IPC: A43D9/00
Abstract: 584,905. Lasting-machines. KAMBORIAN, J. S. Feb. 6, 1945, No. 2978. Convention date, March 24, 1944. [Class 17 (i)] A machine for lasting a shoe consisting of a closed upper and a flexible insole by pulling it on to a last, comprises a slide bearing rubber friction pads which move from toe to heel of the last and wipe the shoe on to it. Two of the pads engage opposite sides of the upper and one pad engages the insole. When the operation is complete the pads are moved apart and are returned to the starting position. Near the rear end of a base 2 is arranged a pedestal 3 comprising an upwardly extending post 4 which carries a pin 6 which supports the last. A slide 13 capable of moving from front to rear of the base 2 between parallel guide members 11 and 12 is actuated by a spring 16 tending to draw it forward and a cable 15 passing over a pulley 9 and connected to a treadle to draw it to the rear. Mounted on the slide 13 is a support 20 which is free to swivel and is provided with pairs of upstanding lugs 21 which receive the opposite ends of hinge pins 22 and 22a which support wing members 23 and 23a. On the inner faces of the wing members there are mounted upper pulling elements 24 and 24a made of crepe rubber. The wing elements 23 and 23a are urged together by springs S and S'. An upright post 26 is arranged forwardly of the support 20, having bearing openings for a shaft 27 to whose forward end there is fixed a rigid lever 28 having oppositely directed arms 27a and 27b. Links 30 and 31 are connected to the arms 27a and 27b and, on depressing the lever 28, force the wing members apart. The upper end of the post 26 carries a pivoted arm having a rearward portion 34a and a forward portion 35. The rearward portion 34a is provided with a resilient pad of crepe rubber 45 and the forward portion 35 is pivoted to a link 39 whose lower end is pivotally secured to an arm 40 fixed to the shaft 27. Hence, depressing the lever 28 also raises the resilient pad 45, which is normally held in the depressed position by a vertical spring pressing upwards against the forward portion 35.

Abstract: 1455588 Multiple glazing unit manufacture SAINT-GOBAIN INDUSTRIES 19 Dec 1973 [21 Dec 1972] 58756/73 Heading C1M Apparatus for making multiple glazing units comprising at least two transparent glass sheets separated by a strip of plastics material at their peripheries comprises a first longitudinal transporter 8, 10, 11 such as endless belts C and rollers G, to transport successive glass sheets V to an assembly station M; a second longitudinal transporter 13 to carry the sheets past an extrusion station N at which the strip of plastics material is applied to the upper surfaces of the sheets; a first transverse transporter 12 such as a pivotable fork connecting the first and second longitudinal transporters 11, 13 and arranged to remove some of the sheets from the first to the second transporter upstream of the extrusion station N; a second transverse transporter 15 connecting the first and second longitudinal transporters 11, 13 and arranged to remove sheets from the second transporter 13 downstream of the extrusion device N and transport them to a first tilting device 16 arranged to invert them through 180 degrees before depositing them on the upper surface of another sheet at the assembly station M; a third longitudinal transporter 18 to transport the assembly of glass sheets from the assembly station M to a finishing station S and automatic means, such as angled rollers 91 and edge rolls 92 for positioning the sheets V on the longitudinal transporters and the first tilting device. The inverted sheet from tilting device 16 is deposited on a sheet having no plastics edge strip which is positioned on transporter 11 over a second tilting device 17 which raises the assembled sheets through just over 90 degrees to be on edge on rollers 181 and supported on transporter 18. The assembled sheets are heated by a radiant heating panel 19 and passed between pressing rollers 20 to form the seal. The sheet then continues to station S where an elastomeric silicone is injected into the joint (e.g. using the injection of Specification 1,418,565) and applies the adhesive ribbon. For forming a tripple pane two sheets carrying the plastics strip are attached one on either side of a plain sheet by the apparatus described in connection with Fig. 4 (not shown).

The flow of cleaned ballast from screen 10 to the conveyers 23 and chute 21 is controlled by a flap 29. If there is too little cleaned ballast for zone A or for spacer B the flap 24 and/or a rear section 28 of the container 22 is opened to release stored ballast. If there is too much cleaned ballast the excesss ballast on the conveyers 23 is deflected into the rear compartment 26 by flaps 30. Dust &c waste from the screen 10 is removed forwardly or rearwardly by conveyers 12, 11. If required the conveyer 11 may be reversed to bring fresh ballast from a following truck (not shown), a wedge 31 being lowered to deflect it on to the distributing conveyers 23.

Title: Electric circuits including semiconductor negative resistance diodes
IPC: H03B7/06
Filed: 1971-12-30
Abstract: 1380920 Semi-conductor devices WESTERN ELECTRIC CO Inc 30 Dec 1971 [31 Dec 1970] 60664/71 Heading H1K [Also in Division H3] An electrical circuit, e.g. for use as an amplifier, oscillator or voltage limiter, includes a semi-conductor diode containing two rectifying barriers, at least one of which is a Schottky contact. The other rectifying barrier may be another Schottky contact or a P-N junction. The first-mentioned Schottky contact is forward biased with a voltage which is less than the avalanche breakdown voltage and which at least intermittently exceeds the flat-band voltage (i.e. the voltage across the diode at which the conduction and valence band edges flatten at the reverse-biased junction). Both the flat-band voltage and the punch-through voltage (i.e. the voltage at which the depletion regions meet) must be less than the breakdown voltage. Provided that the minority carrier barrier at the forward biased Schottky barrier is sufficiently less than half the band-gap energy substantial minority carrier injection occurs, the transit of these carriers across the fully depleted region between the rectifying barriers giving rise to a transit-time limited negative-resistance effect which does not involve breakdown. For use as an oscillator the diode is situated in a resonant circuit or cavity, and the diode parameters are selected such that the injected minority carrier transit time is approximately ¥ of the period of an r.f. applied signal superimposed on a D.C. bias. Non-uniform doping of the semi-conductor body, involving a highly conductive section adjacent the reverse biased barrier, may be used to increase diode efficiency by maintaining a high electric filed throughout the major portion of the transit region during the entire operating cycle. A suitable diode construction involves a Si body having two PtSi Schottby contacts, each provided with Cr and Au layers. For P-type Si other suitable Schottby contact metals are Cs or Mg, Pt being suitable for N-type GaAs and Au being used with N-type Ge. CdS and diamond are also referred to as semi-conductor materials. Simple oscillator, amplifier and voltage limiter circuits are described. The Specification includes a full theoretical discussion of the effect employed by the invention.
