Title: Improvements in or relating to control devices
IPC: G05D23/185
Filed: 1956-09-26
Abstract: 837,675. Linkwork. MINNEAPOLISHONEYWELL REGULATOR CO. Sept. 26, 1956 [Sept. 29, 1955], No. 29394/56. Class 80 (3). [Also in Group XXXVII] A condition responsive device, particularly a thermostat, has its sensing means arranged to actuate two control devices such as switches through a lever biased into contact with an output member of the sensing means and the point or range of operation of the switches is determined by the engagement of the lever with either or both of two adjustable abutments. In Fig. 1, a spring 22 biases the lever 10 into engagement at 14 with a rod 15 on the sensing means 16 and with two fixed contacts 28, 29. As the rod 15 is moved upward the lever pivots about the axis 28-29 until it engages the adjustable abutment pin 26 when it starts to pivot about the axis 26, 28 away from the contact 29, and toward the abutment 25. After engaging the latter the lever pivots about the abutments 25, 26 away from the contact 28. Should the sensing means 16 collapse the lever 10 moves the other way and will engage an adjustable abutment 30 to pivot about 28 and 30 until it engages another adjustable abutment 31 when it pivots about 30, 31. With 14, 26 and 29 in alignment and 14, 25, 28 in alignment adjustment of 26 will have no effect on the condition value separating lever 10 from 28, and adjustment of 25 will have no effect on the condition value separating lever 10 from 29. In Figs. 2 and 3 the lever 110 is biased by the spring 122 against abutments 125, 126 and the end 114 of a rod 115 on a diaphragm 117 of a chamber 121 connected to a temperature sensing bulb (not shown). The abutments 125, 126 are adjusted to set the temperatures at which the lever 110 will operate micro-switches 128, 129. If the diaphragm 117 ruptures the spring 122 will rotate the lever 110 about the actuators of the switches 128, 129 until it engages a screw 130 when it will pivot about axis 129, 130 and leave the actuator of switch 128. When used to provide thermostatic control of domestic forced warm air furnaces, the fan switch 129 " makes " and the limit switch 128 " breaks " on temperature rise.

Title: Improvements in the feeding and opening of collapsed cartons
Inventor: ROSE ALFRED GERMAN
IPC: B31B5/80
Filed: 1956-09-27
Abstract: 846,891. Setting-up collapsed cartons. ROSE BROS. (GAINSBOROUGH) Ltd. Sept; 26, 1957 [Sept. 27, 1956], No. 29473/56. Class 94(1). Collapsed cartons 1 are removed in succession from a magazine 2 by a reciprocating suction nozzle 3 and fed through rollers 7 and between side guides 8 so that the rear edge of each is engaged by a pusher 11 on a conveyer 9. The latter positions each carton for engagement by one of a series of sets of suction nozzles 12 carried by a rotatable member 13 operated continuously in synchronism with the conveyer 9, the nozzles engaging the carton on the forward side of a longitudinal score line so as to leave the position 16 of the carton on the other side freely extending rearwardly. As the carton is carried round by the member 13, cam-operated arms 19, pivoted to the member, engage the portion 16 and cause it to pivot about the score line so as to open the carton and partially recollapse it in the opposite direction. The suction nozzles 12 release their grip as the carton is engaged by a pusher 22 on a conveyer 17 which moves it between inclined guides 21 to complete the recollapsing movement. The cartons are finally transfered in succession to the pockets 25 of a delivery conveyer 23 by cam-operated arms 26 on a rotatable member 24, each carton opening automatically as it leaves the guides 21 due to its inherent springiness and frictional engagement with a side guide 20 of the conveyer 23.

Title: A process of working up acid resins, obtained from the refining of mineral oil derivatives, into neutral bitumens
Filed: 1925-11-26
Abstract: 254,674. Wilhelm, F. Nov. 26, 1925. Pitch.-Acid resins obtained in refining mineral oil derivatives are worked up into neutral bitumens suitable for street paving by reducing the sulphuric acid therein to sulphur and water by means of sulphuretted hydrogen which is introduced into the resins, or produced therein by adding sulphur which reacts with the hydrocarbons present. The acid resin may first be heated, e.g. by steam or direct firing, and agitated, and the sulphuric acid which separates removed, approximately 1.3 per cent remaining. The heating is continued up to about 130‹ C. to concentrate the remaining acid, and the sulphuretted hydrogen then introduced into or produced in the resin to reduce the acid still present. The sulphur produced by the reduction reacts with the hydrocarbons present to produce more sulphuretted hydrogen, a cyclic process being obtained which ceases only when a neutral bitumen has been produced. The hardness of the bitumen produced can be controlled by determining the amount of acid left in the resins after refining and prior to the sulphuretted hydrogen treatment. By addition of crude oil distillation residues of somewhat higher boiling point, the nature of the bitumen produced can also be regulated.

Title: Improvements relating to electric resistance spot-welding machines
IPC: B23K11/11
Filed: 1959-09-03
Abstract: 925,167. Welding by pressure. BRITISH FEDERAL WELDER & MACHINE CO. Ltd., and F. T. TRIBE. Sept. 1, 1960 [Sept. 3, 1959], No. 30116/59. Class 83 (4). The head of an electric resistance spot-welder has an electrode holder carried by a reciprocating slide, a device for holding the slide against movement at a plurality of spaced positions, each corresponding with a weld spot and switch means actuated by the holding device to control the welding current to the electrode. A welder comprises a base 10, pillars 11 carrying a head 12 and a frame 13, with guide ways 14 for a slide 15, suspended from the head 12. A pneumatic cylinder 16 is secured to the frame and its piston-rod 17 is connected to the slide which carries a pair of holders 20 for fluid-operated electrodes 21 arranged above a table 22 on the base, carrying studs 23 connected with the electrodes 21 to a transformer. The slide has two sets of sideby-side ratchet teeth 27a, 27b which overlap and are spaced apart and a pair of pawls 28a, 28b for engaging the teeth are carried in the frame, each being coupled to a piston 30 urged downwardly by springs 32. Compressedair may be supplied to raise the pawls against the springs. The pawls are recessed to receive the heads of Y-levers 36, 37, between whose limbs are arranged arms 38, 40 of switches 39, 41, the switches being closed when the pawls are fully lowered and opened when the pawls are raised, one switch being open when the other is closed. In operation, with the electrodes initially over the first and fifth studs 23, with pawl 28b engaging a tooth 27b and switch 39 is closed, the control circuit including switch 39 allows current to flow to the electrodes. The electrodes are lowered, the welds effected and the electrodes raised. Air is supplied to lift the pawl 28b and air is delivered to cylinder 16 to move the slide 15 to the right, the pawl 28a being urged to engage a tooth 27a and causing switch 41 to close to allow current to the electrodes. The second pair of welds is then made. When all eight welds have been made the slide is retracted to the start position. A switch 42 controlling the supply of current to the electrodes is closed by a stud 45 when the slide is retracted and is opened by stud 44 when the slide is fully advanced so that during retraction current cannot be supplied. The weld spots may be at the same or different distances apart and the welds may unite pairs of panels in a vehicle door, trunk lid or floor. In order to provide weld spots in a cranked line three holders 20, Fig. 5, are provided, one for each section of the line, coupled together at 55 and the first holder being moved by the piston 16. One of the holders has the pawl-and-ratchet device. In a modification, a pair of holders are connected to move along a slightly curved path. The holders may carry two or more electrodes.

Title: Improvements in and relating to thermionic devices for use as amplifiers, relays, detectors, and the like
IPC: H03F3/02
Filed: 1919-12-03
Abstract: 162,710. Taggart, J. Scott-. Dec. 3, 1919. Thermionic detectors wave detectors. - In-- coming energy is caused to vary the grid potential of a triode tube by altering the conductivity of a high-resistance body inserted in the grid circuit. One such resistance may be glass maintained at a temperature just below that at which it becomes conducting. The current in the input circuit raises the temperature sufficiently to allow' the potentive source of electromotive force inserted in the grid circuit to be applied to the grid, through the glass resistance, and thereby to vary the output or plate current; or a local relay circuit is brought into action by the received impulse and raises the temperature of the glass beyond the critical point. As shown in Fig. 2, an imperfect coherer R<1> forms the resistance device. Normally it shields the grid G from the source of the potential E; but the reception of electromagnetic impulses in the aerial circuit L, L<1> causes the coherer to become conductive, whereby the potential of the source E is transferred to the grid. In the modification shown in Fig. 3, a second thermionic device A<1> forms the variable resistance. Electromotive force to be amplified is applied across the grid G<1> and filament F<1> of the valve A<1>, thereby varying the resistance of the plate-filament path of the valve, the whole of which lies in the grid-filament circuit of the valve A; the battery B<1> corresponds to the source of potentials E in Fig. 2. The valve A<1> may be given a high initial resistance by connecting the grid to the negative end of a battery x inserted in the grid circuit. According to the Provisional Specification, the high resistance body may be one sensitive to ionizing agents, such as ultra-violet light rays; or the grid of a triode valve may be connected directly to the plate through a body which has normally infinite resistance but which can be made appreciably conductive.

Title: Improvements in gear cutting machines
IPC: B23F1/06
Filed: 1934-10-22
Abstract: 424,826. Feed mechanism for gearshapers. SCHMITT, W., 5, Bismarckstrasse, Ettlingen, near Karlsruhe, Baden, Germany. Oct. 22, 1934, No. 30284. Addition to 399,001. [Class 83 (iii)] Feed mechanism for the gear - shaping machine described in the parent Specification is provided with improved means to prevent engagement of the depth feed drive for the cam 8 during the operation of the rotational feed drive and vice versa. The cam 8 has a concentric projection which coacts with a lever 10 to lock the change-over lever 29 to maintain the depth feed drive clutch 9 in engagement at the required time, Fig. 2. When the depth feed is completed the lever 10 moves to a position wherein the projection 10<a> is withdrawn from the lever 29 so that the lever cannot be locked in the position for depth feed at any time during the rotational feed. In a modification, Fig. 6, the lever 10 has an extension 53 which during the rotational feed coacts with a pin 54 and prevents any movement of the lever 29. The arm 17 of the ratchet mechanism is pivoted to an arcuate arm 42 which carries the feed pawl 14 and the control lever 29 is connected to a rod 44 terminating in a conical portion 43. When the depth feed is in operation, Fig. 2, the rod 44 is positioned so that it tilts the lever 42 and holds the pawl 14 out of action but when the rotational feed is engaged the conical part 43 allows the arm 42 to move so that the pawl becomes operative. When a rod 45 is moved axially to stop the machine, a lever 46 engages the arm 42 to withdraw the pawl 14 as shown in Fig. 4, and at the same time disengages a ratchet pawl 49. The cam 8 can then be rotated in either direction by a hand crank applied to the shaft 50 for resetting the parts to cut a fresh blank.
