gates, three of which VN7-VN9 are conrolled by outputs from S 0 D, S 1 D, S 0 C, respectively.

Title: Avalanche photodetector demodulation
IPC: H04B10/07
Filed: 1978-05-31
Abstract: In order to have a low-frequency monitoring or operating channel in the case of an optical transmission link, amplitude modulation can be superimposed on the digitally modulated optical signal. A photodetector diode with avalanche breakdown (APD) is biased by a constant-current source (Icon) for the purpose of demodulation, which source has a high impedance for the high frequencies of normal digital transmission and is decoupled. The superimposed amplitude modulation is obtained as changes in biasing which are produced by the necessary variations in the gain of the photodetector. <IMAGE>

Abstract: 517,254. Moulding building &c. blocks. TAYLOR, A. B. Sept. 1, 1938, No. 25616. [Class 87 (ii)] Composite blocks are produced by placing stones in contact with a rigid surface in a frame 1 containing stopping material 4 which will flow into the interstices between the lower parts of the stones, subsequently placing a mould 2 above the frame, pouring in cementitious material to embed the stones, and then when the cementitious material has set, separating the mould and frame from the block and removing the stopping material from the interstices. The frame has sides of wedge section and the mould is shaped to fit over the frame. The frame may, as shown, have a perforated bottom 6 and may stand on feet 7 in a tray 3. Alternatively, the frame may have a solid bottom or it may be-bottomless in which case the stones 5 rest on the tray 3.

In particular, Fig. 4, if the loop controller receives a write request frame from a particular adapter, it responds by replacing that frame with a data filled frame addressed to that adapter, or if it receives a frame full of data from an adapter, it stores that data and replaces the frame with an empty, unassigned one. Each frame comprises bit, and frame synchronizing bits, address bits, and a numer of 8-bit bytes, available for transmission of data, commands, or status in response to such commands; together with further bits, corresponding to a cyclical redundancy code and parity bits for error checking. Further frames are devoted to the establishment or checking of frame and bit sync. Fig. 4 shows the nature of processing and replacement for the loop controller, that for each adapter being disclosed in Fig. 5. Figs. 2 and 3 (not shown) disclose the nature of the data handling, in the loop controller 7 and adapter 19, and that in the serial converters 13, 15, 17 ... respectively. The loop passes information in bipolar differential code, Fig. 8 (not shown) using a pair of parallel paths.

Title: Improvements relating to the manufacture of electric incandescent lamps
IPC: H01J5/62
Filed: 1953-09-18
Abstract: 724,640. Capping electric lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 18; 1953 [Sept. 19, 1952], No. 25855/53. Class 39 (2). In the manufacture of electric incandescent lamps comprising a vitreous envelope and a metal base or cap attached thereto, the base having an indentation in the side-thereof leading to an aperture through which one of the leading-in wires extends, the leading-in wire is broken off by bending it sharply at a point immediately beyond that at which it emerges from the indentation and the end of the wire is soldered to the metal of the base within the indentation, so that substantially no part of the solder projects beyond the wall of the base. In the example a lamp of the miniature type adapted to be pushed bulb-foremost into a sleeve-like socket has a thin-walled cylindrical metal cap 3 of larger diameter than the bulb 2 provided with an indentation of substantially inverted V outline, with the apex of the V nearer to the end closure 21 of the cap. An aperture 26 in the deepest portion of the indentation for the passage therethrough of the leading-in wire 11 may be produced when forming the indentation by means of a punch and die and, by tensioning the wire upwardly and then pulling it down upon the edge of the metal a reverse bent 11a is produced at which the wire is severed. The cap is heated by playing a tiny hydrogen reducing flame into the depression to ensure that a solder wire will melt when applied to the indented metal and effect a joint by a mass of solder 33 upon that part and the leading-in wire.. The tensioning and shearing operations may be effected automatically in a machine of the type described in Specification 247,923, [Class 39 (ii)], by providing a pair of pivotable spring-loaded jaws 31 at one of the work stations of the machine.

Abstract: 320,496. Dehn, F. B., (Producto Machine Co.). Sept. 13, 1928. Nuts are castellated by milling-machines of the type provided with a turret work-table having special cutter-slide, cutter-spindle drive, and turret indexing arrangements. A special spindle head carrying two geared spindles 54a, 54b, Fig. 8, is employed one spindle carrying two cutters and the other one cutter, the cutters acting on work at three adjacent stations of a six station turret. The detailed construction of the machine is described with reference to a modification having a spindle head and turret portion for other work, the pinion 124 on the end of the shaft 90 being replaced by a worm 91 driving the single spindle then employed. This spindle has a main bearing 72 and outboard bearing 71 at each end. One bearing 71 is carried by a bracket 74 and the other by an auxiliary slide 52, Fig. 2, connected by a cross bar to a main slide 68 carrying the bearing 72. These slides are vertically movable in a horizontal slide 55 under the control of springs 63 and a lever 51 operated by a cam on a shaft 43. The slide 55 is fed by a second cam on the shaft acting in conjunction with a chain 59, Fig. 2, and spring 62. The machine is driven by a motor 16 through a shaft 18 having two chain wheels located between a pair of gear box casings 13 arranged in the frame, one gear box controlling the spindle drive and the other the various feeds, both boxes containing change gearing. The cutter spindle drive passes by a chain 76 and clutch 81, controlled by rock shaft 83 and lever 84, through gearing 85 to a stub shaft 86, universal joint 89, and telescopic shaft 88, 90 to the worm gearing 91. The feed drive passes by a chain 34 and clutch 36a to worm gearing 42. The turret base 98 is adjustable towards and from the cutter spindle by bolts 99 and carries a circular table 96 provided with a notched ring 117, Fig. 5. Various work holding fixtures are secured to the table 96. The index bolt 115 is forced home by a cam acting through a lever and rod 120, and is withdrawn by a spring 118. Indexing is effected by a spring pawl 104 carried by an arm rocked by a toothed sector 109 and spring controlled rack bar 110 coupled at 114 to a cam controlled rod 113. A cam 108 engages a pin on the pawl and trips the pawl from the notch at the completion of the indexing. The leg 9 of the frame is formed as an oil reservoir and is fitted with a grating 10<a> on which chips are collected for removal through a door 93.
