Title: Improvements in or relating to multistable trigger arrangements
IPC: H03K3/284
Filed: 1960-09-30
Abstract: 946,245. Transistor switching circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 30, 1960 [Oct. 2, 1959], No. 33640/60. Heading H3T. A multi-state circuit comprises a control transistor 1, to which a variable control signal is applied, and a number of further transistors 2, 3, 4 cascade connected so that the emitters of each preceding transistor is directly connected to the base of the following one, the emitter of the control transistor being connected via a resistor 5 to the emitter of the last of the further transistors. In the four state circuit described, assume initially that transistor 1 is cut off and transistors 2, 3, 4 are saturated, then applying a signal to the base of transistor 1 will cause collector current to flow and will bring transistor 4 out of saturation so that its gain rises and it is rapidly switched to the cut-off state due to the feedback to transistor 1 over resistor 5. An increase in the signal applied to the base of transistor 1 will cause current to be drawn from the base of transistor 3 via resistor 11 so that that transistor will also switch to its cut-off state. A further increase will similarly switch transistor 2 via resistor 10. An auxiliary supply 15 ensures that transistor 1 has an adequate collector current. A reduction in input causes the transistors to switch back to their initial states in a similar manner.

Abstract: 788,574. Cutting and compressing wood. KUNDSEN, N. B. Nov. 29, 1955, No. 34128/55. Class 145. Round rods are cut into dowel lengths by means of rotary spaced cutting discs 9 and the ends of the dowels are simultaneously compressed to a chamfered shape by conical discs 10 on each side of the cutting discs. The rods are fed into the discs by an adjustable guard 1 eccentric to the axis of the disc or, in a modification, are pressed by a spring-loaded piston into the gap between the discs and an adjustable roller driven at a lower speed than the cutting discs. The guard or roller has a chequered surface so that the rods rotate during cutting and so that the dowels are knurled on their peripheries and, to ensure rotation of the rods, shallow grooves are provided across the cutting edges of the discs. A finger 34 removes any dowels that may have jammed between the discs.

Title: Process of producing high-grade condensation products
Inventor: BLUMER LOUIS
IPC: C08G63/127
Filed: 1932-12-06
Abstract: Resinous condensation products of polyvalent alcohols and polybasic carboxylic acids with or without the addition of monobasic acids are freed from uncombined initial materials and low molecular condensation products at an intermediate stage of the condensation by means of ethyl, methyl, butyl or propyl alcohols or mixtures thereof, the acid number of the resin being reduced.  The condensation product may be dissolved in the hot alcohol or in another solvent such as acetone or benzene and the alcohol added the first solvent being distilled off if desired. The solution, which separate into two layers, is separated, the upper layer being a dilute solution of the low molecular condensation products and the lower a concentrated solution of the high molecular condensation products.  The low molecular condensation products may be further condensed or used, for example, in conjunction with acetylcellulose.  The higher molecular condensation products may be worked up in known manner to yield artificial masses, lacquers, and paints alone or with oils, pigments, natural and artificial resins, drying oils, siccatives or nitrocellulose.  In an example, a condensation products derived from glycerin, phthalic acid and citric acid is dissolved in a little alcohol or benzene alcohol and the solution is separated into two layers by the addition of ethyl alcohol--industrial or denatured alcohol may be used.

Tivoli billiards and the like. - Mechanism actuated by the weight of a coin to move a figure into view, or to operate the grating of an animated photograph of the changing-expression kind, is regulated in its action bv a float in a liquid dash-pot. The coin may be projected by a spring lever into one of several coin buckets, each of which actuates one of the mechanisms. Fig. 1 is a broken front elevation of a machine having three mechanisms with cornesponding coin shoots A, into one of which the coin is projected from a " mortar " B by a spring lever H, I. The end mechanisms are arranged to move figures E into view at windows W, and the centre one operates an animated photograph at D. The coin bucket K of each mechanism is carried by one arm L of a U-shaped lever L, O, shown in plan in Fig. 3, which is pivoted to a fixed frame M and the arm 0 of which is bent. as shown, to extend into the tank P of the dash-pot, wherein it is connected to a float Q, the buoyancy of which is just overcome by the weight of a coin in the bucket. The coin is retained in the bucket by a fixed guide N until the lever L has moved far enough to expose the figure E, which is carried by an arm T moved by the lever, or, in the case of the animated photograph, until the pendant rod R carrying the movable grating of the device has been displaced by a pin S on the lever L. The coin then escapes through the open end of the bucket, and the float slowly rises again and re-sets the apparatus.

[Also in Division F4] In a sealable casing consisting of a support member 4, e.g. of sheet metal, and a transparent cover member 5 and enclosing one or more fluorescent discharge lamps 1, 2, a duct 6 extends through but is sealed from the interior of the enclosure and has open ends, one of which in use is higher than the other, a thermal conduction path of solid material being provided between the interior of the duct and a selected portion of the lamp envelope to convey heat from the envelope to the interior of the duct. The cooling reduces the mercury vapour pressure inside the tube to the optimum value for operation. The duct may be of metal, e.g. copper or aluminium, or of plastics material. In the latter case a metallic element in contact with the envelope may project into the duct. The conduction path may consist of resilient metal clips supporting the lamp at the selected point or points, the clips being carried by a collar 11 forming a thickened part of the wall of the  duct. Alternatively, when the duct 6 is of metal its outer surface may be in direct contact with the lamp.

In a multipart wheel rim 1 for tubeless tyres and comprising a detachable bead-seating ring 5 retained on the rim base 2 by a split locking ring 4 engaged in a gutter edge 3 of the rim base, creep of the ring 5 on the rim base 2 is prevented by a driving lug 10 secured on the locking ring 4 to engage in slots 12 and 14 in the rim base 2 and seating ring 5 respectively, the driving lug 10 being secured against circumferential displacement on the locking ring 4 by being crimped on to opposed surfaces of the ring 4 so that the engaging surfaces of the lug 10 and ring 4 are deformed circumferentially to an arc having a radius of curvature greater than that of the remainder of the locking ring 4. As shown, the rim comprises a separate beadretaining flange ring 6 which abuts an end flange 7 of the seating ring 5, and a sealing gasket 8 seated in a groove 9 in the rim base 2 provides an air-tight seal with the seating ring 5. The driving lug 10 is shaped as shown in Fig. 3 with a C-shaped opening having flat surfaces which initially loosely embrace the locking ring 4 as shown in Fig. 4. The crimping of the lug 10 is effected between a pair of dies under sufficient pressure to cause the lug opening to assume the slightly arcuate form to which the gripped portion of the looking ring 4 is simultaneously deformed as shown in Fig. 5. Any deformation of the ring 4 adjacent the lug 10 is subsequently removed.

[Class 17 (ii).] Permanent imitation creases are formed on indiarubber boots a by subjecting the article whilst on a former b and in a plastic condition to a pushing action near where the creases g are to be formed whereby one part is slidden towards another. Creases g may be formed above the ankle or instep by causing the upper leg portion to slide on the former. The top of the leg may then be secured by a strap h and, after adjustment of the creases, the boot is vulcanised. Owing to the creases, the diameter of the lower leg portion may be made greater than usual to give a wider passage for the foot without the boot appearing heavy.
