Title: Preparation of acrylic-type polymers which are insolubilized in situ after polymerization and end product application
IPC: C08F20/12
Filed: 1958-10-13
Abstract: A composition comprises (A) a solid polymer derived from a monomer charge consisting essentially of at least one ester of acrylic or methacrylic acid having only one polymerizable group, said polymer being (i) fusible, (ii) soluble in ethylene dichloride at 25 DEG C. and (iii) essentially free of unpolymerized monomer and (B) a photoinsolubilizer, being a chemical compound energizable by ultra-violet light which serves to render the fully polymerized acrylic polymer insoluble in ethylene dichloride at 25 DEG C., said composition being convertible on exposure to ultra-violet light to a condition which is substantially insoluble in ethylene dichloride at 25 DEG C.  Specified photoinsolubilizers are benzaldehyde, p-hydroxybenzaldehyde, anisaldehyde, p-chlorobenzaldehyde, o-chlorobenzaldehyde, p-dimethylaminobenzaldehyde, furfural, acetophenone, p-aminoacetophenone, propiophenone, p-aminopropiophenone, benzophenone, p-hydroxybenzophenone, 4-chlorobenzophenone, desoxybenzoin, benzoin, benzil, xanthone, phenyl benzoate, 2,4-dichlorobenzaldehyde, p-hydroxyvalerophenone and 1,3-indanedione.  The compositions may be prepared by adding the photoinsolubilizer to the monomer and polymerizing the monomer in the presence of a thermal catalyst, dissolving the polymer and photoinsolubilizer in a common solvent and evaporating the solvent, or by treating the polymer, e.g. in the form of shaped articles, with the photoinsolubilizer or a solution thereof.  The compositions may subsequently be insolubilized by irradiation with ultra-violet light. Insoluble graft polymers may be prepared by placing styrene in contact with the composition and irradiating, when graft polymerization and insolubilization occur. Examples describe the thermal polymerization in the presence of acetyl peroxide and insolubilization of (1) methyl methacrylate containing various photoinsolubilizers; (2) methyl methacrylate, (4) cetyl-stearyl acrylate and methacrylate, octyl acrylate, and mixtures of octyl and decyl methacrylates containing o-chlorobenzaldehyde; (3) the insolubilization of polymethyl methacrylate containing o-chlorobenzaldehyde; (5) the insolubilization in vacuum of polymethyl methacrylate containing o-chlorobenzaldehyde; (6) the emulsion polymerization and insolubilization of methyl methacrylate containing o-chlorobenzaldehyde; (7) the insolubilization of a coating resin comprising an ethyl acrylate-methyl methacrylate copolymer and o-chlorobenzaldehyde dissolved in toluene; (8) the insolubilization of ethyl acrylate-methyl methyl methacrylate copolymer fibres dipped in o-chlorobenzaldehyde; (9) the insolubilization of polymethyl methacrylate containing benzoin by p sunlight; and (11) the formation of an insoluble graft styrene-polymethyl methacrylate product.  The products may be used for the manufacture of films, fibres, rods, tubes, coating compositions and ion exchange resins, and the formation of designs by exposure through a stencil.  Specification 574,692 is referred to.

Title: Apparatus for optical sound recording and reproducing
IPC: G11B7/00
Filed: 1933-11-23
Abstract: 417,741. Optical sound recording and reproducing apparatus. SELENOPHON LICHTUND TONBILDGES., 25, Neubaugasse, Vienna. Nov. 23, 1933, No. 32762. Convention date, Nov. 26, 1932. [Class 40 (ii).] Apparatus for recording sound on an opaque carrier, and for reproducing the sound by means of reflected light, is characterized by the provision of two optical systems, so arranged with their axes in one plane that the same apparatus may be used either for recording or for reproducing. One of the optical systems may also be used for monitoring during recording. As shown, light from a source L is condensed by lenses K, and passes through a slot B, an image of which is focused by a lens system A on a vibratory strip K<1> forming part of a light valve. A lens system C projects an image of the edge of the illuminated member K<1> on a point P on an opaque strip T of paper or the like, so that the sound is there recorded. A second optical system D focuses light reflected from the record strip, on to a photoelectric cell Z, whereby reproduction from a previously made record may be effected with the same apparatus, the member K<1> in this case being stationary. The optical system D may be used for inspecting the image at the point P during recording, by reflecting a part of the beam through a prism Q on to a frosted screen N, whilst the cell Z may at the same time provide a means for monitoring acoustically. The record strip is driven by a roller R of large diameter, which moves the strip by friction due to adhesion.

Title: Electric time switch
IPC: H03K17/288
Filed: 1966-07-21
Abstract: 1,148,736. Timing circuits. WERNER ZINDLER [trading as LUMOPRINT ZINDLER, K.G. July 21, 1966 [July 21, 1965], No.32882/66. Heading G3T. [Also in Division H1] An electric time switch for controlling an electrically operated device 5 comprises a relay 21 operating in conjunction with a manual trigger 25 which in its operated position permits, by disengagement of a stop 29, a repetition of time intervals for controlling the activated period of the device, the stop moving back to its initial position at the end of the time interval during which the trigger is released to disconnect the device. An armature 32 of the relay 21 controls the contacts of an on-off switch 6 and a change over switch 15 so that normally the stop 29 holds the armature against the core 34 of the de-energized relay, thus keeping the switch 6 in an off position and contacts 17, 18 of the switch 15 in engagement. On depressing the trigger 25, the armature pivots anti-clockwise and abuts the stop 29 thereby holding the trigger depressed and connecting resistors 12, 13 to a source of power 1 through the switch 6. At the same time, contact is made between the terminals 16, 18 of the switch 15 and a condenser 22 charges up until its potential reaches the firing potential of a relay valve 9 whereupon the condenser discharges and a current flows through the relay 21. The armature 32 is thus attracted to the core 34 causing the switch 6 to disconnect the device 5 from the source 1 and a spring 30 urges the trigger 25 upwards into its initial position since the armature no longer abuts the stop 29. The period for which the device 5 is switched on may be varied by adjusting the variable resistance 13 and if the trigger is held depressed the timing interval is repeated until the last interval during which the trigger is released has been completed. The switching of the relay may be made available by a chopper co-operating with the armature and stricking a plate.

Title: Improvements in and relating to a method in the tanning of the hides of large whales
IPC: C14C13/00
Filed: 1947-12-16
Abstract: 656,848. Leather from whale hides. BEN. DIXEN, K. Dec. 16, 1947, No. 33154. Convention date, Nov. 19, 1938. [Class 76] Tanned hides of large whales, especially true whales, black whales, and finback whales e.g. the common finback whale or the blue whale, are prepared from hides including the fat-yielding tissues, so-called blubber, which contains leather-forming fibres, by removing the epidermis and, before or after tanning, subjecting the hide to a compression at right angles to the surface at a moderate temperature preferably a temperature not exceeding 30‹ C., whereby the fatty substance or part thereof is pressed out without detrimentally influencing the hide fibres and the glue tissue, thus forming a raw hide or leather, the raw hide being afterwards converted into leather by tanning. The epidermis is removed by scraping the moist hide, which may have been preserved in salt. If the hide so scraped is then salted, the salt is removed before tanning. If desired, the tanned leather may be treated with a solvent, e.g. petrol to remove contingently remaining fatty substances. For chamois leather, compression is carried out during the fulling process.

Filed: 1922-12-05
Abstract: 216,805. Burn, J. F., Lancaster, J. S., and Langford, H. Dec. 5,1922. Coating-machines.-In a process for coating or impregnating stone or other material with tar or other liquor, the dried stone &c. is charged in equal quantities into perforated buckets 28 pivotally mounted on an endless chain 29, the motion of which is interrupted at regular short intervals to facilitate charging, the full buckets being passed through the liquor tank 33. As the buckets rise from the tank, the superfluous liquor drains back to the tank, and later the buckets are tipped to discharge the coated material. In the tar-macadam plant shown, the buckets are driven from a power shaft 9 through a gear-box 35 which receives a continuous drive and gives out an intermittent drive. The stone, after leaving the drying drum 1, is raised to a hopper 4 the base of which is fitted with a revolving tray 10 and a fixed vane 11 for delivering the stone through an aperture in the rim of the tray into a fixed measure 12. During the period of rest of the buckets 28, a feed-box 15 is reciprocated between the measure 12 and the buckets 28 by the cam gear 22. The arrangement is such that discharge doors 13 on the measure 12 are automatically opened when the box 15 moves below the measure 12, and similar discharge doors 18 on the box 15 is automatically open when the box is over a bucket 28. The buckets are tipped by the engagement of cams 42 thereon with a fixed inclined rail 43.

Abstract: 678,389. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd. Dec. 29, 1950 [Dec. 30, 1949], No. 33329/49. Class 40 (vii). In a frequency-modulated radio altimeter system, comprising a frequency-modulated transmitter 1 coupled to a transmitting aerial 2 and a receiver 4 coupled to a receiving aerial 5, the couplings in each case comprising a delay line and an attenuator, for the purpose of reducing the effects of beat-frequency signals having frequencies close to that of the desired signal and occurring as the result of the reception of echo signals over more than one path. As shown in the Figure, echo signals may be received as the result of either one or two reflections from the ground 11. The beat-note occurring between these two signals has a frequency close to that which the desired beat note would have in a conventional radio altimeter; however, by virtue of the delay networks 12 and 14 the frequency of the desired beat note is increased above that of the spurious which accordingly may be suppressed by the high-pass filter 4a at the output of the receiver. The output from filter 4a is then applied to a frequency measuring circuit 7 and thence to an indicator 8. In addition spurious signals may result from echo signals received by transmitting aerial 2 and applied thence to the receiving circuits or from signals generated by transmitter 1 and transmitted from receiving aerial 5. The effects of such signals are reduced by attenuators 13 and 15 which are coupled to the indicator 8 so that they are introduced gradually into the circuit as the altitude decreases below a predetermined value In a modification, Fig. 2, the transmitting aerial. 19 is connected to the output 20 from the transmitter by wave-guide 21 and delay line 22. The receiving aerial 25 is coupled through delay line 26 and wave-guide elements 24 and 27 to crystal mixer 28 to which the transmitter is also coupled through the directional wave-guide coupling 23. The mixer output is applied to a frequency-measuring circuit 30. Two mechanically coupled attenuators 31, 32 are arranged in the wave-guides 21, 24 as shown. In this arrangement the directional coupler prevents energy from being radiated from aerial 25 and prevents that received on aerial 19 from being applied to the crystal mixer 28. A further arrangement involving the use of a " Magic-T " wave-guide hybrid coupling unit is illustrated in Fig. 3 (not shown). In this signals from the transmitter and from the receiving aerial are applied to respective conjugate arms of the " Magic-T ", the other arms being connected to respective crystal mixers, the outputs from which are fed in balanced fashion to the frequency measuring circuit.
