Title: Improvements in or relating to shredding apparatus and methods of shredding fibrous material
IPC: D21B1/06
Filed: 1941-05-27
Abstract: 549,712. Grinding, crushing etc.; preparing cellulosic pulp. BRITISH CELLOPHANE, Ltd. May 27, 1941, No. 6804. Convention date, June 1, 1940. [Class 59] [Also in Group VIII] A sheet or slab 17 of alkali cellulose is fed through a pivoted guide 21 to two shredding rollers 13, 15 rotating in the same direction, the rollers being covered over their entire circumferential surfaces with teeth or spikes. The rollers may rotate at the same speed, in which case the sheet is fed at an angle as shown, so that the roller 13 engages a greater surface of the sheet than the roller 15, the sheet being thus fed into the bite. Alternatively, the roller 13 may rotate at a higher speed than the roller 15, in which case the sheet is preferably fed horizontally, the rollers being driven independently of one another and one of them being connected to a variable speed motor. The angle of feed may be varied by tilting the guide 21. An auxiliary roller 19 may rotate in the same or opposite direction from that of the rollers 13, 15, and at the same or a different speed: it may be as large or larger than the rollers 13, 15. The rollers 13, 15 may be of different dimensions. The teeth may be formed by positioning " garnett wire " (a saw-toothed band) in a spiral groove 43 or in circular grooves on the rollers and securing the band therein as by welding or soldering. Sections of two different kinds of garnett wire, 41 and 41a, are shown. A curtain 29, hanging in the hopper 27, may be shaken by means of a pivoted handle 31 to dislodge lumps of (moist) shredded alkali cellulose.

Abstract: 1,162,731. Tube couplings. ERMETO S.A. 14 Feb., 1967 [17 Feb., 1986], No. 6939/67. Heading F2G. A tube coupling comprises a coupling body B having a flared mouth M into which a sleeve S is urged by a shoulder 3 of a nut N. The sleeve S is provided with an annular cutting edge E towards its forward end and a rib R adjacent its mid-point. During the screwing of the nut N on to the body B the forward end of the sleeve S engages the mouth M to force the forward end inwardly and hence the cutting edge into the tube T. The force applied to both ends of the sleeve S causes a bulging about its mid-point but on further screwing the rib R engages the mouth M so that the mid-portion of the sleeve is then urged into the tube. In a modification (Figs. 4, 5, not shown) the rib comprises a triangular cross-section annular formation on the sleeve.

Abstract: 1,140,251. Selective signalling. HORSTMANN GEAR CO., Ltd. 19 Jan., 1966 [18 Feb., 1965], No. 7014/65. Heading G4H. Remote equipment is selected by transmitting a combination of frequencies comprising one or more "guard" frequencies and an "actuating" frequency. In one embodiment for obtaining remote meter readings, a combination of three "guard" frequencies, selected from a group of 100, selects the desired meter by means of tuned circuits and gates. A modulating signal comprising a sweep over a given frequency band is also transmitted, and this produces outputs from a series of tuned circuits in turn so as to scan a set of switches actuated by cams on the meter shaft. Other embodiments e.g. for switching on groups of appliances such as street lights or "off-peak" circuits are described in which a single "guard" frequency is transmitted together with an activating frequency modulated thereon. Transmission may be over telephone lines or over coaxial cable used for wired radio or television distribution. Some controlled devices may include radio or ultrasonic transmitters to activate other devices in the same group which have not got ready access to the main feed cable.

Abstract: 441,587. Board game apparatus. MEYER, J. F., 700, Flintridge Avenue, Pasadena, California, U.S.A. July 20, 1934, No. 7194/35. Divided out of 441,552. [Class 132 (ii)] [See also Group XVIII] In a bagatelle board, balls entering a collector opening in the playing surface are normally held therein until the end of the play, but a holding device is adapted to be released by a ball entering a predetermined scoring hole in the surface, to render the used balls in the collector opening accessible for elevation to the playing position for replay. The invention is shown as applied to the game apparatus set forth in Specification 441,552, and comprises an inclined game board 8 provided with obstacles 63 and scoring holes 15. A board 16 slidably mounted under board 8 has holes 17 corres. ponding to the holes 15, the holes 15, 17 being normally out of alignment and brought into alignment by moving the board against the action of springs 18 at the end of a play. Balls which rested in the scoring holes 15 on the board 16 then fall onto an inclined board 7, Fig. 6, and run into a trough 20 which is inclined to lead the balls to the side 2 of the casing 1, from where they are elevated one by one into a projecting shoot 13 by rocking a spring biassed. sector 21 by a plunger 26, the sector engaging under the first ball in trough 20 to one side of its centre so that the ball falls laterally into the shoot 13 when elevated. An alternative elevator mechanism comprises a casting 28, Figs. 7, 8 rigid with a shaft 29 rocked by an external handle 32 to elevate the balls 24 in the cup 30 of the casting. A coin-freed slide 34 serves to actuate the board 16 to release scoring balls, through a projection 35 thereon and has an edge 38 coacting with a slidable bar 36 which through a crank 31 slightly rotates spindle 29 thereby preventing operation of the ball elevator mechanism until the slide 34 is fully retracted. The elevator mechanism shown in Fig. 6 may be similarly interlocked with the coin-freed slide (not shown). Non - scoring balls roll down the board 8 to an aperture 102 therein and rest on a pivotal plate 105, which is rocked electromagnetically to release such balls for replay should a further ball be played into a hole 103 to close electric contacts in the magnet circuit located beneath the hole. The plate 105 is also rocked through a projection on the board 16 when the latter is moved at the end of a play so that all balls are available for replay.

Abstract: 374,159. Recording sound optically. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A., and WATKINS, S. S. A., 41, Tite Street, Chelsea, London. March 9, 1931, No. 7215. [Class 40 (ii).] To facilitate the measurement of the density of a variable width photographic sound record by a photometer or densitometer, provision is made in the recording system whereby a length of the sound track is exposed for its full width, and preferably, an adjacent length is left entirely unexposed and another length exposed to the mean position prior to modulation. This is effected by a switch and bias batteries associated with the recording amplifier circuit, or with the light valve, shutter or oscillograph, whereby the normal bias may be varied. As shown applied to an oscillograph comprising a mirror 7, Fig. 1, on a conductor 4, 5 which extends through the field of a magnet 6 and receives audio currents from a microphone 1 transmitted through an amplifier and a transformer 2, the switch 28 and batteries 15, 30 are arranged in a branch from the transformer secondary including also a variable resistance 21 and an inductance 22. To make the sensitometer record before modulated currents are applied, the switch 28 is moved to the right to open the contacts 16, 17 and cut out biassing current, this resulting in the sound track, Fig. 2, being unexposed throughout its width. When the switch is moved to mid position, the battery 15 is in circuit and one half of the record track is exposed, as shown at 24, and when the switch is moved to the left both batteries are in circuit and the whole width of the track is exposed, as shown at 31.
