Title: Improvements in hem-stitching machines
IPC: D05B3/02
Filed: 1936-01-31
Abstract: 456,203. Sewing-machines. ANCIENS ETABLISSEMENTS R. CORNELY & CIE, 87, Faubourg St. Denis, Paris. Jan. 31, 1936, No. 2982. Convention date, Feb. 7, 1935. [Class 112] The punch situated between the pair of laterally vibrating needles usual in hemstitching machines is suppressed and replaced by a punch in advance of the needles, and, for thick fabrics, an auxiliary piercer or shaper behind the needles. The corners of the holes may be pulled square by anchoring the corner stitches of a hole opposite adjacent holes, Fig. 10, by a modified backward-and-forward feed. In operation, the needles 2, 3 descend with their points together into the hole C in the fabric made during a preceding stage by the main or fore piercer 4, which, at this stage, prepares the next hole D. The needles are moved apart laterally in the hole, Fig. 19, and form the corner stitches c<1>, c<2>. As the needles rise, the backward feed, in the direction of the arrow 11, brings the hole C under the fore piercer 4 and the hole B under the needles, ready for the next stage. In this second stage, Fig. 11, the needles descend with their points together into the hole B, already partly sewn with the previously formed corner stitches b<1>, b<2>, and shaped by the auxiliary piercer 10. In descending, the needles move apart to form the stitches b<3>, b<4>, and the forward feed (arrow 12) brings the hole B under the piercer 10 for shaping, the hole C under the needles and the hole D under the piercer 4 for the second time. In the third stage, the needles penetrate the fabric in their most separated position and produce the anchoring stitches on opposite sides of the hole C. The fabric is then fed forward to bring the hole C under the rear piercer for a first shaping, the hole D under the needles, and a portion of fabric under the piercer 4 for a first perforation. This position is the same as in Fig. 10, but one hole further and the cycle of operations repeated. The piercers are carried by the needle bar. Needles vibrating laterally. The needles are vibrated by a cam 20, Fig. 16, through the intermediary of the rod 21, regulating segment lever 22, rod 23, jointed parallelogram 24, rods 25, 26, and needle carriers 27. The cam 20 revolves at a third of the speed of the main shaft 30. Feed. The feed cam 32 drives the feeder 39 backwards and forwards by the intermediary of levers and connecting rods 34, 35, 36, 37 and 38, Fig. 17, and the feed lift cam 33 operates to impart rising and falling movements by the rods 40, 41, 42, 43. The length of feed is regulated by altering the rise and fall movements. This is effected by a moving an arm 47 over a graduated quadrant 48, so turning an eccentric bush 44 carrying the pivot 45 for the lever 40. This alters the position of the end of the lever 40 carrying the follower 46 tracking the cam 33 and so alters the feed stroke.

Title: Improvements in or relating to photographic developing and printing apparatus
IPC: G03B27/06
Filed: 1922-10-28
Abstract: 207,559. Cigarini, A. Oct. 28, 1922. Developing-apparatus for roll films combined with printing- apparatus for printing from a film on to a sensitized paper strip comprises a light-tight casing a, in which the printing takes place, having a shuttered aperture t to which may be attached either a developing, a fixing, or a washing tank u. To the lid of the casing a, is fitted, a box 12 having a clear glass bottom 13, a ruby glass pressure platen 17 carried bv links 19, 20, operated by a handle 22, a pocket 29 for sensitized paper, guide rollers 28, spools m, o, 27, a printing light 26, ruby inspection windows 30, an inspection light 35, and a light-proof film box f provided with a shutter g. The tank a contains water to the level 11-11 and an inspection light 36 is protected therefrom by a glass plate 38. In use a roll of negatives is unrolled until the sensitized film appears, and a weight 39 is clipped to the end. The film and the weight are placed in the box f and the shutter g is closed so that the end of the black paper covering of the film projects between the pads j, h. With the shutter g held closed the black-covering is pulled to unwind the film until the end of the film appears, the black covering is torn off, and the free end of the film is attached to the spool m. A tank u is secured to the casing a, the film is wound on to the spool m, and the shutter g is removed to allow the weight 39 to drop from the box f. The shutter s is then withdrawn and the film can be lowered into the developer tank u, the weight 39 preventing the film from curling-up. The tank u mav be replaced afterwards by other tanks to complete the development. The positions of the spools m, 27 are then changed, the end of the film is connected by tapes 40 to the spool o, and printing paper in the chamber 29 is connected by tapes 41 to the spool m. The spools m, o are simultaneously rotated until a complete picture appears between the plates 13, 17. The handle 22 is lowered to press the film and paper together and at the same time to close the contact 23 to operate the printing light 26. This operation is continued until the whole of the exposed printing paper is on the spool m. The printing paper is then developed in a similar way to the negative film except that the weight 39 is not used, as, owing to its wet condition, the printing paper does not tend to curl up. To allow the use of various widths of film a spool as shown in Fig. 4 is preferably used, in which the flanges 47 can be axially adjusted by rotating the spindle 48 which is screwed right and left handed.

Abstract: 328,673. Boer, H. P. den. Nov. 3, 1928, [Convention date]. Bakers' ovens.-In a travelling oven with steaming-chambers formed by cross plates 8 carried by. a conveyer 7 driven at the same speed as the main conveyer, the cross plates are hinged so that they will be flat on the upper rim of the conveyer 7. Steam tightness of the chambers is ensured by driving the main conveyer from the shaft 4 so that the floor plates 3 are pushed into close contact; by the provision of spring-pressed sealing strips 26 beneath the edges of main conveyer, and of rubbing edges 27 along the sides of the plate &c., and by inclining the two conveyers slightly towards one another in their direction of movement, so that as the plates 8 advance they will press with greater force on the main conveyer. The plates 8 are formed with wide bearing feet 19, and their hinge pins take into slots 14 so that a slight vertical movement of the plate is allowed. The plates of the main conveyer are resiliently supported by springs 21. When in their vertical position the plates 8 abut against stops 17, and they may be held out of action by bars inserted in slots 28<a> and beneath the arms 28. Steam is supplied through ports 11 under control of valves, which may be automatically operated by the conveyer, and is exhausted through the flue 12.

Inventor: LAW HARRY BERNARD
IPC: H04J1/18
Filed: 1958-01-31
Abstract: 860,662. Carrier multiplex systems. POSTMASTER GENERAL. Jan. 23, 1959 [Jan. 31, 1958], No. 3329/58. Class 40 (4). In a multi-channel carrier telephone system the carrier frequency of one channel falls within the frequency band of an adjacent channel. As shown, incoming speech signals in the frequency band 300-2200 c/s are passed by high-pass and low-pass filters 1, 2 to a channel modulator 3 where they modulate a carrier of frequency 10.25 kc/s. (A channel) or 9.75 kc/s. (B channel). In the A channel the lower sideband 8.05- 9.95 kc/s. is selected by a band-pass filter 4, and in the B channel the upper sideband 10.05- 11.95 kc/s. is similarly selected. Band-stop filters 5 suppress the 9.75 kc/s. and 10.25 kc/s. carrier leaks. The A and B channels are then combined to form a two-channel sub-group, 8-12 kc/s. approximately, which is translated to any desired position in the frequency spectrum by further modulation and filtration. Limiters 8 prevent overloading of the system by high-level speech signals.

Abstract: 771,842. Flexible laminates. GOODYEAR TIRE & RUBBER CO. Feb. 7, 1955 [Sept. 24, 1954], No. 3539/55. Class 140. A laminated material suitable for packaging is made by heating and stretching to a thickness not exceeding 0.0005 in. a thermoelastic film 19 as it is brought into contact with one of a pair of rolls 17, and passing the stretched film through the bite of the rolls whilst adhesively uniting it with a sheet material 8 which is non- elastic at the laminating temperature. The stretching of the film is effected by passing it, on its way to rolls 17, over a roll 20 driven at a fraction of the speed of rolls 17. The heating of the film, which may be effected by heating the roll 17 which contacts it, is of sufficient duration to anneal the film until it loses its tendency to shrink. The thermoelastic film, which may be of rubber hydrochloride, polythene, a polymer or copolymer of vinyl chloride, or cellulose acetate, may be united to one or both sides of the other sheet material, e.g. metal foil such as aluminium or lead foil, kraft, glassine, or parchment paper, chip board, fabric, or regenerated cellulose foil. The adhesive, which may be drying or non-drying, a natural or synthetic material, may be applied as a latex, a hot melt, or a lacquer. Microcrystalline wax with or without butyl rubber is used as adhesive for uniting rubber hydrochloride film to aluminium foil, and a butadiene-styrene copolymer latex for uniting rubber hydrochloride film to a porous material. Rubber or cellulose acetate solution may also be used.

Abstract: 1449961 Hydrostatic transmissions POCLAIN 28 Jan 1974 [9 Feb 1973] 03874/74 Heading F2W [Also in Division E1] An earth working machine comprises a frame 4, Fig. 1, front and rear wheels 5, 7 driven respectively by first and second hydraulic motors 21, 22, Fig. 3, working equipment 3 articulated to the frame, a double-acting jack 8 coupled between the frame and working equipment, and an hydraulic control system which automatically adjusts the working equipment in dependence of the torques opposing the front and rear wheels. Included in the control system is a three-position distributer 14 which, in a first position connects one chamber 12 of the jack 8 to a supply 19 of pressurized fluid 17 and the other chamber 13 to a discharge reservoir 20, in a second position reverses the arrangement, and in a third position disconnects the chambers. Automatic selection of the distributer position is achieved by means of a double-acting jack having chambers 37, 38, which can, by means of a second distributer 39, be placed in communication with the fluid lines 31, 33 to the motors 21 and 22. If, for example, the front wheels 5 were to lift off the ground (Fig. 1) pressure in the supply line 31 would drop and distributer 14 in communication therewith would be moved into its second position wherein fluid would be fed to the chamber 13 to extend the jack 8 and lower the front wheels. A spring 36 tends to maintain the distributer 14 in its third position when the pressures in the chambers 37 and 38 are equal. In an alternative embodiment, Fig. 4 (not shown), the position of the distributer 14 is selected automatically by means of a pilot fluid from a low-pressure source (57). A second three-position distributer (49) has its position governed by the highpressure supply to the motors 21, 22, and this distributer (49) supplies the low pressure fluid to one of the chambers 37, 38 of the distributer 14 in one position and supplies the fluid to the other chamber in another position. In each hydrostatic transmission a reversing valve 25, 26 has a position in which the wheels are hydrostatically braked, and these valves 25, 26 may be operated separately or together.
