Filed: 1938-09-05
Abstract: 510,391. Meat preparations drying meat extracts. FISCHER, N. C. Sept. 5, 1938, No. 25886. [Class 49] A meat concentrate is prepared by heating an aqueous meat extract to coagulate heatcoagulable constituents therein, separating the coagulated matter and spray drying the extract to give a powder containing not more than about 2-5 per cent. by weight of moisture. The powder may be moulded to cubes, blocks &c. and seasonings such as salt and spices may be added to it. In the example given, the meat juices from a packing house, e.g., the cooking water, and the soup water from canning rooms, are collected in a vessel 1 and passed to a vessel 2 in which they are heated to about 170‹F. to coagulate the heat-coagulable albumens and other proteins which are separated in a filter press 3, the extract being next concentrated in an evaporator 4 to a solids content of 10-25 per cent. by weight. The extract is then passed, preferably at about 130‹F., to the nozzle 6 of a spray drier 5 to which air heated by coils 9, e.g., to about 325-330‹F., is supplied through an inlet 7, the air leaving through an outlet 10 having a dust collector 11. The dry product is removed through outlet 8 and may be packaged as such or compressed. Salt and similar seasonings may be added to the extract prior to introduction into the sprayer.

Abstract: 723,492. Controlling vehicles. MASSEY-HARRIS-FERGUSON (SALES), Ltd., [formerly FERGUSON, Ltd.,H.]. Oct. 16, 1953 [Oct. 17, 1952], No. 26056/52. Class 79(5). [Also in Group XXXIV] In a tractor brake latch mechanism applicable to a brake pedal and comprising co-operating pawl and toothed rack components, of which the rack is rigidly secured to the pedal and the pawl is pivotally mounted in a stationary location, a manually operable control lever, movable by the driver into a latching setting and an unlatching setting, is connected with the pawl to force the pawl into engagement with the rack and out of engagement with the rack, alternatively according to the setting of the control lever. Figs. 1 and 2 illustrate the rearwardly extending brake pedal 6 in its inoperative or " off " position. A casing 11 is adapted to be secured to the tractor and houses a hand control lever 15 which is operatively associated with a spring biassing device 16 to 21 which is applied to a pawl 9 pivoted to a bracket 22, secured to a stop 8 fixed to the tractor, and which functions with a tumblerswitch action. The pawl 9 co-operates with a ratchet-toothed rack plate 10 rigidly secured to the brake pedal 6. In operation, when the tractor driver wishes to perform the braking and latching operation, he depresses the pedal 6 against the action of a spring (not shown), which holds the pedal against the stop 8, so as to apply the brakes adequately. Then, simultaneously he moves the hand control lever 15 to the opposite end of the slot 14 and the pawl 9 is pivoted to engage with the teeth of the rack plate 10. The brake pedal 6 is then securely latched against upward movement and can only be unlatched by forward return movement of the hand control lever 15. A modification is described and illustrated in which the invention is adapted for use on tractors with a forwardly extending brake pedal 6 ; this includes a modification to the spring biassing device 16 to 21.

Title: Stacking sheets, particularly those delivered from rolling mills
IPC: B21B39/00
Filed: 1929-08-29
Abstract: 319,271. Bonnot Co., (Assignees of Lentz, G. W.). Sept. 19, 1928, [Convention date]. Delivery apparatus. - A device for stacking sheet material is described with reference to stacking polished sheets on delivery from a coldrolling mill. The feed table, roll pass, and deliverv table are all arranged in the same plane to avoid buck. ling of the sheets. The delivery table comprises a series of parallel shafts 16 some of which are geared together by a chain driven by a sprocket through gearing from a motor 21. The shafts carry staggered discs 22 that form a roller table for the sheets. On reaching the end of the table the edge of the sheet enters between fingers 59, 60 which check the motion of the sheet bv a bevelled surface, the upper finger 59 being pivoted to yield when the sheet is turned over by the stacker. The fingers are carried by a lever 57 and the impact of the sheet rocks the lever and slides a bar 55 which rocks levers 62, 51. The lever 62 withdraws a pin 64 from a notch in a drum 66 and registers it with an annular groove 65. The lever 51 acts through a yoke and toggle links 50 to engage a clutch 46 and transmit drive from the motor to a shaft 23 on which are secured a series of pairs of plates 25 located between the shafts 16. Arms 26 having slots 30 are mounted on the shafts 23 between the plates by means of rollers 29 carried by the plates. Notches 34 located at opposite sides and ends of the arms are engaged alternately by detents 31 on the plates. When the clutch is engaged the arms 26 swing upwards between the shafts 16 raising the sheet and turning it over on to a stack 38. After half a revolution an inclined part 65<c> of the annular groove cams the pin 64 into a second notch in the drum 66, thereby locking the shaft 23, disengaging the clutch 46, and resetting the lever 57. Shortly before this action fixed pins 36, Fig. 7, engage arms 35 secured to the detents 31 and cam them out of the notches 34. The arms then slide radially over the rollers 29, being guided by a surface 67 until the other set of detents engage the notches at the other ends of the arms. The device is then ready for the transfer of another sheet which by this construction may be delivered from the mill during the transfer of the preceding sheet.

Filed: 1971-04-19
Abstract: 1347344 Transistor logic circuits SIEMENS AG 19 April 1971 [2 April 1970] 26528/71 Heading H3T A logic gate 2, 3, 4 has constant current transistors T24-T26, T35 and T46 in respectively the input stage 2, switching stage 3 and output stage 4, to permit replacement of circuit resistors by transistors thereby facilitating integrated construction. The gate, and further gates (not shown) share a common current supply circuit 1 which has transistors T11 to T16 defining a constant current in a divider R12- R14, which provides voltages U H1 , U H2 , U H3  to various parts of each gate. Only if all inputs E1<SP>1</SP>, E2<SP>1</SP>, E3<SP>1</SP> are high is the point K held high by R21; when an input falls to zero, the corresponding diode D21, D22 or D23 conducts and transistors T17, T18 supply the current to the corresponding constant current transistor T24, T25 or T26. A high output turns on T31 in a threshold circuit 3, the output being taken from a pair of transistors T33, T34 in the collector circuit of either T32 as shown, or T31, according to the desired polarity of the output. The output L of the threshold circuit drives an output driver circuit 4, where pairs of transistors T47, T48 and T49, T50 alternately control the output A. Negative feedback T41, T42, T43 is provided, and constant current sources T44- T46 are included. Protection features include: D24 with Zeners Z11-Z15 short out positive surges from the inputs appearing at T21-T23 collectors; D25-D27 dispose of corresponding negative surges; D14 shunts positive peaks in the supply U; diodes D42, D43 protect the output stage. Emitter resistors R11, R15 &c. enable the constant currents to be preset. An RC delay stage (Fig. 2, not shown) between point K and the threshold circuit 3 uses transistors as the "R", and gives immunity from spurious spikes.

Title: Improvements in or relating to the production of artificial filaments, films and other structures by extrusion of molten or plastic compositions
IPC: B29C48/05
Filed: 1939-09-29
Abstract: 535,186. Artificial filaments, films &c. DU PONT DE NEMOURS & CO., E. I. Sept. 29, 1939, No. 26883. Convention date, Sept. 29, 1938. [Class 2 (ii)] [Also in Group XXVI] Artificial filaments, yarns, ribbons, sheets, and other structures are made by subjecting a molten composition, e.g. a polyamide composition, which is liable to develop bubbles under the conditions of extrusion, to a pressure sufficient to eliminate any bubbles, forwarding the bubble-free composition at a constant rate to an extrusion device and extruding the bubble-free composition, preferably while maintaining it under sufficient pressure to prevent re-formation of any bubbles. The process is of particular utility in the spinning of molten organic compositions subject to bubble-formation as a result of decomposition when in molten state. The process is also applicable to the spinning of solutions of filament-forming compounds. As shown, solid organic filament-forming composition is placed in a container 5 and melted by the grid 7. The molten composition drops through the grid and forms a pool 11 which contains small bubbles 13 as a result of decomposition. The composition is pressed by gear-pump 15 to a pressure sufficient to eliminate the bubbles and prevent further bubble-formation, and is passed to a reservoir 17. It is then metered by a gear-pump 19 to a filter-pack 21 made of fine screens which in addition to their function as a filter also maintain the composition under pressure until it reaches the spinneret and is extruded in the form of filaments. The pump 15 has a greater capacity than pump 19. A byepass 25 containing a relief-valve 27 is provided. If the pump has sufficient slip or back-pressure leakage the byepass may be omitted. The pressure applied to the composition is preferably at least 50 lb. per square inch. In an example, polyhexamethylene adipamide is melted under 10 lb. nitrogen pressure at 280C. and fed to the gear-pump 15 which imparts to the molten mass a pressure of 5001b. per square inch and this removes any bubbles. The molten mass is then pumped through the filter-pack and the extrusion orifices to. form filaments. The filament-forming substance may be a polyamide, polyester, polyether, polyacetal, ethylene polymer, vinyl polymer, polystyrene, or polyacrylic acid derivative. The composition may contain resins, plasticizers, pigments, dyes, delustrants, or anti-oxidants. The pressure may be applied by gear-, screw-, or piston-pumps, or by gas pressure using nitrogen, hydrogen, or other oxygen-free gas.
