Abstract: 189,077. Samburg, M., and Hochman, J. C. May 17,1921. Adding and subtracting apparatus; dash-pots, cataracts, and like devices; differential mechanism; full-stroke mechanism; keyboard interlocks. -Relates to the keyboard and differential mechanism of a key-set and operated adding-machine, particularly adapted for co-operation with a typewriter, as described in Specification 187,266, and consists in an improved formation of these parts, and in means for loading the keys whereby the amount of work performed by each key may be equalized. Means are also described for preventing operation of more than one key at a time, and for ensuring a full key depression at each operation. As shown in Fig. 3, the machine is provided with a single set of numeral keys 9 formed by brackets 12 secured to key bars 10 slidable in grooves 11 in the base plate 6; the bars 10 have projecting tongues 22 at their upper ends which are adapted to co-operate with stepped projections 26 on a differential actuating plate 25 slidable in grooves in the end frame, and formed with racks 28 at opposite ends to engage pinions 31, 32 on the actuating shaft 33. The shaft 33 is controlled by a spring 34 secured at one end to the frame and at the other end to the shaft. The shaft carries a loose sleeve 39 on which is fixed the master actuating wheel 37 for the totalizer, and a driving connection is provided between the shaft and sleeve by means of a oneway clutch 40 and gearing 43, 44, 46, 47. The loading means, which is arranged to resist the movement of the keys prior to their engagement with the plate 25, comprises a control plate 80 disposed in front of the plate 25, and having integral racks 85, 86 gearing through loose pinions 87, 92 on the sleeve 39 and actuating shaft 33 respectively, with pinions 88, 93 on a loading shaft 89. Around this shaft is coiled a spring 94 secured thereto at one end and attached at the other end to a loose pinion 96 which engages a pinion 97 on the shaft 33. Depression of the zero key does not affect the differential actuating plate 25 but the key is adapted to co-operate with the vertical arm 117 of a lever 116 pivoted to the control plate 80 to operate the totalizer shift mechanism. A full stroke mechanism for the keys is provided and comprises a rack 125 on each key with which engages the sharp edge 126 of a pivoted plate 127 extending the width of the casing, and controlled by vertically movable plates 131, 131<1> having tongues overlapping the upper edge of the control plate 80 and offset tongues 133 adapted to raise the edge 126 of the plate 127 out from engagement with the teeth 125 at the end of the movement of the control plate. To prevent operation of more than one key at a time, a plurality of inverted T-shaped members 135 are pivoted to the base plate and co-operate with curved shoulders 139 on the key bars. The arrangement is modified between the " 0 " and " 1 " keys since these are close together; thus a rivet head 142 is mounted on a carrier 140 pivoted in a recess in the front plate 17, the swing of the carrier being limited by the sides of the recess.

Title: An automatic electric selector for controlling at a distance
IPC: G08C19/22
Filed: 1922-07-12
Abstract: 183,131. Chauveau, L. L. E. July 13, 1921, [Convention date]. Addition to 146,336. Selective distant control systems.-In a selector arrangement for closing one of two circuits, a single contact is used, the selection depending upon the duration of closure, in place of two contacts selected by different signals as in the parent Specification. The single contact 1 controls a relay 2, one contact 3 of which controls a second relay 4, and the other contact 11 connects with one or other of the two circuits 12, 13 to be selectively energized according to whether relay 2 is not, or is, energized. Contact 5, when relay 4 is energized, closes a hold-on circuit from - local source (not shown) through a contact 7, which is closed except when a release-magnet 8 is energized. At the same time, a second contact 18 is opened. A relay 14, normally energized, in series with a resistance 15, and in shunt with a condenser 16, holds open contact 19. When contact 18 is opened, the circuit of relay 14 and its battery 17 is broken, but the discharge of condenser 16 through the relay winding maintains relay 14 energized for a period determined by the values of resistance 15 and condenser 16, so producing a predetermined time-lag in the closure of contact 19. Contact 19 connects a current source, not shown, with the selected circuit 12 or 13, as determined by the opened or closed condition of contact 1 at the time contact 19 closes, and also energizes the release magnet 8 which de-energizes relay 4. A simpler form is also described in which a slow-acting electromagnet of ordinary type replaces the time-lag arrangement 14, 15, 16.

Title: Tuning mechanism for radio apparatus
IPC: H03J5/12
Filed: 1947-07-18
Abstract: 624,969. Push-button tuning mechanism. GENERAL MOTORS CORPORATION. July 18, 1947, No. 19255. Convention date, Aug. 3, 1939. [Class 40 (v)] In a push-button tuning mechanism for radio apparatus in which continuous tuning is provided through a clutch, operation of any of the push-buttons automatically affects a clutch disengagement, and removal of a push-button for adjustment purposes causes the clutch to remain engaged. As shown in Figs. 2 and 3, the manual tuning knob 107 operates through worm gearing 67, 99 and clutch plates 69, 83 to drive the spindle 1 of the tuning elements 3. When a push-button 175 is depressed, the rod 327 closes the switch 301 to energize the electromagnet 89 and disengage the clutch plates 69, 83, making the manual tuning inoperative. Simultaneously, the cam 243 is pushed in until it contacts either of the projections 299, which are attached to the sliding racks 289 and 291. Further depression of the push-button rotates the spindle 115 by means of the pinion 121, in a direction dependent upon the setting of the cam 243 until both ends of the cam are in contact with projections 299, at which position the desired tuning point is reached, the tuning elements being driven through the gear-wheels 111 and 77 driving the shafts 47 and 1. When the button is released, it is returned to normal together with the cam assembly by means of the spring 235. Each push-button may be adjusted to the desired station by removing the button 175 which is held in place by a flat spring 215, the adjusting screw 209 being then forced outwards by spring 287. The screw 209 which operates a clamping device retaining the cam 243 in the desired position is unscrewed and the required station tuned in on the manual tuning. The screw is then pushed in and the cam is clamped in position when it contacts both projections 299. With the button 175 removed, no movement of the rod portion 327 occurs to disengage the clutch and by this means the shaft 115 is prevented from rotating during adjustment. The driving mechanism for the tuning pointer and the method of illuminating the dial, pointer and station indicators on the push-buttons are also described.

Title: Improvements in colour photographic processes
IPC: G03C7/333
Filed: 1944-10-07
Abstract: 599,377. Colour photography. KODAK, Ltd. (Eastman Kodak Co., and Hanson, W. T.). Oct. 7, 1944, No. 19264. [Class 98 (ii)] A colour photographic process uses as sensitive material a multilayer material, one or more of the emulsion layers containing a colour coupler which gives a subtractive colour on coupling development, and is itself so coloured that it absorbs light of the colour undesirably absorbed by the subtractive colour to give a colour corrected record. The multi - layer material may comprise a support, a redsensitive silver halide emulsion layer containing a coupler yielding a cyan dye image, e.g. 5-(N- benzyl N - naphthalene sulphonamino) -1 - naph - thol dispersed in ethyl N : N-di-n-butyl carbamate, a green sensitive layer containing, e.g. 1 - phenyl - 3-n -pentadecyl- 4-p-methoxyphenyl - azo-5-pyrazolone which is yellow and yields a magenta image upon development, a yellow filter layer of colloidal silver and a bluesensitive layer containing N-(4-benzoylacetaminobenzenesulphonyl) - N - benzyl - m - toluidine dispersed in ethyl-benzyl malonate. After exposure, the material is developed in a solution containing 2 - amino - 5 - diethylaminotoluene hydrochloride, sodium sulphite (anhydrous), sodium carbonate, potassium bromide and water. The green-sensitive layer will contain a magenta negative image and a yellow positive image. The red sensitive layer may also incorporate a coloured coupler, e.g. 4-(benzeneazo) - 5 - (N - # -. phenylpropyl - p - - sec - amyl - benzamido)-1-naphthol) which is included with ethyl N : N-di-n-butyl carbamate and triiso-propyl naphthalene sulphonate in the preparation of the emulsion. The multi-layer negative can be printed on to normal multilayer printing material. Instead of introducing a preformed coloured coupler, the sensitive layer containing the colour coupler may be treated with a diazonium salt prior to colour development. The diazo coupling may be carried out when only the red sensitive layer or the red and green sensitive layers have been coated; or before or after exposure. The conditions may be regulated so that only the coupler in one layer is converted to a coloured derivative. In a specific example, a green sensitive layer containing as coupler 1-(p-tert.- butylphenoxyphenyl) - 3 - [a - (p - tert. - butyl - phenoxy) - propionylamino] - 5 - pyrazolone is treated after exposure but before development with a diazonium solution prepared by diazotising anisidine with sodium nitrite and conc. hydrochloric acid, destroying excess nitrous acid with sulphamic acid and sodium acetate. Colour couplers described in Specifications 586,211, 598,174 and 598,657 may be used. Specifications 475,784, 475,786, 517,416, 524,554, 524,555, 541,589, 553,196, 553,229 and 553,230 also are referred to.

Abstract: 837,671. Eccentrics. UNION SPECIAL MACHINE CO. June 22, 1956 [July 5, 1955], No. 19353/56. Addition to 741,202. Class 122 (1). [Also in Groups VII, XXIV, XXV and XXXIV] In a sewing machine an adjustable eccentric unit for imparting a variable stroke to a pitman 77 comprises an outer eccentric 78 which embraced by the pitman, and an inner eccentric 79 which is journalled on a driving shaft 14 and is embraced by eccentric 78. The overall eccentricity of the unit is varied by turning the eccentrics relative to one another. A disc 80 fixed to shaft 14 is keyed by a pin 81 to eccentric 78. A spring 82 interposed between eccentric 78 and a flange 83 on eccentric 79 biases a friction element 84, fixed to flange 83, against disc 80. A housing 85, secured to disc 80, has a flange 85a engaging a shoulder on eccentric 78. An arm 86 extends radially from flange 83 through a slot in housing 85, and a spring clip 87 abuts at its ends against the opposite sides of arm 86 to cover the portions of said slot not occupied by arm 86. To effect adjustment, a cap 90 is pressed inwardly against spring bias to move a plunger 88 into engagement with a notch in arm 86. Eccentric 79 is thereby held against rotation, when eccentric 78 may be turned to the required extent by rotation of a hand wheel 18. A fixed pointer 94 co-operates with a scale 93 carried by a driving pulley 17 to indicate the overall eccentricity.
