Title: Improvements in apparatus for preparing material for packaging
IPC: B65B61/08
Filed: 1936-10-13
Abstract: 469,218. Sawing; packeting. BURGESS, A. F. (International Cellucotton Products Co.) Oct. 13, 1936, No. 27761. [Class 145 (ii)] [Also in Group XVII] An apparatus for preparing material for packaging comprises a receptacle for holding a length of the material, for example a pile of paper strips, and a cutter adapted to traverse the receptacle to sever the material into short sections, there being a tray fitting into the receptacle below the material by which the severed sections may be simultaneously removed from it. In the apparatus shown, piles of paper strips to be cut into sections are contained in trough-like receptacles 16 secured to frame-members 17 which are moved on tracks 18 in order to carry the strips past a gang of circular sa,ws or outters 14, which pass through slots 23 in the sides of the receptacles and extend into grooves 24 in their floors, and so sever the pile into short sections. Lying in grooves in the bottom of each receptacle, so as to be clear of the saws, is a frame or tray 27, Fig. 7, having upright ends 30 to which are attached spring clamping- members 32 which secure the ends of the pile of strips. After the strips are severed the tray carrying the severed sections is lifted out of the receptacle and is transferred to a work-table 38, Fig. 8, having elongated apertures in it through which the tray falls, leaving the material, which spans the aperture, on the table. The apertures may be normally closed by pivoted counterweighted members 41.

Title: Improvements relating to hoists
IPC: B66D1/36
Filed: 1960-08-11
Abstract: 920,542. Cable drums. GARRETT CORPORATION. Aug. 11, 1960 [Aug. 14, 1959], No.27909/60. Class99(2). [Also in Group XXX] The cable drum 9 of a hoist carries a helical cable retainer 13 the gaps between the turns of which overlie the turns of the cable 12. The gaps between the retainer turns are normally sufficiently narrow to retain the cable on the drum, but they are strained apart locally in the region where the cable leaves the drum. During winding and unwinding, the cable is guided by a block 47 movable axially of the drum along a rod 4 and incorporating a guide wheel 34 whose flanges provide the means for holding the retainer turns apart. The block 47 also carries means for holding the turns of the retainer at their normal spacing outside the region immediately adjacent the guide wheel 34. In the form shown this means is a spool 48, Fig. 3, with flanges 49 spaced to register with the gaps of the retainer. In an alternative construction (not shown) two arms carried by the block 47 extend from the region of the guide wheel 34 circumferentially of the drum in opposite directions. One of these arms carries a channe section member whose flanges grip the remote edges of two adjacent retainer turns and the other arm carries a pressure shoe which is resiliently urged against the adjacent edges of these turns. The hoist shown is driven by an electric motor through gearing which includes an epicyclic gear whose planet pinions 29 engage internal ring gears 31, 33 on the fixed end cover 32 and the drum 9 respectively.

Title: Narrow band digital speech communication system
IPC: H04B1/66
Filed: 1972-06-15
Abstract: 1393743 Speech transmission system INTERNATIONAL STANDARD ELECTRIC CORP 15 June 1972 [16 June 1971] 28056/72 Heading H4R In a speech communication system the speech incoming to the transmitter is applied to a filter 3 which is continuously adjusted to remove the predictable portion of the speech signal. The residual signal at the output of the filter 3, is transmitted, e.g. by delta modulation, together with information concerning the predictable portion of the signal which has been removed by the filter. At the receiver the residual signal is passed through a filter 12 which is controlled by the transmitted information signal so as to restore the original speech. As described the incoming speech is converted to digital form in 10 bit 8 kHz sampling rate A to D converter 2 and passed through a filter 3, Fig. 2, of the transversal type in which the multipliers W1 and W2 are adjusted, to values derived in 4 by a correlation technique, so that the output from the filter has a main formant removed. The values W1 and W2, in binary form, are multiplexed with the filter output after the filter output has been converted to a delta modulation form, and after the binary values of W1 and W2 have been converted from 5 bit and 4 bit words respectively to an 8 bit composite word, and the values W1 and W2 checked and modified if they are such as would make the receiver filter unstable. The multiplexed signals are transmitted to the receiver and demultiplexed, with synchronism established by looking for an 8 bit block, representing the values W1 and W2 which never contains the barred combinations, and stepping the synch. one place if such a combination occurs in a selected 8 bit block. After demultiplexing, the excitation function is decoded in delta decoder 11 and fed to the filter 12, see also Fig. 2, the parameters of which are set by the values of W1 and W2 derived from received signal via the demultiplexer 9. The output from the filter is converted to analogue form in 13 and reproduced at 14. Coding and decoding are carried out by a special purpose computer details of the logic circuits of which are described with respect to Figs. 4 to 16 (not shown).

Title: Improvements in web tensioning devices for printing and other machines
IPC: B65H20/06
Filed: 1932-10-10
Abstract: 411,829. Feeding webs. KINGS PATENT AGENCY, Ltd., 146A, Queen Victoria Street, London.-(Schnellpressenfabrik Frankenthal Albert et Cie Akt.-Ges. ; Frankenthal, Bavaria, Germany.) Oct. 10, 1932, No. 28163. [Class 100 (i).] In a web-roll controlling device for printing and other machines in which an endless belt 10 engages the roll surface and is normally driven thereby, a slipping clutch 9 is interposed between the shaft 15 of one of the belt drums 11 and a shaft 21 which is driven from the machine at a speed slightly less than that at which the drum shaft is driven by the belt. Friction discs 27, 28 on the clutch parts are pressed together by a spring 29, the pressure of the spring, and consequently the tension of the web, being regulatable by lever mechanism 32, 31 actuated by gearing 38 from a hand wheel 37. A graduated disc 39 moving against a pointer 40 serves to indicate the adjustment necessary for web-rolls of different widths. A free-wheel device 42 incorporated in the clutch causes a positive drive of the drum 11 when the machine is being started up, to overcome the inertia of the roll. A brake B, preferably pneumatically operated, is automatically applied to the drum 11 when the machine is stopped, to prevent overrunning of the roll, but excessive retardation and consequent breaking of the web are prevented by the device 42 which prevents the drum-shaft 15 from rotating at a slower speed than the shaft 21.

Class 39(3) [Also in Group XXII] A finned sheathed electric heating element is made by placing inside a metal tube 19 a resistance wire 11 embedded in an insulating material 13, and opening integral fins 21 on the'tube by exerting radial pressure against the outside thereof. The spiral wire 11 embedded in an inorganic insulating material 13 is placed in an inner metal sheath 20 and placed inside the tube 19. A plurality of grooved rollers 15, Fig. 2 (not shown) press radially against the tube and rotate it and feed it through a guide 14. The tube and sheath are compressed together by the rollers and the tube material flows outwardly into the grooves to form helical fins; simultaneously the insulating material is compacted. Alternatively the fins may be made parallel by feeding the tube in steps. In another embodiment Fig. 1 (not shown) the inner sheath 20 is omitted and in this case the tube 19 may be compressed radially by rolling or swaging prior to forming the fins thereon.
