Abstract: 702,173. Stall warning devices for aircraft. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 27, 1952 [June 27, 1951], No. 15304/51. Class 4 A stall warning device for an aircraft comprises a main control column having a handle or grip adapted to be held by the pilot, said handle or grip being agitated relatively to the remainder of the control column by means operative in response to a stall detector, whereby the agitation of the handle or grip can give the pilot a tactile warning of impending stall conditions. A hollow control column 2 comprises a diaphragm 7 to which is secured the outer casing of a flexible drive 3 which extends outside the column for connection to an electric motor (not shown). The drive shaft 10 is keyed to a cam 11, supported on a thrust race 12, the cam being in engagement with a further cam 13 attached to the lower end of a tube 14 which carries a handle 1 and is urged downwardly by a spring 19. A peg 15 secured to the column engages a slot 16 in the tube 14 to prevent the latter member from rotating. The electric motor is associated with a stall detecting device so that when the motor is energized it will cause the handle 1 to oscillate and give a warning of stalling conditions. A further embodiment describes the application of the invention to a spectacle type control column. The handle may perform rocking or gyratory movements.

Title: Improvements in sewing machines
IPC: D05B21/00
Filed: 1970-04-01
Abstract: 1300621 Sewing HER MAJESTY INDU STRIES Inc 1 April 1970 15498/70 Heading DIG  Feeding by movement of stitch forming apparatus; frames; machine bridging work. The upper and lower stitching instrumentalities 20, 22, are movable in unison along two axes X, Y, in the same plane and are rotatable in unison about an axis Z perpendicular to the plane. To this end the units 20, 22 are each separately mounted on cross slides (Fig: 2-5 not shown) and driven in the appropriate directions in the plane by motors driving lead screws, further motors 38, 62 rotating the units in unison about the stitching axis. The motors may be controlled by the logic system shown in Fig. 7. A photo-electric cell 50 mounted on a circular presser foot detects the edge of the fabric to be stitched and provides stepped inputs to the motors 38, 62, by means of the multi-vibrators 150, 148 and components 142, 144, 146, 152, 154, 156, 158, 170, 172. The units thus turn parallel to the work edge, displacing the sine/cosine potentiometer 42 which provides appropriate signals to the X axis motors 98, 116 and the Y axis motors 82, 104. Zero detector devices 176, 178 supplied from the potentiometer brushes 136, 138, detect a zero signal therefrom as the outputs pass through zero and reverse the polarity of the supply to the X, Y motors accordingly. A Schmitt trigger network 188, receiving a signal from a needle drive shaft when the needle is in the work, then supplies a signal to the NOR gates 184, 186 connected to the motor supply circuits to prevent X, Y motion when the needle is in the work. Where the stitching is to be controlled by a tape or programme a servo drive (Fig. 10 not shown) is substituted. The servo drive includes tacho feed back and selsyn units (300, 302). It is stated that the machine may be supported within rings or half rings (380, 382, Fig. 16 not shown) when rotation about and movement along all three axes X, Y and Z permit sewing along any three dimensional compound curve. Using air; machines designed for special goods; seams; feed by belts. The specification describes the sewing of pants and skirts (Fig. 11 not shown) fed to the stitching area by belts (328); of collars and cuffs (Fig. 12 not shown) brought to the sewing area by clamps (338) or, (Figs. 13, 13A not shown) stitched from a number of superimposed plies subsequently cut out by a die not shown; of small parts sewn to larger parts (Fig. 14 not shown). The Specification also states that cloth workpieces may be sewn to a paper support or belt which is stripped away automatically after the sewing operation. Air jets (326, Fig. 11 not shown) may be directed against the bottom of the workpiece to maintain a slight tension therein.

Title: Improvements in paper feeding, cutting, folding, delivering and stacking machines
IPC: B65H33/14
Filed: 1925-11-14
Abstract: 263,404. Brewer, G., (Independent Paper Mills, Inc.). Nov. 14, 1925. Delivery apparatus.- The machine described in Specification 264,627 for cutting paper sheets from a web, and folding them to form paper napkins and similar articles, is provided with mechanism for delivering the folded sheets in counted batches comprising a pair of oppositely-rotating drums 109, 114, Figs. 10 and 11, having a series of blades 110 fixed thereto which co-operate to receive the sheets singly from the machine and deposit them in a pile on supports 134 actuated to drop the pile when a predetermined number has been collected. The blades 110 are curved at 113 in the direction of their rotation so as to guide the sheets towards end rings 119 on the drums, and are gapped at two places 111, 112 in their length to receive fixed vertical bars 128, 130 which are spaced apart a distance equal to the width of the sheets and position them laterally. The supports 134 are formed as angularly-bent rods and are carried by shafts 132 actuated by springs 135 so as to retain the supports in their normal position and coupled together for simultaneous movement by a connecting rod 144 and cranks 141. A stub shaft 146 journaled in the machine frame adjacent to one of the shafts 132 carries two hubs 148, 149 having two series of radial pins 151, 152 respectively and maintained in their relative positions on the shaft 146 by the pressure of a spring 150 and a removable head 147. The pins 151, 152 are engaged during each revolution of the drum 109 by a stop 153 on the disc 119 and a radial pin 123 on the shaft of the drum 109 respectively, the arrangement shown being such that for each revolution of the drums 109, 114 the shaft 146 makes one-fifth of a revolution. A projecting pin 154 is carried by one of the radial pins and engages once during every revolution with a trip arm 155 on the shaft 132, so as to tilt the supports into the position shown dotted, Fig. 11, and drop the pile which has collected thereon. As there are ten blades 110 on each drum, ten sheets are deposited on the supports 134 for each revolution of the drums, and therefore, in the arrangement shown, the sheets are delivered in piles of fifty. In order to prevent a sheet from missing the supports 134 if they do not return sufficiently quickly to their normal position after dropping a pile, auxiliary support arms 157, Fig. 14, are provided, these arms being fixed to shafts 156 carried by the drums 109, 114. A bell-crank lever 169 is secured to one end of each shaft 156 and has rollers 170 171 on the ends thereof engaging cams 167, 168 fixed to the framing so that the arms 157 are horizontal as they approach one another, Fig. 14, and remain so as they recede from one another and until the supports 134 have returned to their normal position. A current of air from a pipe situated over and between the drums 109, 114 plays on the sheets as they are being stacked so as to prevent the outer folded sections of each sheet from opening.

[Class 100 (i).] Feeding webs; cutting-apparatus.-In connection with a machine for printing a plurality of impressions on a continuous band or tape as described in Specifications 404,408 and 404,534, a feeding mechanism is provided comprising a primary feeding device having means for gripping the band and feeding it through the machine for the first of the said operations, a perforating device, and one or more secondary feeding devices having means for positively engaging the perforations of the band or tape to feed it through the machine for the second and successive operations. The web 27 is fed forward intermittently by a reciprocating gripper 94, Fig. 4, which is adjustably mounted in the arm 93 of a bell-crank lever 92 pivoted to a reciprocating carriage 88 which moves on a guide 87, Fig. 1, and is frictionally hold in engagement therewith by means of adjustable spring-pressed shoes 98<1>. The carriage is reciprocated by means of a link 85 operated by a crank-arm on a shaft 68 which is oscillated from the printing-machine. As the link 85 moves to the left the gripper 94 is raised and the lever 92 engages a stop 98 on the carriage 88. After the primary feed motion, the tape is perforated by a punch actuated by a lever fitted to an arm 109, Fig. 1, and operated by a universal joint connection with a lever oscillated in unison with the shaft 68. After the tape is perforated it is passed down under the machine and fed back through the machine in the same direction and in parallel relationship to its first course, and a further number of similar loops are formed so that successive operations may be performed on the tape. The secondary feed operations are performed by spring-pressed dogs 73, which are mounted in a reciprocating carriage 64 and engage the perforations produced in the web by the punching-apparatus. The tapes are guided transversely by fixed guides 81, which engage the adjacent edges of two loops of the tape, and by spring-pressed pivoted guides 80, 82 which engage the outer edges of the same.

Title: Method of preparing printed circuits
Inventor: MODJESKA RICHARD SCOTT
IPC: H05K3/20
Filed: 1967-04-05
Abstract: 1,116,299. Method of preparing printed circuits. UNITED-CARR Inc. 5 April, 1967, No. 15566/67. Heading H1R. In a method of preparing printed circuits a transfer plate 1, Figs. 4, 5, which is to form a temporary base for the circuit, is coated with a separable thin film or so-called parting layer 2 comprising an admixture of powdered electrically conductive material with an organic solvent, soluble resin or wax. A negative resist pattern (3), Fig. 2 (not shown) is laid on the layer 2, e.g. photographically, and a copper circuit pattern is then formed preferably electrolytically, the conductive layer 2 acting as a common cathode during plating. The resist is then removed by a solvent which will not attack the parting layer, leaving the arrangement shown in Fig. 4. A permanent insulating base 5 is now molded against the exposed surface of the circuit and parting layer, and finally the transfer plate 1 and layer 2 are removed leaving a conductive pattern flush with its insulating base, the assembly having a smooth surface which conforms to the surface of the transfer plate on which it was formed. The assembly may be used as a commutator or as the fixed contacts of a slider switch. The transfer plate 1 may be of glass, stainless steel or synthetic plastics, and the "parting" layer 2 may be a homogeneous dispersion of graphite or powdered metallic conductor in beeswax, silicone wax, synthetic hydrocarbon, carnauba, or in organic solvent soluble synthetic resins or waxes such as polystyrene, polyvinyl acetate etc. The permanent base may be any suitable curable insulating substance such as Bakelite (R.T.M.) and other phenolic resins, alkyd resins, polyesters, nylon, ureaformaldehyde resins, epoxy resins, melamine plastics or ceramics. The base material is cured in situ by the application of heat and pressure. The " printed " deposit may be metal or a semiconductor such as selenium, germanium, copper sulphide, cadmium sulphide; or integrated circuits of combined semi-conductive and conductive materials may be formed.

Title: Improvements in or relating to the production of photographic colour images
IPC: H01H51/06
Filed: 1953-06-05
Abstract: 739,202. Colour photography. AGFA AKT.- GES. FUR PHOTOFABRIKATION; June 5, 1953 [June 7, 1952], No. 15591/53. Class 98 (2). In the process for introducing colourcorrecting azo dye masks into multilayer silverhalide colour former materials, the material is exposed, colour developed, treated in a combined bleaching and fixing bath, and then treated with a stabilized diazonium compound which is preferably derived from aniline substituted only by halogen or alkyl groups. Reversal procedure by black and white development and re-exposure before colour development may be conducted. A preferred bleaching-fixing bath, use of which together with the preferred diazonium compounds avoids undesirable image formation in the bluesensitive layer, comprises a ferric or cobaltic complex salt of an organic acid of constitution (1) HOOC-R 1 -X-R 2 -COOH or (II) in which X is CH 2 , O, S, or N-R 3  and R 1 , R 2  and R 3  are hydrocarbon radicals which may be substituted, in which case R 3  may also be H, in formula (I) ; and X is N and R 1 , R 2  and R 4  are divalent hydrocarbon radicals which may be substituted in formula (II). Ferric complex salts of amino carboxylic acids containing more than one carboxylic end group per amino nitrogen atom as of Specification 474,082, [Group IV], are especially suitable. In example 1 an exposed silver halide multilayer colour film having a blue-sensitive layer containing 4 - stearoylamino - benzoylacetanilide - 3<SP>1</SP> - 51- dicarboxylic acid, a green sensitized layer containing 1 - (4<SP>1</SP> - phenoxy - 3<SP>1</SP> - 5<SP>1</SP> - sulpho)- phenyl-3-stearyl-5-pyrazolone and a red-sensitized layer containing the 2-methyloctadecylamino - 5<SP>1</SP> - sulphoanilide of 1 - hydroxy - 2- naphthoic acid is colour developed in a specified bath containing N-ethyl-N-#,hydroxyethyl-paminoaniline sulphate, bleached and fixed in a bath containing the sodium salt of ethylenediamine tetracetic acid, ferric chloride and sodium carbonate, sulphite and thiosulphite, and then treated in a bath containing the addition product of diazotized 5-chloro-2- toluidine and naphthalene- 1,5-disulphonic acid to produce a yellow masking image in the magenta colour image layer and an orange masking image in the blue-green colour image layer. In example 2 the coupler in the redsensitized layer is replaced by 21-methyloctadecylamino - 5<SP>1</SP> - sulphoanilide of 1- hydroxy - 4 - sulpho 2 - naphthoic acid, whereby the magenta colour image layer only contains a mask. Example 3 describes reversal processing of the film of example 1 and replaces the diazo compound with the addition product of diazotized 4-chloro-2-toluidine and acetamido-p-sulphonic acid. False colour procedure is indicated. Specifications 602,881, 645,170, 652,953, 665,657 and 701,039.also are referred to.
