Title: Improvements in or relating to heating devices
IPC: F02B25/00
Filed: 1944-11-24
Abstract: 592,980. Air heating furnaces. BORG-WARNER CORPORATION. Nov. 24, 1944, No. 23454. Convention date, Nov. 5, 1943. [Class 64 (i)] [Also in Groups XI and XXVIII] A portable, self-contained heating device for heating cabins or for warming engines, comprises a two stroke internal combustion engine A, a heat exchanger B, a fuel tank C, carburettor D, and accumulator E. The engine A has a cylinder 20 having a larger diameter at its lower end than at its upper to accommodate a stepped piston 24, the lower part of the cylinder and the crank-case having inlets 36 and 40 and outlets 44 and 48 respectively. Each of these ports has a one-way valve such that as the piston travels downwards air is drawn in at 36 and forced out under pressure at 48, and in at 40 and out at 44 on the upstroke. The air under pressure is led via a conduit 54 to the accumulator E from which it can enter the combustion chamber of the heat exchanger via conduits 56 or 72, or enter the top of the engine cylinder via a conduit 28. The fuel in tank C is supplied under pressure through a pipe 74 to the carburettor D from which it is forced into venturis 82 and 84 to be carried by the airstream into the respective combustion chamber for igniting. The combustion gases from the heat exchanger are rejected to atmosphere through a pipe upon which is mounted an exhaust regulating device 116 which serves to maintain the pressure in the heat exchanger for any ambient pressure. Air to be heated passes through the channels of the heat exchanger, and in a modification, Fig. 2, the exhaust gases are mixed with it the device 116 being dispensed with, and a conduit leads exhaust gases from the cylinder to pre-heat at 142 the air fuel mixture entering the heat exchanger, whilst air drawn from the atmosphere by the conduit 136 for delivery to the engine is pre-heated due to its proximity to the heat exchanger. It is possible by means of the needle valves 92 and 100 to adjust the air fuel ratios to the engine and heat exchanger separately.

Title: Improvements in or relating to drying apparatus
IPC: F26B15/00
Filed: 1919-10-01
Abstract: 152,505. Imray, O., (Secord, F. A.). Oct. 1, 1919. Chambers; wheeled trucks, moving.-Relates to apparatus for drying bricks and other plastic materials in which the bricks are stacked on hollow supports adapted to be moved into position contiguous to a hot-air supply duct, means being provided for connecting the supports with the duct. According to the invention, the uppermost supports are pivotally mounted so that they may be moved to give access to the lower supports. The hot-air duct 1, Fig. 1, is preferably arranged beneath the floor and is provided at intervals with openings 3, which may be closed by covers 4. The hollow perforated supports 11 for the articles to be dried are mounted on a conveyer 5 which may be suspended from an overhead track 6 arranged parallel to the duct, so that conveyers can be run into position over the duct. The supports 11 are arranged in two or more superposed layers, the uppermost supports 18 being pivoted at their ends in order that they may be moved to give access to the lower supports. The conveyer may be open or may be provided with removable sides and covers. A header 14 secured to the end of the conveyer is connected with the supports 11, and is also provided with a coupling-pipe 35<1>, which is lowered into an opening 3 in the air duct. Thus the hot air from the duct passes through the header 14 into the hollow supports 11 and escapes through the perforations, finally passing out of the conveyer through openings 67. The articles are dried by the hot air and by heat radiated from the supports, and the drying is assisted by a layer of absorbent material 17 placed in the supports. The apparatus may be modified by mounting the conveyers on trucks running on a track on the floor and by arranging the duct above the tracks and the conveyer. The duct may also be placed at the end of the track, a tapered coupling fitting into an opening in the duct and similar connexions being made between a number of conveyers.

Title: Method and apparatus for producing stitching patterns cyclically
IPC: D05B21/00
Filed: 1972-05-23
Abstract: 1371668 Sewing machines VIRGINIO RIMOLDI & C SpA 23 May 1972 [17 June 1971] 24201/72 Heading DIG In a sewing assembly a workpiece is held against a table top 2 and moved along by a clamping arrangement 12, through a sewing machine 4, the speed of the clamp being changed at chosen points during the cycle by control circuitry. There are a series of holes in the table top, and air is sucked down through them to keep the workpiece flat on the table. The clamp approaches the machine at a first speed, slows down to allow stitching of a short length of seam at a second speed, completes the main part of the seam at the first speed, slows to finish the seam at the second speed, travels to the workpiece discharging station at the first speed and stops. The clamp is raised thus activating a switch 72 to reverse the direction of movement and the clamp returns to the beginning at a 3rd speed, higher than the 1st speed. To permit accurate positioning of the clamp on the workpiece the speed is reduced to a 4th speed, slower than the 2nd speed. The speeds are altered at the chosen positions by a timing device, and the three lowest speeds may be varied. The clamp is driven by a continuously running motor 5 and a chain 6, prongs 9 on the clamp carriage engaging the upper or lower run for forward or return movement respectively. A guide groove 17 on the clamp engages a peg 18 on the sewing machine to displace the clamp transversely to sew a curved seam, the clamp being unlocked for transverse movement only after its leading edge actuates a sensor 62. Telescopically extending arms 13, 14 join the clamp to a carriage 3 and a pneumatically operated piston 30 raises and lowers the arm. Initially the clamp is positioned using a template 19. A pneumatically actuated thread cutter device 68 is provided to cut the thread after the sewing machine has stopped. To begin the cycle a foot pedal 32 is operated to lower the clamp onto the workpiece, and the starting button 48 is pressed. By pressing and releasing the foot pedal the clamp may be lifted and lowered. Sensors 60, 61, 62, 65, 72 and photo electric cell 46 operate in conjunction with electric control circuitry (Figs. 8, 9, not shown) which actuates pneumatic controls (Fig. 10, not shown).

Title: Improvements in electrical control relays
IPC: H01H53/10
Filed: 1936-09-04
Abstract: 484,397. Induction relays. PINTSCH AKT.-GES., J. Sept. 4, 1936, No. 24248. Convention date, Sept. 26, 1935. [Class 38 (v)] In a relay of the Ferraris disc type, two oppositely-directed driving moments normally balance each other ; when the value of some physical quantity such as current or voltage varies from a prescribed value, the balance of these moments is disturbed, one increasing and the other decreasing with the result that movement occurs and the relay is operated. As shown in Fig. 1, an induction disc 1 in which normally equal and opposite torques are produced by fixed shaded-pole magnets 4, 5 is mounted at the upper end of a pivoted arm 6. On a predetermined variation of a supervised value (for example, current or voltage) the arm 6 is rocked against a spring by the attraction of an armature carried at its lower end to an electromagnet 8 so that the balance of torques in the disc is at once disturbed and the disc at once rotates to bring one or other of two pairs of contacts 9 into engagement. In a modified form, Fig. 2, two discs connected by gearing 14-17 are employed, both discs extending in an air gap of an electromagnet 11. The electromagnet is carried by an arm pivoted at 18 and normally the attraction of a fixed unsymmetrically-disposed piece 19 balances the pull of a spring 20 acting on the arm so that the shaded-pole electromagnet is symmetrically disposed with relation to the two discs and produces equal and opposite torques therein. With increase or decrease of current above or below the predetermined value however the driving electromagnet is raised or lowered by the varied attraction to the member 19, so that the balance of the torques of the two discs is disturbed. The discs thus immediately commence rotation in the corresponding direction.
