Abstract: 806,624. Tufting machines. CABIN CRAFTS Inc. Jan. 31, 1957 [June 20, 1956], No. 3434/57. Class 112 A device adapted to repair tufted rugs comprises a support, a motor mounted thereon, a tufting needle, a plunger co-operating with the needle to determine the height of the tufts produced, operative connections from the motor to reciprocate the needle and plunger continuously, and means on the support for varying the depth of penetration of the plunger through the rug fibric for varying the height of the tufting. As shown, a motor 18, mounted on a hand-carried frame 10, drives a shaft 23 via a shaft. 20 and gearbox 22. A bar 28 connects a crank disc 26 on shaft 23 to a crosshead 34 slidable on guidebars 36, 38. A tube 40 rigidly connects crosshead 34 to a crosshead 44 slidable on guidebars 34, 46. A crosshead 50, slidable on guidebars 46; 48, carries a loop-retaining plunger P adapted to project through a hollow needle N carried by crosshead 44, the free end of the plunger being notched to engage the yarn Y. A bar 52 is pivoted at one end at 51 to crosshead 50, and is formed at its, other end with a slot 53 engaged by a fixed pin 54. A bar 58 connects a crank disc 60 on shaft 23 to a pin 64 carried by the piston] rod 68 of a pneumatic cylinder 72. A pin 56 on bar 58 engages a slot 159 on bar 52. The piston 70 of cylinder 72 is biased inwardly by a spring 69. A hose 76 connects cylinder 72 to solenoid-operated air valve 75. An electric cable 79 connects the solenoid of valve 75 to a switch 80. When said solenoid is de-energized, piston 70 occupies its inmost position, whereby the stroke of the plunger, and thus the height of the tufting produced, is shortest. When switch 80 is closed to energize the solenoid, air is admitted to the cylinder and pin 64 moves to its dotted-line position, whereby pin 56 is moved away from pin 54 to increase the stroke of the plunger and the tufting height. In repairing tufted rugs, the frame 10 is held by an operator at the back of the rug, and switch 80 is manipulated by an operator at the front of the rug for varying the tufting height to match the existing pattern.

Title: Improvements in or relating to digital information recovery systems
Inventor: COMSTOCK GEORGE E
IPC: G06F11/10
Filed: 1962-01-31
Abstract: 985,233. Magnetic tape stores. POTTER INSTRUMENT CO. Inc. Jan. 31, 1962, No.3675/62. Heading G4C. An arrangement for reproducing recorded binary data comprises a parity checking circuit and a clock error detecting circuit and means responsive to the simultaneous presence of a parity error and a clock error to produce a datacorrecting signal. The recorded data may be either of the kind in which there is a transition at the middle of each clock cell, or of the kind in which each data signal is bracketed by a pair of clock signals. As described, characters are stored on a magnetic tape 2 in the form of three data bits plus one parity bit, the sum of the four bits in each character being odd. The characters are read by a head 1,a recovery circuit 3 providing outputs at 8-11 for the recovered data and parity signals,and outputs at 12-15 for the recovered clock signals. The data and parity signals are applied to a deskewing circuit 16 which feeds a register comprising stages 26-29 for storing the data and parity bits, the stages 26-29 being connected to a parity checking circuit 38 which provides an output pulse on a line 46 if a parity error is detected. The clock signals on lines 12- 15 are supplied via a detection circuit 17 to a register comprising stages 30-33. The subsequent circuitry for one channel only, the "B" data bit channel, is shown, corresponding circuitry for the other channels being provided. The following situation may arise: (1) No parity error and no clock error. If the B digit is a "O", there is no output on a line 45 from the register stage 31,and the channel output 57 indicates a zero. If the B digit is a "1",and "and" gate 49 is opened to produce a "1" signal on the output 57. (2) Drop-out error in channel B. If the missing B digit is a "1", the parity check circuit 38 produces an output at 46, and an "and" gate 47 is opened to produce a "1" output at 57. If the missing B digit is "O", gates 47,49 are both inhibited and a "O" output at 57 is produced. If there is a simultaneous error in two or more channels,an "and" gate such as 59 is opened to produce an indication at 62,that a non- corrected error is present.

Title: Apparatus for and method of drawing off the wort in making beer
IPC: C12C7/14
Filed: 1954-02-09
Abstract: 765,224. Wort. METZ, A. Z. Feb. 9, 1954, No. 3740/54. Class 14(2) Wort is removed from a mash by introducing water upwardly into the mash whilst continuously drawing off the wort from the top of the mash. Water is passed into tub 6 through underlet pipes 10, and a maserating device 58 is rotated at high speed by a motor 71, when the materials to be used are introduced into the tub through trapdoors 87 and 88. On completion of mashing, hot water is led into the tub through the pipes 10, whilst maseration continues, until the quantity of mash is sufficient. Maseration is stopped the trap doors shut and the mash is allowed to settle, after which a screen plate 48 is lowered to dispose the lower ends of siphons 24, 25 below the liquid level. Valves 33, 34 are opened and water runs into the legs 26-which leads to the grand 11-and 27, 28 to fill the siphons, whereupon valve 34 is closed. The top wort is drawn off and as the liquid level falls the screen plate 48 is correspondingly lowered. During this continuous siphoning of the wort a slow speed motor 72 drives the maserating device 58 which gently squeezes the mash. The screen plate 48 is lowered until it presses on to the mash solids thereby increasing the extraction yield. This initial siphoning i.e. water not admitted to the tub during siphoning is optional and is followed by further siphoning in which after more water is admitted to the tub 6 to the desired level, such level is maintained constant by regulating the water intake by valves 20, 21 during this further siphoning. A strainer 35 is mounted on the intake end of each siphon, and a liquid seal is provided at their discharge end.

Filed: 1918-03-07
Abstract: 138,654. Wade, H., (Typograph Ges.). March 7, 1918. Magazines and escapements for type-bar-making machines. In machines having matrices suspended on wires, the wires are arranged one above another in the magazine, and means is provided for turning the matrices into the horizontal position upon entering the magazine section. The arrangement reduces the dimensions of the machine, since the matrices can be disposed horizontally in tiers and with the narrow sides, instead of the wide sides, in the direction of the breadth of the machine. In the arrangement shown in Fig. 1, two groups A, B of inclined wires 1 are arranged at opposite sides of the setting point 2, and the magazine section 5 of each wire is associated with a triangular plate 6 for turning the matrices 3 into the horizontal position. The matrices are moved from the setting point 2 in the direction of the arrows 4, and as each matrix enters the section 5 of the associated wire, the matrix is raised gradually to the horizontal position by riding along the edge 9 of the associated plate 6. To distribute wear of the matrices, the angles 7 of the superposed set of plates in each group may decrease from the bottom plate upwards, the matrices on the upper guides first engaging the edge 9 of the bottom plate and then engaging successively the edges 9 of the upper plates. To prevent the recesses in the. matrices from catching on the edge 9 of the bottom plate 6, that edge is formed wih a broad flange. The matrices are retained in the magazine by stops 10, 13 which may be formed on the plates 6, the stop 13 being arranged at the bottom of a channel 12. The matrices may be released by means of a keyactuated lever 15 which is adapted to lift the bottom matrix to a position above the stop 13, the matrix then swinging downwards. As applied to the arrangement shown in Fig. 3, in which there are two groups A, B of wires which are disposed in four parallel rows 17, 17<a> at the setting point, the triangular plates 19 are arranged so that the cranked matrices on the wires 17 are turned upwards and into the space within the wires, and the matrices on the wires 17<a> are turned upwards and outwards. When the matrices are in position on the plates 19, the matrices on the wires 17<a> are in alinement with the matrices on the wires 17. Machines having tiltable magazines may also be provided with triangular plates such as are described above. In such machines, the usual pusher-arm may be provided for returning the matrices when the magazine is tilted.

Title: Production of heavy water
IPC: C01B5/02
Filed: 1943-03-13
Abstract: Water of increased deuterium oxide content is made in a cycle of steps in which a mixture of deuterium and hydrogen is produced under superatmospheric pressure by reduction, at an elevated temperature, of steam in a fluidized mixture of steam and a finely divided reducing material, the mixture of deuterium and hydrogen is apparated from the reducing material and brought into reaction with liquid water under substantially full pressure of hydrogen production, so that a part of the hydrogen in the water is replaced by deuterium, the hydrogen and any residual deuterium is separated from the water and water of increased deuterium oxide content is withdrawn from the cycle.  The reducing material may be iron or iron monoxide, manganese, or copper and may be regenerated with separated hydrogen. A catalyst such as an oxide or sulphide of molybdenum, chromium or tungsten, or other hydrogenating catalyst is used in the step in which deuterium replaces a portion of the hydrogen in the liquid water.
