Title: Improvements in electro-acoustic signalling devices
IPC: G10K9/18
Filed: 1935-11-13
Abstract: 470,489. Diaphragm vibrators. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 13, 1935, No. 31434. Void. Convention date, Dec. 17, 1934. [Class 13] [Also in Group XXXIX] In a signalling system an electricallyactuated driving unit 1 having a marked resonant frequency and permanently connected at 2 to an electrical supply network chiefly used for other purposes, is arranged relative to a diaphragm 4 so that the latter produces a signal only when current of a frequency approximating to the resonant frequency is imposed on the network. The amplitude of vibration of a pin 3, forming the actuating member of the unit 1, in response to the current normally supplied, e.g. 50 cycles, is insufficient to effect contact with the diaphragm 4, the flat end 7 of which is actuated in response to current of the resonant frequency, e.g. 500 cycles. The diaphragm, which preferably has a resonant frequency below that of the driving unit, may be supported at its rim 5 by a ring of textile fabric or by small springs 6 and may be stamped from light metal or may be formed of paper with the flat end 7 reinforced by a metal cover plate.

Abstract: 795,976. Electric selective signalling systems. COLLINS RADIO CO. Nov. 7, 1955 [April 6, 1955], No. 31772/55. Class 40 (1). Apparatus for positioning a shaft 10 in any one of a number of predetermined angular settings comprises groups A and B of single pole switches actuated by levers 11. The shaft 10 is driven by a motor 14 and is coupled to a rotor 12 having a periphery of conducting material, and two notches e, f, co-operating with contacts 40 to 44, and a rotor 13 co-operating with contacts 47, 48, contact 47 being earthed. A notched stop-wheel 18 locks the shaft 10 in any of ten positions and is released when relay 23 actuates pawl 19. The levers 11 of the control switches are normally to the left and are operated by a pin-drum 69, Fig. 4, which has ten rows of pins, each row having two pins 71, 72, pin 71 operating any switch in group A according to its position along the slot 73 and pin 72 either actuating or not actuating the switch in group B depending upon which of its two positions along slot 74 are selected. The pins 71, 72 are locked in the desired positions by detent means (not shown). As shown, the apparatus is set for position 4 and with the notch e of rotor 12 at contact 44 the motor 14 is de-energized. If, for example, the pin-drum is set to position 3 the circuit is completed and the rotors rotate until notch f of rotor 12 is opposite contact 43 and opens the circuit through wire 53. In this position a circuit is completed through rotor 13 and contact 48 until notch e of rotor 12 aligns with contact 43 again to open the circuit and stop the motor. Other positions of output shaft 10 are similarly obtained. In a modification, Fig. 2 (not shown), using three groups of switches and three rotors, eighteen positions of the output shaft out of a possible twenty are provided, the remaining two positions being excluded by an electrical interlock. In a further arrangement, Fig. 3 (not shown), two output shafts are operated by a single pin-drum to give pre-selected positions and at each position different combinations of crystals are selected to change the frequency of an oscillator circuit. In addition, a changeover switch is provided, whereby the pin-drum control may be dispensed with and a further manual switching control, giving a wider choice of frequencies but requiring the setting of a pair of dials, brought into use. Specification 660,939 is referred to.

Title: Method for forming sheet metal blanks
IPC: B21D22/10
Filed: 1956-10-22
Abstract: 830,783. Stamping. SVENSKA AEROPLAN A.B. Oct. 22, 1956 [Oct. 25, 1955], No. 32060/56. Class 83 (4). A method for forming metal sheet blanks, e.g. annular aircraft frames, is characterized in that the forming is made in at least two steps such that the sheet metal part by bending along a curved form error producing bending line is given a suitable form error in the preforming and is then repressed to its final form along a bending line displaced from the said form-error producing bending line so that the sheet metal part will receive in the final forming tensile and compressive stresses of a reversed direction to the tensile and compressive stresses occurring in the material at the preforming. The contour error is approximately the thickness of the sheet. The blankis placed on a forming block 4 provided with a forming die 2 and a wrinkle preventing support wall 3. A rubber pad 5 produces flanges 6 and 7 on the sheet bent along a contour-error bending line. This preforming produces compressive and tensile stresses on the sheet which cause spring-back as shown in Fig. 7. The preformed sheet is heat treated and then placed on the final forming block 10 and repressed to its final form whereupon the compressive and tensile stresses produced at the preforming are reversed.

Abstract: 335,410. Clorius, O. T. Oct. 22, 1928, [Convention date]. Addition to 249,423. Thermometers.-In apparatus as described in the parent Specification in which the mean temperature of a. room &c. over an extended period is estimated by the evaporation of a liquid from a container, the container consists of a narrow glass tube of about 4 to 5 mm. bore mounted in a frame and the nature of the liquid is such that the rate of evaporation is approximately inversely proportional to the depth of the liquid surface in the tube. The tube a partly filled with liquid is mounted in the frame b provided with a scale f the spacing of the graduations on which decreases downwardly on account of the decreasing rate of evaporation. The tube can be adjusted vertically by a screw c to bring the liquid level initially to the zero of the scale. A projection g prevents the tube from being moved too far upwardly. The frame b forms a hood over the mouth of the tube to prevent unauthorized filling of the latter. To obtain a reading indicating the heat consumption in a room &c. the number of divisions on the scale is varied according to the size of the room. For example, if the instrument shown is suitable for a room of a particular size, then for a room of twice the volume the same length of scale would be graduated from 0 to 60.

Title: Manufacture of benzaldehydes containing trifluoromethyl groups
IPC: C07C45/43
Filed: 1935-11-20
Abstract: Trifluoromethyl benzaldehydes are made by treating trifluoromethyl benzalfluorides with concentrated sulphuric acid at a raised temperature.  The products are easily oxidized to the corresponding benzoic acids, combine with bisulphite, and give the corresponding acid chlorides with chlorine.  They are intermediates for dyestuffs, pharmaceutical products and fungicides or insecticides.  In examples: (1) o- (or m- or p-) trifluoromethyl-benzaldehyde is obtained from o- (or m- or p-) trifluoromethyl-benzalfluoride; (2) the corresponding nuclearly substituted xylene pentafluorides, such as the mono- or di-halogen derivatives, give the corresponding trifluoromethyl-benzaldehydes, such as 4-chloro-1-trifluoromethyl-2-benzaldehyde; (3) the octachlorination product of pseudocumene is converted to the corresponding octafluoro compound, and the latter, or mesitylene octafluoride or a nuclear substitution product of either is treated with sulphuric acid. Trifluoromethyl - benzalfluorides are obtained from polymethylbenzenes by chlorination according to Specification 114,645, [Class 2 (iii)], or 465,885 to produce a trichloromethyl-benzalchloride, followed by exchanging the chlorine atoms for fluorine according to any known process such as that described in Specification 395,227.
