Title: Improvements in and relating to indicating mechanism for cash registers
IPC: G06C11/02
Filed: 1924-06-04
Abstract: 239,278. Haddan, A. J. H., (National Cash Register Co.). June 4, 1924. Cash registers; tablet indicators.-In a key set and operated machine an arrangement of tablet indicators is provided wherein the indicators are selected and moved to a display position by the operation of the item entering means, and are viewable both to the front and rear of the machine. The key levers 25, on depression in the usual manner, actuate the appropriate totalizer actuating segment 33 and the cam shaft 42, and each item as it is entered is printed on a record-strip 125, Fig. 7, adapted to be fed forward at each operation by a spring-pressed pawl 128 carried on an arm 129 secured to the key coupler trunnion 28. A hammer platen 130 cooperating with a spring plunger 131 is operated by a cam on the shaft 42 to press the recordstrip and usual inking ribbon 132 against the item type wheels 35. Each segment 33 engages a pinion 46, Figs. 4 and 5, loose on a shaft 49 and each pinion 46 is associated with another pinion 47 gearing with a segment 50. Integral with each segment 50 is a second segment 51 engaging a rack 52 pivoted to an indicator selecting arm 56. The arms 56, which are freely mounted on a rod 57 and a telescopic sleeve 58, Figs. 1A and 5, are associated with a corresponding indicator supporting frame 63 the hubs 64 of the end frames, and those adjacent thereto being secured to the rod 57 and sleeve 58 respectively so as to move the front and rear indicators in unison. The third hub 64 is freely mounted on the sleeve 58. The frames which support the indicators in the usual manner are moved to positions corresponding to those of the selecting arms by pairs of arms 68 having rollers engaging the cam slots of the frames and arms. The arms 68 are pivotally mounted on arms 75 secured to a rod 76 adapted to be rocked at the proper time by an arm 80 secured to the hey coupler trunnion 28. The arm 80 has a cam slot 81 which cooperates with a roller 82 on a pivoted arm 83 connected by a link 85 to an arm 86 secured to the shaft 76. After adjustment, the frames are held in position by an aligning pawl 88 secured to a shaft 89 adapted to be rocked by an arm 90 and lever 91 from a cam on the shaft 42. The adjusted indicators are raised to display position by the usual lifting bar which is reciprocated by segmental gearing 107, 109 and a link 113 to the lower end of which is pivoted an arm 112 carrying a roller 111 in engagement with the slot 81.

IPC: C01B32/50
Filed: 1930-05-02
Abstract: Carbon dioxide obtained by the catalytic decomposition of carbon monoxide or gases containing carbon monoxide under pressure is liquefied by cooling at the same pressure in a second vessel. A valuable gas soot is also obtained.  The process may be carried out continuously in an enclosed apparatus comprising a reaction vessel, a condensation vessel placed at a lower level and connecting tubes, a circulation of gases being maintained by cooling the gases rich in carbon dioxide leaving the reaction vessel and heating the gases poor in carbon dioxide leaving the condensation chamber, and fresh carbon monoxide being introduced to maintain the pressure as required. According to an example, technical carbon monoxide is decomposed in the presence of a nickel catalyst at 100 atmospheres pressure and 350 DEG  C.  The reaction gas rich in carbon dioxide is cooled to -10 DEG C. and the residual gas leaving the condensation chamber and still containing some carbon dioxide is led back for further decomposition.

Title: Improvements in and relating to impact tools
IPC: B25D11/06
Filed: 1941-10-23
Abstract: 551,031. Percussive tools. DEHN, F. B. (Clover, F. G.) Oct. 23, 1941, No. 13640. [Class 124] In a sealing hammer or like percussive tool, impact is imparted to the tool 18 by an inertia weight 17 which is shorter in length than the distance between the tool and a rotating cam 15 or like driving means, whereby the weight strikes the tool only after it has been disengaged from the cam, a strong spring 31 or like yieldable means absorbing substantially all the shock when the tool is out of contact with the work or only pressed lightly against it. The tool includes a split casing 11 for clamping on to the casing of a motor-driven drill, or the casing of an electric, pneumatic, or other preferably variable high-speed motor, and a tapered shaft 10 for rotating the cam. A light spring 30 serves to raise the inertia weight into contact with the cam, and the top of the weight may be somewhat dome-shaped. When the shaft 10 has rotated about 90 degrees after each main blow, the weight is returned to the cam by the spring 30, thereby causing a subsidiary blow. The base of the central portion 34 of the casing is formed with a polygonal hole to receive the correspondingly shaped upper end 37 of a non- rotating tool, or the round upper end of a tool which 'is rotated by hand. The casing 11 is closed by a screw cap 19 which may be removed for the insertion of an intermediate casing with additional cams 22, 23, weights 25, 26 and tools 27, 28.

Title: Apparatus and methods for assembling cans or other containers with a carrier
Inventor: POUPITCH OUGLJESA JULES
IPC: B65B17/02
Filed: 1959-04-22
Abstract: 922,591. Packaging machines. ILLINOIS TOOL WORKS Inc. April 22, 1959, No. 13727/59. Class 94(1). A machine for engaging a carrier with a group of cans, the carrier being in the form of a resilient apertured sheet, comprises means to position the carrier over the grouped cans and means to move it in the direction of the cans axes to force its apertures over their upper beads. Cans 22 are fed on to a table 46 by a conveyer 20 and the leading pair abut a stop 48. A laterally slideable separator 60 then checks oncoming cans and a vertically moving head 24 holding beneath it a carrier 28 descends towards the cans. The cans are positioned to receive the carrier initially by a pusher bar 133, Fig. 7, moveable obliquely by piston rod and cylinder means 135, 137 which urges them towards the stop 48, and finally by elements 132, 134, 164 actuated by downwards movement of the head 24. The elements 132, 134, Fig. 6, consist of plates which rise above the level of the table 46 to form with the stop 48 and an ejecting plunger 62, an enclosure towards the sides of which the cans are displaced by the elements 164 rising between them. The head then forces the carrier over the cans with consequent distortion of the aperture rims, and lugs 102, Fig. 9, are lowered slightly by linkage 120 an cam elements 116 to release the carrier as the head rises. The completed package is ejected on to a conveyer 34 by the plunger 62, the latter having mounted above it a plate 30 with lugs 76 for engaging a carrier from the base of a stack 26. The plate also has vacuum means (not shown) for gripping the carrier. As the plate moves forward, it slides the carrier between the lugs 102 and the base of the head. The lugs 102 rise to gripping position and the plate and plunger withdraw. In another form of head, Figs. 12-17, 19, 20, (not shown), the carrier is gripped by depending pins which outwardly distend the apertures prior to their passing over the can heads. This head may be used with a carrier as shown in Fig. 18.

Patent GB-186372-A (GB)
Title: An improved method of removing ink from print paper
IPC: D21C5/02
Filed: 1921-05-17
Abstract: In removing ink from paper, colloidal material such as Bentonite, having over 50 per cent of its particles of diameters less than fifteen ten-thousandths of a millimeter, or more than 70 per cent colloidal, is used.  A mixture of cut or beaten paper, alkaline material such as sodium carbonate, and Bentonite or the like, is agitated in running water.  The paper material is held by a screen while the water carries off the Bentonite or the like and ink.  The material is then neutralized with an acid or acid salt, such as acid sodium sulphate or aluminium sulphate, and thus brightened.  The material may then be sized, dyed to give it the right shade, and then mixed with pulp and re-made into paper.
Patent GB-475362-A (GB)
Title: Improvements in or relating to free wheel clutches
IPC: F16D41/08
Filed: 1936-05-16
Abstract: 475,362. Free - wheel clutches. FISCHER, S. May 16, 1936, No. 13887. Convention date, May 18, 1935. [Class 80 (ii)] In a free wheel clutch, a roller (or ball) 31, Fig. 1, arranged between driving and driven members 1, 2 and engaging a double cam groove G in the member 2, is urged in the forward direction S, through a member 5<1>, by a spring 6 abutting against a block 4 fixed to the member 2, and is urged in the reverse direction S<1>, through a member 5<2>, by a spring 7 abutting against a member 9 which is adjustable circumferentially relative to the member 2. The member 9 abuts against the wedge surface 10<1>, Fig. 3, of a pin 10 which is guided in side flanges of the member 2 and in the block 4 appertaining to the adjacent roller and which is secured to an axially movable collar 14. If the pin 10 is drawn fully outwards, the spring 6 overbalances the spring 7 and positions the roller for unidirectional forward drive. If the pin 10 occupies an intermediate position such that the spring 7 counterbalances the spring 6, the roller is held in neutral position. If the pin is pushed fully inwards, the spring 7 overbalances the spring 6 and positions the roller for unidirectional reverse drive. Alternatively, the wedge pin may be arranged radially or by replaced by a rotatable cam, and the clutch roller may act axially instead of radially. If all the rollers in the clutch are similarly controlled, the clutch provides a reversible unidirectional drive, with a neutral position. As shown in the right-hand part of Fig. 1, however, each alternate roller 3<2 >is urged only in the forward direction, by the spring 6 acting through the member 5<1>. A clutch so constructed provides alternatively bidirectional and unidirectional forward drive. As shown in the left-hand part of Fig. 1, the wedge pins 102, which are associated with alternate rollers 3<2> and which are secured to the collar 14, are formed as shown in Fig. 4. In this case, with the pins 10 and 102 fully retracted, all the rollers are positioned for unidirectional forward drive. With the pins pushed partially inwards, as indicated in Figs. 3 and 4, the wedge surfaces of the pins 102 have not yet come into action, while the rollers 3<1> have been moved into position for unidirectional reverse drive. The clutch now provides bidirectional drive. With the pins pushed fully inwards, the rollers 3<2> are also moved into position for unidirectional reverse drive. Alternatively, the wedge pins of the two groups of rollers 3<1> and 3<2> may be controlled separately. The Specification as open to inspection under Sect. 91 states also that the spring 6 may simultaneously be controlled by a pin having a wedge surface parallel or slightly inclined to the wedge surface of the pin 10. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,208,047. Ceramic wafers; ceramic laminates. P. R. MALLORY & CO. Inc. 22 March, 1968 [23 March, 1967], No. 13944/68. Headings B5A and B5N. [Also in Divisions C1 and H1] A method of fabricating a ceramic wafer comprises the steps of preparing a slurry of a ceramic material and a flowable binder, forming a film of the slurry, drying it and cutting it into a plurality of pieces, embossing a wafer made up of one piece or of several pieces laminated together, with a pattern of grooves to produce a plurality of substantially coplanar surfaces, driving the flowable binder out of the wafer and maturing the ceramic material by firing in a kiln, applying a layer of paste to the coplanar surfaces and firing again in a kiln to bond the paste to the wafer surface. The flowable binder used is an organic thermoplastics material, such as 12% polyvinyl chloride. The slurry film is fed on to a driven stainless steel belt coated with a release agent such as Teflon (Registered Trade Mark) silicone oil or ammonium stearate to prevent the film sticking, passes under a blade to control its thickness and through an oven to dry it. After cutting, the dried pieces are stacked by hand to form the final laminated wafer of the required thickness, which is consolidated in the embossing operation wherein V-grooves are formed along which the wafer can be easily broken and other U-grooves are formed to provide a pattern. The laminated wafers are produced by stacking the green ceramic squares, each of thickness of 4 to 7 mils, by hand to produce the required thickness. Heat and pressure is applied to the laminated wafers in the embossing unit by means of heating elements and an hydraulic cylinder acting through a die and pressure block. Typical temperatures and pressures are 75�-400� F. and 1000- 20;000 p.s.i.

Abstract: 1,149,003. Wired broadcasting system. COMMUNICATIONS PATENTS Ltd. 30 March, 1967 [30 March, 1966], No. 13991/66. Heading H4R. In a system for distributing a colour television transmission comprising a brightness signal and two colour information components, the signals are transmitted over the network in the following form: (i) a modulated carrier wave brightness information signal having a bandwidth 9 on a carrier (10À5 MHz) 8; (ii) a suppressed carrier wave colour information signal 10, 11 in respect of both colour components; and (iii) a pilot carrier wave signal 12, 13 in respect of the frequency of the suppressed carrier wave and of one of the colour components ; and a receiver 6, 7 includes a synchronous detector 54 for demodulating the signal (ii) to recover the colour component not indicated by signal (iii) with the aid of a re-insertion wave the frequency of which is determined by the pilot signal (iii). The colour television signal received by aerial 14 produces signals (i) and (ii) through a modulator 21 and a vestigial sideband filter 24, and signal (iii) by causing colour bursts on line 19 to produce a carrier corresponding in frequency and phase to the suppressed carrier, and applying it chopped in bursts by a line scan frequency on 20, to a unit 33 where it is added to information concerning the frequency of the colour signal before modulating the pilot from oscillator 26. The signals are combined in an output stage 25. In a receiver a video frequency brightness signal is produced on line 41 by a filter 38 which passes band 9 to an envelope detector 40, and a colour information signal selected by a filter 42 passing band 11 is applied to a colour recognition device 44 and a subtraction circuit 43. In the colour recognition device a phase comparison with the pilot modulation is effected, and its output is applied to reverse in switch 52 the phase of a re-insertion oscillator 50 energized by colour burst signals separated in unit 47, for application to the synchronous detector 54 producing a colour information signal. The other colour information signal is produced in an envelope detector 48 and made available on line 49. When the frequencies of oscillators 26 and 29 are chosen to be identical, envelope detector 48 may be replaced by a synchronous detector.
