Abstract: 129,501. Capstick, R., and Brooks, A. A. Aug. 22, 1918. Guns.-A figure or figures representing a soldier, bird, &c. is connected to a toy gun and is caused to move when the gun is fired. In the e arrangement shown in Fig. 1, the figure a is fixed to the lever b, pivoted on the barrel and connected by a link d to a rod e normally forced forward by a spring h. When the rod is drawn back, a catch f on its inner end engages a lever g connected to a trigger i. When the gun is fired, the figure assumes the position shown in dotted lines. An anvil j on the barrel is adapted to receive a percussion cap which is fired by a hammer a<1> on the figure striking it. In a modification, the barrel c', Fig. 2, is solid and slides in the stock, being forced outwards when the trigger is pulled by the expansion of the trigger guard o. The figure in this case is connected by a fixed link m to the stock. The trigger may be made of sheet metal and provided with a hook to engage a cross-pin on the figure.

Title: Semiconductor devices

Abstract: 1516264 Isolation in monolithic integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 5 April 1976 [30 May 1975] 13632/76 Heading HlK A semi-conductor pocket laterally isolated from similar pockets in a monolithic integrated circuit by inset oxide is formed on one surface of a semi-conductor wafer of one conductivity type by conventionally etching in the surface a recess in the form of a closed figure, thermally oxidizing the material in the recess to provide an inset oxide region, introducing impurity providing the opposite conductivity type, e.g. by diffusion or implantation into the surface bounded by the oxide region, depositing a semi-conductor layer over the whole of the one surface, forming a recess in the layer in registry with that formed in the substrate and thermally oxidizing the material in the recess to form; a further region of oxide extending down to the previously formed oxide. As described the substrate is lightly doped P-type silicon, the impurity phosphorus, arsenic or antimony and the deposited layer lightly doped N-type, and the etching steps are effected, through nitrideon-oxide masking patterned by standard photoetching techniques, preferably using hot caustic potash on 100 oriented surfaces to ensure vertical walled recesses. The processing parameters are so chosen that at the end of manufacture which includes formation of a transistor in the pocket, the sub-collector formed by redistribution of the introduced impurity does not extend as deep as the inset oxide. Formation of inversion layers beneath the oxide can be avoided by acceptor doping the base of the recess in the substrate prior to thermal oxidation.

Abstract: 290,291. Jovignot, C. May 13, 1929, [Convention date]. Capsules, applying; capsule closure.s.-Glasses, jars, &c. with, smooth peripheral walls 16 are sealed by caps made from sheet steel, tin plate, aluminium &c. having peripheral flanges 18. Each cap has a circular body portion 17 of the same diameter as the glass &c. to be sealed thereby, and the encircling flange 18 is reinforced by a series of semi-spherical protuberances 19. The free edge of the flange may be plain or inwardly or outwardly curved. In Fig. 1 the free edge is outwardly curved and the part 17 has a concentric depression adjacent the flange. In sealing a container, downward pressure is applieed by a die 22 which first results in turning the free edge upon itsalf as shown at 26, Fig. 2, and finally in the flange swinging into a horizontal position 'and causing the cap to exert a gripping force on the periphery of the container. A suitable liner or gasket 27 may be interposed between the cap and the container, and a partially severed tongue may be provided in the flange 18 to facilitate opening by tearing. In modifications the free edge of the flange may be curved inwardly and the reinforcing protuberances may be oblong, corrugated or replaced by an annular groove. In a further modification shown in Figs. 14 and 15 for use with a goblit or barrel shaped container, the part 17 has a raised portion a, an annular depression c and encircling groove d for positioning the cap. The sealing die 220 and a concentric undergrooved member 22<1>. When pressure is applied to the cap it assumes the form shown in Fig. 15, gripping the walls 16 of the container in both sides.

Filed: 1971-05-10
Abstract: 1284374 Astable multivibrator MATSUSHITA ELECTRONICS CORP 10 May 1971 14064/71 Heading H3T In an emitter-coupled astable multivibrator (Fig. 2) (e.g. for a line time base oscillator) a capacitor 11 is connected between the collector and base terminals of the transistor, to the base of which a constant potential is applied in order to reduce the switching speed of the circuit and thus the radiated electrical noise. The period of oscillation is determined by capacitor 5 and resistors 3, 4. With transistor 2 cut off, capacitor 5 charges via transistor 1 and resistor 4, the charging current maintaining the potential at the emitter of transistor 2 greater than the base potential until the capacitor 5 is fully charged when transistor 2 turns on so cutting off transistor 1. The capacitor is then discharged via resistor 3 and transistor 1 is held off by the discharging current through resistor 3 until capacitor 5 has sufficiently discharged enabling transistor 1 to turn on and recharge the capacitor 5 causing transistor 2 to be cut off. The process then repeats.

Title: Improved process of treating pile fabrics
IPC: D06Q1/06
Filed: 1937-05-22
Abstract: A pile fabric is patterned by applying light pressure locally to lay the pile and fixing with synthetic resin or a reactive aldehyde applied to the whole of the fabric.  The pressure may be produced by brushing or by means of a plate, roller or the like. The fabric may be impregnated by applying the liquid to the back thereof.  The fabric is preferably impregnated first and then patterned, or dried and again dampened before patterning, a heat treatment being applied last.  Urea-aldehyde or phenol-aldehyde type resins are suitable. Other reagents may be added to the impregnating solution, e.g. softeners, stiffeners, waterproofing agents or rubber latex.  In examples: (1) a regenerated cellulose pile fabric is impregnated with a urea - formaldehyde pre - condensate, squeezed and dried at low temperature whilst brushing; before drying is completed, the pile is pressed down locally with an engraved plate or roller, dried and heated at 170 DEG  C. for 2 mins., the pattern is fixed and the fabric rendered crease-resisting; (2) a cotton back regenerated cellulose pile fabric is treated with a solution of a urea-formaldehyde pre-condensate applied to the back of the fabric by spraying or painting; the pile is brushed locally and the fabric dried and heated; (3) a regenerated cellulose pile fabric having a silk back is impregnated with a urea-formaldehyde pre-condensate and dried with brushing; the fabric is then steamed and passed over a roller having a raised pattern whereby local areas are brought into contact with a cylindrical brush rotating in the opposite direction to the travel of the fabric, which is finally dried and heated. Other examples describe the use of a phenol-formaldehyde resin, formaldehyde alone, methyl methacrylate, and also the use of a cut-out stencil to localize an all-over brushing treatment.
