Title: Improvements in and relating to sheet feeding devices
IPC: B65H5/24
Filed: 1937-07-05
Abstract: 491,747. Feeding sheets. SPEISS, G. July 5, 1937, No. 18694. Convention date, July 6, 1936. [Class 100 (i)] A machine for feeding blanks or sheets to printing, folding, and like machines is constructed so as to be capable of feeding the sheets in timed or untimed relation to the machine and in overlapped relation or with the individual sheets one behind the other. As applied to a machine in which the sheets can be fed first to a reciprocating blade folding machine 3 and then to a buckling folder 2, or can be fed direct to the buckling folder 2, the feeding is in timed relation in the former case only. A pivoted transfer table 4 can be adjusted to feed the sheets either direct to the table 5 of the folder 3, or to the feeding rollers of the folder 2. The sheets are fed from a fanned-out pile on a lower feed table 9 formed by advancing sheets from an upper table 6 by a roller 7 and guide bands 8, and the sheets are finally fed to the table 4 by means of a conveying roller 26, a reversing roller 13, and bands 14. The separation of the sheets is effected by means of a suction roller 15 arranged at the front of the fanned-out pile, or if overlapping feed is required by means of a suction roller 19 which is mounted in bearings carried by brackets 20 which are adjustable longitudinally of the pile. The roller 19 is driven from the roller 15 by means of worm gearing 16, 18 and a shaft 17 splined to the gear 18. The conveying roller 16 is driven from a main control shaft 27 by means of changeable gears 28, 30, or 29, 31, the latter being used for overlapping feed. The suction in the rollers 15, 19 is controlled by valves operated by a cam 60 on the shaft 27, but for untimed feed the suction operates continuously. The roller 13 is driven from the shaft of the roller 26 by means of gears comprising a gear 32 free on the shaft 27, and this drive is continued by gears 34, 35, 37, to the band roller 36 of the conveying bands on the table 4 and to the other band roller 45 by bevel gearing 38, 40 and gears 42, 43, 44. The conveying and inclined feed rolls of the buckler folder can be driven by changeable gearing from the bevel gear 40 at one of three speeds.

Filed: 1924-08-06
Abstract: 220,620. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Aug. 14, 1923, [Convention date]. Vacuum tubes.-In order to facilitate the removal of occluded gas from an electrode in a tube which is continuously or temporarily filled with gas, one or more auxiliary electrodes are arranged in proximity to the electrode, or the electrode may consist of insulated parts, so that a gaseous discharge may be passed between the auxiliary and main electrodes or between the parts of the main electrode; the auxiliary electrode is inoperative during normal working. The arrangement is applicable, to tubes in which the electrodes are spaced widely apart as in Moore tubes. The areas of the main and auxiliary electrodes should be approximately equal. In the Moore tube shown in Fig. 1. the electrode at one end of the tube 2 consists of semi-cylindrical parts 3, 4 with separate leads 5, 6. A discharge is passed between the parts in a filling for instance of argon at a pressure of 10 mm. of mercury, and the fining and liberated gas are removed; the operation may be repeated several times. During normal working the parts 3, 4 act as a single electrode. In a rectifying tube a straight incandescent wire cathode is surrounded by an anode consisting of two parts shaped as shown in Fig. 1. In another arrangement a cylindrical main electrode is surrounded by a cylindrical auxiliary electrode, or conversely, and during working one only of the electrodes is operative.

Abstract: 580,906. Feeding webs. JONES, K. W. Oct. 3, 1944, Nos. 18874/44 and 24095/45. [Class 100 (i)] In a reel-fed printing machine having a suction roller to draw the web through the machine, means are provided for intermittently rotating the suction roller. As shown, the shaft 11, driven by the chain 10, drives the rollers 1, 2 of a rotary printing unit continuously through gearing 13, 15, and a suction roller 5 intermittently through a mutilated gear 12 and the gear wheel 16. The gearing is synchronised so that when the web 4 is being moved by the suction roller 5, a stereo 3 on the roller 1 prints on the web, but when the web is stationary, a part of the roller 1 having no stereo is opposite the web. A platen printing unit 6, 7 prints when the web is stationary and secondary operations, such as cross-perforating or punching may be performed. If the units for these operations are placed behind the suction roller 5, an additional continuously rotating pull-through roller, suction or otherwise, is used, causing such a pressure as to allow the web to slip on it when the suction roller 5 is stationary. The surface speed of this roller may be greater than that of the web when moving. Specifications 517,534, [Group XXIV], 559,388, 567,693, [Group XXIV], and 570,795 are referred to.
Patent GB-950209-A (GB)
Title: Laminated glass assembly
IPC: B32B17/10
Filed: 1961-05-25
Abstract: In the bending of two glass sheets to an identical curvature, which includes at least one compound bend, before bonding to a plastic interlayer, one of the sheets is of glass having a higher heat absorptivity than that of the other sheet.  The glasses disclosed are of the same composition except that the glass of higher heat absorptivity which is used as the upper sheet during bending, contains more iron oxide and is thereby tinted.  The upper sheet upon heating absorbs more heat and therefore softens more quickly so that it will conform more closely to the shape of the lower sheet. The compositions in weight percentages are SiO2 69-74; Na2O 11-15; CaO 9-13; MgO 0.1-5; Al2O3 0.1-1.3; SO3 0.1-0.5; Co3O4 0-0.002; TiO2 trace with for the lower glass Fe2O3 0.01-0.15 and for the upper, tinted, glass Fe2O3 0.3-0.7.

Title: Improvements in or relating to bituminous compositions containing mineral aggregates
IPC: C08L95/00
Filed: 1943-11-15
Abstract: Bituminous compositions are prepared by adding up to 6.5 per cent of water to a mineral aggregate of the kind which becomes at least feebly cemented to a coherent mass when wet, and mixing the product with 3-8 per cent of the weight of the aggregate of a non-dispersed bituminous binder which may or may not wet the aggregate in the presence of water, at a temperature less than 100 DEG  C., the proportion of water in the finished composition being at least 3 per cent of the weight of the aggregate.  Examples of aggregates are natural sand or gravel containing clay or clean sand, gravel or the like to which has been added calcium hydroxide, magnesium oxide, Portland cement, ferric oxide, or clays of the montmorillonite type. Fillers such as china clay, slate dust, precipitated chalk and limestone dust activated by an addition of calcium hydroxide can also be used.  Bituminous binders, which may be cutbacks, may be petroleum asphalts, residual oils, mixtures of asphalts or oils with petroleum or coal-tar distillates, coal tars, pitches, or mixtures thereof with coal-tar distillates, and additives to encourage wetting of the aggregate by the binder may be added.  Preferably from 4 to 6 per cent of water is used, but allowance for evaporation must be made when mixing is carried out at high temperatures.  According to the Provisional Specification, the binder may be added in the form of an aqueous dispersion.

Filed: 1926-07-30
Abstract: 256,949. British Thomson-Houston Co., Ltd., (Assignees of Karapetoff, V.). Aug. 11, 1925, [Convention date]. Systems depending on two or more machines; regulation, automatic.-In order that the terminal voltage of a synchronous machine supplying a power line such as a high-voltage long distance transmission line, may be maintained during transient changes in the load or power factor to which the normal regulating apparatus cannot respond quickly, an auxiliary field winding 4 is supplied from a source which responds substantially simultaneously to the transient changes. A current transformer 12 is connected to the auxiliary field circuit through a dynamo-electric rectifier 7 working in phase synchronism with the synchronous generator 1. The rectifier 7 is preferably a rotary converter bearing an unwound field yoke, which may be an iron ring shrunk over interposed insulators on the armature, and is excited by its armature reaction alone. This machine may be coupled mechanically to the synchronous generator. An inductance 18 and condenser 17 ensure that the voltage of the converter shall operate mainly on sudden increase of load. The variation may be amplified by a thermionic device 13 controlling the auxiliary field current, which is then furnished by an auxiliary source 19. By a switch setting of the brushes of the rectifier the arrangement responds also to changes in factor. According to the Specification as open to inspection under Sect. 91 (3) (a), the field yoke of the rotary converter might have polar projections. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,061,686. Capping bottles. METAL BOX CO. Ltd. Feb. 2, 1966 [May 6, 1965], No. 19208/65. Heading B8T. In a bottle capping machine in which a roller 1 spins the skirt of a cap 22, Fig. 6 (not shown), into the threads around the neck of a bottle &c. 20, Fig. 7, a sensing device 16 in the capping head responds to the absence of a cap upon the bottle to prevent the roller from engaging the threads and damaging them. The capping head comprises a sleeve 11 in which the sensing device 16, fast on a rod 15, is axially slidable. A transverse pin 18 fast in the sensing device 16 is slidable along lengthwise slots 19 in the sleeve 11, and carries at its ends a ring 17 surrounding the sleeve. If the capping head is lowered on to a bottle 20 on which a cap is not in position, the sensing device enters the bottle, as shown, and the ring 17 prevents radially inwards movement of the roller 1. If, however, the capping head is lowered on to the neck of a bottle on which rests a cap 21, Fig. 6 (not shown), the sensing device 16 engages the crown of the cap. As the head continues to descend, the sensing device 16, the rod 15 and the ring 17 are slidden upwardly relatively to the sleeve 11. Accordingly the ring 17 no longer obstructs the inwards movement of the roller 1, which spins the skirt of the cap into the threads. The roller 1 is journalled at the end of an arm 2, and can move axially against the bias of a spring 3 relatively to the arm. The arm 2 is fast on a shaft 4, Fig. 1 (not shown), which can turn a limited amount against the bias of a spring 9 relatively to an actuating arm 5. A cam follower 6 on the actuating arm 5 engages a cam 7, rotation of which turns the shaft 4, the arm 2 &c., to engage the roller 1 with the skirt of the bottle cap.
