Title: Improvements in or relating to sheet stacking devices
IPC: B65H31/32
Filed: 1957-08-15
Abstract: 819,056. Sheet-delivery apparatus. FABER & SCHLETCHER A. G. Aug. 15, 1957 [Aug. 18, 1956], No. 25751/57. Class 100(1) A stacking device for sheets in which, while the machine remains in operation, during the exchange of a main stacking table an auxiliary stacking table 11 is temporarily moved in position over the main stack 12, is characterized by a retaining cylinder 13 in the path of the sheet being delivered adapted to co-operate with sheet conveyers 5 for temporarily withholding one or more of the sheets so that no sheets will be deposited during the introduction of the auxiliary stacking device. The sheets are delivered by grippers 6-9 on chains 5 running over chain wheels 3, 4 mounted between side frame members 1, 2 of the device. The cylinder 13 is provided with grippers 16 which take sheets 14, 15 from the grippers 6-9 when the auxiliary table is being placed in position in guide 10. When the table 11 is in position the retained sheets are released by the cylinder 13 for stacking. The cylinder may be rendered operative either manually or automatically. For automatic operation the table 11 operates a switch 34 when moved to a horizontal position so that gripper operating mechanism 19 causes the chain grippers to open adjacent the cylinder 13 and operating mechanism 20 causes the gripper 16 to close on the sheets released by the chain grippers. When the table 11 is in operative position it contacts a switch 39 which de-energizes the mechanisms 19 and 20. At the same time further gripper operating mechanisms for releasing the sheets on the cylinder 13 and allowing them to be taken by the chain grippers are energized via a switch 36. Means, not shown, is provided to ensure that these further gripper operating mechanisms become operative upon actuation of switch 36 only during one machine cycle and even then only if the mechanisms 19, 20 are previouslyenergized. The grippers comprise movable jaws 22 on a shaft 21 which co-operate with a fixed bar 23. A lever 24 having a cam follower 25 is provided on the end of the shaft 21 for operating the grippers when a cam 26 is in the path of the follower 25. Each operating mechanism, as 19, is arranged to place the cam 26 into and out of the path of the follower 25. The cam 26 is mounted on two studs 27 slidable in the side wall 1 of the device. A crosspiece 28 is mounted on the other end of the stud 27 to which is attached a bell crank lever 30 the other arm of which is connected to the armature 31 of an electromagnet 32. Normally the cam 26 is held in the position shown in Fig. 5 by a spring 33, but on energization of the electromagnet 32 the cam 26 is placed in position to engage the follower 25 of a gripper.

Title: Improvements in or relating to double-action distillation
IPC: B01D3/32
Filed: 1946-08-28
Abstract: In obtaining alcohol of 94 DEG  Gay-Lussac, alcoholic must is divided into two portions, one being distilled at atmospheric pressure and the other under reduced pressure, the resulting vaporous phlegm from the atmospheric pressure distillation and the liquid phlegm from the vacuum distillation being concentrated and rectified together in a rectification column operating at atmospheric pressure.  One portion of the must is supplied through lines 1, 2 to distillation column B, which operates under atmospheric pressure, being preheated in vessel E by the vinasses leaving the base of the column.  The resulting vaporous phlegms pass into rectifying column C.  The other portion of the must is supplied through line 5 to column A, which operates under reduced pressure, the must being preheated in vessel D by the alcoholic vapours issuing from column A via line 6.  The vapours are completely condensed in condenser F, the condensates flowing through lines 8 and 9 to tank P, and residual vapours passing through scrubber K.  The condensate from tank P is pumped via preheater G, where it is preheated by the vinasses from column A, into <PICT:0626658/III/1> the rectification column C.  The rectified vapours from column C pass through condenser-heater J and condenser H to yield head fractions.  Distillation column B is heated by steam coil S, condensed steam being passed through line 20 to the alcohol condenser-heater J where it is vaporized under the reduced pressure produced by the pump L and passes through line 21 to bubble in and heat column A.

Title: Remote cutoff field effect transistor
IPC: H01L29/76
Filed: 1965-06-21
Abstract: 1,098,345. Field-effect transistors. MOTOROLA Inc. June 21, 1965 [July 24, 1964], No. 26130/65. Heading H1K. The transverse cross-section of the channel of field effect transistor comprises at least two regions of different thicknesses. As shown, Fig. 3, the channel comprises a plurality of alternate thick and thin regions. The thin regions provide a high initial transconductance while the thick regions provide a high cut-off voltage. The device is produced by depositing a silicon dioxide layer (61) on a P-type silicon substrate (60), Fig. 10B (not shown), etching rectangular openings (62) in oxide layer (61), Fig. 10C (not shown), and diffusing boron into the exposed surface of the substrate, Fig. 10D (not shown). The oxide layer is removed and a layer (64) of N-type silicon is epitaxially deposited during which process the boron diffuses out of substrate (60) to form P-type regions (31<SP>11</SP>), Fig. 10E (not shown). A P-type silicon layer (67) is epitaxially deposited over the N- type layer (64), Fig. 10F (not shown), and boron is diffused through an oxide mask to produce P-type region (71) extending between the two P-type layers to surround and isolate channel region (33), Figs. 10H and 10I (not shown). Phosphorus is diffused through an oxide mask to form source and drain regions (78, 79), Fig. 10K (not shown), and aluminium is vacuum evaporated to form source and drain contacts (16, 17), Fig. 10L (not shown). A layer of gold is vacuum evaporated on to the lower face of the substrate. A plurality of transistors are formed simultaneously in a large wafer which is divided into individual dice each of which is mounted on a gold-plated header, Fig. 1 (not shown), by heating to above the gold-silicon eutectic temperature so that the gold alloys with the silicon. Aluminium films are deposited on the ends of lead-out wires (20, 21) which are joined to source and drain contacts (16, 17) by fine aluminium wires (18, 19) attached by pressure welding. Lead-out wire (23) is bent over and contacts header (14) which forms the gate contact. The encapsulation is completed by welding a cap (25) to the header. The aspect ratio of the thin regions of the channel is made large to increase the initial transconductance of the device. The transverse cross-section of the channel may alternatively comprise a single thin region flanked by two thick regions, Fig. 8 (not shown), and this may be modified by reducing the thickness of part of the thin region to produce a channel comprising regions of three different thicknesses, Fig. 9 (not shown).

Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/52
Filed: 1939-09-19
Abstract: 534,857. Cigarette-making machines. EDWARDS, W. F. M. Sept. 19, 1939, No. 26147. [Class 130] In the production of filter tip cigarettes, a continuous length of tobacco is fed on to a rotating circular or polygonal member 12 and is severed into portions which are separated from one another by arcuate relative motion, to form spaces for the reception of filter tips. The circular member may be arranged vertically, horizontally or at an angle. In the case of a polygonal member, the relative motion may include a radial component in addition to an arcuate component. The filter-tip material used may be filter tips, wads or plugs of any suitable material, or tubes empty or filled wholly or partly with filtering material or tobacco. As shown, a tobacco rod 1 on a conveyer belt 3 is passed under compression wheels 4, 5 and a compression band 6 and is guided by a ramp 8 to a channel 21 in the periphery of the member 12, which is made up of carrier members 9 joined in pairs and running by means of rollers 10 on circular tracks 11, 13 cut in plates 12, 14 bolted together. The carrier members 9 are driven by a gear wheel 18 meshing with teeth 20 on the carrier members. The tobacco is gripped between plates 41 having rollers 42 held by a tension spring 44 in engagement with arcuate cam tracks 43. A reciprocating cutter 22 severs the tobacco between adjacent members 9, and the members 9 are then accelerated so that at the bottom of the member 12 the severed lengths of tobacco are spaced apart sufficiently to fall between filter wads 34 on a paper web 31 when released by the grippers 41. The loaded web then passes through a garniture 39 and the rod thus formed is divided into cigarettes by a knife 40. The acceleration of the members 9 is effected by means comprising a link 24 pivoted at 25 to a cam 23 on each member 9, the free end of the link 24 carrying rollers 26, 26a, the latter running in a cam groove 27 in the plate 14. The groove 27 is mainly circular, but from the point 28 it moves outwards, so that the carrier member 9a is accelerated away from the succeeding member 9b. From the point 29 to the point 30 of the cam track, the carrier member is correspondingly decelerated to close the gap after the release and deposit of the tobacco length.

Filed: 1960-07-28
Abstract: 896,130. Linkwork. CUTLER-HAMMER Inc. July 28, 1960 [Aug. 3, 1959], No. 26268/60. Class 80 (3). [Also in Group XXXVII] In a push-push switch, two consecutive operations of a manually-operable push-button cause the bearing trunnions of a wedge-shaped lever to seat consecutively in each of four separate bearing surfaces. In the OFF condition the switch assumes the position shown, with the trunnions 32e seating in the upper left-hand corner of bearing-recesses 33 in the switch casing. Depression of the push-button 18 depresses also a cup-shaped member 34, the wedge contact 32, contact lever 30 and fulcrum 26c. The trunnions 32e move into the left-hand arcuate bearing-surface 33 and the wedge 32 then rotates clockwise, its point 32a further depressing the fulcrum 26c and then moving to the left of the fulcrum to tilt the bifurcated contact lever 30 and press contacts 30d against the bases of two terminals 40 to complete the circuit. As the push-button 18 is released, the spring-loaded fulcrum 26c rises, causing further clockwise rotation of the wedge 32 to move the trunnions 32e into the upper right-hand corner of the bearing recess 33 and maintain contact pressure with a wiping action. The next depression of the push-button 18 rotates the wedge 32 counter-clockwise, tilting the contact-lever 30 to the OFF position and moving the trunnions 32e into the right-hand arcuate bearing. Release of the push-button 18 restores the switch to the position shown.

Title: Evaporation meter
IPC: G01K17/02
Filed: 1936-09-28
Abstract: 462,812. Measuring heat quantities. CLORIUS, O. T. Sept. 28, 1936, Nos. 26282 and 26283. Convention dates, Oct. 8, 1935 and Oct. 28, 1935. [Class 97 (iii)] Relates to meters for measuring the quantity of heat carried by the fluid in a conduit by the amount of evaporation of a liquid from a vessel mounted on the conduit. A member serving to set the meter in or out of operation, e.g. a valve closing the mouth of the vessel, is mechanically coupled to a closing device for the conduit. A plunger resiliently carrying a conical valve for the mouth of the evaporation vessel, which may be mounted in a frame made in one piece with a tap, may be moved from the closure position when the tap is opened and vice versa by a disc adjustably secured on the handle spindle of the tap and engaging a recess in the plunger. Fig. 3 shows a construction in which the valve 15 for the evaporation vessel 8 is moved from the closure position before the conduit 4 is opened. The valve head 35 of the tap 1 is fixed on the spindle 33 having a hand wheel 3 and has a soft packing 36 and a cylindrical plug 37 which closely fits or has threaded engagement in the hole 38 of the valve seat. The plunger 14 carrying the valve 15 by means of a spring has a button 34 engaging a slot 40 in the hand wheel 3, so that when the latter is turned the valve 15 is lifted from the mouth of the vessel 8 before the plug 37 is completely withdrawn from the hole 38. In Fig. 4, a cock cone 22 has a hollow spindle 23 in which the evaporation vessel 25 is mounted on a cork or rubber plug 31. The stopper 26 for the vessel 25 is carried by a flanged plate 27 screwed into the hub of the hand wheel 24. The latter is threaded on the spindle 23 and is free to move up and down between the shoulder 29 and a nut 30 before it turns the spindle 23 and cock 22.

Title: Radar trilacteralization position locators
IPC: G01S13/87
Filed: 1972-06-06
Abstract: 1390836 Radio navigation DEL NORTE TECHNOLOGY Inc 6 June 1972 [4 Nov 1971] 26332/72 Heading H4D A pulse radar position locator system comprises a first unit for transmitting an interrogation signal to at least two other units, each responding to a particular pulse recurrence frequency (p.r.f.), the addressed unit transmitting a reply signal back to the first unit which determines the distance between itself and the addressed unit by measuring the time between transmission and reception of signals. First unit 50 (Fig. 2), while in the overlapping beam area 67, 68 of other units 62 can determine its distance from each unit and hence its position. When unit 50 is at 69 however, unit 62 cannot give an accurate signal and contact with a further unit is then necessary. In the embodiment of Fig. 3, the other units each reply only to signals of a specific p.r.f. set up by switches 74 and gates 75 controlling generator 76. This feeds the transmitter 55 at the p.r.f. corresponding to the selected stationary unit. A device 81 is set to the number of valid replies required from unit 60 which will give an accurate distance measurement. A circuit 84 routes the transmitter breakthrough from receiver 56 to relay 94 which delays the enabling of gate 97 and hence the start of clock/counter 99 by the processing time in unit 60. The reply from unit 60 is gated through AND gate 100 and p.r.f. detector 98, which detects if the reply pulses are of the correct p.r.f. If so, gate 97 is disabled and device 99 stopped. The count indicates time t 1  + t 2 , the processing time in unit 60 being removed by delay 94. Gate 97, when stopped, supplies a signal to device 81 which stores all subsequent stop signals until the required number have been obtained. The counts in device 99 due to several measurements are stored and averaged in accumulator 106. Every time a transmission takes place from unit 50, a counter 121 is stepped so that a maximum of fifty transmissions are made to stationary unit 60. When fifty such transmissions have been made gate 122 is enabled and measurements stopped. If however, the required number of valid replies are received before the count of fifty, device 81 enables gate 122. Further circuitry is operative to transfer the data in accumulator 106 to registers 128, 129, by virtue of gates 124, 125 depending upon which channel, or stationary unit has been selected. Note that if there have not been the required number of valid replies device 81 does not give an enable output to gates 124, 125 and the data is not transferred. Delay lines 110, 132 facilitate resetting of the apparatus.
