Title: Improvements in or relating to printing telegraph apparatus
IPC: H04L17/30
Filed: 1938-07-19
Abstract: 517,297. Type-printing telegraphy. STANDARD TELEPHONES & CABLES, Ltd., and HYDE, G. A. M. July 19, 1938. No. 21418. [Class 40 (iii)] In a printing telegraph receiver having a type-head rotatable to a position dependent on the received signal, the type-head is caused to rotate in the direction which requires the minimum amount of rotation to reach the desired position. The received signal selectively charges condensers QA ... QE and when the stop impulse is received relays ST, STA (windings not shown), operate so that relays A, B, C, D and DR, E and its auxiliary relays ER and ERR are selectively energized. A printing relay PR is operated and completes a circuit for a relay PRA which at its contact pra2 connects ground to the armature dc1 of a relay DC. Three brushes DCa, DCb, DCc are rotatable with the type-head over a bank of contacts 12 corresponding to a further bank 13 having contacts corresponding to the characters to be printed and functional operations such as figure shift &c. The brushes DCa, DCc are connected at contacts pr2, pr3 to different potentials. The brush DCb is located centrally between the brushes DCa, DCc and to one end of the winding of the polarized relay DC. The winding of the relay is also connected through the contacts of the relays A .. E to a contact on the bank 12 corresponding to the character to be printed or the operation to be performed. According to the position of the contact to the right or left of the brush DCb, the relay DC is operated to its marking or spacing contact m or s and connects ground to the leads ACD or CD thereby switching in a member which produces rotation of the type-wheel in the desired direction. The type-wheel is stopped in the desired position by the marking of a contact in a third bank (not shown) by a circuit closed by relays A ... E. A relay TH then operates the printing magnet THA, At contact th2, the spacing magnet SP is operated and at contact sp1 the locking circuit of the printing relay PR is opened. The " answer-back " apparatus is brought into operation by the figure-shift signal followed by the code-combination for the letter D. On the receipt of the figure-shift signal and the rotation of the type-wheel relay FG operates and locks-up, and when the typewheel has been positioned corresponding to the letter D ground is connected over the contact fg2 and the line AB to bring the answer-back apparatus into operation in a manner described in Specification 517,308. Fig. 3 shows a modified arrangement, used in place of the third bank of contacts, in which the number of contacts operated by the relays A ... E are reduced by having four wipers T1 ... T4 rotatable with the type-wheel and moving over banks of contacts which are connected in such a way that a circuit can be completed for the relay T only when the brushes T1 ... T4 are on the contacts of the bank 14 ... 17 corresponding to the selected character.

Abstract: 896,501. Parachutes. G. Q. PARACHUTE CO. Ltd. July 3, 1959 [July 4, 1958], No. 21491/58. Class 4. A parachute pack comprises a wrap or cover for a parachute canopy and at least part of its rigging lines, means for keeping this wrap normally closed, an outer cover or pack base to be worn by the parachutist, means for keeping this outer cover normally closed with the wrap stowed inside it, and a handle secured upon the wrap to enable the parachutist to throw it to a distance, initial operation of the handle releasing the cover and a subsequent movement of the handle serving to throw the wrap to a distance, the wrap being then opened by the pull of the rigging lines, thereby allowing the deployment of the parachute. The wrap or cover 10 which encloses a reserve parachute 11 is provided at one end with loops 14 which are passed through slots 15 in the other end, the loops being retained by the shroud lines 16 of parachute 11. The shroud lines 16 are drawn through the overlapping ends of the wrap 10 and laid first through loops 14 and subsequently through other loops 17 which form extensions of elastic tapes 18 secured by ties 20 to beckets 21, the tapes serving to unwrap the cover when loops 14 are freed. A pocket 22 of substantially cruciform shape has two side flaps 23 slidably mounted on tapes 18, a top flap 24 and a lower flap 27 secured to another elastic tape 30, the folded end 32 of which is sewn to cover 10. A handle 25, secured to cover 22, carries two rip-cord cables 26 having pins 28 which engage locking cones 29 fixed on the outer face of cover 10. The shroud lines 16 after passing through loops 17 are passed through loops 36 attached to an outer cover formed with side closure flaps 34, end flaps 35 and lift straps 37 for attachment to the parachutist's harness. The folded wrap 10 and parachute 11 are laid on the rigging lines 16 on the outer cover, the flaps 34, 35 of which are folded over the wrap with their eyelets 39 engaging cores 29 to be locked by pins 28. In operation the parachutist initially pulls handle 25 to free flaps 34, 35 and then throws the wrap sideways so that lines 16 will initially draw out of loops 14 and 17 to free a pilot parachute (not shown) and reserve parachute 11, the pull of these subsequently withdrawing lines 16 out of the loops 36 in the cover.

Patent GB-428986-A (GB)
Title: High strength lithopone
IPC: C09C1/06
Filed: 1934-07-24
Abstract: <PICT:0428986/III/1> High strength lithopone is produced by mixing a crude precipitate of zinc sulphide, prepared by treating zinc sulphate with hydrogen sulphide gas, with a crude precipitate of normal lithopone, subjecting them mixed in the form of a slurry to the conditioning environment, removing the sulphuric acid present, e.g. by washing, and finally treating by the usual subsequent operations of lithopone manufacture.  Co-precipitated zincsulphide and barium sulphate may be included in a slurry in which the precipitation of zinc sulphide by the reaction between hydrogen sulphide and zinc sulphate is proceeding.  In another form, zinc sulphide and barium sulphate are simultaneously precipitated by the reaction between barium sulphide and zinc sulphide and an aqueous solution of zinc sulphate.  A part only of the crude lithopone may be exposed to the slurry in which the zinc sulphide is being precipitated, e.g. a crude high strength lithopone containing 75 per cent of zinc sulphide may be produced by the process and then mixed with sufficient crude normal lithopone to bring the zinc sulphide content down to 50--60 per cent.  As shown, the slurry is produced in a series of tanks 5, 5<1>, 5<11> through which hydrogen sulphide gas is fed by pipes 8, 8<1>, 8<11>.  Purified zinc sulphate solution is introduced, preferably continuously, into tank 5 through a pipe 21, and barium sulphide liquor into any one or two or all of the tanks, e.g. through pipe 41.  The tanks have Venturitube eductors 6, 7, 6<1>, 7<1>, 6<11>, 7<11> and pumps 20, 31, 31<1>, 31<11> for withdrawing and remixing the gas and liquid.  The barium sulphide produces with part of the zinc sulphate present a slurry of crude lithopone which circulates with the zinc sulphide slurry through the tanks.  In a modification, a slurry of crude lithopone may be introduced in place of the barium sulphide and the concentration of the zinc sulphate solution may be increased to compensate for the dilution by the water in the slurry, or the slurry may be in suspension in a solution of zinc sulphate equal in strength to the fresh zinc sulphate solution added.  In a further form, crude lithopone slurry is added through a pipe 44 to an ageing tank 43 where it is mixed with the crude zinc sulphide slurry from tank 5<11>.  The reaction between the zinc sulphate and the hydrogen sulphide continues during the ageing which may last for 4--12 hours. The crude pulp produced is washed, e.g. on a filter, and the filter cake repulped and p  end-pointed and finally subjected to the usual operation of filtering, drying, calcining, quenching, wet disintegration, drying and dry grinding.  Specification 423,343, [Group XII], is referred to.

Abstract: 640,173. Expanding-pulley gear. HOE & CO., Ltd., R. Aug. 8, 1947, No. 22123. Convention date, Dec. 23, 1938. [Class 80(ii)] [Also in Groups XVI and XXXVII] In a printing-machine in which rollers or pumps for controlling the supply of water to planographic printing-plates are driven from the printing machine the rate of supply of water to the plates is controlled by mechanism which is so arranged that the increase in speed of the printing-machine causes an increase in speed of the water supply which is at a lower rate than increase in speed of the machine. In one method of doing this the water supply is driven by an expanding-pulley gear. The drive of the damping supply roller 26, or the shaft of a pump-actuating device, is controlled by a Reeves pulley device comprising two expanding-pulleys 105, 106, Fig. 8, driven from a motor by a shaft 111 to which is fitted a pivoted centrifugal member 112 which, as the speed of shaft 111 increases, tends to assume a vertical position. An adjustable link 113 is connected to the member 108 of the pulley 105, and thus expands the pulley and so varies the rate of speed increase of the damping drum 26 as the machine is driven faster. The expanding-pulley can be adjusted by a screw 118 and lever 123 to control the normal speed of the drum 26. The machine is described in the abridgement for Group XVI.
