Abstract: 906,697. Gloves. GERARD, J. C. Nov. 19, 1958 [June 2, 1958], No. 37301/58. Class 141. [Also in Group VIII] A disposable medical examining glove is formed from synthetic plastic sheet material by disposing a double web of the material on a web of paper and stamping the double web with a heated die shaped to the outline of the desired glove, the die being at a temperature sufficient to cut the plastic webs into the shape of the die and to seal the opposing edges of the cut plastic outline but to avoid charring of the paper web. As shown, webs of plastic material 4 and 6 together with a web of paper 8 are fed from feeding station 10 to stamping station 12 where the cutting and sealing assembly 38 descends on the composite web supported on backing-plate 36 and cuts and seals the edges of the plastic webs in the desired form. The web then passes to lubricating station 14 where a lubricating material such as talcum powder is blown into the formed glove and then past a cutting-knife 48 for trimming off the edges thus leaving separated gloves resting on the paper web. The gloves &c. then pass to a waste removal station 16, consisting of a hopper 54 for receiving the waste plastic material and a hopper 56 for receiving the waste paper strip, and then to a web cutting station 18 where a transverse knife 57 cuts the paper web so that each glove with a paper backing falls into hopper 60. The webs are fed intermittently and dancers 72 and 78 are provided to take up the slack in the webs. The feed is so arranged that when one glove is being stamped another is at the lubricating station and another is being cut off by knife 57.

Title: Tempered glass
IPC: C03B27/03
Filed: 1963-09-24
Abstract: A thermally tempered glass article which has a surface compressive zone, an intermediate compressive stress and an interior tensile stress zone, the maximum compressive stress of said surface zone being greater than both the maximum stress of said intermediate zone and said interior zone contains at least two alkali metals of different atomic diameters, there being a greater concentration of the alkali metal of greater atomic diameter in said surface compressive stress zone than in said intermediate compressive stress zone and said interior tensile stress zone.  The greater concentration of the larger atomic diameter alkali metal is preferably in a portion adjacent the outer surface of the article; that is, up to a depth of about 10 microns.  The glass is usually of the soda-lime-silica type and the larger potassium ion is substituted for the smaller sodium ion.  A glass article of the above type has a surface-compressive stress of at least 40,000 pounds per square inch. A method of treating a glass to form the above article comprises thermally tempering the glass in any known manner, cooling the tempered glass to ambient temperatures, thereafter preferably preheating the glass at least to the fusion point of the alkali metal salt of larger atomic diameter to be used and contacting the glass for a given period of time with the salt, e.g. from 5 minutes to 48 hours, at a temperature below the strain point of the glass. The glass article is then cooled.  A soda-lime-silica plate or sheet glass is usually treated with potassium nitrate either molten or solid, at temperatures from 750 DEG  F. to the strain point of the glass, and may have been preheated to a temperature of 950 DEG  F. The glasses may have compositions in the ranges of over 40% Si; 0-15% B2O3, 0-35% Al2O3; 0-25% CaO, MgO, SrO, BaO, PbO and/or ZO, 0-10% TiO2, 0-10% K2O, and 2-20% Na2O and/or Li2O.

Abstract: 1,065,962. Telephone diallers. C. GNECCHI and G. SOMMARUGA, [trading as ING. C. GNECCHI & C. SOC.]. Oct. 1, 1963 [Oct. 5, 1962], No. 38639/63. Heading G5R. [Also in Division H4] A repertory dialler comprises a magnetic tape movable past a recording/reproducing head adjustable to read from or write on to one of a number of tracks corresponding to wanted subscribers' numbers, and switch means capable of either connecting a subscriber's telephone dial for recording numbers on the tape, or for reading out recorded impulses to line, or for dissociating the repertory dialler from a connection. As shown, Fig. 3, a continuous magnetic tape 9 is driven, by a motor 14 via gears 15, 16 and shaft 12, between a pressure pad 23 and a recording/reproducing head (not shown) mounted on a block 19. The latter is movable transversely, by a wire 22 operated by the knob 27, to select the required track on the tape. The identities of the subscribers are inscribed on labels positioned in recesses 5<SP>1</SP> on a drum rotated by the knob 27, and the selected identity appears through a window in the casing (not shown). A selector switch (not shown) is located on the other side of the drum for selecting the recording, reproducing &c. functions. A push-button start switch 8 is provided. Circuit components are mounted on jacked-in printed circuit panels 34, 35. A switch located at 33 cooperates with a slot 9a in the tape to mark the end (and beginning) of the track. Circuitry.-As shown the tape motor is started by push-button 8, a secondary winding 14<SP>11</SP> providing low-voltage current which after rectification provides D.C. for the transistor circuits, and also operates 54 which keeps the motor running until its circuit is opened by switch 33 at the end of the track. In position 7b of the selection switch the telephone circuit T 1 , T 2  is connected directly to the exchange line L 1 , L 2  and the dialler is disconnected. In position 7c relay 46 is energized over the telephone loop and transistors 47a, 47b are connected as an oscillator, the arrangement being that when 46 closes contact 46a, D.C. is passed through the recorder/reproducer head, to magnetize the tape, to obliterate any signals thereon, but when 46a opens due to an impulse the oscillations from the oscillator are recorded. During this time a bell 48 is connected across the line to receive any incoming calls. In position 7a transistors 47a, 47b act as A.C. amplifiers for the oscillations picked up from the tape, the output being rectified at 55 and applied to D.C. amplifiers 47c, 47d whose outputs operate a slow release relay 49 and an impulsing relay 50. Relay 49 short circuits the line L 1 , L 2  to prevent clicks in the telephone earpiece and relay 50 repeats the impulses to line.

Abstract: 960,629. Winding material on to spools. SIEMENS-SCHUCKERTWERKE A. G. Nov. 3,1961 [Nov 4, 1960], No.39516/61. Heading D1J. An apparatus for the continuous winding of wire or like filamentary material comprises a turntable 3, Figs. 1 and 2, having first and second main spools 10, 10<SP>1</SP> thereon, each main spool having a coaxially arranged auxiliary spool 11, 11<SP>1</SP>, and means whereby when the main spool 10<SP>1</SP> is uppermost and is nearly full the turntable 3 is indexed to move the spool 10<SP>1</SP> down to the lower setting shown and to bring the empty spool 10 and its associated auxiliary spool 11 up to the winding position, the auxiliary spool 11 then acting as a pulley for the material being fed to the main spool 10<SP>1</SP> until the main spool 10<SP>1</SP> is full. When the main spool 10<SP>1</SP> is full the auxiliary spool 11 is caused to grip the material and sever it from the fully would spool 10<SP>1</SP>. After a predetermined length of the material has been wound on to the auxiliary spool 11 the material is automatically transferred to the main spool 10. The material on the auxiliary spool is used as a tail leading to the winding on its associated main spool. Gripping and severing means. Each auxiliary spool comprises a detachable winding cone 13<SP>1</SP>, Fig. 4, that co-operates with a conical attachment 12<SP>1</SP> to form a pulley over which the filamentary material 19 may pass. When the auxiliary spool is required to grip and wind up some of the yarn 19, the cone part 13<SP>1</SP> is moved away from the conical attachment 12<SP>1</SP> so that the yarn is pulled into a gripping groove 33<SP>1</SP> and, as the groove is rotated with the auxiliary pulley in the direction of the arrow in Fig. 5, that portion of the yarn extending between the groove 33<SP>1</SP> and the filled spool 10<SP>1</SP> is quickly-drawn against a blade 35<SP>1</SP> to sever the filamentary material leading to the filled spool. Traversing member. The filamentary material is fed on to the auxiliary and main pulleys by a traversing member sliding on a guide shaft. Whilst the initial turns are being wound on an auxiliary spool, stops limit the travel of the traversing member but as soon as the desired number of turns have been wound on the auxiliary spool one of the stops is swung away to permit the traversing member to oscillate along the length of the main spool.
