Title: Composite film wrapping
IPC: B65D65/40
Filed: 1956-02-21
Abstract: 794,858. Heat-sealable coated films. SOC. INDUSTRIELLE DE LA CELLULOSE (SIDAC) SOC. ANON. Feb. 21, 1956 [June 29, 1955], No. 5307/56. Class 140. [Also in Group XVII] A heat-sealable wrapping material comprises a flexible composite sheet having a base of regenerated cellulose, a coating consisting mainly of polyvinylidene chloride on one side and a polyethylene coating on the other side, the coatings being anchored to the base by known anchoring agents, and the wrapping being heatsealable by joining portions of the polyethylenecoated surface in the presence of heat and pressure. The preferred polyvinylidene chloride coatings are those containing low percentages of vinyl chloride or acrylonitrile. They may be applied as solutions in methyl isobutyl ketone, methyl ethyl ketone, tetrahydrofuran, cyclohexanone, isophorone, dioxane or mesityl oxide. The coating may also include a wax (paraffin wax, carnauba wax or a hydrogenated vegetable or animal oil) a high molecular weight aliphatic ketone such as stearone, or a low molecular weight polyethylene; plasticizers such as dibutyl phthalate, ethyldiglycol phthalate, methyl phthalyl, methyl glycollate; tricresyl phosphate, tricetyl phosphate, dibenzyl sebacate and other known phthalate, glycollate, phosphate and sebacate plasticisers; and non-sticking agents such as fine particle clay, silica gel and talc. If desired the coating may be applied by meltextrusion. The polyethylenes have a molecular weight between 10,000 and 40,000, and may contain waxes, polyisobutylene and other compatible resins, dyes, pigments, and fillers. The polyethylene coating is applied-by melt-extrusion. Specified anchoring agents include melamine-formaldehyde precondensates and polyethylene-imine. The wrapping material may be used for heat-sealing foodstuffs or other relatively dry materials which are affected by the presence of air. Containers formed from the wrapping material may be exhausted by vacuum after packing the food in them, or partially inflated with nitrogen after evacuation and prior to sealing. Other gaseous material inert to the material of the container and to its contents may be employed for partial inflation. In an example a sheet of regenerated cellulose in the gel state is treated with a solution of a melamineformaldehyde precondensate, dried and coated with a 90 vinylidene chloride-10 acrylonitrile copolymer in a tetrahydrofuran-toluene solvent containing fine clay and castor wax. The reverse side was then coated with molten polyethylene by extrusion coating. The sheet soformed was folded into containers which were filled with food products, air evacuated from the interior and the neck sealed by heat and pressure beyond the end of the suction tube. Specifications 650,876, 721,714 and 766,827 are referred to.

Title: Improvements in contracting or relaxing the fabric of a garment or garment part
Inventor: BIHALY LAJOS
IPC: A41B3/10
Filed: 1951-03-09
Abstract: 697,682. Shrinking fabrics. TRUBENISED (GT. BRITAIN), Ltd. April 8, 1952. [March 9, 1951] No. 5737/51. Class 42 (i). [Also in Group XXX] The fabric of a garment or garment part formed of two plies of fabric which have not been fused together (e.g. a shirt collar or sleeve) is contracted or relaxed by bending two flexible belts of substantial thickness (e.g. one inch) and thereby stretching one surface of each belt, engaging the garment between the stretched outer surfaces of the belts, and then straightening the belts while the garment remains engaged between them, whereby the fabric-engaging surfaces of the two belts are contracted and both plies of the fabric are relaxed to the same extent. The belts may be of rubber and each pass around two rollers one or both of which is driven. One pair of rollers forms a nip of less width than the combined thickness of the two belts so that the parts of the belts which are moving around these rollers towards the nip have their outer surfaces brought into engagement while they are stretched by the belt curvature. After passing through the nip the belts straighten out and travel to the other pair of rollers whereat they separate. One or more pairs of small rollers may be disposed adjacent the nip of the first pair of rollers to hold the belts in firm engagement along the first part of their straight path. According to the provisional Specification, the four belt-supporting rollers may be disposed so that the belts are pressed into engagement along a sinuous path, the two plies of the fabric being thereby relaxed in turn to equal extents.

Abstract: 709,472. Gramophones. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 20, 1950 [March 3,1949], No. 5867/49. Class 40 (2). A gramophone pick-up is provided with two reproducing styli which can be selectively employed, according to whether a normal record or a slow-speed micro-groove record is to be played, and so arranged that when the stylus for normal records is in the operative position it is disposed at a greater radial position with regard to the record compared with the position occupied by the other stylus when said other stylus is in its operative position. The pick-up is designed for use with micro-groove records having a starting diameter smaller than that of normal records, which records form the subject of Specification 709,485 and having a separate outer groove, so that if the stylus for normal records is lowered thereon, as in an automatic gramophone in which the pick-up is lowered at a fixed radial position, no damage may be done to the micro-groove record. The separate outer groove may have a warning signal recorded therein and may be terminated with an eccentric groove in order to switch off the machine. In one embodiment, Fig. 2, the pick-up 3 may have a rotatable head having styli 5, 6 on opposite faces and displaced from the axis of rotation so that when the head is rotated 180 degrees the stylus 5 comes to rest at a smaller radial position 7 on the record. In an alternative embodiment, Fig. 3, both styli are on the same face of the head and contact is made bv one or other styli by a small angular movement of the head.

IPC: A43D11/00
Filed: 1957-02-21
Abstract: A stiffener is stuck to the upper of a shoe by resin applied either to the stiffener or upper in spaced blobs, and subsequently smoothed out by the pressure applied to the stiffener and upper to consolidate them.  A hollow working head 1 is filled with resin under pressure and its lower face has openings 6 normally closed by spring urged valves 9.  Plunger 17 is attached by means of bell-crank lever 31, 34 to the piston of an air cylinder.  The lever is pivoted at 32 to a movable framework 25, 26, 24, 23 so that when the piston moves to the right, part 23 moves to the right until members 24 come up against stop 39.  Attached to members 25 are a pair of bars 41 and a frame 44 which serve, when the members 25, 26, 24, 23 reach the limit of their movement, to hold down the work W by its edges.  The plunger 17 is now vertically over the work W.  On further movement of <PICT:0850823/III/1> <PICT:0850823/III/2> the piston to the right, bell-crank lever 31, 34 rocks about its pivot 32 and plunger 17 is depressed.  When the tips of valves 9 come into contact with the work W, they are forced back against the springs 12 and resin can pass through apertures 6 to the work. Movement to the left of the piston causes the plunger to rise and valves 9 to close, and frame 44 subsequently to be withdrawn. A pressing pad for consolidating the united layers after the resin has been applied may be incorporated.

Title: Improvements in echo suppressors or other similar blocking arrangements for telephone and like transmission systems
IPC: H04B3/21
Filed: 1933-02-28
Abstract: 415,717. Wired wireless systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, and LAURENT, T., 8, Karlsviksgaten, both in Stockholm. Feb. 28, 1933, No. 6143. [Class 40 (v).] In a system employing the same channels for telephony and superaudible signalling such as carrier telegraphy, a channel is adapted to be blocked as regards telephonic currents only by a short:circuit across the output end of a filter bridged across the channel and passing the speech band. Fig. 1 shows the simplest form of the invention. A preferred arrangement shown in Fig. 3 employs a differential transformer T with two bridged filters F, F<1> which have the same impedance as regards telephonic currents, but as regards signal currents, F is of high impedance while F<1> is of low impedance. The filter F is adapted to be short-circuited at its output end by a contact S, while the filter F<1> is permanently short-circuited at its output end. The impedance characteristics of the two filters of the forms shown are illustrated in Figs. 4, 5, from which it is seen that w1 is the most suitable frequency for the signalling currents. If desired, the connections of the line l1 and the filter F and of the line l2 and the filter F<1> may be interchanged. The short-circuit across the filter F may be applied through a transformer N, Fig. 7, by means of two neon tubes g as in Specification 308,816, [Class 40 (iv)]. Since this short-circuit is not complete however, a small balancing resistance R<1> is connected across the output end of the filter F<1>. In order that reflection shall not occur at the input of the differential transformer T, the bridge connection is dimensioned so that its input impedance corresponds to the line impedance. Fig. 8 shows an arrangement for obtaining this result for both positions of the contact U, the resistances R, R<1> which terminate the filters when U is operated being equal to the characteristic impedances of the filters over the speech range. Greater attenuation for speech currents may be introduced by connecting at the output ends of the filters resistances which may be included in the end resistances.
