Title: Improvements relating to strapping machines
IPC: B65B13/20
Filed: 1939-08-04
Abstract: 534,653. Parcelling - machines. WILLCOX, T. W. J. Aug. 4, 1939, No. 22679. [Class 94 (i)] [Also in Group I] In a strapping machine the package is gripped by a shoe 22 pivoted to a cross bar 21 which is adjustably carried by reciprocating blocks 15 at its end. The blocks 15 ride on rollers 16, 17 and are actuated by connecting rods 25 slipping through swivel brackets 24 and pivoted to cranks 12 13 mounted on a rock-shaf 10. Springs 26, 28 on the rods 25 allow of the crank: 12, 13 completing their stroke after the shoe 22 has contacted with the package. The shaft 10 is rocked by a pitman 8 coupling it to a shaft 5 intermittently rotated always in the same direction, a half-turn at a time. This step-by-step rotation is effected by a clutch 4 fixed on the shaft 5 and having a spring-pressed key 30 which engages internal teeth 3 on a power-driven pinion 1. The key 30 can be kept out of engagement with these teeth by an upper and a lower retainer 32, 31. The lower retainer 31 can be turned into inoperative position either by a pedal 33 or automatically by a Bowden wire 37, 38 which may be actuated by the contact of a package with a locating stop. This allows the shaft 5 to receive a half-turn, thus bringing the shoe 22 down upon the package, the retainer then disengaging the key 30. The retainer 32 is turned into inoperative position, after the strapping and twisting processes have been completed, by a roller 47 acting on a lever 48 conected by a link 49 to the retainer, thus permitting the shaft 5 to receive another half-turn and effect raising of the shoe 22. The crank 7 stops just over the dead centre at each half-turn to lock it against reversing. The blocks 15 have each a column of holes at any of which the bar 21 may be readily held by a pin 20, in either a horizontal or a sloping position.

Title: Improvements in reinforced fabric or like sheet material
IPC: D06M17/02
Filed: 1936-08-24
Abstract: 474,696. Compound sheet materials. BRITISH CELANESE, Ltd. Aug. 24, 1936, No. 23203. Convention date, Aug. 22, 1935. [Class 140] Reinforced flexible compound sheets and articles are made by assembling a plurality of preformed flexible sheets with reinforcing members disposed betweenthem, and one or more intermediate preformed layers comprising an organic cellulose derivative and coextensive with at least one of the sheets, and pressing so that the cellulose derivative is rendered plastic to unite the sheet and hold the reinforcing members in position. The organic cellulose derivatives may be esters or ethers. The surface sheet may be felted, woven, knitted, knotted or netted from linen, silk, wool, cotton, regenerated cellulose, organic derivatives of cellulose, or paper, leather, metallic foil, artificial films or imitation leather. The back or lining layer may be the same as or different from the surface layer. Either sheet may also be a laminated material comprising a sheet of thermoplastic material. The reinforcing members may be heavy or tightly woven fabric, strip material made from cellulose derivatives or synthetic resins, or whalebone, cardboard, pressed cellulose with or without a binder, or metal such as copper, aluminium, iron, brass or steel. The thermoplastic intermediate layer may be a film or fabric made wholly or in part of yarns of an organic cellulose derivative. The fabric may be padded with a plasticizer or the yarns may contain a plasticizer. A fabric of cotton, silk or wool coated or impregnated with an organic cellulose derivative in the form of an aqueous slurry or powder may be used. A plasticizer may be present with the cellulose derivative or applied by spraying or padding. The assembly may be hot-pressed in the presence of moisture or a solvent. The assembly may be built up in a number of ways. For example, as shown in Fig. 3, a reinforcement 11 is permanently fixed to a back sheet 9 by an intermediate thermoplastic layer 12 but only held against the front sheet 8. In the modification shown in Fig. 5, strips of thermoplastic material 15 are also placed over the reinforcing member 11. As shown in Fig. 4, the stay 11 may be permanently attached to both sheets 8, 9 by wrapping it in a sheet 13 of thermoplastic material. The application of the product in making tents, leggings, trusses, braces, seats and backs of chairs, shoes, water-buckets, umbrellas, corsets and golf-bags is described. Specification 468,099 is referred to. The Specification as open to inspection under Sect. 91 comprises also the use of rubber, latex, chlorinated rubber and vinyl resins as thermoplastic material and describes coating the reinforcements only therewith. This subjectmatter does not appear in the Specification as accepted.

Title: Regulator system for a dc motor drive
IPC: H02P3/14
Filed: 1971-04-19
Abstract: 1346819 Control of D.C. motors WESTINGHOUSE ELECTRIC CORP 19 April 1971 [19 Feb 1970] 23215/71 Heading H2J [Also in Division G3] A regulator system for dynamically braking or possibly reversing a D.C. motor comprises circuitry for maintaining the armature current at zero while the field flex is reversing. The circuitry of Fig. 1 adjusts the unidirectional armature current and bidirectional field current to the valve commensurate with the speed commanded by a signal applied at terminal 24. Tacho 20 provides a feedback speed signal which is compared to the command signal and elements 42, 52 and pulse generator 68 trigger the thyristor module 16 at a rate required to give the desired armature current. Elements 74, 84, 94 and 112 constitute the field current control circuitry which pulses the thyristor module 18 at a rate which gives the required field current for the speed selected. If a command signal is given to slow down or decelerate the motor the field control circuitry operates to reverse the current to the field windings, but the armature current is still pulsed in the same direction. As a result the back e.m.f. is reversed and the motor is dynamically braked. Contacts 1CB1 and 2CR1 are controlled so that as the field flux approaches a predetermined positive value +#w (Fig. 2(d), not shown), contact 1CR1 is opened thus de-energizing the armature control circuitry and reducing the armature current to zero. As the field approaches a predetermined negative value - #w (Fig. 2(d), not shown) contact 2CR1 closes and the armature control circuit is re-energized thus re-pulsing the armature current in the same direction. The field flux reaches a maximum negative value and the thyristor module 18 is then pulsed in such a way that the direction of the field current is restored to its initial direction. The field flux then starts traversing to a positive value and as it approaches the predetermined negative value, -#w, contact 2CR1 is opened, thus de-energizing the armature control circuit and reducing the armature current to zero. As the field flux approaches the predetermined positive value +#w contact 1CR1 closes, re-energizing the armature control circuit and thus supplying current to the armature. The system then settles down to the new speed.

Title: Process for printing textile material
IPC: D06P5/12
Filed: 1960-07-04
Abstract: In the preparation of white or coloured resist effects on textile materials by printing the materials with a paste containing a resist, and in the case of coloured effects, a reducing agent and a vat dyestuff, before or after the materials have been padded with a solution of a sulphuric acid ester of a leuco vat dyestuff together with a nitrite, and finally developing the vat dyestuff from the leuco ester in the unprinted parts by treatment with hot dilute sulphuric acid, improved results are obtained by employing as the resist a reaction product of an aldehyde or ketone with an alkali metal hydrosulphite and a compound containing at least one amino or imino group to which is bound directly an aromatic or heterocyclic radical or a further NH2-group or a further -NH2 group substituted by an aromatic or heterocyclic radical.  In the case of the production of white resist effects, the components of the reaction product viz.:-an aldehyde or ketone, an alkali metal hydrosulphite and the amino or imino compound, may be added to the paste instead of the reaction product itself.  Specified aldehydes or ketones are formaldehyde, acetaldehyde, benzaldehyde, furaldehyde, acetone, methylethyl ketone, cyclohexanone, acetophenone and benzophenone. Specified amino or imino compounds are hydrazine, phenylhydrazine, aniline, o- and p-phenylene diamine, p-amino-phenyl-glycine, p-methoxy-phenyl-glycine and anthranilic acid.  Examples are given.

Filed: 1951-10-09
Abstract: 721,218. Discharge apparatus. POSTMASTER GENERAL. Oct. 9, 1952 [Oct. 9, 1951], No. 23522/51. Class 39 (1) A process for exhausting an electronic valve includes the step of applying to the control grid or other selected electrode of the valve a train of pulses of high positive peak voltage and short duration. The pulses may be in the form of square waves of a few microseconds duration having a peak voltage between 100 and 1,000 volts and a repetition rate of 50 per second; it is explained that these pulses produce a strong field near the cathode so that it is possible to age the valve by passing the maximum current through it instead of increasing the current by steps to the maximum as in known methods, and the ageing process may last about a minute instead of about an hour with known methods. The pulses are preferably applied to the control grid, but may be applied to another electrode of a multielectrode valve.
