IPC: G01S1/02
Filed: 1948-03-04
Abstract: 648,713. Automatic control systems for radio direction finders. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 4, 1948, No. 6817. [Class 38 (iv)] [Also in Group XL (c)] In a switched cardioid radio direction finder synchronous input and output switching is effected by two pairs of contacts on an electromagnetic vibrator and two further pairs of contacts producing an alternating potential synchronous with the cardioid switching may be used to provide one input to an electric motor used to automatically align the aerial system with the incoming signal. The vibrator may be of the type used in car radio receivers, the armature 7 being earthed and being actuated by a coil 1 connected to the lowtension source 3 in series with contact 6. Contacts 8 serve to provide a square switching wave-form applied to device 16 to alternate the polarity in which the output of omnidirectional A is applied to receiver 17 to which the loop aerial L is also coupled. One output of receiver 17 is applied for alternate half cycles of the switching frequency to indicator 22 under control of contacts 9, this arrangement is described in Specification 647,804, [Group XL (c)]. Further contacts 23<SP>1</SP>, 24 generate a wave of the cardioid switching frequency across the secondary 30 of a transformer which is fed to one phase winding 33 of a motor 32, the other winding 34 being fed with the output of receiver 17. Motor 32 provides the drive to rotate loop aerial L until the receiver 17 gives zero output when the motor stops.

Title: Improvements in or relating to sewing machines
IPC: D05B59/02
Filed: 1927-03-12
Abstract: 291,889. British United Shoe Machinery Co., Ltd. March 12, 1927. Mechanism for automatically extracting thread spools. - A sewing-machine has mechanism for indicating when the thread remaining on the spool exceeds a given quantity, and for ejecting the spool when that quantity is passed. The invention is described as applied to an outsole sewing-machine having the sewing parts described in Specification 23478/10 and the shaft-operating mechanism described in Specification 24331/12. The thread-spool 142 fits on a sleeve 164 on a stud 162 in the spool case 144. The spool turns as the thread is unwound and turns the sleeve by friction to bring a wing 166 thereon against a stop 167, Fig. 10, in the case 144. In this position, the spool ejector arm 172, which is urged forward each time the machine is stopped, is prevented from entering the case by the wing 166. When the thread is exhausted to a certain point, Figs. 9 and 12, the direction of its winding, and hence the direction of rotation of the spool, is reversed, and the wing 166 is swung away from the stop 167. When the machine is then stopped, the arm 172 can enter the casing 144, Fig. 14, and this allows a latch 220 pivoted on the arm to engage its shoulder 224 on a block 226 on an arm 192, Fig. 7. Until the wing 166 is moved from the stop 167, the arm 172 cannot move far enough to effect this and the latch 220 rides idly under the block 226. The arm 172 is carried by the lever 168 and is moved up to the spool case each time the machine is stopped by the spring-pressed sleeve 176 on the shaft 174, which in turn is reciprocated by a pivoted lever 192, Fig. 4, having one end 196 engaging the sleeve 198 and the other actuated by the lock bolt slide 80 of the mechanism described in Specification 24331/12. When the wing 166 is in stopping position, the arm 172 is arrested, indicating a sufficiency of thread on the spool, the arm 192 moving idly over the latch 220 on the arrested arm. When the thread is almost exhausted, the wing 166 no longer stops the arm 172, which enters the casing 144, allows the latch to engage the arm 192, which then pushes the arm 172 forward to eject the spool. In order that the spool ejecting arm 172 may not interfere with the passage of the loop of needlethread about the spool case, the forward movement of the arm 172 is delayed until the loop is drawn from the case by providing that the block 182 on the rear of the shaft 174, which engages the periphery of a cam disc 216, enters a recess 218 on the disc at the appropriate time. Specification 206.085 also is referred to.

Title: Improvements in the production of sheets from transparent water-resistant organic film-forming substances
IPC: B29D7/01
Filed: 1940-04-18
Abstract: 540,530. Artificial sheets. ROONEY, J. H., HAWTIN, P. R., and SHAW, B. April 18, 1940, No. 7017. [Class 2 (ii)] A sheet is formed from transparent waterresistant organic film-forming substance by depositing a solution of the substance in a volatile solvent on the surface of a solid support to which the substance adheres, removing volatile solvent from the solution and stripping the sheet so formed from the support, the stripping being facilitated by soaking the sheet, while still attached to its support, in a bath containing liquid adapted to change the dimensions of the sheet ; the process may be applied to the production of sheets from esters, ethers, mixed esters, mixed ethers and ester-ethers of cellulose, polyvinyl derivatives, ethers of polyvinyl alcohol, poly-methyl methacrylate, resins of the polystyrene series and co-polymers of two or more polymerized vinyl derivatives or similar polymers of unsaturated substances. A cellulose acetate sheet may be stripped from its glass support by soaking it in water which has a slight swelling action on the cellulose acetate and the evaporation of the volatile solvent of the dope may be carried much further than usual before the stripping treatment thus shortening the time required for seasoning. The sheet may be built up to a thickness of at least 0.05inch by the successive formation of a number of layers one upon another, each layer being deprived of the bulk of its volatile solvent before the formation of the next layer ; the sheet may be loosened from its support by immersing it in an aqueous bath while it contains about 10-15 per cent of water-soluble volatile solvent, stripped from the support and dried, while held flat, in a current of warm air. Specifications 483,242, 533,788, 533,789 and 538,024 are referred to.

Abstract: 914,723. Shovelling equipment. HUTT, L. W. March 5, 1959 [March 5, 1958], No. 7028/58. Class 68 (1). [Also in Group XXX] A tractor-mounted scoop is pivoted about an axis 31 which enables it to act down the side of a trench, turn to cut across the bottom, and turn to cut up the near side of the trench. As shown the scoop 26 is lowered to cut the sides of the trench by lowering the tractor lift arms attached to lugs 14 on the beam. The tractor is moved forward to cut the bottom of the trench, and the boom is raised for the upward cut by raising the lift arms 17, the cable 33 controlling the angle of the scoop. The earth is deposited by pulling a cable 47 which releases a catch 49 and pulls an arm 46, rigidly secured to a lever 45 pivoted about its pivotal axis 41 on the boom thereby engaging a pin 50 with the ground, as shown in Fig. 10, and inverting scoop 26 through cable 38. The lever 45 reverts to the position shown in Fig. 1 on reversing the tractor. Lugs 32 on the side of the scoop rest against members 22 and maintain the scoop on an over centre position as shown in Fig. 10. In a modification, the pivot 27 is replaced by a pawl which hooks on to a bar on the tractor, and on release allows the boom to fall, the boom pivoting about the lugs 14. In a further modification, the lever 40 can be replaced by an hydraulic cylinder for inverting the scoop. Tensioning cable.-To prevent a loose stretch of rope accumulating near the scoop, a block 58, Fig. 4, is urged, by springs 60 to exert a frictional force on the rope 38.

Class 108(3) A flexible support comprises a piece of flexible resilient material A having a hole extending through it engaged by a stud C<SP>3</SP> comprising a rod portion and spaced annular shoulders C', C', secured to the rod portion at each end of the hole, the material A surrounding the hole being circumferentially stretched to grip the stud C', and axially compressed between the shoulders C\ C<SP>2</SP>. The material may be bonded to the stud B. The ring may alternatively be of rectangular shape in crosssection (Fig. 4, not shown), or of a diamond shape (Fig. 5, not shown). The interior of the ring may be filled with felt, sponge rubber, a viscous material, or silicone rubber. The shoulders C<SP>1</SP>, C' may be clamped by means of nuts on the stud B instead of being integral as shown. In a further modification (Fig. 8, not shown), the ring A is elongated so as to be in the form of a tube and a plurality of studs B are spaced along the axial length of the tube on diametrically opposed sides. The ring A, in another form, is of elongated oval cross-section (Fig. 7, not shown) and there are two studs B on either side of the ring. The mountings may be assembled in the ring of Fig. 1 by means of a mounting F (Fig. 13) which has a vertically extending portion of semi-circular channel section. This is engaged with one-half of the bore of the ring A, as shown, while a tapered leader member G having a stud B screwed to its wide end, is engaged with the hole on the other side of the ring A. The member G is then turned into a vertical position by distorting the ring A, and the shoulder C<SP>2</SP> is engaged by a punch F' (Fig. 15) which drives the member G through the hole into the ring A until the stud B is in position, the other side of the ring A coming into abutment with a shoulder F<SP>1</SP> of the support F. The process is then repeated for the other hole in the ring A. In another method (Fig. 17), both studs are inserted in their respective holes in the ring A in a single operation. While the ring A rests on a rubber block H, a tapered leader member J carrying both the studs B is forced through the two holes of the ring A by means of a punch K.
