Abstract: 388,079. Collapsable packing-cases. PITCHFORD & CO., Ltd., F., Well House, Well Street, Jewin Street, London, and JAMES, W., 42, Totteridge Road, Enfield Wash, Middlesex. Nov. 17, 1932, No. 4687. [Class 18.] In a box or packing- case of the kind having opposite inset ends, diagonally creased for folding, the upper or each flange of each end member is provided with an extension to lap over and be secured to the ends of the lid or of the lid and body members of the box to form strengthening ribs facilitating the handling of the box. The body a of the box may be formed from one sheet of material as shown in Fig. 1, but is preferably made from separate wooden parts. The fibreboard rectangular end members b of the box have flanges b<1> which are secured to the inside of the box body by wire staples, and the upper flange has an extension b<2> which laps over the lid of the box, the staples then connecting the three overlapping thicknesses of material, b<1>, a, b<2>. Diagonal creases are made in the end members from the bottom corners at angles of 45 degrees so that before attachment of the lid the box may be collapsed. For deeper boxes in which the diagonal creases intersect, a hole may be provided at the point of intersection with a cut extending vertically therefrom to the edge of the extension b2, one side wall of the box being formed with a horizontal crease on a level with the hole in the end and being left unattached to the flanges of the ends above this crease. Another form of end member for a deep box is shown in Fig. 6, the hole c being formed on one crease line and the cut c<1> extending parallel to and just beneath this line to the edge of the extension b2. The folding end members may be reinforced by a wooden member d, Fig. 9, provided with flexible extensions d<1> one of which is attached to the bottom flange b of the end member the other fitting between the flange b<1> and its extension b<2>. When the box is to be collapsed the member d is folded down on to the bottom. The member b may alternatively be of fibre board with integral extensions d<1>. A lighter form of reinforcement consists of a thin strip of wood cut to the depth of the box and secured by wire stitches to the outside of the end member of the box between the diagonal creases. If desired each flange b<1> of the end members may be formed with an extension b<2>. Specification 372,853 is referred to.

Title: Improvements in electrical apparatus for the automatic control of a variable condition particularly applicable to steering systems
IPC: G05D3/16
Filed: 1940-03-13
Abstract: 576,496. Controlling apparatus by light. JANEWAY, P. W. March 13, 1940, No. 4722. Convention date, March 13, 1939. [Class 40 (iii)] [Also in Group XXXV] An electrical control system employing a relatively movable beam of light and a radiantenergy sensitive device to initiate a control action and having follow - up means to restore the quiescent condition, employs a pair of spaced radiant energy sources selectively rendered operative, whereby the follow-up action is prolonged whenever the direction of change of the controlled quantity alters. Thus, telemotor error in a steering system may be eliminated and means for giving " initial rudder " is provided. The rudder motor 16 is operated through a reversing relay 25 from the amplified output of photoelectric cells L, R when light from a source A or B falls upon either, the beam passing through a lens system 3 or 4 and over a mirror 5 and 6, and a mirror 12 carried by a compass card 13. Manually-operated means 10 may adjust the mirrors 5, 6 to vary the displacement between the beams. The cell-mounting 1 is given a follow-up movement by a Selsyn transmission 35, 37 operating a worm 19, and to extend from X to Y (Fig. 6), the movement required to bring a central cell into the beam each reversal of the motor operates a relay 26 to change the light source. The cell C operates a relay 40 to de-energize the rudder motor. The angle between the beams from the two sources and the corresponding extent of the additional follow-up is determined by adjustment of a thumb-screw 8 having left- and righthand threads controlling units 9, 10 supporting the mirrors 5, 6, which pivot at 7.

Title: Improvements in or relating to the control of feed reel brakes
IPC: B65H23/06
Filed: 1932-02-17
Abstract: 396,818. Feeding webs. HOLMES & CO., Ltd., J. H., North Drive, Hebburn-on- Tyne, and TAYLOR, H., 52, Eastlands, Newcastle-on-Tyne. Feb. 17, 1932, No. 4744. [Class 100 (i).] In a control arrangement for feed-reel brakes a solenoid is energized to give a predetermined web-tension and means are provided for automatically varying the transmission of power from the solenoid to the brake with variation in the diameter of the reel. The reel C, Figs. 1 and 2, is mounted on an axle C<1> on one of those arms B which radiate from a boss B<1> keyed to an axle A. The axle C<1> carries a brake drum D in which are mounted brake shoes D<1>, which are applied by a rod E against the action of a spring D<2>. The rod E is connected by a bell-crank lever E<1>, adjustable link E<2> and lever F to a plunger G in a solenoid G<1>. The lever F is fulcrummed about two rollers H, which are mounted on a black J, which runs, by means of a roller H<2>, in the solenoid casing. The rollers H are connected by a link J<1>, two armed lever J2, J<4>, and link K<1> to a lever K which carries a roller K<2> running on the surface of the reel, and pressed against it by a spring J<5>. Then, as the reel diminishes the fulcrum rollers H are shifted downwards and the braking of the reel diminished. A solenoid and brake is provided for each of the reels but only the one for the reel in the active position is activated. For this purpose the circuits of the solenoids are made through contacts on an insulating disc N on the axle A. A complete contact ring 0 on one side of the disc N is connected to a conducting bar L in the axle A, and the three segments of a split ring O<2> on the other side of the disc are connected to three other bars L<1>, L<2>, L<3>. The bar L is connected to one side of all the solenoids by a contact M, and the other sides of the solenoids are connected to contacts M<1>, M2, M<3> riding on bars L<1>, L<2> L3. Two contacts P, P<1> are mounted to make contact with ring 0 and one of the segments, 0<2>, respectively, and serve to supply the current to the one of the solenoids which is in active position when the reels are in the passing or changeover position the brake is " on " for the used reel and not yet " on for the new reel. A variable resistance in the main circuit deter. mines the web tension, and may have a shunt which comes on when the machine is stopped so as to increase the braking. The fulcrum rollers may also be shifted by worm gear. not described, or the invention may be applied to other forms of reel stands or holders.

Title: Improvements in the process and apparatus for continuous rectification of liquid air
IPC: F25J3/04
Filed: 1921-02-11
Abstract: 159,131. Barbet et Fils et Cie, E. Feb. 11, 1920, [Convention date]. Separating gaseous mixtures by liquefaction.- In the continuous rectification of liquid air, the cold necessary to compensate for loss by radiation &c. is obtained by operating the nitrogen compressor at a higher pressure, the cold being produced by the adiabatic expansion of the unliquefied portion of the nitrogen. The Figure shows a modification of the portion of the apparatus shown in Specification 131,321. Rectified nitrogen from the upper part of the rectifying column A, A<1> passes through exchangers V, H and a water cooler K to the compressor J, wherein it is compressed say to 4 kilograms per sq. cm. and passed back through the cooler and heat exchangers. A separators y allows the liquefied portion of the nitrogen to pass to the top of the column A, A<1>; the gaseous residue passes through a motor X or expander to a coil E immersed in the liquid oxygen at the base of the column and is liquefied, passing up through a separator e and heat exchanger R<3> to the top of the column. Specification 129,648 also is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the process is applicable to gases other than air. This subject-matter does not appear in the Specification as accepted.

IPC: G11C19/04
Filed: 1956-02-17
Abstract: 779,780. Patternmovement stepping registers. MULLARD RADIO VALVE CO., Ltd. Feb. 17, 1956, No. 5083/56. Class 106 (1). [Also in Group XXXIX] In a binary shift register in which magnetic cores A, B connected in cascade are employed as bi-stable storage devices, the respective output and input windings A3, B1 are coupled by a delay circuit which produces two half-cycles of opposite polarity and continuous waveform in response to an output winding pulse, the first of the half-cycles determining the delay time interval while the delayed pulse effective in the input winding is derived from the second halfcycle. The cores may be made from a cubic ferrite material such as Ferroxcube, the information represented by their remanent magnetic states being transferred in a direction determined by rectifiers 1 by simultaneously energizing drive windings A2, B2. In one arrangement, Fig. 2, the delay circuit includes a blocking oscillator which is triggered by a pulse from winding A3, and comprises a junction transistor T1 and a transformer with blocking windings 3, 4 and input and output windings 2, 5. This oscillator provides a growth half-cycle V1, Fig. 3, which determines the delay time interval t and a blocking half-cycle V2 from which the delayed pulse is derived. The first half-cycle is suppressed by a further transistor T2 which at this stage operates as a rectifier, while the second half-cycle is amplified by T2 and acts effectively in input winding B1. In an alternative arrangement, Fig. 4, a tuned circuit L, C is shockexcited by the pulse from winding A3 and provides the first and second half-cycles V1, V2 of opposite polarity as shown in Fig. 5. During the second half-cycle an amplified output is provided by a transistor T, the input resistance of which is arranged to critically damp the tuned circuit.
