Title: Improvements in or relating to embossing blocking & stamping machines
IPC: B41B1/18
Filed: 1923-07-13
Abstract: 222,968. Woodward, O. J. July 13, 1923. Holders for loose types; type-bars.-In an embossing machine, mor.& particularly for producing embossed cards, the embossing types are set in a frame slid on to the pressure member of the machine and are supported by bars which are adjustably and positively held in the frame and adapted to form spacing-pieces between adjacent rows of type according to the width of bar selected. The frame is substantially rectangular in form, three of the sides 1, 2, 3 being formed with grooves 5 having bevelled sides 6 while the remaining side 4 is formed as a flat plate having a thickness equal to the thickness of the other sides below the grooves 5. To support the type 17, bars 10 are provided having flanges 19 engaging the grooves 5 and being recessed at 20 to take the flanges of the type. The bars may be arranged parallel to the side 1 and clamped by a screw 22, or may be placed parallel to the side 2, the upper part of the side 3 being pivoted at 8 to allow of their insertion and a screw 21 being provided thereon to clamp them in position in the latter case. Some of the bars 10 may be formed to act as spacers only and have a line cutter 25, Fig. 4, or punches for punching holes formed thereon. The bevelled parts 6 of the grooves 5 serve to hold the frame on the pressure member 24 of the machine by engaging similarly bevelled projections on this member. Handles 23 may be provided on the frame.

Title: Process and equipment for developing printing out material
IPC: G03C5/18
Filed: 1974-04-25
Abstract: 1463686 Developing apparatus for printing-out materials IRODAGEPIPARI ES FINOMMECHANIKAI VALLALAT 25 April 1974 [25 April 1973] 18206/74 Heading G2X In a process for developing printing-out materials the material is located in a developing chamber which is maintained at a higher temperature than the inlet temperature of the developing gas. This prevents condensation of the gas in the chamber. The apparatus comprises a tank 50 containing developing liquid e.g. ammonium hydroxide solution; a supply line including a liquid pump 20 which pumps liquid from the tank to a vaporizer 10 in which developing gas is educed from the liquid, the gas then flowing to a developing chamber 40. The chamber 40 and vaporizer 10 are provided with heaters (409) Fig. 2 (not shown) and 106, and with temperature control means 408 and 108 respectively, the controller 408 maintaining the chamber 40 at a higher temperature than that maintained by controller 108 in the vaporizer 10. The vaporizer is divided by a dish 102 Fig. 4 into which the liquid is pumped until it reaches the top of a spillway 105. The liquid then drops into the areas below the dish where it rises to the level determined by overflow 107 and is heated by heater 106. The ammonia vapour rises through bubble chimney 103 and is forced through the liquid in dish 102 by a bubble cap 104 to give ammonia rich developing gas which passes through outlet 110 to a three way valve 30. The valve is controlled by temperature controller 408 so that if the temperature of chamber 40 is not higher than that of the vaporizer 10 the gas is returned via line 830 to the tank 50. If chamber 40 is at the correct temperature the valve 30 passes the gas via line 820 and inlet 416 into chamber 40, through which the material is transported by rollers. The space around the rollers is enclosed by covers resiliently engaging the circumferential and end surfaces of the rollers.

Title: Improvements in or relating to Barbed Wire.
Inventor: ROGERSON WILLIAM HENRY
IPC: B21F25/00
Filed: 1916-12-20
Abstract: 112,152. Rogerson, W. H. Dec. 20, 1916. Wire.-In making barbed wire, pointed barbs are automatically positioned on the main wire and are bent and held in position until welded by electric transversely - moving welding dies. The main wire 25 is intermittently fed through automatically released spring-clamps 26 by rollers 23 driven by toothed gearing and carrying adjustable projections 24, and moves along a guide 27 to pairs of oppositely moving electric welding-dies 17, 18, Figs. 1 and 4, which have V-notched ends and are slidably mounted in plungers 4, which are simultaneously reciprocated by bell-cranks 7 actuated by toothed gearing 21, 22 from belt-driven fast and loose pulleys. The dies' are retracted by a spring 15 and carry separate insulated electrical connexions 20. The barb wires 38 pass around pulleys 35 through guides 36, automatically released spring clamps 26<a>, and are fed by rollers 37 through guides 40 so arranged as to slightly incline the ends of the wires, one passing above and one below the main wire 25. The wires are fed against a stop 40 and are held by the dies 17, 18 until cut off obliquely by transversely moving tools 42 operated by camactuated levers. The dies 17, 18 complete their movement and bend the barb wires into position when the contact actuating cam 46, Figs. 2 and 8, completes the welding circuit. An overload relay or suitable shunt breaks the circuit when the weld is completed. When the cam 46 closes the contact switch 47, a contactor 48 is engaged and switches in the high-tension side of a transformer and causes low-tension current to pass across the dies until the weld is completed and the current short-circuited by contact pieces 52. The current operating through an overload relay 49 then opens the contactor 48 to break the hightension circuit. When the overload relay opens it closes the circuit of a subsidiary coil 50, which prevents the plunger 51 from falling and completing the circuit of the solenoid 48 and consequently the high-tension circuit. When the switch 47 is opened, the circuit 50 is broken and the plunger 51 falls. The complete wire passes over a notched skeleton wheel 28, beneath a second spring-controlled wheel 30, over a third wheel 32, and a travelling wheel 34 to a reel.

Title: Data processing apparatus
IPC: G11B20/18
Filed: 1966-04-26
Abstract: 1,140,291. Data storage. HONEYWELL Inc. 26 April, 1966 [17 May, 1965], No. 18248/66. Heading G4C. Apparatus for detecting drop-outs in data frames successively recorded at predetermined intervals along the length of a multi-channel medium (e.g. magnetic tape), on failing to detect a frame in one of said intervals, counts subsequent frames detected, an error signal being produced if the count exceeds a predetermined value. The tape has 7 channels, one being used for a transverse odd parity bit for each frame, each frame being across the tape. A multi-frame record is followed by a longitudinal even parity frame for the record, separated from the nearest data frame by 3 times the gap between successive data frames (the latter corresponding to a delay of 17Ás). The bits 1 and 0 are recorded as transistion and no-transition of the magnetic medium respectively. Since transverse parity is odd, there should be at least one transition per frame. Referring to Fig. 2, any frame with a transition, on being read, produces a 3Ás clock pulse from 10 which produces 25Ás and 0À5ms pulses from units FPD and RPD respectively, partially enables AND gates 34, 36, 38, and causes a transverse parity check to be performed on the frame. Assuming forward read, signal RF is present. In this case absence of transitions from a frame allows the 25Ás pulse produced by FPD in response to the previous frame to disappear before being replaced by another, so flip-flop 32 is set via AND gate 26, thereby enabling any subsequent clock pulses from 10 to pass through AND gate 24 to counter 42. If the count reaches 2 an error signal is given. Even in the absence of error, the count will reach 1 since the gap between the longitudinal parity frame and the nearest data frame is more than 25Ás. However it is not more than 0À5ms, so there will be no gap between successive pulses from RPD until the parity frame has been passed. When a gap occurs, the flip-flop 32 and counters 42, 48 are reset. For backward read, in which signal RB is present, the parity frame precedes the data frames. The 3Ás clock pulses are counted at 48. After a count of 2 has been reached, gate 30 is enabled so that a missing frame can set flip-flop 32 causing subsequent frames to be counted at 42, an error signal being produced as before on reaching a count of 2. Since the parity frame may be all 0s, the two data frames nearest to it should have a large number of is so that all will not drop out. Similarly (for backward read) the two data frames at the other end of the record should have a large number of 1s. Writing on the tape (forward movement only) is immediately checked by a read-after-write operation.

Title: Improvements in or relating to the refining of crude olefinic nitriles by distillation
Filed: 1945-07-17
Abstract: Aqueous acrylonitrile or one of its immediate homologues is refined by distilling off the nitrile-water azeotrope from the crude material, condensing the distillate, permitting the condensate to stratify into a predominantly nitrile layer and an aqueous layer, and separating the two layers.  In an example, crude aqueous acrylonitrile is allowed to separate into two layers and the lower aqueous layer is discarded.  The nitrile layer is fractionated and, for the temperature range 70-75 DEG  C., the vapours of the azeotrope are condensed at the reflux head and allowed to stratify into two layers therein; the lower nitrile layer being returned to the still. A wet acrylonitrile fraction is then removed at a temperature of from 75 DEG  to 77 DEG  C.  Finally, dry acrylonitrile is distilled from the still residue at 77 DEG  to 78 DEG  C.  The same method may be used for the dehydration of crotonic nitrile; the cis- and trans-isomers being then distilled separately from the still residue at 108 DEG  and 120 DEG  C. respectively.  In other examples, an aromatic hydrocarbon is utilized to extract nitrile from the aqueous layers.  Thus crude acrylonitrile is allowed to separate into two layers, the aqueous layer is withdrawn, and extracted with xylene. Acrylonitrile is removed from the xylene extract by distillation, and the residue, after filtration from polymer, is used for a subsequent extraction.  The nitrile layer is fractionated as described above until the temperature reaches 75 DEG  C., the nitrile which was extracted with xylene is then added to the still content, and fractionation is continued.  After removing wet acrylonitrile at 75 DEG  77 DEG  C., dry acrylonitrile is obtained at 77 DEG  to 78 DEG C.  The wet nitrile is added to a subsequent initial nitrile layer; and the water obtained from the azeotropic distillation, is added to a subsequent aqueous layer.
