Title: Improvements in and relating to the manufacture of lace on lace curtain machines
IPC: D04C5/02
Filed: 1927-02-22
Abstract: 288,005. Stirling, Auld, & Co., Ltd., and Borland, G. Feb. 22, 1927. Lace.-Coloured pattern effects A are produced on lace curtains &c. by causing coloured threads d controlled by a spool bar to cloth as desired and where they do not cloth, to float while uncoloured threads e in the same bar either cloth or are pillared or tied in, as required. The float threads d<3> are subsequently cut away. Three guide bars are used, controlling warp threads fillet net or other ground threads and threads. The gear spindles e are formed with numbered cards select the jacks while the carriages are in the back combs after the spool bar has risen one gait and are punched according to the clothing to be made, each hole corresponding to a jack to be selected. The unselected jacks intercept the threads as the spool bar rises one or more gaits further. The carriages then pass and tie the threads raised by the second movement of the spool bar. Previous to the return of the carriages a selection is made by the even-numbered cards, which are punched for clothing the threads d, e and for pillaring the white threads e alone. Thus the coloured threads d intercepted by jacks not selected by even-numbered cards are left loose or floating but the white threads e either cloth or pillar. In a modified method the unpunched areas of the cards bring in the clothing, or the clothing and pillaring as the case may be.

Title: Improvements in apparatus for the manufacture of rubber-soled footwear
IPC: B29C35/00
Filed: 1930-02-14
Abstract: 349,021. Vulcanizing boots &c. COLLINS, C. H. R., 11, James Street, Joppa, Edinburgh. Feb. 14, 1930, No. 5065. [Classes 70 and 87 (ii).] Rubber soles are applied to footwear by vulcanizing apparatus comprising a hot table 1, a bottom plate 3 of the mould, which may be in one with the hot plate or bolted to it, a sole plate 5 and the main body of the mould 7 which is pivoted on a horizontal hinge 8. The mould body 7 is formed with an opening to admit the valve for inflation of the usual rubber or other bag within the shoe, and is also recessed to accommodate a sleeve 12 of metal, vulcanite, bakelite, asbestos, rubber, canvas, &c. which is fitted round the shoe before its insertion in the mould to protect the upper part of the shoe and to prevent the rubber from spewing. Opening of the mould is facilitated by a spring-pressed plunger 9 in which the tension of the spring 20, Fig. 6, is regulated by rotating a square rod 9a sliding in a nut 21. The plunger may be used to close the mould by providing a connection for the supply of compressed air. The closed mould is locked by a T-shaped bolt 14 hinged to the front of the hot-plate and provided with a cam 15b cooperating with a cam 15a on the mould, this bolt being also provided with a tail portion adapted to raise a plunger 17 engaging the under surface of the mould to initiate the opening movement. To raise the shoe from the sole-plate after vulcanizing a piston 15 is elevated by the action of a wedge 18 pushed forward by an abutment of the hinge 8 when the mould is opened. The wedge 18 may be replaced by a compressed air supply pipe having a valve operated by the abutment on the hinge. Specification 266,142, [Class 70, Indiarubber &c.], is referred to.

Title: Electrical impulse-counting apparatus
IPC: H03K21/00
Filed: 1945-03-02
Abstract: 585,562. Pulse counting circuits. ACE ELECTRONICS, Ltd., WELCH, L. C., and COOK, R. J. March 2, 1945, No. 5257. [Class 40 (v)] [Also in Group XIX] An electrical impulse counter comprises a continuously rotating system with a synchronized marking pulse for registering a definite number value, wherein each impulse changes the phase of the marker pulse relative to the rotating system by a definite fraction of a cycle. In Fig. 3, sine waves are fed from oscillator 2 through 10 : 1 frequency divider 3 to a phase splitter 4 which supplies two equal outputs in phase quadrature to the deflection plates of the cathode-ray tube to produce a circular time base 35 on the screen (Fig. 4). Primary oscillations are also fed through another 10 : 1 frequency divider 6 and circuit element 8 to produce a series of sharp pulses which cause a radial deflection 36 on the cathode-ray tube in synchronism with the circular trace. Impulses from photo-cell 31 or a standard frequency oscillator 32 operate a biassed multivibrator 9 which controls a phasing device 5 comprising a phase-splitter in combination with a pair of ring modulators. This arrangement advances the phase of the oscillations applied to the frequency divider 6 by 36 degrees for each impulse, which corresponds to a change of 36 degrees in the phase of the marker pulse 36, moving it one division along the scale 37. The higher decade 370 is produced by the chain 38 to 41, 80. The primary frequency is restored without losing the phase division produced in divider 6 by additionally combining the output from a 9 : 1 multiplier 39 with the output from divider 6 in the mixermodulator 38. Further phase division is then produced in the 10: 1 divider 41 and sharp pulses are produced in impulse shaper 80 to provide a second radial deflection 360 on the indicator in synchronism with the circular time base. Thus, every 10 impulses from source 31 or 32 produce an advance of 36 degrees in the phase of marker pulse 360, moving it one division along the scale 370. Interference between two marker pulses 36, 360 during coincidences on the time base is prevented by utilising a multi-vibrator to sensitize impulse shapers 8, 80 alternately and present each marker in succession on separate traces. The system may be reset by closing switch 34A which locks the divider 6 in a fixed phase relationship to the scan voltages, corresponding to zero indications on scales 37, 370.

Patent GB-159196-A (GB)
Title: Improvements in preparation of artificial base-exchanging bodies
IPC: C01B33/46
Filed: 1921-02-18
Abstract: As open to public inspection under Sect. 91 (3) (a) of the Act, it is stated that an hydrated silica, called "cyclo-silicic acid," is obtained by the treatment of a silicate of aluminium or a heavy metal or a double silicate of an alkali metal and aluminium or a heavy metal, with a strong acid.  It may be employed in the treatment of water for the removal of bases.  This subject-matter does not appear in the Specification as accepted.ALSO:Base exchanging bodies substantially saturated with alkali metal oxide are precipitated by the interaction of a salt of an amphoteric metal such as aluminium, iron, zinc, tin, manganese, lead, titanium, molybdenum and chromium with excess of an alkali-metal silicate in dilute solution.  In order to increase the hardness of the final product and also to prevent hydrolysis of the amphoteric metal salt, a solution containing salts of two amphoteric metals may be used, and neutral indifferent salts such as sodium sulphate may be added during the precipitation.  The addition of acid also prevents hydrolysis and excessive washing improves the quality of the precipitate.  In examples in which aluminium sulphate and sodium silicate are used in the presence of sodium sulphate which acts as a coagulant, the gelatinous precipitate after standing is filtered off and dried; first by passing air through it and then by heating to 60-100 DEG  C.  The dried press-cake is then thrown into water to make it break up into granules.  An alternative method of saturating the precipitate first formed with alkali metal oxide, when the alkali silicate is added to the salt of the amphoteric metal is to stop the addition of silicate as soon as the latter is found in the mother liquid and to add instead sodium bicarbonate or carbonate or soda-ash.  The granules may also be quenched in soda-ash solution.  The base exchanging body after use is regenerated by means of a solution of a neutral alkali metal salt; e.g. sodium chloride.  Specification 108,773 is referred to.  The Specification as open to public inspection under Sect. 91 (3) (a) also contains the following subject-matter.  Silicates of aluminium and the heavy metals and double silicates containing alkali are prepared by the interaction of the metal salts and alkali silicate in dilute solution.  As examples of the metals that may be used, silver and copper are mentioned besides those stated above.  By treating the products containing alkali-metal oxide with acids, the alkali metal is removed; and "metallo-silicic acids" are obtained suitable for the removal of bases in the treatment of water.  For regeneration of the used materials, it is stated that acids such as sulphuric, hydrochloric, or carbonic acid may be employed.  This subject-matter does not appear in the Specification as accepted.
