Title: Improvements in or relating to magazine-type recording and/or play-back apparatus
IPC: G03B17/26
Filed: 1962-11-16
Abstract: 1,027,772. Recording and playback apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 16, 1962 [Nov. 21, 1961], No. 43463/62. Heading G5R. In a magazine type recording and playback apparatus in which the magazine is adapted to be locked in position on the apparatus and is provided with a brake to prevent spill of the record carrier, a single member which is inserted through an aperture in the magazine is used both to lock the magazine and to release the brake and the aperture and braking member are relatively positioned such that the part of the braking member coacting with the inserted member cannot be reached by a straight rod or similar instrument. In one embodiment (Figs. 1 and 2), a tape magazine 12 is inserted sideways into the apparatus, the tape being normally held from slipping by the pawl and ratchet type brake 43, 45. The magazine is locked by operating the lever arrangement 23, 24 which causes the curved bar 41 to enter the magazine through the aperture 42 and lock against the surface 67. In doing this it also releases the pawl brake 43, so freeing the tape and allowing the mouse 49 to be captured and transported by the arrangement 54, 55 so as to be engaged by the take up spool 58. The lever arrangement 23 also operates a system for raising the shaft 19 to come into driving arrangement with the tape spool inside the magazine. Other embodiments described include one similar to that mentioned above but wherein the magazine is loaded from above (Fig. 3, not shown) and one where the locking and brake releasing member takes the form of a key (Fig. 4, not shown).

Title: Apparatus for carrying out the drying of tanned skins under vacuum
IPC: C14B1/26
Filed: 1961-12-05
Abstract: In apparatus for drying tanned skins under heat and vacuum, means are provided for providing preselected pressures and friction to the skins whereby a particular skin can be so treated that the contraction of its fibres during the drying process is inhibited to a predetermined extent but not prevented.  A tanned skin is dried under compression between a lower, fluid heated plate 1 and a movable upper plate 6 having a downwardly peripheral edge 7 and a layer 8 of permeable material spaced from the lower surface of the plate 6 by spacers 9 to form a chamber 10 in which a vacuum is created through a pipe 11 connected to a pump (not shown).  Facings 14 of different heights are attached to the edge 7 to achieve a predetermined specific pressure on the skin by the layer 8 and the facings allow both the vacuum conditions in the chamber 10 to be regulated independently of the degree of pressure on the skin and also the pressure to be regulated independently of the vacuum so that horizontal components of tension are avoided.  The layer 8 is of a material, e.g. sponge rubber, with a coefficient of friction which hinders but does not prevent contraction of the skin fibres.

Abstract: The cyclic formals of bis-(beta-hydroxyethyl) sulphide and of bis-)beta-hydroxyethyl) sulphone are prepared.  Thiodiglycol, paraform, benzene (solvent) and p-toluene sulphonic acid (catalyst) are heated, until an azeotropic mixture of benzene and water is distilled off.  After separation the benzene is returned, the process continued until sufficient water is removed when the benzene is distilled off leaving a viscous yellow oil which on distillation at 12 mm. Hg pressure gave the sulphide formal.  A similar procedure applied to bis-(beta-hydroxyethyl) sulphone, paraform, benzene and p-toluene sulphonic acid yields the sulphone formal.ALSO:A copolymer comprises the product of polymerizing a cyclic oligomer of formaldehyde with a heterocyclic compound of formula <FORM:1031706/C3/1> where m and n are integers of at least 2, X is -S-, -SO2-, or -S1O-, and the hydrogenations of the -CH2 groups may be substituted by alkyl, cycloalkyl or aryl groups. The heterocyclic compound may be the cyclic formal of bis-(beta-hydroxyethyl) sulphide or of bis-(beta-hydroxyethyl) sulphone.  The oligomer specified is trioxane.  The polymerization may take place in the presence of an electrophilic catalyst and not more than a very small amount of water, at 50 DEG  to 90 DEG  C. under shear.  The catalyst may be a Lewis acid, e.g. boron trifluoride or its complexes and the product may be end-capped, e.g. by treatment with carboxylic acid anhydride.

Abstract: 12,22,402. Filling bags. C. N. DONALSON. 22 Sept., 1968 [16 Oct., 1967], No. 45148/68. Heading B8C. Apparatus for filling valve type bags with a fluid material comprises: (a) an endless supporting trackway 12; (b) at least one hopper 16 mounted for movement along the trackway and depending therefrom; (c) means 33 supplying predetermined amounts of material to said hopper; (d) a downwardly and outwardlyextending discharge spout 38 adajcent the lower end of the hopper; (e) a bag support member 45 mounted below and arranged for movement with the hopper so that it supports a bag in a position with the discharge spout in its valve opening; (f) means to move said hopper and bag support member along the endless trackway 12 at a speed to permit the material to flow from said hopper to the bag before the hopper is returned to the supply means 33; and (h) a releasable bottom member mounted at the lower end of the bag support member to release a filled bag, said member being releasable by a cam mounted on the trackway which engages a cam follower mounted on a projection on the bottom member. As shown, the hopper 12 is mounted on a vertical member 43 to which are attached by bracket 17, a wheel 22 running on trackway rail 12 and rollers 24 which limit lateral movement. The hopper assembly is driven along rail 22 by a sprocket chain 29. The top of hopper 12 is closed by a sprung flap which opens under the weight of the fluid material to permit entrance thereof and to reduce dust. The spout 38 is pivoted to the hopper at 63 and comprises a hollow section with a gauze outlet on its upper end so that glue may be forced on to the inside of a bag clamped thereon by clamp 80. Below the spout is mounted a vertically adjustable bag support member 45, which is pivoted at 47 and rollers 82 engage a lower rail 81 to reduce lateral movement of the lower parts of the apparatus. The bag support member may be vibrated up and down by suitable cams; the member being locked in place at other times. The movement of the spout, operation of air supply to assist the feed to the bag and glue supply are also controlled by suitably placed cams. In operation, a bag is placed on the bag support member and over the spout and is clamped in position. A measured amount of material is transferred to the hopper as it passes under the supply means 33 and this powder passes down the spout and into the bag with the assistance of air flow from line 98 and vibration of the bag support member. Glue is then supplied to the mouth of the bag, the bag support member and spout, which are linked, are tilted to transfer them to conveyer 59 and the valve of the bag may be clamped to seal it with the glue.

A Hall effect reading head comprises two Hall generator units connected so as to provide an output which is a function of the difference between the magnetic fields detected by the units individually. Such a head may be used to read a record of alternating polarities or areas of high and low intensity, such as on the rotor of a magnetic encoder, so as to eliminate the effects of spurious magnetic fields. The head consists of two sub heads H1, H2 each comprising two Hall units A, B spaced so as to overlie similar magnetic areas on a tape R such that their individual outputs are additive, but the sub heads H1, H2 themselves overlie dissimilar areas. The units are driven by A.C. or D.C. power and are either connected as shown or back-to-back (Figs. 2-4, not shown) with the units oppositely poled. The output at terminals a, c is fed to a differential amplifier. The head assembly is manufactured by conventional deposition of semi-conductor, insulation and contact metal films on a substrate in that or the reverse order.

A vacuum switch has a pair of coaxial contact carrying electrodes 11, 13 separated by a gap 14, the inner cylindrical electrode 11 having an outwardly extended conical portion 12 providing an annular contact surface 30 at an angle to the axis of the electrodes and the outer tubular electrode 13 having an inwardly directed portion 29 arranged to abut portion 12 in the closed position. Portion 29 is slotted radially (Figs. 2, 3, not shown) to divide the contact surface. Connections are made to both electrodes below the contacts 12, 29 so that the currents flowing in the two electrodes are in opposite directions; this creates a magnetic force driving the arc upwardly along the gap 14.
