Title: Improvements in or relating to thread knotting devices
IPC: B65H69/04
Filed: 1930-06-16
Abstract: 348,431. Knot-tying devices. QUENDOZ, A., 68, Hardturmstrasse, Zurich, Switzerland. June 16, 1930, No. 18372. Convention date, June 20, 1929. [Class 112.] A hand-operated device for tying weaver's knots in which the threads A, a, B, b, are cub to length by scissors 54 previous bo the knotting and subsequently held by clamping heads 46, 45, comprises a slidable clamping jaw 8, a pivotal flap 13 and looping arm 16, 17. The thread A, a is inserted in incisions 21, 23 in the base 1 and recess 15 in the flap 13. Its free end is held by a fixed clamp 73 and its stock by a sliding jaw 8. The thread B, b is inserted in the incision 22 with its free end held by a clamp 71 and its stock by a clamp 72. The knotting operation is commenced by sliding a carriage 33 towards a block 20 which turns down a finger 26 to hold the threads a the point of crossing, operates the scissors 54, 55 by push rods 41 to cut the free ends of the thread to correct lengths and raises clamping heads 45, 46 and push rods 47, 48. The sliding clamp 8 is then moved forward and rocks the flap 13 sidewise and draws the thread A, a out of the groove 15 to form it into a vertical loop as shown in Fig. 6. Continued sliding of the clamp 8 moves the arms 16, 17 which bend the free thread ends raised into a vertical position by the push rods 47, 48 and lay them under the clamping heads 45, 46 as shown in Fig. 14. Further movement of the clamp 8 pushes back the carriage 33 and releases the clamping heads 45, 46 which fall back under the action of springs or cams. The clamp 8 is then retracted which tightens the loop C and pulls out the threads from beneath the clamping heads. The strength of the springs is such that the thread A, a is pulled out before B, b. Alternatively this may be effected by cams arranged to be rotated by motion of the carriage 33. As shown in Fig. 4, the scissors comprise blades 54, 55 which are pressed against each other by a spring and formed with crescentshaped extensions 56, 57. These coact with semicircular portions 58, 59 on a lever 60 to open, and a wedge portion 61 to close the scissors. The levers 60 of each pair of scissors are operated by the forward end of the push rods 41. Fig. 6 shows the details of the carriage 33 for raising the clamping heads, push rods and the finger 26. The finger 26 comprises a tappet shown dotted in its operative position which it assumes when actuated by the lever 28 and full in its inoperative position which it assumes under the action of the counterweight 27. Attached to the base of the carriage 33 by a pin and slot connection 39, 38 is a push rod 37, the forward end of which raises the guide block 44 and with it the clamping heads 45, 46 and push rods 47, 48.

Title: Improvements relating to tractor-trailer hitches
Inventor: MCNEICE JAMES CURTIS
IPC: B60D1/46
Filed: 1953-07-03
Abstract: 745,243. Vehicle couplings. MASSEYHARRIS-FERGUSON (SALES), Ltd., [formerly FERGUSON, Ltd., H.]. July 5, 1954 [July 3, 1953], No. 18428/53. Class 103 (5). A tractor of the type having power lift arms 1, Fig. 1, which can be used also to raise or lower a hitch arm 4, is provided with links 9 the lengths of which may be adjusted in a manner similar to a vernier gauge and are pivoted to extensions 10 of the arms 1, and pin and slot connected toggle links 14, 18, which may be actuated to maintain the hitch linkage rigidly propped in the raised position so that the power lift mechanism can be released. The tractor is also of the type having automatic means for putting the power lift out of action. The link 14 is U-shaped, Fig. 6, and is provided with a spring handle 19 co-operating with a locking plate 19D. In operation, when the arms 1 are raised the hitch 4 rises until a hump 4B thereon contacts a plate 4C which stops the rise just before the lift is automatically cut off. This stoppage occurs when the pins 18A of the toggle lost motion are midway along the slots 14A. Meantime the stem 19A of the handle has engaged the locking plate 19D to provide frictional resistance to ensure that the loose toggles do not move under gravity beyond their inactive aligned position in which the hitch 4 is supported by the linkage 1, 10, and 9. In order now to use the toggle links as a prop, the driver pulls the handle 19 towards the right in Fig. 1, and engages its stem 19A behind the plate 19D, thus moving the toggles over centre to take up the lost motion and permit the stop 20 to abut the casing 7. The power lift may then be released to allow the hitch linkage to drop and rest on the toggle, thus supporting the hitch 4 and the links 2 in a raised position. In order to release the hitch, the handle 19 is lifted and the arms 1 raised. The power lift is then operated to drop the arms 1 and the toggles are moved by the handle 19, and then folded by the dropping movement to the Fig. 1 position. In a modification the handle 19 may be dispensed with and the links allowed to fall into their propping position under gravity. A spring load may be applied to the toggles as an addition or alternative to the gravitational action.

Title: Improvements in or relating to the reaction of alkenes with water and the alcohols so produced
IPC: C07C29/04
Filed: 1951-08-03
Abstract: Mixtures of an alkene and water are subjected preferably in the vapour phase to the action of silent electric discharges to produce alcohols having a larger number of carbon atoms than the initial alkene, e.g. ethene yields 1-butanol, propene, a primary hexanol. Aldehydes and alcohols corresponding to the alkene used are also produced, ethene yielding also ethanal and ethanol. Preferably the alkene contains not more than 5 carbon atoms.  The reaction which may be batch or continuous may take place in the presence of 10 to 50 per cent of hydrogen, 4 to 10 molecules of water being present per molecule of alkene.  Temperatures are preferably below 250 DEG  C., suitably 50 DEG  to 150 DEG  C., and residence times of 1 minute or less are preferred.  Mixtures of alkene and alkane may be employed or mixtures of alkenes, in which case in addition to products containing double the carbon atoms of each of the original alkenes, products containing the sum of such carbon atoms may be obtained.  The silent electric discharge may have a frequency of 50 to 500 c.p.s. and a voltage of 10,000 to 20,000 volts or higher may be used.  According to examples: (1) a mixture of ethene, water and hydrogen is passed in vapour phase through an ozonizer at 80 DEG  to 85 DEG  C. and the reaction products condensed and fractionally distilled to yield 1-butanol, a primary hexanol, ethanol and ethanal; (3) propene and water are passed through an ozonizer at 120 DEG  C. to yield propanal, 1-propanol, 2-propanol and 2 : 3-dimethyl-1-butanol; (5) isobutene, water and hydrogen under similar conditions yield 2 : 2 : 3 : 3-tetramethyl - 1 - butanol, 2 - methyl - 1 - propanol, 2-methyl-2-propanol and 2-methyl-propanal.ALSO:Mixtures of an alkene and water are subjected to the action of a silent electric discharge, preferably in the vapour phase to produce alcohols having a larger number of carbon atoms than the initial alkene, e.g. ethene yields 1-butanol, propene, a primary hexanol.

IPC: B60T13/57
Filed: 1961-05-24
Abstract: 979,419. Fluid-pressure brakes. MIDLAND-ROSS CORPORATION. May 24, 1961, No. 18698/61. Heading F2F. [Also in Division G3] A differential pressure servomotor comprises a housing having a movable wall 17 communicating on one side with a source of vacuum and on the other side either with the vacuum or with atmospheric air pressure under the control of a flexible valve member 19, piston means in a master cylinder 11 acted upon by movement of the wall 17, and a control member 36 which may be manually operated acting on the valve member 19 to cause a pressure change on the movable wall 17, and is characterized in that the rate of movement of part of the valve member is greater than the rate of movement of the control member. In the embodiment shown in Fig. 1, the servomotor is applied to assist a vehicle hydraulic master cylinder braking system 11, 12, 13 and the servomotor parts are shown in the released condition of the brake wherein vacuum is present on both sides 22, 23 of the movable diaphragm wall 17 of the servomotor. Initial movement of the control member 36 in response to effort applied to a pedal 21 moves a valve seat 103 against a flexible valve member 19 to a lap position to isolate the chambers 22, 23 not only from the atmosphere in bellows 56 via inlet 59, 58 but also from each other. At the same time a ring 88 is moved to the left against the radially inner ends 87 of levers 82 and the wall 17 remains stationary, the levers 82 pivot about their radially outer ends and this movement is transmitted to a plate 81 and a rod 18 to actuate the master cylinder piston and apply the brakes. Further movement of the control member 36 applies further movement to the levers 82 and rod 18 and at the same time the valve member 19 is deflected from engagement with its seat 107 to place the valve chamber 98 in communication with the interior of the bellows 56 and allows atmospheric air to enter the chamber 22. The differential pressure created on the wall 17 moves it to the left and the levers 82 are caused to pivot further about their radially inner ends 87 to actuate the plate 89 and the rod 18 further to increase the pressure in the hydraulic braking system. The construction of the flexible, resilient valve member 19 causes its seat part to move at the same rate of speed as the control member 36 but the seat engaging portion pivots about the hinge and moves at a greater speed than the control member 36 to increase the opening movement of the valve means to provide quick response to pedal effort. Specification 979,418 is referred to.

Abstract: 1305057 Verifiers MOHAWK DATA SCIENCES CORP 20 April 1970 [18 June 1969] 18776/70 Heading G4C A verifier system comprises a buffer for storing a block of characters generated by a keyboard. During subsequent operation of the keyboard the keyboard output is compared with the characters in the buffer. Bits representing the result of each comparison are stored to indicate which characters, if any, require correction. When correct the characters are read from the buffer to a magnetic disc or tape store. When a block of characters is fed from the keyboard to the buffer during an Entry mode an error control bit (EC) is generated in respect of each character. Each EC bit indicates whether the corresponding character of the present block is (EC=0) or is not (EC=1) the same as the character of the preceding block which it is replacing in the buffer. The EC bits are stored in a control store. If the operator presses a Skip key space characters are generated until a preset position in the block is reached. If a Duplicate key is pressed the corresponding characters in the buffer are unaltered and the EC bits = 0. Skip and Duplicate operations may be performed automatically. At the end of the block the system passes automatically to Verify mode. The operator rekeys the characters and each character now generated is compared with the corresponding character in the buffer. Where the comparison shows equality any stored EC bit that is 1 is reset to 0. If there is lack of equality the system switches to Error mode. The operator now rekeys the correct character. If the comparison now shows equality the Verify mode is re-entered. However, if there is still inequality this means that the character in the buffer is incorrect. By rekeying the correct character while pressing a special key the system is temporarily placed in the Entry mode, the incorrect character in the buffer is replaced by the correct one and the EC bit is set to 1. Verification then continues but at the end of the block transference of the block to the disc or tape store is prevented until any characters entered during the Correction mode have been reverified. This is done by automatically stepping the circuitry back to the first corrected character, indicated by EC=1, the operator then rekeying the correct character. When the block has been verified or reverified the block is automatically transferred to the disc or taps store. When the store indicates that the block has been received the system reverts to the Entry mode.

Title: Improved washing machine
IPC: D06F37/30
Filed: 1963-05-13
Abstract: 1,027,014. Washing machines. S. B. POPE. May 13, 1963 [May 18, 1962], No. 18790/63. Heading D1A. [Also in Division H2] In a washing machine in which the clothes bowl having a vertical inclined or horizontal axis is adapted to be rotated in one direction for spin drying and in which the bowl, or an agitator co-axial therewith, is oscillated for washing, the drive is effected by a single motor arranged concentrically to the bowl axis. As shown in Fig. 1 the rotor 23 of the motor 24 is directly coupled to the shaft 22 of the bowl 20 within an outer tub 21 and the windings 25 of the stator are controlled by a reversing switch 26 actuated by a cam 27 on the shaft 22. Thus, during washing, after rotation of the bowl through a predetermined angle in one direction the switch 26 is actuated to reverse the motor to provide the required oscillatory movement. For spin-drying the switch 26 is put out of action either by arresting the cam 27 which is driven through a slippable clutch or by electrical switch means Fig. 10 (not shown), so that rotation in a single direction continues. The electrical switch means can at the same time reduce the number of poles of an induction motor so that the speed is increased for the spin drying operation. Such switch means may be actuated by a relay under control of a timer of an automatic machine. In Fig. 2 (not shown), the rotor of the motor is directly coupled to an oscillatory agitator 31 in the bowl 20 and the bowl is driven in one direction for spin-drying through a spring coil clutch 30.
