Filed: 1946-04-23
Abstract: 606,091. Numbering hand-stamps. STANLEIGH, E. W. H. April 23, 1946, No. 12258. [Class 10C(ii)] The numbering wheels 8 of a hand stamp can either be advanced automatically or advanced by a hand lever 30. When set for automatic advancement as shown in Fig. 4 a semi-circular locking member 49 mounted on the main frame 5 is turned to engage a recessed arm 50 secured to a lever 48 pivoted to the frame 5 and connected by a link 47 to a pin 35 on the pawl arm 34. For hand advancement the locking member is turned to release the parts 47 and 48, as shown in Fig. 3. The operation of the hand lever 30 swings a frame 38 pivoted to the carrier 7 of the numbering head, in a clockwise direction, thereby pulling a slotted link 36 engaging the pin 35, and thus advancing the numbering wheels 8. A projection 44 slightly lowers the carrier 7 and causes, by mechanism described in Specification 606,090, the inking pad to be moved away from the numbering wheels during the advancing action. During automatic advancing, the hand lever 30 is inoperative and downward movement of the carrier 7 causes the pin 35 to rotate clockwise about the spindle 9 of the numbering head. On the return movement the arm 34 rotates anti-clockwise and the pawls 32 advance the numbering mechanism.

Filed: 1955-04-28
Abstract: 793,459. Fuel injection systems. NSU WERKE AKT.-GES. April 28, 1955, No. 12268/55. Class 7(3) The circulation of fuel in a primary circuit 1, 11, by a low-pressure pump 6 is abruptly terminated by rapid closure of a cyclically operated valve 31, setting up a pressure wave which travels down a pipe 2 to the injector 5 and causes injection. The valve 31 may be operated by a cam or hydraulically or electrically and the discharge of pump 6 is by-passed back to the tank 7 through an adjustable valve 101 during the periods when the valve 31 is closed. The amount of fuel injected on each cycle is varied by an adjustable throttle 9 in the primary circuit which varies the rate at which the velocity of the fuel in the primary circuit builds up. Alternatively the speed of the pump 6 may be varied. To ensure the attainment of a high enough fuel velocity in the circuit 1 at low engine speeds, a spring- loaded accummulator 95 is provided which absorbs the delivery of pump 6 while the valve 32 is closed and discharges into the primary circuit to supplement the pump delivery when valve 31 is open. The accummulator may be combined with the by-pass valve 101.

Abstract: 605,865. Endless-belt conveyers. SELBY SHOE CO. July 10, 1944, No. 13146. Convention date, May 14, 1941. [Class 78 (i)] A process of manufacturing shoe uppers comprises preparing and collecting the parts making up the uppers, delivering the assembled parts to a first operator indicated on a work sheet initially assembled with the collected parts, indicating by means applied to the collected parts the next station to which they are to be despatched and finally shuttling the collected parts back and forth between stations, as indicated on the work sheet, by means of two conveyer belts travelling in different directions and arranged parallel to one another, linked by a traversing belt at right angles to the said belts and arranged so that both the upper and lower runs of the said belts and traversing belt are available for delivery of the parts in either direction. In the embodiment shown, the arrangement for shuttling the parts backwards and forwards comprises conveyers f, g connected by a conveyer h, the operators being located along the sides of the conveyers f, g and assigned a number corresponding to the particular operation which they perform. All the pieces necessary for the construction of a particular upper are assembled in a box at a table a and a slip is placed in each box showing the sequence of operations to be performed. The box is delivered manually to the operator first required to work on this particular upper, e.g. operator 2, who, having completed the operation, passes the box to, say, operator 3 by placing it on the top run of conveyer f. This operator removes it, performs his operation and then returns it to the belt for the next operator, placing it on the top or. bottom run of the conveyer depending on the position of this next operator. Where necessary, the boxes are transferred from conveyer f to conveyer g by the conveyer h, the boxes engaging members d at the transfer points. The destination of a box is clearly indicated by a coloured flag, each operator having a complete set of these flags.

Title: A system for alleviating the effects of gusts on aircraft
IPC: G01M9/06
Filed: 1957-04-25
Abstract: 813,297. Alleviating gust effect on aircraft. PENNSYLVANIA FRANKLIN INSTITUTE, STATE OF. April 25, 1957 [May 7, 1956], No. 13161/57. Class 4. Means for alleviating the effects of gusts on an area of an aircraft equipped with lift adjusting means, comprises a plurality of gust detectors supported on the aircraft at a plurality of fore-and-aft stations and distributed spanwise, means responsive to airspeed for selecting a variable proportion of the signal from each device and combining the selected proportions, and means to actuate the lift adjusting means in response to the combined signal. Fig. 1 shows an aircraft equipped with a gust detector 14 mounted on a probe 17 at a station X N  ahead of the wing tips and with two detectors 15, 16 on probes 18, 19 at a distance X w  ahead of the wing tips. Each detector, Fig. 2, is coupled to a transducer 21, 22, 23 and amplifier 24, 25, 26 energizing a potentiometer 27, 28, 29. The slides 31, 32, 33 are adjusted by the output shaft 37 of an airspeed responsive servo 38 and are connected so that if slider 31 selects a proportion p of the output of amplifier 24, the sliders 32 and 33 select a proportion 1-p of the output of amplifiers 25 and 26. An amplifier 45 is energized from the three slides and a feed back signal, over resistors 41, 42, 43, 46 of resistance Ro, 2Ro, 2Ro, Ro respectively so that the output is pe N  + (1-f) (e L  + e R )/2 where e N , e L  and e R  are proportional to the gust effects at detectors 14, 15 and 16 respectively. This output is used to actuate the lift adjusting means, which may be slots, flaps, spoilers, or boundary layer control devices on the wings or tailplane. At a high airspeed, the value of p is one, and gust detection occurs at a station X N  ahead of the wing tips. At a low airspeed, the value of p is zero, and detection occurs at station X w  ahead of the wing tips. At intermediate speeds, the above apparatus interpolates to provide effective detection at intermediate stations. Values of p greater than one may be used to extrapolate and provide effective gust detection ahead of detector 14. A fluid pressure system may be used instead of an electrical system. Signals from gyroscopes, accelerometers, and a pilot's control may be added.

IPC: B42B2/02
Abstract: 131,615. Spiess, G. Oct. 24, 1917. Signature gatherers; sheet separators and carriers.-Signature or sheet gatherers are arranged with the sheet-gathering table and the pile conveyor table side by side but oppositely inclined after the manner of the two sides of a roof. As shown, the gathering-table S is alongside the conveyer 25, and the piles of sheets are transferred from the end of the table S to the conveyer by an intermittingly rotating conical carrier 19 on a vertical shaft. Sheets from each ofa series of piles a are separated by a suction bar A in arms C of a shaft B rocked by a rod H and cam &c., and the separated sheets are taken and deposited simultaneously on the table S by grippers Q<3> on a carriage Q<1> operated by bands O<1>, O<2> passing round guide-pulleys P<1>, P<2> and connected to sheaves on a shaft L rocked by a rack and pinion operated by a cam. The table S is formed of bars and the sheets are moved along it, step by step, to effect the gathering, by a reciprocating and rising and falling rake or carrier which rises through the bars of the table S to engage the sheets, lift them, and carry them forward. At the end of the table S the piles are transferred on to one of two plates 20, 21 hinged to the conical table 19, by a second reciprocating and rising and falling rake device. As shown in Figs. 3 and 8, the plate 20 is in position to receive a pile from the table S, after which the conical table 19 makes a semirotation, the plate 20 being during this movement turned up into the vertical position, as shown by the plate 21 in Fig. 8 so as to transfer the pile on edge to a guide 24. Each pile pushes the previously delivered piles along the guide 24 and on to the conveyer table 25, which may consist of endless travelling bands on rollers 26. The inclined position of the conveyer permits of inspection of the marks on the rear edges of the different sheets or signatures which indicate when they are assembled in proper order.
