Title: Character recording apparatus
IPC: B41J9/10
Filed: 1960-03-15
Abstract: 883,156. Typewriters &c. NATIONAL CASH REGISTER CO. March 15, 1960 [March 19, 1959], No. 9079/60. Class 100(4) A printing mechanism, particularly for producing a magnetic image from a special ribbon containing magnetic ink, has a spring operated hammer inpression mechanism giving a variable impact dependent upon the character selected. - Type wheel setting. The machine is operated by a motor 35, Fig. 5, and comprises a number of type wheels 60 on a shaft 61, Fig. 1. A clutch mechanism controlled by a solenoid 50, Fig. 5, causes rotation of a cam-shaft 56 which by cam plates 86, segments 82, 83, rotates discs 76 differentially arrestable by pawls 87, 88 controlled by solenoids 98, 102 actuated by even and odd number digit keys respectively. The discs 76 set the type wheel through a coupling comprising gears 62 and square shafts 63. The type wheels are aligned by a tooth 34 of an aligner 33 engaging notches of the type wheels 60 when actuated by a cam 103 on the cam-shaft 56. Impression Mechanism. Impression is made on documents placed on a slip table 119 over which a tape is guided from a roll 116 to a roll 121 and is effected by a platen 122 for each type wheel struck by a corresponding hammer 142. Each platen is normally held withdrawn from its type wheel by arms 126 but just prior to the printing these are lowered by a cam on the shaft 56 allowing springs 127 to bring the platen against its type wheel. Hammers 142 have an insert 143 in resilient material 144 and when they strike the platens which have a bevelled end 177 and are loosely mounted, they produce an impact with a considerable dwell and some rubbing action. The striking force is derived from either springs 151 or 156 the former set applying a constant force for set symbols while the latter set apply a force through levers 154, 152, 147, 146 variable according to the type selected. Just prior to the printing when the type wheels have been set a cam plate 103 acts to raise a lever 170 to remove a bail 169 from beneath an arm 160 thus allowing each spring 156 to lower a link 154 until a projection 163 is stopped by a stud 164 located on the ring gear 62 and positioned for engagement when the type wheel is set. The amount of movement of the lever 154 is dependent on the type selected and alters the point of engagement of a pin 153 on a lever 152 and thus the force that will be applied by the spring 156 when striking occurs. During striking the lever 152 becomes inclined to the left so that the spring 156 again raises the arm 154 to return the lever 160 and to allow the cam plate 103 to restore the bail 169. The hammers are returned by a rod 178 actuated by a further cam.

Title: Improvements in or relating to tabulating-mechanisms for typewriters and the like
IPC: B41J25/18
Filed: 1919-04-12
Abstract: 146,637. Etheridge, H., and Bar-Lock Typewriter Co. April 12, 1919. Tabulating-mechanism; tabulating-key actions; carriage-releasing arrangements.-In columnselecting mechanism in which a dog is.raised to graded heights by column-selecting-keys, the dog can be adjusted, in a direction parallel to the travel of the carriage, for denominational tabulating. In the mechanism shown, the dog F is secured to a foot G which can slide on a rod E, carried by bell-cranks C connected to the columnselecting keys D. The dog is connected by a link H to a lever J on a shaft J<1> which is provided with a pointer J<2> arranged over a denominational scale J<3>. The dog is held in the set lateral position by means of a detent such as a ball-catch G', Fig. 2, engaging grooves E<1> in the rod E. The dog consists of an L-section member, one flank being cut away at the top, and the top of the other flank F<2> forming a stop for engaging the stops on the carriage. The flank F<2> passes between a guide K and a rack K<1> and is formed with. a recess F<4> which is normally in register with a rack L. The keys D operate levers D' connected to links P<1> which are formed with slots P<2> engaging a rod C<3> on the bell-cranks C. A carriage-releasing bar O is connected to a bail M having a universal bar M<1> in the path of lugs P, arranged on the links P<1> at graded distances from the bar. The top of the bar O is formed with a shouldered part O<1> which passes through a hole in the rack K<1>. In operation, the dog is set in the required denominational position by means of the pointer J<2> and is then elevated by depressing one of the column-selecting keys D, the bar 0 releasing the carriage when the dog has been elevated. The dog is arrested by the engagement of the shoulder O<1> on the bar 0 with the rack K<1>, the elevation being determined by the amount of lost motion between the universal bar M<1> and the lug P associated with the columnselecting key. In rising, the dog is rocked into engagement with the rack K<1> by the engagement of an incline F<3> on the dog with the guide K, or vice versa; also, the flank F<2> of the dog moves into engagement with the rack L. The guide K and the racks K<1>, L hold the dog rigidly in the set position. In some cases, the dog, instead of being released from the rack K<1> by a rocking movement, is arranged to be depressed below the level of the rack. The bell-cranks C are mounted on a detachable bracket A.

Title: Improvements in and relating to electronic gauging systems
Inventor: HIRST PETER
IPC: G01B7/00
Filed: 1956-03-26
Abstract: 822,182. Electric indicating systems. RANK PRECISION INDUSTRIES Ltd. March 22, 1957 [March 26, 1956], No. 9408/56. Class 40 (1). [Also in Group XL (c)] The radial dimensions of a rotated body are measured electrically by a feeler gauge and compared with a required value, the difference being shown on a cathode-ray oscilloscope together with lines representing the maximum and minimum values of the permitted variation. Different types of error may be analysed in frequency sensitive circuits and displayed separately on the C.R.O. against maximum and minimum values, and the error voltages may be used to operate automatic rejecting mechanism when outside the permitted tolerances. As shown, a nominally round body 1 is rotated by a motor 8 which also drives, via a selsyn link, the deflecting coils 3 of a C.R.O. 2, which are fed with a saw-tooth wave from a time box 12. Variations in the radius of body 1 are sensed by a feeler gauge 10 producing an error voltage which is compared at 11 with a saw-tooth voltage to produce a pulse when the voltages are equal, which is shown on the C.R.O. The sequence of spots thus produced as the test body 1 and the scanning coils 3 rotate synchronously form a trace showing the divergency of the test body from true round. A voltage representing the maximum permissible radius is set up on potentiometer 13 to give via comparator 14 a series of pulses producing a trace of the upper limit of radius, and potentiometer 15 is similarly set to produce a visual indication of the lower limit of radius. The three pulse trains are fed to a gate 17 which is closed between the limiting pulses from potentiometers 13, 15, so that a pulse from comparator 11 outside the limits will pass through gate 17 and operate a rejector 18. The signal from the feeler gauge 10 is also filtered at 19 to determine the mean radius of the test body 1, and is fed to the C.R.O. together with maximum and minimum values of average radius as set upon potentiometers 21, 23, and is also used to control the rejector 18. Special types of errors may be analysed separately by frequency analysis of the error signal in filters 27, 34, 41, the results being compared with upper and lower limiting values for operation of rejector 18. The appratus may be used to examine other than round objects, using either a radial or rectilinear scanning raster.

Filed: 1927-04-06
Abstract: 291,918. V. D., Ltd., and Burrows, R. W. April 6, 1927. Coating ropes and cables.-The cable as it is wound on, or paid out from, a winding drum is oiled by means of a roller which rides on the coils on the drum and transfers lubricant thereto. In the construction shown, a pair of upright arms c and a cross-piece e are mounted on a winch frame supporting a winding drum b. An arm g depending from the cross-piece carries a roller l which is pressed by gravity against the coils of a cable being wound on the drum. Oil from a tank m is supplied to the roller by way of a flexible pipe n and a fixed pipe p with a perforated part p<1>. The arm g, which is in two parts adjujstable with respect to each other, is hooked to a wheeled carriage r which runs on the cross-piece e. When the cable is to be oiled during unwinding, the arm g is swung to engage the coils at the other side of the drum. The roller l is recessed to receive a length of hemp or other absorbent yarn v wound thereon. In a modification, the roller is of convex form with cylindrical or helical grooves. Two oiling rollers side by side may be employed. The invention is especially applicable to the treatment of warps by which a trawl net is hauled in or paid out on a fishing boat.

Title: Improvements in coating machines particularly for coating containers or cans
IPC: B05C7/02
Filed: 1941-07-28
Abstract: 550,933. Coating interiors of containers. CROWN CORK & SEAL CO., Inc. July 28, 1941, No. 9586. Convention date, July 29, 1940. [Class 95] A machine for coating the interiors of containers or similar articles comprises a plurality of article holders mounted for movement along a predetermined path and a plurality of coating devices mounted for movement along at least a portion of that path with the holders, and is characterized by mechanism for moving the holders and the articles into operative relation to the coating devices and for actuating the coating devices as a result of that movement or a continuation thereof, thereby to coat the articles in the holders, the said mechanism being rendered inoperative to move the holders in the absence of articles in the holders, whereby the coating devices associated with empty holders are not actuated. In the machine illustrated, the table 10 rotates on a vertical axis 11, and carries vertical posts 12 upon which the can-supporting assemblies are mounted for vertical sliding movement. The table 10 also supports an annular trough 13 for containing molten wax or other coating material. Opposite each vertical post 12, is a sprayer assembly comprising a cylinder 20, a piston 22, a spring 23, and an upwardly projecting discharge pipe 24 carrying a nozzle 25. The lower reduced portion 12<SP>1</SP> of each post 12 carries a slidable sleeve 31, bracket arm 33, can-receiving chuck 34, and pivoted clamp 41. The clamps 41 are opened and closed by the engagement of rollers 46 with a cam track 45. A second slidable sleeve 55, on each post 12, is raised and lowered once during each revolution of the table 10, by the engagement of a roller 58 with a cam groove 59, and this reciprocating movement is transferred from the sleeve 55 to the sleeve 31 when the toggle mechanism 62, 63 is in the position shown in Fig. 3, thus lowering the can and the piston 22, and causing a stream of liquid wax to be projected upwardly into the interior of the can. When, however, the toggle mechanism is in its other position, with its lower end 75 clear of the block 76, the sleeve 55 is free to reciprocate without imparting movement to the sleeve 31. Cans are carried on a conveyer chain 85, and, at the position 50, are transferred from the clamps 88 to the chucks 34 on the table 10. Adjacent the path of the cans on the conveyer, there is a pivoted feeler 92, which operates the toggle mechanism through the switch 97 and compressed air cylinder 102, in such a manner that upon encountering an empty can holder 88, the coating device associated with that empty holder is rendered inoperative. A pre-heating oven 86, and a wax drain 122, may be provided.

Title: Flame ignition and supervision system
IPC: F23N5/24
Filed: 1974-03-04
Abstract: 1452682 Burners WALTER KIDDE & CO INC 4 March 1974 [12 March 1973] 9666/74 Heading F4T A control circuit for a fuel burner has an electrical energy store means for receiving and storing energy from a source, an energy transfer means responsive to a burner flame detector for transferring energy in the store means to valve means controlling the supply of burner fuel and limit means for preventing sufficient energy from flowing from the source directly to the valve means to actuate it during normal operation. In the circuit energisation of a coil 49 opens the control valve. Coil 49 is connected to an isolation diode 52 and is parallelled by a capacitor 51 and a pulse responsive resistor 53. During positive halfcycles of the source line 44 relative line 41 an energy store capacitor 54 and a spark capacitor 57 are charged via primary winding 61 of a spark transformer 31. When a flame is present on the burner 47 the flame detecting circuit 35 provides a sufficient charge on the capacitor 73 due to the firing of SCR 71 to cause SCR 36 to fire each half cycle which discharges a delay capacitor 22 so that sufficient charge cannot be built up to fire a SCR 24. Firing of the latter causes the valve to open and a spark at the transformer 31 to ignite the burner, which spark is caused on each absence of the flame. Firing of the SCR 36 maintains the valve open due to the discharge of capacitors 54, 57 therethrough. If a flame is not established a delay capacitor 95 is charged and after storing sufficient energy fires a threshold neon bulb 101 which causes SCR 99 to conduct and a drop across resistor 83 so that SCR 24 conducts in a shut-down mode and lock out thermal circuit breaker 45 opens. Bimetallic member 33 also causes shut-down after a predetermined :time if SCR 24 keeps firing due to a flame not being detected. Modifications of the valve control circuit are described (see Figs. 4-6 not shown).
