Title: Improvements in spindles for driving the rollers of rolling mills
IPC: F16D3/30
Filed: 1931-05-08
Abstract: 370,692. Positive clutches. SCHLOEMANN AKT.-GES., 13, Steinstrasse, Dusseldorf, Germany. May 8, 1931, No. 13643. Convention date, Aug. 13, 1930. [Class 80 (ii).] A spindle a, b for driving the rolls of sheetmetal rolling mills is provided with means for obtaining either a positive drive or a permanently engaged friction drive in order to avoid the necessity for changing spindles when it is desired to change from friction to solid drive between rolls. The friction coupling, which slips under overload, comprises discs c splined to the part a and pressed into engagement with discs d rigid with the part b through a ring k by springs e mounted on screws. The positive clutching element is an axially slidable sleeve f having internal teeth engaging teeth g on the part b. The teeth on the part b have pointed ends and some of them, g, Fig. 4, are longer than others and are axially slidable on the part b so that on initial engagement with the sleeve f they are pressed backwards against the ring k to relieve the pressure on the friction discs and permit the relative rotation necessary for easy engagement of the clutching teeth. The slidable teeth are more sharply pointed than the fixed ones. The part a of the spindle is journalled in the part b as shown, and the sleeve f has internal teeth rigidly engaging coupling members m on the part a in the positive, and members p in the friction driving positions.

Filed: 1943-08-20
Abstract: 632,913. Discharge apparatus. SPERRY GYROSCOPE CO., Inc. Aug. 20, 1943, No. 13644. Convention date, Aug. 3, 1942. [Class 39 (i)] An electric discharge tube comprises resonators 3, 4, and 5, through which an electron stream passes in succession, these resonators having flexible wall portions which may be moved to effect gang tuning by the thermal expansion and contraction of a strut 52 which is provided with adjustable electric heating means. The resonators 3 and 4 are the " buncher " and " catcher " means and the energy is extracted from the third resonator 5 which is only coupled to the others through the electron beam. The coupling may be reduced by inserting a screening grid 35 in the path of the beam between resonators 4 and 5. The tube 19, between resonators 4 and 5, may alternatively be made long to reduce the coupling. In this case an electric field may be maintained between resonators 4 and 5 to accelerate the beam and prevent it becoming debunched before reaching resonator 5. Alternatively, if this field is omitted, tube 19 may be made so long that the beam becomes debunched and then bunched again before reaching resonator 5. The coaxial line terminal 25 comprises a tube 30, silver-soldered to the resonator wall, and a tube 31 spot-welded to tube 30. The inner conductor 29 passes through a glass to metal seal 33. Specifications 632,924 and 632,925 are referred to.

Abstract: 1,58,326. Electrophotographic processes. A.B. DICK CO. April 1, 1965 [April 1, 1964], No. 13891/65. Heading G2H. A persistent internal polarization latent image in a photo-electret is used for repeated development and transfer of the developed image to provide multiple copies. A polarization image may be formed, with depicting radiation from a xeron flash tube, in a layer, containing a zinc, cadmium sulphide phosphor doped with silver, in an organo silicon binder on a paper base, by contact printing in the presence of an electric field. The photo-electret is developed with resin coated pigment particles and the developed image placed in contact with a copy sheet. A D. C. potential, preferably greater than that used for polarization, is applied through electrodes to the opposite faces of the members to effect image transfer. The copy sheet is removed together with its contacting electrode and the image fixed in a conventional way, such as by heating. After repeating the development and transfer processes a number of times the original latent image becomes indistinct and the electret may be depolarized, for re-use, by exposure to actinic or infrared radiation.

Title: Improvements in weighing mechanisms
IPC: G01G1/26
Filed: 1928-05-14
Abstract: 317,356. Hutchinson, G. May 14, 1928. Loose - weight apparatus; weights and weight holders.- In a weighing-scale having supports for holding a loose weight in operative and inoperative position, the weight is provided with sets of supporting surfaces in angular relation to each other to adapt it for a tipping movement from one support to the other. As shown in Fig. 1, the weight 25 comprises a cylindrical body portion mounted on an inverted T-shaped base, that may be integral with the body portion or be formed of sheet metal and firmly secured to the body portion. The weight is carried alternatively by two supports 17, 20 one of which is mounted on the weigh-beam 2 while the other projects upwardly from the base 1. The weight is transferred from one support to the other bv a simple tipping movement effected by the hand of the operator. Each support is provided with a groove 21 to receive the base of the weight, and with a bearing surface 22 to support the body portion. The support 17 is retained in vertical position by a check link 19, and is so proportioned that its centre of gravity and that of the weight it carries are disposed in the vertical plane containing the knife edges 18. The supports' are designed to carry a. plurality of weights of two or more magnitudes, the several weights being maintained in their respective positions by spaced projections in the grooves 21. In order to lessen the shock to the mechanism during transference of a weight, each weight may be provided with a central foot 58, Fig. 9, that cooperates with a bearing 54 formed on each support to reduce the distance the weight drops in any one movement. In a modification, Fig. 10, a number of supports, each for a different magnitude of weight are arranged one above another on a frame 70 that is suspended from the end of a beam 68 and adjacent to a frame 62 carrying a similar number of fixed supports.

Title: Improvements in the manufacture of envelopes
IPC: B31B150/00
Filed: 1958-05-05
Abstract: 893,863. Making envelopes. DOETSCH, W. May 5, 1958 [June 13, 1957], No. 14218/58. Class 94(2). A method of producing envelopes having gummed closure flaps wherein envelope blanks are stacked with the closure flap of each blank relatively staggered by-an amount equal to the width of the edge portion thereof to receive adhesive with the flaps of the blanks on each side, is characterized in that the exposed edge portions of the closure flaps are smoothed and heated by a plate, and adhesive applied to the exposed edge portions, each individual blank being removed and the flaps forming the back of the envelope being folded over and secured together to produce the finished envelope. As shown, envelope blanks 1 are successively separated from a pile by a suction roller 3 and guided towards a belt 5 by air nozzles 4. The blank is fed forward a distance corresponding to the depth of the closure flap to be gummed, on reaching the belt 5 by a roller 11 carried by a rocking lever; after feeding the rollers are lifted until the next blank arrives. Thus, the blanks are fed in staggered relationship between the belt 5 and a belt 14. A heated plate 15 heats and smooths the edge portions of the closing flaps. Adhesive is deposited on the flap edges by a roller 18. Discs 19 and rollers 20 feed the blanks under belts 22, the peripheral speeds of the discs 19 and belts 22 being higher than the belts 5 and 14 in order to reduce the overlap of the blanks. Cold air is supplied through a channel 30 to cool the heated closing flaps and dry the adhesive thereon. A conveyer band 34 co-operating with rollers 35 seize the blanks in turn and due to their speed further reduce their overlap, such that a trailing edge is uncovered. A suction roller 36 grips the closure flap trailing the leading blank and raises this flap such that fingers 39 on rollers 38 convey it to rollers 40, 41. The roller 40 has transverse scoring knives 42, 43 which score the blank to facilitate subsequent folding of the top and bottom closure flaps. Folding blades 48 are spaced apart a distance corresponding to the longitudinal fold lines of the side flaps. Air nozzles 51 raise the side flaps outside the blades 48, these being folded inwards by belts 53 passing around rollers 45, 46, and 47. A roller 58 deposits adhesive on the leading edges of the side flaps. The bottom flap is then folded by a folding roller 54 having suction openings 55 which grip the folded and glued blank behind the bottom fold line, the bottom flap being held raised by air jets 56 until the bottom flap folding line passes into the nip between the roller 54 and a shaft 57. The closure flap is then folded by a buckle folder having plates 64 and rollers 62, 63, and 66. Completed envelopes are delivered between a conveyer belt 71 and disc 72 against stops 74 on a delivery table 75.
