The nip of a pair of adjustable rolls 2 is divided by partitions 7 into three zones, to the outermost ones of which rubber pieces are fed by endless conveyers; the rubber sheet thus formed passes between one roll and a pair of adjustably spaced cutter discs 27 whereby a rubber web 33 is out from the sheet and removed by a conveyer 34; the remaining separated parts of the sheet pass over a bank of rollers 32, the axes of which are adjustable, arranged generally parallel to the rolls, which guide the parts back to the roll nip. The partitions and rollers 32 are supported by an assembly, pivoted at 4, which can be removed from adjacent the rolls by an hydraulic cylinder 16. A roller 10 over the middle zone engages the rubber in that zone and operates, through linkages 12, 13, means whereby the axes of the rollers 32 are adjusted to control the direction of feed of the two separated sheet parts relative the three zones. A web cutting and jointing unit 15 is supported by the pivoted assembly, and automatically cuts off that length of the web 33 which builds up when the conveyer 34 is temporarily halted, and to rejoin the web before the conveyer is restarted. The unit includes a fixed and a moving knife associated with sealing members, between which the web hangs when the conveyer stops. The cut-off web portion is returned to the roll nip.

Title: One-handed keyboard
IPC: G06F3/023
Filed: 1976-08-26
Abstract: 1500674 Selective printing INTERNATIONAL BUSINESS MACHINES CORP 26 Aug 1976 [6 Oct 1975] 35582/76 Heading B6F [Also in Division G4] A one-handed keyboard comprises a group of finger keys arranged in at least two adjacent rows for operation by the fingers of one hand, the finger keys being spaced closely to each other to enable each finger to actuate at a single finger position one, two or four adjacent finger keys, switches actuated by the keys feeding a register feeding a finger position decoder circuit (which selects subgroups of signals each corresponding to keys actuable at a respective finger position, and converts each subgroup to a finger position signal) feeding a character generator. Keyboard layout and keying possibilities.- Fig. 3-1 shows a right-handed keyboard with 4 thumb keys and a 2 x 5 array of finger keys. The thumb can actuate none, any one or any two adjacent ones (simultaneously) of the thumb keys to select one of three alphabets, case, space, reversal of character order and certain combinations of these. All the fingers can be used simultaneously, each actuating no finger key or a single key or two horizontally-adjacent keys or two vertically-adjacent keys or a 2 x 2 array of adjacent keys, to select a character with each finger used. A "special chord" push-button and a "special word" switch enable, in the "load" positions, a special chord and a special word to be entered on the keys, respectively. With the push-button and switch in the "use" positions, entry of the special chord on the keys causes output of the special word rather than the characters which would normally result from actuation of those keys. Modifications.-There could be 6 finger keys per row on the keyboard, or 3 rows of finger keys. An extra thumb key could be provided, or two rows of thumb keys. The functions of thumb and finger keys could be interchanged to some extent. More than one special chord could be in use. Chinese characters could be typed, using one simultaneous keyboard entry per character.

Title: Hat brim curling machine
IPC: A42C1/06
Filed: 1937-12-28
Abstract: 487,036. Hat-brim curling-machines. CASSE, M. Dec. 28, 1937, No. 35882. Convention date, Feb. 17. [Class 63] [Also in Group XXII] In a machine for curling hat brims, the hat is disposed with its crown downwards and its brim upwards ; water or steam is supplied to what is, normally, the lower face of the brim, and a type of oval lathe mechanism, known per se, is used in which the tangent to the oval at the point of operation of the tool is constant and coincides with the tangent to a circular tool. The hat 1 is retained in a pot 2 by a tapered member 4, the base of the pot engaging studs 7 on a plate 6 keyed to and slidably adjustable on the top face of a cylinder 8 internally toothed to engage with pinion 21 carried by an eccentric bearing in a plate 14 pivoted at 15 to a plate 16 slidable on a frame 18 itself slidably adjustable on a casing 20. The frame 18 carries the hub 27 of a worm-wheel 128 driven by a worm 129 through a clutch and a pulley 32. The hub 27 has an offset portion 26 carrying a screw 28 engaging the bearing of the pinion 21. Adjustment of this screw determines the eccentricity of the oval. A second gear on the shaft of the worm 129 drives a shaft 49 carrying at its upper end an interchangeable curling wheel 55 co-operating with an iron 57 heated by steam, hot air, or electricity. A pipe 166 delivers steam or water or both to the brim. A screw 60 determines the height of the iron. The iron is mounted on a lever 59 pivoted at 61, and is urged against the work by a spring 62, a stop 63 being provided. For retracting the iron, to permit change of work, a treadle rod 46 is connected to the lever 59. This rod also engages an arm 45 for withdrawing the clutch. A pivoted stop 65 enables the iron to be held away from the work. The tangent to the circular tool 55 at the operating point is also the tangent to the hat ; and, if the pot 2 is concentric with the cylinder 8, the curls at the front and rear of the hat are equal. If these axes are eccentric an unequal curling of the front and rear parts of the hat will be obtained, e.g. for enabling the front to be turned down. The adjustment for size of hat is made by sliding the casing 18 on the casing 20 towards or from the iron.

Abstract: 369,202. Steering ships. HARDY, R. J. and SOC. DES ETABLISSEMENTS H. LEPAUTE, 19, Rue Desnouettes, Paris. Dec. 3, 1930, No 36499. Convention date, Dec. 4, 1929. [Class 114.] Relates to improvements in radio directionfinding apparatus in which a stroboscopic device rotates synchronously with h a receiving frame aerial and is illuminated by the amplified current from the aerial. The Specification as open to inspection under Sect. 91 (3) (a) comprises also apparatus for automatically positioning a rudder according to the direction of incoming sounds or radio waves. For the automatic steering of ships towards a radio transmitter a rotating directional aerial system carries a disc F bearing a slot i under which are two photo-electric cells e1, e2 one of which is illuminated by the lamp T operated by the signals if the direction is incorrect. The cells actuate relays B1, B2 respectively and correct in one direction or the other as required, the setting of the rudder g through a controller y and servomotor Sm. For determining the direction of a source of sound, for instance a submarine source, a rotating subaqueous receiver with directional properties replaces the directional aerial system, and with apparatus similar to that of Fig. 9 (Fig. 12 (cancelled), not shown) a vessel may be steered towards a source of sound. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in hydraulic power transmission systems such as hydraulic brake systems
IPC: B60T11/16
Filed: 1932-12-28
Abstract: 415,699. Hydraulic transmission of power. HYDRAULIC BRAKE CO., 84, West Hancock Avenue, Detroit, Michigan, U.S.A. Dec. 28, 1932, No. 36663. Convention date, Dec. 30, 1931. [Class 69 (ii).] The master cyclinder of a hydraulic brake or other hydraulic transmission system is provided with a rearward extension of smaller bore in which slides an extension of the piston so as to form for the cylinder a fluid seal that is under pressure during the return stroke of the piston. The master cylinder 2 has a rearward extension 16 in which slides an extension of the piston 9 which forms with the extension 16 an annular fluid-seal chamber 19 that communicates with the usual reservoir by passage 26 and pipe 6. The piston 9 is chamfered at the end to form an annular space 27 which communicates with the passage 26. Passages 28 are formed through the piston against which the cup washer 10 with axial grooves 29 is seated by the spring 21. Non-return valves 22, 23 acting in opposite directions of fluid flow serve to maintain a pressure above atmospheric normally in the pipe lines 30 and the brake cylinders connected thereto. The piston is forced inwards to apply the brakes by a pin 11 and lever 12. The return movement of the piston, effected by the spring 21, is faster than corresponds to the return of fluid through the pipe lines so that liquid flows from the rear of the piston to the forward part of the cylinder through the passages 28 and past the cupwasher 10. Further, since the bore of the extension 16 is less than that of the main part of the cylinder 2 a part of the fluid displaced by the piston 9 at the rear thereof is forced into the pipe 6 through the passages 26, 25, and since these passages are small, a pressure is created in the chamber 19 which precludes the entry of air into the system past the gasket 20. In a modification the restriction of the passage for the return of the fluid is effected by a disc valve disposed in the boss 7, which is seated by the back flow of the fluid so as to permit flow only through a small aporture in the disc. When the piston is fully returned, the port 25 is uncovered to the forward part of the cylinder 2 as shown to permit the return of the excess of fluid in the system. The pipe line 20 is shown connected to a brake actuating cylinder containing a pair of pistons engaging the shoes of an internal-expanding brake.
