Title: Improvements in pressure sensitive adhesives and adhesive tapes
IPC: C09J7/21
Filed: 1954-11-03
Abstract: A pressure sensitive adhesive is prepared by blending an aqueous latex with a solution of a thermosoftening resinous tackifier in a volatile solvent that is a swelling agent for the rubber, to form a blend containing 30 to 200 parts by weight of tackifier per 100 parts by weight of rubber and an amount of volatile solvent greatly in excess of the amount of water, and converting the blend to a smooth continuous viscous rubbery liquid in which the water is dispersed in a continuous phase.  In one example 167 parts by weight of concentrated Hevea latex (60 per cent rubber) are added with agitation to a solution of 100 parts terpene resin tackifier in 1010 parts heptane.  A solution of 2 parts alkylated polyhydroxy phenol antioxidant in 100 parts ethyl-isobutyl, or isopropyl alcohol is then added with continued agitation.  Gum, wood, or limed rosin, an ester gum such as glycerol or pentacrythritol abietate or hydrogenated indene polymers may be used in place of the terpene resin tackifier. In a further example the solution of tackifier resin contains as a plasticizer, lanolin and/or tricresyl phosphate, dioctyl phthalate, or mineral oil, and the latex contains kaolin or other filler, e.g., hydrated alumina, hydrous aluminium silicate, or zinc oxide.  Carton sealing adhesive tape may be prepared by applying the pressure sensitive adhesive composition to one side of a fibrous sheet, the fibres of which have been lightly coated with polychloroprene, the other side of the sheet being coated with a non-adhesive coating, e.g., as described in Specifications 645,057 and 683,927 [both in Group VIII].

Title: Arrangement for keeping constant the frequency of a vibrating  crystal
IPC: H03H9/08
Filed: 1974-07-18
Abstract: 1435665 Automatic control of temperature ITT INDUSTRIES Inc 18 July 1974 [24 July 1973] 31851/74 Heading G3R [Also in Division H1] To stabilize the temperature of a crystal vibrator, a semi-conductor device in direct contact with the vibrator produces heat when too cold or alternatively absorbs heat when too warm. The device, carrying a vibrator such as a crystal tuning fork Fig. 1 (not shown) hermetically sealed under a cover on a preferably thermally insulated base may comprise a transistor or diode as heater or a Peltier cooler. For compactness the device and its controller, optionally together with the oscillator circuit, may comprise an integrated circuit chip. On chip 11 heater transistor 12 and control transistor 13 share a common collector substrate carrying separate base areas themselves carrying separate emitters; 12 is a heavy current transistor designed for avalanche breakdown to a high collector current condition when its emitter a base voltage is sufficiently highly reverse biased. Control transistor 13 diode-connected forms a bridge with resistors 16, 17, 18 and passes current increasing with temperature; at low temperature the drop across resistor 16 is therefore less than that across resistor 18 in the constant bridge arm 17-18, causing differential amplifier 15 to reverse bias transistor 12 sufficiently for avalanche; the subsequent rise in temperature reduces the bias, switching off the avalanche. To cool the vibrator the transistor 12 may be replaced by a Peltier element in series with a device providing a current increasing with temperature, e.g. a diode. Heating and cooling devices may be combined, each operating in its own range on either side of target temperature.

Filed: 1920-11-22
Abstract: 175,099. Pochin, F. H., and Pochin, H. S. Nov. 22, 1920. Stamping; stopping and starting arrangements. -Relates to power-driven machines for stamping marks on boot soles &c., and comprises a parallel-link arrangement for supporting the revoluble die-carriers, and an improved tripping- device for starting and stopping the machine. As shown in Fig. 1, the support 4 for one or more die-carriers 5 is mounted on parallel links 3 and is suspended on the bolt 90 carried by a crosshead 9 which is mounted on rocking links 10, a strong adjustable spring 12 being disposed between the cross-head and support. The arrangement enables the support to yield slightly during impression, and permits adjustment of the support without canting the faces of the dies 6. The work is placed on a table 7, which is raised by a lever 13 operated by a cam 16 on the driving- shaft 18 and a spring 15, a hit-and-miss device, controlled by the work, being arranged between the lever and the guide-stem 8 of the table. The device consists of a pin 21 formed on a block 23, which is pivoted in the stem, a spring 25 normally holding the pin in register with a recess 22 in the lever. The block is connected to a slide 20 which is mounted in a rocking support 19 and carries a trip 33 engaging a lever 29 coupled to a slide 26, which is pushed backwards by the work, the pin 21 being thereupon engaged by the lever and the table being raised. In rising, the table rocks the slide 20 and releases the trip from the lever, the spring 25 thereupon rocking the pin 21 to prevent repeated impression. On withdrawal of the work, a spring 32 returns the slide 26, and the lever 29 re-engages the trip. The trip can slide on a part 33a having a pin 34 entering a slot in the block 35. A spring 36 projects the trip when released, and a blade spring 44 permits the trip to yield when re-engaging the lever 29. The slide 26 is adjustably connected to the lever 29 by a catch 31. To prevent accidental operation of the machine, the front end of the lever 1 3 can be raised by a cam 38, the roller 14 on the lever being thereby depressed below the cam 16, and the table being raised to the highest position. According to the Provisional Specification, the slide 20 interposes a member between the table and the lever 13.

Title: Improvements in electrical apparatus utilizing a dielectric medium
IPC: C02F1/46
Filed: 1964-08-12
Abstract: <PICT:1080624/C6-C7/1> Electrical apparatus e.g. a Kerr cell or high-capacitance condenser, comprises an electrically insulating enclosure 1, Fig. 1 divided into three compartments 2, 3 and 4 by two semi-permeable diaphragms or permeability-selective membranes 8 and 9 with large-area plate electrodes 5 and 6 arranged in the side compartment 3 and 4, the three compartments being filled with an organic polar liquid e.g. nitrobenzene, nitrotoluene, acetone or acetonitile, such that when a potential difference is applied between the electrodes an electro-dialysis action takes place causing purification of the polar liquid in the central compartment 2 i.e. producing a polar liquid having high resistivity and dielectric characteristics. In Fig. 1 selective membrane 8 is of the anodic type i.e. passes negative ions, and selective membrane 9 is of the cathodic type. The polar liquid introduced into the side compartments may differ from the liquid in the central compartment although preferably they are initially filled with the same liquid.  The low natural ionisation present in the liquid in the central compartment is sufficient to initiate an electrodialysis action when a high potential is applied thus decreasing its ion concentration and increasing its resistivity. The Specification states that optimum operating conditions i.e. with the full voltage across the electrodes creating an intense electric field through the liquid dielectric in the centrsl compartment, may be retained for practically indefinite periods of time without it being necessary to renew or regenerate the liquid in the central or side compartments.  Agitation at intermediate periods may be imparted to the liquid in the side compartments to preclude the possible creation of concentration gradients. The liquid in the central compartment may be circulated slowly for temperature control.
