Filed: 1974-03-06
Abstract: 1437904 Shrinking fabrics CLUETT PEABODY & CO INC 6 March 1974 [26 April 1973] 10058/74 Heading D1S A fabric web 5 is longitudinally compressively shrunk by feeding it between a belt 23 of elastomeric material and a cylinder 30 having a low frictional surface resistance, the belt 23 being wrapped partially around the cylinder 30, the tension of the belt 23 and the amount of wrap contact between the belt 23 and the surface of the cylinder 30 being selectively variable. As shown in Fig. 1, a fabric web 5 is unwound from a roll 4 by rolls 6 and fed by rolls 7 to a scray 8 from which it passes between swivel tension bars 9, over a sky roll 10, through a fabric guider 11, around an idler 12, around rolls 13a, 13b and an input measuring roll 13c, through a conditioning chamber 14 in which both faces of the fabric are exposed to moisture, e.g. steam, over a weft straightening device 15, around one or more heated drying cans 16, over rolls 18, 19, over a scrimp bar 19a, through a compressive shrinking unit 17, over rolls 20, 20b, 20a, through a felt belt drying unit 40, over rollers 41, 42, 43, over a cool roller 44, over rollers 46, 47, 48 in an air cooling unit 45, around roller 49, between feed rolls 50 into a scray 51, over swivel tension rolls 53, over sky rolls 54, through fabric guiders 55, around a roll 56 and is wound on a roll 57 by rollers 52. The rolls 13c, 20b are interconnected by tachometer generators 21a and to a visual metering device 21b whereby an operator may make any fabric feed adjustments necessary to ensure the desired amount of shrinkage. The unit 17, Fig. 2, comprises a highly polished heated drum 30 and a rubber belt 23 extending around a nip roll 24, an adjustable tension and wrap roll 25 and rolls 26. The distance between the roll 24 and the drum 30 is adjustable by a mechanism 31 comprising two rotatable screws 32 engaged by internally threaded yokes 33 connected to bars 34 including journals for the roll 24. A belt tensioning screw 60 is rotatably connected to a lever 61 and to the bearing of the roll 25 through an internally threaded journal 62. Movement of the roll 25 along an arcuate path to increase or decrease the amount of wrap of the belt 23 around the drum 30 is effected by a screw 63 through a journal 65 and the screw 60. Water spray devices 67 effect cooling of the belt 23 and rolls 68 remove water or moisture from the belt as it approaches the roll 24. Preferably, the belt 23 is reinforced by longitudinal threads.

Cupping.-In draw presses for sheet metal having the die on which the draw is performed provided with a movable pressure ring on which uniform pressure is maintained during the drawing operation, the pressure ring is actuated by a cam which is oscillated by rack-and-pinion mechanism from a moving part of the press. The pressure ring d<1>, Fig. 1, is connected by pins d<2> to a platform d<3> bearing on the buffer e which is supported by a member j<2> constrained to move vertically and carried by a yoke l pivoted in links l<1>. A nut l<2> threaded on the member j<2> bears on the yoke l. The pressure of the buffer is varied by altering the position of the nut. The member j<2> is attached to one end of a bell crank lever j', which is rocked by a cam j on a shaft i<1>. A pinion i on shaft i<1> meshes with a pinion f<1> in gear with a rack f, which is connected by a rod g<1> to a crank disc f<2> on the main driving shaft of the press. The outer ring d<4> of the lower die is for cutting the blank before the drawing operation takes place by engagement with the edge c<2> of the upper die. In a modification, Fig. 3, in which the drawing operation is performed in two stages, two pressure rings n, n<1> are provided, actuated by cams x, x<1> respec tively. The cams are relatively adjustable in order to determine and vary the point at which the first draw ends and the second begins. The edge n<10> of the ring n is preferably curved or inclined.

Abstract: 996,954. Automatic volume control circuits. TELEFUNKEN PATENTVERWERTUNGS GESELLSCHAFT. March 16, 1962 [March 10, 19611, No. 10133/62. Heading H4R. In an arrangement for reducing the time constant of indirectly heated thermistors used in level control in multi-channel carrier frequency communication systems in which the thermistor heating current is variable in steps. A time controlled switching device is provided which operates, on an increase or decrease in heating current, to switch in for a short time an excessive increase or decrease respectively in heating current to enable the thermistor to attain its required temperature quickly. Fig. 3 shows a system in which the heating current through a thermistor heating coil RH is digitally controlled by a device St via a setting device EV. If the heating current is to be increased by one step the device M1 is actuated by St simultaneously with the operation of device EV. Switch S1, which may be a form of monostable multivibrator, is operated for a short time during which the connection of potential 0 to resistor R1 caused an extra current flow through the thermistor heater RH and causes it to reach its required operating temperature rapidly. Similarly if a decrease in current is signalled to EV the device M2 is actuated and the current in the thermistor heater is excessively reduced for a short time. Alternatively the same switch may cause the excessive increase on an increase in current and the excessive decrease on a decrease in current Specification 992,663 is referred to.

Title: Improvements in or relating to ingot moulds
IPC: B22D7/10
Filed: 1939-04-03
Abstract: 522,086. Moulds. CHATWIN, J. (Thyssen Hutte Akt.-Ges., A.). April 3, 1939, No. 10326. [Class 83 (i)] Mould materials.-The rate of cooling of a casting in an ingot or a centrifugal metal mould is decreased by lining the mould, wholly or in part, with mould material having grains of varying size, sintered to increase its strength. The material should have 40 per cent. with grains between 4 and 2 mm. in diameter, the rest being under 0.85 mm. or 40 per cent. between 2 and 0.85 mm. and 20 per cent. under 0.85 mm. A mixture of materials having different thermal expansions may be used so that during drying and in use the lining does not expand or contract relative to the mould, e.g., 75 per cent. burnt chamotte, 13 per cent. fresh clay and 12 per cent. quart with a little water, dextrine, or sulphite liquor. Cohesion may be improved and cooling increased by embedding iron wires, rods, or rings in the lining, 3, e.g., integral or screwed rings 7, Fig. 3, or 9, Fig. 5. As the lining 3 at the ends of the mould 1 is subjected to the most wear it may be replaced by an integral shoulder 6, Fig. 2, or a screwed or loose iron ring 5 or a strongly burnt refractory ring.

Title: Mortice lock with automatic shooting of the bolt
IPC: E05B59/00
Filed: 1932-04-11
Abstract: 404,324. Latches. MARX, R., 70, Solingerstrasse, Foche, Solingen, Germany. April 11, 1932, No. 10330. [Class 44.] A latch bolt 3, withdrawn by an ordinary follower 17, acts also as a slam bolt to release a further bolt 10 to allow the latter to be shot by its spring 13 when the door into which the latch is morticed is closed. When the door is slammed, a lever 4 pivoted at 5 in the head of the latch 3 is depressed against a spring, so that its tail 6 lies over a lever 7 to rock the latter and move a slide 9 downwards as the latch moves inwards, thereby disengaging a pin 11 on the slide 9 from a shoulder 12a of a slot 12 in the bolt 10. When the latch 3 is withdrawn by the follower 17, the tail 6 of the lever 4 passes behind the lever 7 and the bolt 10 is unaffected. The bolt 10 is withdrawn from the outside of the door by a lock follower which raises the slide 9 by engagement with a projection 15, further rotation of the follower causing it to engage with a cam surface 16b on a lever 16 to withdraw the latch 3. The lock follower may be controlled by a cylinder lock. The two bolts 3, 10 may be withdrawn from the inside of the door by a second lock follower or by a handle follower.

Title: Spooling machine system and method to wind multi-layer spools particularly for wire tape and the like
IPC: B65H54/28
Filed: 1975-03-13
Abstract: 1472038 Method and apparatus for forming side-by-side windings DRAHTWARENFABRIK DRAHTZUG STEIN KG 13 March 1975 [13 March 1974 (2)] 10615/75 Heading D1J The invention relates to a method and apparatus for making packages with closelywound convolutions.  The turns are laid in a side-by-side manner on a take-up spool 3, Fig. 1, by causing the material 1 being wound to approach the plane of winding at an angle α such that the turn being wound on presses against the previously wound turn, the angle α being maintained constant over an intermediate range 7 of the take-up spool and being allowed to reduce to zero in end regions 6 and 8 as the yarn approaches the flanges 5 of the spool 3, and to build up again to α in the opposite direction as the yarn turns reverse their traverse and move away from the end flanges, the angle α reaching a maximum and being maintained constant over the intermediate range 7. A control circuit for the process is described with reference to Fig. 1. It includes:- (a) a size gauge 9 giving a signal representative of the transverse size of the material 1 being wound; (b) a width sensor 9 determining the size of the spool 3 and hence the sum of the dimensions 6, 7 and 8; (c) a manual spool width data input unit 14 for use if the sensor 9 is not to be used; (d) a sensing element 20 for determining the angle α, the element 20 being coupled to a transducer 22 from which a signal representative of the angle α is emitted; (e) a tachometer 28 coupled to the shaft 4 of the spool 3; and (f) a potentiometer 36 in a feedback system determining the instantaneous axial position of the shaft 4. The potentiometer may be replaced by a digital position indicator, such as, for example, an electro-optical or electromagnetic pulse disc or strip. All of the above sensors are interrelated and controlled by a command unit 25, comparator 24, servo amplifier 27, traverse control circuit 19, α-computer 16 and other circuit elements 10, 13, 30. In Fig. 1 it is the spool 3 that is reciprocated. It is within the scope of the invention for the spool to remain axially stationary and for a feed mechanism 2 and the sensing element 20 to be traversed. Fig. 2 (not shown) illustrates a piston-andcylinder operated traversing mechanism. Fig. 3 (not shown) illustrates a traversing mechanism utilizing a drive screw requiring reversal of direction of rotation for reversal of traverse, the threaded spindle having its threads in the form of ball races.

Filed: 1944-06-02
Abstract: 587,278. Brick-sanding machines. JOHNSON, J A., and WALKER, F. June 2, 1944, No. 10631. [Class 87 (ii)] In a sanding-machine of the type in which sand is caused to impinge upon bricks by means of compressed air blowers, the blowers are self contained, electrically driven and are connected to the brick feeding apparatus so as to form a single unit with it. A double endless belt 27, 27 runs over pulleys 22, 23, 24, 25 and a single belt over pulleys 30, 31. These belts are arranged to overlap in such a manner (Fig. 2) that bricks 17 can be passed from one to the other. As the bricks pass through a cylindrical encasement 1 the upwardly directed nozzle 16 of a blower 11 sands the underside of the bricks between the double belts 17, 17 and four other blowers (Fig. 3) 11 sand the end portions of the underside and the tops and sides. Sand is supplied by pipes 9 from a hopper 8 to the bottom of the encasement 1 whence it passes through inlet pipes 12 to the blowers 11. These inlet pipes 12 have extensible ends. The Provisional Specification describes also a sanding machine in which a column of clay passes directly from a pug mill into an encasement where it is sanded before individual bricks are cut from it.

[Also in Group XL (a)] Control rods in a nuclear reactor are adjustable along vertical paths extending parallel to each other and arranged in groups forming concentric loops, the groups being raised successively starting with the outermost group and working inwards. Each rod is moved by a motor PM the motors raising the rods of the first group being coupled together and fed by switches R1. A four-position switch CSWO controls the raising and lowering. When this switch is moved to the US (up slow) position a clutch USC causes a transmitter coil R to be driven by a continuously rotating motor DM so that the motor PM is driven by pulses from coils XO, YO through rectifiers and the switches R1. On reaching the limit of travel of the rods of the first group a limit switch LS2 is closed and a cam controller CCO changes the switches so that motors of the third group are next energized. Clutches DSC, DFC provide for lowering slow or fast. When lowering the limit switches LS1 operate the cam controller CCO to change from, for example, group 7 to group 5. The apparatus illustrated in Figs. 4 and 5 applies only to the odd groups of control rods, the even groups being started when the previous odd group is half-way through its travel.
