Title: Improvements in or relating to extrusion machines for example for extruding raw doughnuts
IPC: B30B15/30
Filed: 1941-02-17
Abstract: 547,331. Moulding doughnuts by extrusion. LOWE CORPORATION, J. Feb. 17. 1941, No. 2139. Convention date, Dec. 6, 1940. [Class 87 (ii)] With the parts in the position shown in Fig. 12, air is exhausted from the dough chamber 2 through a pipe 43 and dough is sucked into the chamber from a hopper 3. The plate 4 then moves to the left, isolating the chamber from the hopper, and compressed air is admitted to the chamber through the pipe 43. While compressed air is being admitted, a sleeve valve 15 surrounding the extrusion nozzle 16 is raised from the position shown and dough is extruded by the compressed air over a disc 14 fixed in the nozzle. The sleeve 15 then descends and cuts off the ring doughnut thus formed. The doughnut falls into a compartment of a conveyer 130 running in a frying kettle 119 disposed below the hopper-nozzle unit. The plate 4 retracts to the position shown, more dough is sucked in, and the cycle is repeated. The machine comprises two distinct units, a feed unit A and a control unit B. The dough chamber 2 comprises two compartments, each of which feeds two extrusion nozzles. The nozzle sleeves 15 are raised and lowered by rocking arms 10 having pins 17 which engage grooves 41 on the sleeves. The arms 10 are loosely pivoted on a common oscillating shaft 136, and are locked thereto by clutch devices. Any one of the four nozzles can be put out of action independently of the others by withdrawing a clutch pin 94 to disconnect its lever 10 from the shaft 136 (as shown in Fig. 9). There are two plates 4, one to each dough compartment, and they are reciprocated from a box cam 111 by way of connections including bell crank lever 113 and connecting rod 114. Similarly, the shaft 136 is oscillated by a box cam 121 by way of connections including bell crank lever 127, connecting rod 129 and lever 135. The box cams 111, 121 are driven by an electric motor 50 which drives also a vacuum-compression pump 44 the pressure line 52 and vacuum line 53 of which are connected to a valve 77 which effects alternate suction and pressure in a line 43-67 communicating with the dough chamber. The valve 77 is alternated by a rack-and-pinion drive from a roller cam mounted on the cam 111. Specification 543,372 is referred to. The Specification as open to inspection under Sect. 91 contains the subject-matter of Specification 543,372. This subject-matter does not appear in the Specification as accepted.

Abstract: 1407525 Machine tool control REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 16 Jan 1973 [20 Jan 1972] 2225/73 Headings B3B and B3C In a numerically controlled machine tool for machining, e.g. by a vertical spindle machining unit 1, at successive stations along an elongate workpiece 3, the machining unit 1 is positioned transversely of the workpiece along a gantry 7 by a control device which positions the machining unit 1 by reference to lateral reference faces 4 or 5 on opposite sides of the workpiece and which is able to change the controlling reference face from one lateral face to the other depending on the machining operation desired, and includes means for adjusting the position of the machining unit 1 relative to a reference member, e.g. a lead screw 8, in accordance with numerical control position signals, and means for shifting the reference member between a first reference position, e.g. relative to lateral face 4, and a second reference position, e.g. relative to lateral face 5. The machining unit 1 is moved by a motor 11 driven lead screw 8 and nut 13 drive with the lead screw 8, nut 13 and machining unit 1 being able to float laterally by means of a splined bearing 10 and a plain bearing 9 on the lead screw 8. A pick-up or encoder 12 monitors the rotation of the lead screw. At a given location along the workpiece one of a pair of feelers 15, 15<SP>1</SP> which are axially fixed relative to the lead screw 8 is chosen to engage one of the reference planes 4 or 5 to align a datum 16 or 17 on the lead screw therewith. At the required reference position a jaw 18 attached to the lead screw, is actuated to clamp itself to a fixed blade 19 to lock the lead screw laterally in the datum position. A control programme then controls the rotation of the lead screw to move the machining unit along the lead screw to a predetermined machining position. The feelers 15, 151 are attached to the lead screw by means of pressure operated centering devices 14, 14<SP>1</SP> (Figs. 2-4, not shown) which, when a selected one is pressurized a pair of floating pistons are forced apart to move the lead screw axially to the datum position. If a group of holes for example, are to be machined at a location along the beam a single clamping of the jaw 18 is made to avoid local irregularities on the reference faces 4 or 5 introducing errors. The workpiece may be a regular section I or H beam, an open channel or box beam, or may be a non-linear, non-constant cross-section beam, e.g. a car chassis box member. The machine tool may include machining units for operating on the lateral faces 4 and 5 (Figs. 8-10, not shown).

Title: Process for the carbonization of woollen cloths, and plant for carrying out said process
IPC: F26B13/10
Filed: 1950-02-03
Abstract: <PICT:0690172/IV (c)/1> Woollen cloths are impregnated with a solution of a carbonizing agent, any surplus being mechanically expressed, and the carbonizing agent is uniformly deposited in the body of the cloth in a single drying stage in which a plurality of jets of a gaseous heat vehicle are projected violently against the cloth at such a temperature and in such quantity that the solution is instantly raised to its boiling-point both on the surface and in the body of the cloth to ensure instantaneous volatilization of the solvent in all parts of the cloth.  The latter is then submitted to the continued action of the gaseous heat vehicle to effect the carbonizing reaction.  The gaseous heat vehicle may be a superheated vapour, and is preferably superheated steam.  The gaseous heat vehicle may be violently projected through a plurality of closely-arranged nozzles and, if desired, the heat transfer at this drying stage may be such as to start the carbonization.  Further the carbonization stage may include an inoperative period during which the cloth may be cooled to prevent overheating due to the carbonizing.  As shown, the cloth 1, previously impregnated with, for example, 5 per cent aqueous sulphuric acid and wrung, passes through a slit 3 into the drying chamber 2 between two groups of blowing nozzle-members 4, 5 connected to chests 6, 7.  Drying vapour is fed into the chests from blowers 8, 9, the suction pipes 10, 11 of which open into chamber 2 to make a closed circuit.  Heaters 12, 13 are situated in the chests 6, 7 to heat the vapour to about 120 DEG  C. The dried cloth passes through a slit 14 into the carbonizing chamber 16, which is formed in two compartments, namely, 16a, in which the cloth is heated, and 16b, which contains an accumulating device to allow sufficient time to complete the reaction.  In chamber 16a, the cloth travels between two groups of nozzles 17, 18 supplied with a super-heated vapour also at about 120 DEG  C., the nozzles being connected to blowers 19, 20.  Heating elements 23, 24 are provided inside the chests 21, 22.  After passage through chamber 16a, the cloth passes over rollers into chamber 16b in which it is deposited in folds on the accumulating device 27.  Holes 34 may be formed in this device through which air is drawn through the cloth and into the blower 20.  The carbonized matter may be removed from the cloth by the usual methods.
