Abstract: 1433481 Insoles for shoes BRITISH UNITED SHOE MACHINERY CO Ltd 26 March 1973 [25 March 1972 7 March 1973] 14107/72 and 11092/72 Heading A3B [Also in Division B5] A shoe insole comprises a non-woven bonded fibre mass having a greater density and rigidity at a rear portion of the insole than at a fore part portion thereof. The insole may be cut from a material produced by assembling a first non-woven bonded fibre batt with at least one further non-woven bonded fibre batt of smaller area than the first batt and superposed thereon and subjecting the assembly to heat and pressure to bond the batts together and consolidate them in the region in which they are superposed so that they have greater density and rigidity in that region than does the first batt in the region thereof on which the further batts are not superposed. Alternatively the layers of non-woven bonded fibre batt of different size may be cut to shape prior to bonding them together to form the insole. During heat and pressure treatment the assembly may be shaped to impart thereto a shape corresponding approximately to the contour of the bottom of the foot. The smaller layers may also comprise one or more sheets of thermoplastic material, e.g. polyvinyl chloride. At least one of the outer surfaces of the insole may comprise a layer, e.g. non-woven or woven fabric or paper, to which a hot melt adhesive will adhere. Heat and pressure may be applied by use of a high-frequency welding press, a heated platen press, rollers or heated moving belts. The non-woven fibre layers may comprise nylon and viscose rayon fibres and the bonding agent may be a vinyl chloride copolymer, optionally in admixture with a carboxylated nitrile rubber, or a plasticised styrene/butadiene copolymer.

Title: Improvements in or relating to firearms and magazines therefor
IPC: F41A9/68
Filed: 1942-08-14
Abstract: 573,435. Cartridge magazines. VESELY, J. Aug. 14, 1942, No. 11409. [Class 119] A firearm fitted with a magazine having two or more compartments, such as 7, 8, arranged one. behind the other, is provided with means for retaining the upper cartridge 27 in compartment 8 until compartment 7. is exhausted, and with means for actuating the retaining means so that it acts on each cartridge in compartment 8 in succession while the previous cartridge is being fed towards the breech chamber. In the form shown, the cartridge 27 is retained by a finger 25 projecting from a tubular boss which is mounted on a spindle 21. This spindle and a further spindle 20 are mounted in a chamber 19 of the firearm, the spindle 20 carrying a spring-controlled tubular boss 34 tending, under the action of the spring 37, to rotate in an anti-clockwise direction in Fig. 4. The boss 34 carries a detent 32, the under face of which is so shaped that when it is made to bear, under the action of spring 37, on a similar face at the end of a lever 29 integral with the finger 25, it forces the finger to move into the cartridge-retaining position shown. The finger when so forced is positively held by the engagement of the end face of detent 32 with the curved face 31 of lever 29. In operation, a projection 41 extending from the feeder plate of the front compartment through a slot 42 in the magazine wall rotates the boss 34 against the action of its spring when the front compartment is exhausted of cartridges, thus freeing the finger 25 and enabling the cartridge 27 to be moved into the path of the breechblock. As each cartridge is fed from compartment 8 towards the breech chamber, it depresses the feeder plate of compartment 7. This action depresses the projection 41, thus enabling the devices in the chamber 19 to move, under the action of spring 37, to the cartridge-retaining position shown in Fig. 4. Specifications 573,429, 573,434 and 573,458 are referred to.

Abstract: 455,227. Planting-machines. FERGUSON, C. S. R., 119, Dudley Road, Whalley Range, Manchester. April 15, 1935, Nos. 11539 and 24220. [Class 6 (i)] In a machine for planting potatoes &c. comprising a reservoir 6 from which the tubers are fed singly by a conical rotary floor 7 mounted on a vertical spindle 8, the outlet of the reservoir is controlled by a feed-drum 23 mounted on a spindle 24 arranged radially of the vertical spindle 8, the drum being provided with pockets each of which receives a single tuber, fed into it from the end of the drum, and delivers it to apparatus which deposits it in a furrow made by a ploughshare on the machine. The machine frame 1 is mounted on a front swivel wheel 4 and laterally adjustable rear wheels 3, which may have V-shaped rims to run on ridges. The spindle 8 is driven through a countershaft 13 from the wheels 3 or from a dibbler wheel 19 running in the furrow. The drum 23 is driven by a chain from the shaft 13. A wall 22 in the reservoir or hopper 6 is provided with an outlet 21 furnished with a spring- controlled door 30. The end of the feed-drum 23 has its periphery 23a inclined as shown to facilitate the entry of the tubers into the pockets 29. The tubers fall on a rotary table 31 having an inclined corrugated surface which feeds them to an outlet 33 in a fixed central part 32, from which they fall on an oscillating conveyer 34. The table 31 is driven by a pinion 37 on the shaft 13 gearing with an annular gear wheel 36. The conveyer 34 is supported by a link 38 and connected by a link 39 to a crank 40 on a shaft 41 driven from the shaft 13. A trap 43 and a sliding conveyer floor 45 are connected by link-work to the crank 40 and are arranged to deliver the potatoes one at a time to a conveyer wheel or band 51, which drops them in the holes made by the dibbler wheel 19. Inclined furrow-closing discs 62 may be raised by means of a lever 61 and the dibbler wheel 19 by means of a lever 59 &c., the axle 18 moving in a slot 56. Specification 422,356 is referred to. According to the second Provisional Specification the reservoir may be a spritting box having one side adapted to be let down or opened.

Title: A method of and an apparatus for connecting two webs in register
IPC: B65H19/16
Filed: 1966-03-16
Abstract: 1,105,357. Feeding webs. SIEMENS-SCHUCKERTWERKE A.G. 16 March, 1966 [18 March, 1965], No. 11592/66. Heading B6B. [Also in Division G3] In web-roll changing apparatus, where the peripheral speed of the replacement web-roll 3 is matched with the speed of the running web 1 by a system including two tachometers 4 and 8 and a regulator 5, the output of which influences the armature voltage of a direct-current motor 7 driving an endless belt 6, the pre-printed webs are registered before splicing. With the speeds matched, there is first stored in a length counter LZ a value (pulses emitting from a pulse generator 10, 11) corresponding to the peripheral distance between register marks P1 and P2, known as the register length L, Fig. 1. This occurs during a single revolution of the web-roll 3, denoted by the period A ,in Fig. 1. At the beginning of the period B in Fig. 1, pulses I supplied by the pulse generator 10, 11, pass to the forward counting input, denoted by the " + ", of a bidirectional pulse counter IZ. Each time the reading of the pulse counter reaches that of the length counter LZ, the reading of the pulse counter IZ is reset to zero by the output signal of a coincidence circuit 21 through a conductor 22. At each revolution of the web-roll 3, a pulse from register mark P1, emanating from a scanning device 14, passes through an evaluating circuit 19 to the input of a revolution counter UZ and increases the reading of this counter. After a particular number of U roll revolutions the counter UZ gives an output signal u, Fig. 2, after which the process indicated by the period C, Fig. 1, commences. The signal u prepares a coincidence circuit 23 through a bi-stable trigger stage 25 and changes the pulse counter IZ for backward counting. Pulses I now received by the pulse counter thus affect a reduction of its reading R remaining at the end of the period B. When the reading reaches zero, the counter is reset to forward counting and from this instant onwards, the successive subtraction of the valve L takes place in exactly the same way as during the period B. In addition, at a coincidence between the readings of the counters LZ and IZ, there appears at the output of coincidence circuit 23, a pulse S which is applied as an actual value signal to a register regulator 17. The desired value signal of the latter is the pulse train which is supplied via a device 15 scanning the register marks on the running web 1. The regulator 17 influences via conductor 27, in a phase regulation sense, the speed regulator 5, so that the webs are registered at the end of the period C after U revolutions, when there appears at the output 28 of the counter UZ a signal which produces a splicing order.
