Title: Improvements relating to the construction of boots or shoes
IPC: A43B3/10
Filed: 1931-10-08
Abstract: 385,687. Boots &c. ; sewing &c. LEE, A., 67, Queen's Park Parade, Northampton. Oct. 8, 1931, Nos. 27991/31 and 12990/32. [Classes 17 (ii) and 112.] An improved method of constructing a shoe which dispenses with the usual insole by turning in the edges of the vamp or upper consists in a composite vamp 1 and apron 9, Fig. 1, so shaped as to form a pocket extending under the foot. The sole or middle sole is attached to the vamp preferably by stitches. The vamp portion 1, Fig. 2, has the edges 2, 3 gathered together to form a T-shaped line of stitches 4, Fig. 4, under the foot. After stitching, the vamp 1 may be moulded on to a last before or after attachment of the quarters 6. The vamp 1 may have a middle sole doubly sewn to it at 8, Fig. 4, and the heel may be either riveted on or sewn. The parts 1, 9 are preferably bevelled, Fig. 5b, and stitched at 10 so that the stitches do not pass to the inside. A shoe may be made more waterproof by employing a double vamp, Fig. 5c. The second vamp may be turned outwards in the Veldtschoen manner. In a modification, Fig. 8, the vamp 14 has an inner piece 15, Fig. 11. This portion 15 forms the equivalent of an apron only it is placed at the bottom of the shoe. The part 14 may be skived and the part 15 attached by adhesive or by sewing. Where sewing is employed the stitches preferably pass from the outside of the major portion 14 into but not right through the same, then through the edge of the portion 14 into the edge of the part 15, then up to the outside face of the latter. The stitches do not appear inside the shoe. The toe part 17, Fig. 8, of the shoe is attached in any appropriate manner. The vamp may be double and the parts may be connected by latex. A preferred form of stitching employed near the rear ends of the joint between the apron 9 and vamp 1, Fig. 1, is shown at Fig. 12. The stitches are formed of two waxed threads 18, 19 the ends of which are 20, 21. The thread 18 secured at 20 passes through the vamp 1 and quarter 6 and is then led transversely across the leather outside and passed back through the quarter, apron 9, and vamp 1 into the quarter 6. It then comes out of the leather of the quarter upon the outside and runs longitudinally at 22, passing into the quarter again but without passing right through it, and comes through the front end of the same and enters the vamp 1 at 23. It then passes into the vamp 1 as a stitch 10, as at Fig. 5b. It then comes to the outside of the apron at 24 and runs longitudinally parallel with the seam outside the leather, passes into the apron at 24 and across the seam and out of the vamp 1 at 25 across the seam outside then back into the apron 9 at 24 and out of the vamp 1 at 25. It then passes longitudinally outside to 26 where it again passes into the vamp 1, coming out of the apron 9 at 27, running to 28 entering the apron again. The stitching may be performed by hand with a curved awl and two opposed bristles. If machine stitching were employed, one needle only would be used.

Title: Improvements relating to radix conversion apparatus for digital code signals
Inventor: FROGGATT ROBERT JUSTIN
IPC: H03M7/06
Filed: 1956-09-14
Abstract: 869,134. Digital electric calculating apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 16, 1957 [Sept. 14, 1956], No. 28103/56. Class 106 (1). Radix-converting apparatus comprises more than one adding device to which binary-coded signal groups are applied, a plurality of paths each including column-shifting means for feeding back the running totals from the outputs to the inputs of the adding devices, and gating means for selectively controlling the passage of signals through the feed-back paths so as to convert the signal groups into pure binary code. Binary-coded decimal, ú s. d., or other non- uniform signal groups in series-mode, the decimal &c. digits being in decending order of magnitude, are fed to a first adder 1 on line 3, the result being fed to a second adder 2 and then to a register 5 having a delay equal to a minor cycle (i.e. to the passage of one group). By feeding the binary result signals back to the adders 1, 2 via delay elements of one (6), two (7) and three (8) units, multiplication by two, four and eight respectively is achieved in time with the arrival of the next binary group on line 3. Thus, by opening gates 9 and 11 the signals fed back from the register 5 to the adders are multiplied by ten; similarly, in the course of ú s. d. conversion, multiplication by twelve is achieved by opening gates 10 and 11. In this way the decimal, ú s. d. &c. amount is reduced to pure binary and the result stored in the circulating system including the register 5 which may be a thermionic valve shift register, an acoustic delay line, or a magnetic core shift register. An extra feed-back path without delay may be provided for purely storage purposes.

Title: Device for indicating the amount of the displacement of a slide
IPC: H03M1/00
Filed: 1963-07-17
Abstract: 986,220. Electric selective signalling. M. HENSOLDT UND SÍHNE, OPTISCHE WERKE A.G. July 17, 1963 [July 20,1962], No. 28372/63. Addition to 931,042. Heading G4H. The invention relates to a position digitiser, and is primarily concerned with preventing errors consequent upon zeroising of number-indicating tubes used to indicate the result. In Fig. 1, a brush 6 earths one contact area of a millimetre slide 5 thereby energizing the corresponding cathode of a number-indicating tube 1 via a zeroising switch 4 which enables the leads to be interchanged and a reversing switch 3 which enables counting to be done in either direction. The leads of tube 1 are connected to a switch 7, ganged to zeroising switch 4 and which connects each lead to one of two brushes 8 1  and 8<SP>1</SP> 1  on separate centimetre slides 9, 9<SP>1</SP>. The contact areas of slides, 9,9<SP>1</SP> are connected to cathode leads of number-indicating tube 10 via a zeroising switch 4<SP>1</SP> and a reversing switch 3<SP>1</SP>, areas connected to the same cathode lead in the two slides 9,9<SP>1</SP> being mutually displaced by one contact area, as indicated by the ringed numbers in Fig. 2. Thus which of the brushes 8 1 , 8<SP>1</SP> 1  is used depends on the reading in tube 1 and the setting of millimetre zeroising switch 4 (via switch 7), thus ensuring that the reading in tube 10 subsequent to zeroising does not change until a full centimetre has passed. The arrangement may be extended to higher decimal orders. Fig. 4 (not shown) shows a modification in which in order to avoid bridging of the gaps between contact areas due to wear, alternate areas in slides 9,9<SP>1</SP> are laterally displaced, each slide now having two brushes connected in parallel.

Title: Liquid ring pump
IPC: F04C19/00
Filed: 1951-12-05
Abstract: 700,487. Liquid-ring pumps. NASH ENGINEERING CO. Dec. 5, 1951 [Feb. 15, 1951), No. 28509/51. Class 110 (1) A liquid-ring gas pump comprises a rotor which runs in a lobed pumping chamber having a conical inner boundary, and a lobe of progressively increasing depth from the end at which the diameter of the conical inner boundary is greatest towards the end at which it is least. In the pump shown in Figs. 11, 17 and 18, comprising a rotor 3c coacting with ported cones 4c and lobes 10c, the lobes are of conical form, whereby the variation, along the axis of the pump, of the rotor displacement volume is matched by a corresponding variation of the displacement volume of each lobe. This minimizes the formation of parasitic currents, loss of liquid through the inlet and outlet ports and other adverse effects which would occur if the lobes were of conventional form. The radius of each lobe increases from Rc to Rc2, as shown, the corresponding offset of the axis of the lobe with respect to the axis of rotation increasing from Oc to Oc2. Instead of increasing, the offset may decrease or be constant. Alternatively, the radius may be constant while the offset increases. In the embodiment shown in Fig. 19, each lobe 34 is lopsided, being formed by an arc 37 of radius Rd1 merging with an arc 39 of radius Rd2. The axis of the lobe is of increasing offset with respect to the axis 33 of rotation, so that the centres shift progressively from 41 and 42 at one end of the lobe to 38 and 40 respectively at the other end. All these constructions incidentally give a tapered form to the lands 7c, Figs. 17 and 18, whereby each rotor blade crosses the boundaries between the lobes and lands progressively instead of abruptly, thereby reducing noise, vibration and cavitation. Specifications 379,891 and 462,208 are referred to.
