Title: Improvements in or relating to automatic coded signal generators
IPC: H04L15/22
Filed: 1969-05-29
Abstract: 1,202,669. Selective signalling. MARCONI CO. Ltd. 29 May, 1969 [30 May, 1968], No. 27311/69. Heading G4H. A morse-code signal generator is characterized in that a shift-register 1, Fig. 3, having alternate outputs D1, D2, D3, D4, connected via an "or" gate 11 to a transmission line, and the other outputs S1 ... S4, floating, has a "one" stepped along it either at a dot rate (6 c/s.) or at a dash rate (2 c./s.) so that the "one" dwells on each output D1 ... D4 for the right amount of time in order to produce the desired sequence of dots and dashes on the transmission line. A second shift-register is arranged to advance one step after each character has been generated by the first shift-register. The connections that have to be made to determine the first character generated are as follows: each of the outputs D1 ... D4 on which a dash is required is connected, by wiring not shown, to an "or" gate 4, and the output S1 ... S4, immediately following the last element of the character is connected to the K input of an "and" gate 12. The operation is then as follows: with the second shift register 16 marking its output L1, for the first character, gates 7 and 12 are open. The first shift-register 1 is stepped at 6 c./s. by an oscillator 2, producing a sequence of dots until an output occurs on a lead D1 ... D4 connected to gate 4. This causes, via "and" gate 7 and "or" gate 10, the oscillator frequency to be reduced, temporarily, to 2 c./s. causing the production of a dash. Once the dash has been generated the oscillator reverts to its dot frequency of 6 c./s. At the end of the character a signal will pass from one of the outputs S1 ... S4, via "and" gate 12 and "or" gate 15 to reset the first shift-register 1 and to advance the second shift-register to mark its second output L2 so that the second character can be produced, this character being determined by the connections made to "or" gate 15.

In a toe lasting machine having two operating positions a shoe 8 on a Fast is arranged in the lower position, the upper margins are gripped, the shoe is raised to stretch the upper which is then clamped around the toe, the grippers 3 are released, the shoe and clamping means 11 are raised and reversed so as to present the shoe bottom upwards in the upper position, adhesive is injected along the periphery of the insole, and the upper margins are wiped inwardly. The shoe remains in this position while a second shoe is arranged in the lower position, then the clamp is released and the shoe removed and finally the clamp is returned to its initial position by operation of lever 44. Grippers 3 are actuated by knee-operated lever 4, and piston 5 which raises the shoe to stretch the upper is actuated by hand lever 6. Clamping member 11 is operated to clamp or release the shoe by the piston of a hydraulic cylinder which moves forwardly or rearwardly a pivoted balancing beam 15 connected at its ends to the ends of the member 11. The clamping member may be replaced for use with shoes of unsymmetrical shape. The appartus includes a toe support 26 adjusted by means of screw 27 (not shown) and a spring loaded heel support 7. The clamping head 12 carrying the clamping member 11 is mounted on a spindle 27 which has grooves 31 and gearing 30 and is rotatable in a member 29 (not shown). The latter is moved heightwise, by a piston 43 (not shown), in a guide 32 having rails 34, 35, and a rack 36. Portions 38, 40, and 37, 39 of the rails fit the grooves 31 and permit the spindle to move heightwise but prevent rotation, but as the spindle moves through the portion 41, 42 rotation is permitted and is brought about by engagement of gearing 30 with rack 36. The shoe is thus presented, bottom upwards to the adhesive applicator 46 and the wipers 45.

Abstract: 344,776. Electrolytic condensers, rectifiers, &c. BANNING, E., 140, South Dearborn Street, Chicago, U.S.A. Sept. 9, 1929, No. 27388. [Class 37.] In electrolytic condensers, rectifiers, lightning arresters, &c. the electrolyte consists of a solution of a higher polysaccharide such as gum arabic, which generally should be pure, but for condensers &c. for special purposes in which leakage is desired may be adulterated with other compounds such as arabin, dextrin, inulin, arabinose, glucose, or lactose. From 8 to 14 lbs. of gum arabic may be dissolved in 40 lbs. of glycerine, the preferred proportion being 4 parts by weight of glycerine to one part of gum arabic. The mixture is heated until complete solution or dispersion is obtained, the temperature not being allowed to rise above 140‹ C. In another example, gum arabic is dissolved in boiling distilled water in proportions from half an ounce to the pound of water up to a saturated solution. The syrup may be thickened by the addition of sodium borate and boric acid in quantities up to 2 per cent of the weight of gum arabic. Two aluminium electrodes, or one aluminium and one nickel electrode may be employed. An aluminium foil and paper condenser may be impregnated with the electrolyte.

Abstract: 974,016. Gas turbine plant. INGERSOLLRAND CO. July 17, 1962 [July 17, 1961], No. 27459/62. Heading F1G. [Also in Division B2] The invention relates to apparatus for recovering energy from a flow of pressurized gas containing entrained particulate material, the apparatus comprising an annular passage through which the pressurized gas flows, vanes being disposed in the passage to impart rotation to the gas flowing therebetween whereby the particulate material is caused to flow adjacent the outer periphery of the annular passage. A bladed turbine rotor is so arranged that the blades are disposed in the annular passage to be acted upon by gaseous fluid substantially free of entrained particulate material, means being provided to receive and discharge the separated particulate material. In the embodiment shown, the gaseous fluid under pressure, for example the exhaust gas from the catalytic regenerator of a fluidised catalytic cracking process, or the exhaust gas stream from a blast furnace used in steel making, is caused to flow through the annular passage 19 in which is disposed a ring of vanes 17 which impart a rotational motion to the gas flow whereby the particulate material is caused to flow adjacent the inner surface of the outer wall 12 of the annular passage 19, the material flowing into an annular chamber 26 formed by the curved wall 25 of a housing 21. The material is discharged from the chamber 26 through openings 27. The gas stream which has been cleaned of the particulate material passes into an annular passage 30 where it is directed by inlet guide vanes 18 on to the blades 33 which are mounted at the periphery of the turbine rotor 32, the rotor being thereby driven.

[Class 108 (iii)] A resilient mounting comprises two metallic members each having a leg extending substantially parallel to the direction of the load and a leg extending substantially at right-angles to the first leg, one of the members being inverted with respect to the other and having its legs extending substantially parallel to the legs of the other member and rubber bonded to and between the sides of the legs of both members extending in the direction of the load. The mounting shown in Fig. 3 consists of a channel-member formed of angle-irons 1, 2 and an inverted angle-iron M, one leg 9 of which is interposed between and separated by rubber or like material R from the legs 4, 6 of the angleirons 1, 2, the rubber being bonded preferably by vulcanization to the legs 4, 9, 6. The machine or like to be supported rests on the leg 8 of the angle-iron M stressing the rubber in shear, a space A beneath the edge of the leg 9 allowing vertical movements of the leg. The rubber may be permanently compressed between the legs 4, 6. In order to prevent complete collapse of the mounting in the event of failure of the bond between the rubber and metal parts &c., at least one double-angle member 10 is secured to the legs 3, 5 and extends with clearance through holes 13, 14, 17 in the legs 6, 9 and rubber respectively and through a slot 15 on leg 4.

The mounting shown in Fig. 8 is circular in plan view and is centrally secured between the supported and supporting members. Peripheral openings 34 in the channel-member C<11> facilitate shear stressing of the rubber, the rubber portions R" between the openings being compressed.
