Title: Improvements in heel seat lasting machine
IPC: A43D21/12
Filed: 1936-04-23
Abstract: 474,233. Boot - making machines. BATA ACKCIOVA SPOLECNOST. April 23, 1936, No. 11576. Convention date, April 23, 1935. [Class 17 (i)] Lasting.-A heel-seat lasting-machine comprises heel end wipers, a pair of side wipers located forwardly of the heel end wipers and adapted to move inwardly to wipe over the margin of the upper and then to swing toewardly to stretch the upper, and a resilient heel band adapted to be pressed against the upper on the last as a result of the movements of the end and side wipers. The end wiper mechanism comprises a wiper 21 carried by the usual slide, not shown, and wipers 19 adapted to move in curved guides in the slide and operated from the driven shaft 7 through racks 9, levers 12, adjustable links 15, 16 and levers 22. The side wipers 49 are carried by bars 47 which are slidable in guide members 52, Fig. 2. The latter are pivoted to the machine frame at the rear end by an adjustable pivot 53 and held resiliently at the forward end by springs 56. Each bar 47 receives its wiping movements from the shaft 7 through a yielding transmission comprising a rod 34 and a block 37 having a rack meshing with a pinion on a shaft 41 to which the bar 47 is connected by a pin-and-slot connection 46, 45. The rod 34, which slides in a tubular screw 32 adjustable in a sleeve 29, is raised by a spring 36. The sleeve 29 is reciprocated by the shaft 7 through gearing 26, 27 and effects the operative stroke of the block 37 and bar 47 through a spring 40. In the operation of the machine, the wipers 49 are moved in to lay the margin of the upper over the insole, and are then engaged by abutments 51 on the end wipers 19 so that they are swung toewardly to stretch the upper, the springs 56 permitting this movement. The resilient heel band 59, Fig. 5, is carried by supports 60, 68, 72. The supports 60 are pivoted to levers 62 pivoted upon a slide 64 and pressed inwardly by spring plungers 65. The supports 68 and 72 are pivoted respectively to the levers 22 at 24 and to the side wiper bars 47 at 48, so that they partake of the movements of these members. The upper, after lasting, is secured by tacks driven through apertures 87 in the wipers by tacking mechanisms carried by the wiper supports. Each side tacker comprises a plunger having a pivotal mounting for the driver and a spring buffer.

Title: Logarithmic-mode separately quenched superrengenerative amplifier
IPC: H03D11/00
Filed: 1949-05-03
Abstract: 663,473. Super-regenerative circuits; frequency modulation. HAZELTINE CORPORATION. May 3, 1949 [May 22, 1948], No. 11805/49. Class 40 (v). A saturation mode super-regenerative receiver has its saturation level determined by a limiter connected across the oscillatory circuit and which comprises a rectifier in series with a selfbiassing circuit. This prevents the valve being driven into grid current and thus avoids the necessity of providing a low impedance quench source or a special short time constant grid circuit to prevent grid blocking. As shown, the receiver comprises an oscillatory circuit 11, 13, 14 connected to a valve 10 to form a Colpitts oscillator, and a quench source 20 feeding a quench wave A to the grid of the valve. A diode 22 is connected across the oscillatory circuit in series with a self-biassing circuit 23, 24 which maintains the diode non- conducting until the desired saturation level is reached. The mean duration of the saturation level is maintained constant by a bias derived either from a separate diode 27 coupled by a coil 30 to the oscillatory circuit or from the selfbiassing circuit 23, 24, Fig. 2 (not shown). In an alternative circuit (Fig. 3), the superregenerative valve acts also as a frequency changer, the circuit being oscillatory at the intermediate frequency. In addition the rectifier is replaced by the control grid-cathode path of a pentagrid valve 67, the self-biassing circuit 68, 69 being connected between the oscillatory circuit and earth and supplying through resistor 63 the bias which maintains the saturation interval constant. The pentagrid valve also acts as a demodulator, the modulation being extracted from the second grid and the anode. Frequency modulation may be detected either by detuning the oscillatory circuit or by providing a detector which is sensitive to the phase variations of oscillations. In the latter case undesired amplitude modulation may be removed by making the time constant of the bias circuit which maintains the saturation level interval constant (e.g. circuits 23, 24; 28, 29; or 68, 69) short enough to follow the modulation. Specification 648,920 is referred to.

Title: Improvements in prepayment mechanism for gas, electricity and like meters
IPC: G07F15/02
Filed: 1939-04-20
Abstract: 527,748. Coin-freed meters. WILSON GAS METERS, Ltd., G., WILSON, J. H., and POOLE, D. C. E. April 20, 1939, No. 11863. [Class 27] In prepayment mechanism for gas or electric meters, of the kind in which the tariff is charged automatically when a certain quantity has been consumed, a certain proportion of the coins inserted are returned to the customer after the predetermined quantity has been consumed. This is effected by the positioning of a pivoted shoot 12 to deliver to the customer or the till in alternative positions. Each coin inserted, rotates a star wheel on the shaft 17 one tooth on its passage through the apparatus. When the wheels 23 and 41 are in gear, the rotation of the star-wheel is transmitted through the reduction gearing to the toothed wheel 38 which operates the pin 39 on the shoot 12, thus positioning the latter to return every nth coin. Normally the wheels 23, 41 are held out of engagement by the holding of the pivoted frame 19 on which 23 is carried. A projection 34 on an arm of the frame engages a collar 28 on a shaft 30 which is rotated by the meter as consumption proceeds. Eventually, the pin 34 registers with a slot in the collar and allows a spring to swing the frame and engage the gears. Pre-setting of the knurled head on the shaft 30, which carries a pointer 31 moving over a fixed scale, varies the point at which the change-over in tariff occurs.

Title: Process for the manufacture of reinforced glass
IPC: B32B17/10
Filed: 1938-04-20
Abstract: 511,996. Polyvinyl acetal resins. SOC. DES USINES CHIMIQUES RHONE-POULENC. April 20, 1938, No. 11869. Convention date, May 4, 1937. [Class 2 (iii)] [Also in Group VIII] A process for the manufacture of reinforced glass, the reinforcement of which is constituted by a polyvinyl resin of the acetal or partial ester type, consists in softening a sheet of the resin by immersion in a plastifying bath, none of the constituents of which has a boiling point below 175‹ C:, placing this sheet between two sheets of glass below the surface of the bath, pressing the assemblage gently and then heating under pressure. The acetal resin is the combination of polyvinyl alcohol and aldehyde, and the partial ester type resin is a polyvinyl ester saponified until it can swell in water while still being completely soluble in organic solvents such as the lower alcohols and ketones. Examples of liquids which can be used as the plastifying bath, alone or in mixture, are benzyl alcohol, the monoacetate of ethylene glycol, the formal of glycerine, and the lactones of y-hydroxyacids such as y-hydroxybutyric acid or gamma-hydroxy-n-valeric acid. To improve the adhesion of the resin to the glass, silicic or boric esters may be added to the plastifying bath, as is shown in the case of intermediate layers containing a cellulose derivative in Specification 428,548. In examples (1) 18 parts of a polyvinyl acetal obtained by the reaction of 1 mol. of formaldehyde and 2 mols. of polyvinyl alcohol of average viscosity, is dissolved in 100 parts of a mixture of 80 parts of methylene chloride and 20 parts of absolute alcohol. The solution is cast to give a film of .5mm. thickness after evaporation of the solvent. A piece of the film is immersed in a bath of benzyl alcohol at 18‹ C. for 20 secs. and assembled between two sheets of polished glass of 3 mm. thickness, and the assemblage is passed between pressing rollers covered with rubber, and heated at 115‹ C. in an autoclave under a pressure of 3 kgs. per sq. cm. for 35 minutes. Cooling also is effected under pressure. (2) 50 parts of a polyvinyl acetate of low viscosity are dissolved in 100 parts methyl alcohol. Saponification is effected by heating in the presence of small quantities of sulphuric acid until a product is obtained which can be swollen by water but is still soluble in methyl alcohol. The acid is neutralized and the solution is cast to obtain a film .8 mm. thick. The film is softened and assembled between two thin sheets of glass under a bath composed of 20 parts of glycol, 75 parts of glycerine formal and 5 parts of methyl silicate. The assemblage is pressed between rollers, heated in an autoclave at 135‹ C. under 3 kgs. pressure and cooled under pressure. Other examples are given. Specifications 316,955, [Class 20 (iii)], and 389,106, [Group VIII], also are referred to.

Abstract: 692,698. Making glass fibres. SCHULLER, W. Aug. 4, 1950 [May 6, 1949], No. 12199/49. Class 56. Glass or like fibres 2 are removed from a drawing-drum 3 by a scraper 5, the free edge of which is at a distance of about one-quarter of the drum diameter from the pivot 7, this distance being sufficiently large to minimise the increase in the angle of incidence with the drum as the scraper wears. To prevent the scraper from meeting the drum too steeply as wear continues, a support 11 is provided which eventually rests upon the drum and necessitates replacement of the scraper. The scraper blade is replaceably carried by a resilient plate 9, being clamped between the support 11 and a strip 12. The fibres, removed from the drum, enter a device 8 which changes their direction of movement. The scraper is kept against the drum by a weight 10 adjustable along a member 13, and is raised when necessary by a lever 14. The apron 4 extends over at least one half of the circumference of the drum, is nearest to the drum at the entrance end a, is most widely separated from the drum at b, and again approaches the drum at c. Thus only slight air disturbance occurs at the entrance to and exit from the apron, and the fibres are passed to the device 8 without twist or entanglement.

Abstract: 908,527. Loose covers for books. BLUNT & SONS Ltd., G. April 6, 1961 [April 6, 1960; May 25, 1960], Nos. 12261/60 and 18447/60. Class 16. A book jacket is made from two sheets or plies 1, 2 secured together along a line or band 5 at or adjacent one margin. The inner ply 1 is paper, and the outer ply 2 is a transparent foil of thermoplastic material. The ply 1, Fig. 1, is wider than the ply 2 so that it extends beyond the edges 3 and 4 of the ply 2, and a duct cover 6 is placed between the plies. One edge of the jacket is folded along the line 13, and the other edge along the line 14 to suit the height of the book, and the jacket is then applied to the book by folding the sides of the jacket about the cover boards. Since the two plies 1, 2 are free to shift relatively to one another, the inner ply 1 is not buckled during the top and bottom folding operations. In Fig. 5, the transparent outer ply 2 extends beyond the edge 16 of the paper inner ply 1 at one margin, but at the other margin the inner ply 1 extends beyond the edge 17 of the outer ply 2. The top extension of ply 2 has a line of pressure-sensitive adhesive thereon which is covered by a removal protective strip 19. When a dust cover 6 has been placed between the plies, the jacket is first folded inside about the edge 17 adjacent the joining band 5, and the opposite edge of the inner ply 1 is then folded over to suit the height of the book. The overhanging edge of the outer ply 2 is now folded over, the strip 19 removed, and the ply 2 is adhesively secured to the inner surface of the ply 1. The jacket can now be applied to the book by folding the sides of the jacket about the cover boards.

Title: Improvements in and relating to the geneva cross mechanism of turret lathes
IPC: B23Q16/02
Filed: 1933-04-27
Abstract: 405,149. Intermittent toothed gearing. SCHUTTE, A. H., 76, Rheinallee, Deutz, Cologne, Germany. April 27, 1933, No. 12312. Convention date, May 3, 1932. [Class 80 (i).] A Geneva mechanism has driving-gear for increasing the angular velocity of the actuating arm while it engages the slot, and correspondingly decreasing the velocity of the arm during the idle part of its revolution. In the form shown in Fig. 1, a pair of toothed wheels 2, 8, the former fixed to the driving-shaft 1, have gear-segments of different pitch diameter joined by intermediate engaging surfaces 5, 6, 11, 12. An arm 13 fixed to the shaft 7 of the driven wheel 8 carries a roller 14 and a disc 9, which engage the Geneva cross for the stepwise rotation of a member 24. By this means the speed of the arm 13 is increased during indexing, and decreased during the idle part of its rotation, so that the arm makes a complete revolution in the same time as the driving-shaft 1. In the form shown in Fig. 2, rollers 32, 33 on the ends of an arm 31 attached to the toothed driving wheel 28 enter slots in the wheel 42, and, in co-operation with the curved portions 30, 37 on the two wheels, serve temporarily to arrest the rotation of the arm 40, so that its time of revolution equals that of the driving shaft 27.
