Title: Automatic weight recording system
IPC: G01G23/18
Filed: 1942-09-01
Abstract: 559,790. Electromagnetic relays. SCHELLENTRAGER, E. W. Sept. 1, 1942, No. 12316. [Class 38 (v)] [Also in Group XVIII] In an automatic weight recording system for scale cars having dumping doors opened by power-actuated means, the recording apparatus is operated by an electric relay circuit established by manual actuation of a power control valve, and means are provided for maintaining the energization of the relay circuit to prevent for a predetermined time the further actuation of the recording mechanism (which actuation would mar the record) if the power control member were repeatedly operated to bang the dumping doors and free the car of its contents. As shown, the car dumping doors are operated by fluid pressure motors 1, supplied and exhausted by operation of four-way valves 4 connected to a reservoir 2. In connection with each dumping door is a relay servomotor 8 controlling a normally open switch 8a. In operation, assuming the car has been loaded, at least one of the valves 4 is manipulated to supply fluid to one end of the motor 1 and open the corresponding dumping door. Before the door has time to open, the servomotor 8 closes the switch 8a and energizes a relay coil 11 to cause a stylus 29 to make momentary contact with the record paper 30. The recording apparatus is of the type such that no further record can be made until the coil is de-energized and again energized. To delay the de-energization, a switch 15 closed by the coil 11, establishes a circuit to maintain the energization of the coil so that if the operator now manipulates the valve 4 to bang the dumping gate the coil is unaffected and no further record is made. The switch 15 also maintains the energization of a coil 18, which, after the lapse of a predetermined time controlled by a dashpot 23 opens a switch 13 and de-energizes the coil 11, all the parts being then restored to their original positions in readiness for the next recording operation.

Title: Improvements in textile article treating apparatus
IPC: D06C5/00
Filed: 1944-06-28
Abstract: <PICT:0584387/IV/1> <PICT:0584387/IV/2> A chamber for treating textile articles comprises remotely-controlled power means for operating a closure for the charging and discharging opening, means operated by the closure when reaching its closed position to initiate operation of a power means for locking the closure in its closed position and means responsive to pressure within the chamber for holding the power on said locking means to keep the closure locked until said pressure has dropped to a predetermined point.  A chamber 12, Fig. 1, for treating polyamide fabrics mounted on forms on a wheeled carriage has a door 14, Fig. 3, slidable up and down in channelled guide members 16 under the action of a pair of pneumatic cylinders 18, each connected to a toothed rack 19 which operates on rack teeth 24 on the door edges through pinions U-shaped clamps 34 are mounted to bear against the door 14 under the action of a pneumatic cylinder 46 linked to a bell-crank lever 3.  The air supply for operating the cylinders 18, 46 controls also a steam inlet valve 49 and a steam exhaust valve 54, and is controlled by a system of valves each operated by an electromagnetic switch.  A cycle of operations is commenced by the operation of an electric switch to cause air to be supplied to the cylinders 18 to close the door 14. When the door reaches its lowest position, a member 86 on a rack 19 operates, through a roller 88, a switch 91 which causes air to be supplied to the cylinder 46 to clamp the levers 34 against the door 14.  In the latter movement the lever 39 operates a switch 96 to cause air to be supplied to open the steam inlet valve 49 and to close the exhaust valve 54.  On reaching a predetermined value, the pressure of steam in the chamber operates a switch 130 to start an electrical timing device, and a switch 100 which ensures that the control means maintains an air supply to the cylinder 46 to keep the door 14 clamped as long as the predetermined pressure is maintained in the chamber.  When the required length of time for treatment has elapsed, the timing device operates to close the valve 49 and to open the valve 54. As the steam pressure falls, the switch 100 operates to apply compressed air to the cylinder 46 to release the clamps 34. The lever 39 then operates switch 96 to apply air to the cylinders 18 to open the door 14.

Filed: 1972-03-16
Abstract: 1420933 Making labels DAVID J INSTANCE Ltd 9 March 1973 [16 March 1972] 12384/72 Heading B8F A continuous reel of self-adhesive labels is formed by successively-feeding labels from a label stack 29 past a pressure-sensitive adhesive applicator 61-64, and then applying the adhesive-coated labels to a continuous web 71 of silicone-coated release paper, which is subsequently reeled. The uppermost label of a label stack 29 is transferred by a reciprocable suction bar 35 on to a perforated rotating vacuum drum 49, which carries the labels past the applicator, through a hot air drying tunnel 65, to a pick-up roller 70 resiliently urging the paper web 71 during its movement between reels 72 and 34 against the drum. The labels are held on the drum surface until they reach the pick-up roller by static vacuum chambers 52, 54, 55 and 56. The label stack is carried on a cable-suspended table 30, which is raised one label thickness for each transfer movement of the suction bar by means of a link and a cable-drum ratchet mechanism 46, 461 coupled to the drive shaft of a cam 44, which effects pivotal movement of a suction bar-carrying bell-crank 38. The adhesive may be applied other than by a roller applicator as shown, e.g. by a screen process, by spraying, or by a doctor blade.

Title: Method and apparatus for Determining Surface Quality
Inventor: ROBERTS JOSEPH IAN
IPC: G01N21/55
Filed: 1966-03-21
Abstract: 1,156,920. Photo-electric surface finish determination. MACHINE TOOL INDUSTRY RESEARCH ASSOCIATION. May 26, 1967 [March 21, 1966], No.12410/66. Heading G1A. In determining the quality of finish of a surface a photo-cell is alternately progressively exposed to and progressively cut off from light reflected off the surface, the photo-cell output wave form thereby indicating whether the light received was a sharply defined beam specularly reflected off a good surface or an ill-defined beam diffusely reflected off a poor surface. The alternate exposure and cut-off of light may be provided by a continuously rotating toothed disc or a slit which repeatedly opens and closes. An indication of the surface finish is given by the maximum amplitude of the second differential of photo-cell output, that is the rate of increase or decrease in light received, or alternatively by a comparison of the maximum amplitudes of the output and its finish differential, that is a measure of the specularly reflected light as a proportion of the total light.

Filed: 1934-04-25
Abstract: 436,736. Absorption refrigerating systems. CARPMAEL, A., 24, Southampton Buildings, Chancery Lane, London.-(Ges. fur Drucktransformatoren Koenemann-Transformatoren Ges.; 170, Mullerstrasse, Berlin) April 25, 1934, No. 12491. [Class 29] In a continuous absorption refrigeration process in which the liquid absorption agent comprises one or more anhydrous. non-volatile inorganic salts and a liquid refrigerant, the proportions of the materials are such that the vapour pressure of the absorption liquid at 70‹ F. is lower than the vapour pressure of the refrigerant at 0‹ F., and the temperature difference between the evaporator for the refrigerant and the absorber amounts to 70‹ F. or more. Suitable salts comprise anhydrous perchloric acid salts of the alkali metals, metal halogenides such as zinc chloride or bromide, aluminium chloride, magnesium iodide, potassium bromide, lithium chloride ; other lithium salts, such as the nitrate, are also suitable. The refrigerant may comprise ammonia or amines. Ammonia vapour streams from a generator 1, supplied with lithium nitrate ammonia, at a pressure of 170lbs. per sq. in. and a temperature of 320‹ F., to a water-cooled condenser 3, from which the liquid ammonia proceeds to an evaporator 6 through a throttle valve 5. Refrigeration is effected at 58‹ F., and the ammonia vapour is absorbed in an absorber 8 at a temperature of 86‹ F. The ammonia-rich liquid is returned to the generator through a heat-exchanger 11 and a throttle valve 13 and the liquid poor in ammonia is returned to the absorber through the pipe line 14. A cooling water temperature of 68‹ F. may be used. If the latter corresponds to 104‹ F. the refrigeration temperature is raised to -4‹ F. In a modified plant using zinc chloride diammonia, the condenser and evaporator are connected in parallel across a heat - exchanger wherein ammonia escaping from the latter is reheated by ammonia coming from the generator, before being absorbed in the absorber. The latter absorbs at such a high temperature that the heat of absorption may be utilized in a separate vessel for the production of pressure steam. An ammonia vapour turbine may be arranged in parallel with the plant to regulate the load. Reference has been directed by the Comptroller to Specification 358,844.

Title: Improvements in or relating to coating devices
IPC: B32B17/10
Filed: 1930-04-23
Abstract: <PICT:0353080/III/1> <PICT:0353080/III/2> In apparatus of the type in which a horizontal moving plate is coated by means of a transversely reciprocating spraying device, parallel bands of liquid are laid across the plate by imparting to the spray nozzle a component of motion in the direction of movement of the plate and also, at the end of each traverse, a movement in the opposite direction.  In one construction, the component of motion in the direction of the moving plate is obtained by tilting the nozzle, and movement in the opposite direction is effected by means of a spring released by a trigger mechanism.  A nozzle arm 21, Figs. 1 and 2, pivoted at 22 and oscillated by a connecting-rod 43, carries a striker 44, which, when the nozzle-arm 21 reaches the end of its travel, rocks a trigger 34 against the action of a spring 38, releasing it from a catch-plate 39, thus causing a shaft 31 to rotate, through links 29, 30, a rocking bar 27, pivoted at 28, under the pull of a spring 42 acting at its opposite end.  The rocking bar 27 carries with it a fork 26, which tilts a nozzle 17 carried by a clamp 24 to its extreme backward position.  As a nozzle-carrier 18, pivoted to the nozzle-clamp 24 and sliding on guide-rods 19, 20, is traversed across the plate 11 by the nozzle-arm 21, the forked rod 26, following the upwardly-inclined rocking bar 27 directs the nozzle 17 so as to project the spring in a direction progressively in advance of its starting position.  In another construction, the forward movement is imparted to the nozzle by moving it bodily and the backward movement is effected by a cam-operated mechanism driven in synchronism with the nozzle-carrier. An arm 56, Figs. 5 and 7, oscillated about a pivot 57 by means of a motor 46 through gearing 47, crank arm 49, coil 51, and crosshead 53, is provided with an extension 58 moving in a guide 59 swivelled on a second crosshead 60 sliding on guide-rods 61.  Horizontal rods 62, sliding freely in the guide 59, carry at their outer ends a holder 63 of a spray-gun 64 and are connected at their inner ends by a cross-bar 72, which has swivelled thereon a yoke 74 in which is supported a roller 75, held in contact with a pivoted track 77 by means of a tension-spring 76.  At the end of each transverse movement of the spray gun 64 the angular position of the track 77 is shifted by the movement of a connecting-rod 87 bearing a roller 86 engaging in a stepped groove 84 of a cam-wheel 79, which is rotated by the motor 46 through gearing 83, 81 and shaft 80, and the path of the spray gun 64, which is necessarily parallel with the track 77, is likewise shifted in angular position.  The machine may be used in the manufacture of laminated glass for supplying liquid coatings of uniform thickness to the glass sheets. <PICT:0353080/III/3> <PICT:0353080/III/4>
