Title: Improvements in or relating to glass-working processes and furnaces
IPC: C03B5/06
Filed: 1933-02-23
Abstract: 405,806. Glass furnaces. FECHOZ, E., Gilly-sur-Isere, Savoie, France. Feb. 23, 1933, No. 5617. Convention date, Feb. 23, 1932. [Class 51 (ii).] Relates to glass-melting furnaces and comprises arrangements by which a stream of glass is exposed at a number of gathering points, and is reheated to melt the cuttings between these points. In the circular pot furnace shown in Figs. 1 and 2 the glass from one or more pots 2 overflows into a channel 8 connected at one end 9 to a concentric outer channel 10, in which the stream is exposed at a series of gathering points 11, 12. Between these points the channel is enclosed and the glass therein is subjected to the heat of the furnace. Each melting-pot is formed with a perforated false bottom 4 and a passage 5 leading to the spout 6. In the tank furnace shown in Fig. 4 the flow of glass along the channel 15 is promoted by a worm 17 which returns surplus glass to the tank. A similar device mav be used in the pot furnace between the channels 10, 8. The gathering-well is made as shown in Fig. 5 with a slot 18 at its extreme outer part, through which the glass enters the well from below.

Title: Ferromagnetic ferrite materials for use at microwave frequencies
IPC: C04B35/26
Filed: 1963-02-15
Abstract: 981,143. Magnetic compositions. STANDARD TELEPHONES & CABLES Ltd. Feb. 15, 1963 [Feb. 22, 1962; Jan. 23, 1963], No. 6263/63. Heading H1H. A ferromagnetic ferrite material of spinel crystal structure and suitable for microwave devices requiring stable thermal properties has the formula where x+y= 100 and 0.5 # y # 90, and L and Q represent one or more of the bivalent metals Fe<SP>**</SP>, Mn<SP>**</SP>, Co<SP>**</SP>, Ni<SP>**</SP>, Mg<SP>**</SP>, Zn<SP>**</SP>, R represents one or more of the trivalent metals Fe<SP>***</SP>, Cr<SP>***</SP>, Al<SP>***</SP>, Ga<SP>***</SP>, Mn<SP>***</SP>, Ti is quadrivalent titanium, and Fe 2 O comprises at least ¥ of the R 2 O 3 . Essentially the material is a solid solution of the two components (LOR 2 O 3 ) and (TiO 2 2QO), both of which have similar spinel crystal structures, and is preferably made by sintering a mixture of these two components in powdered form. The two components may each have undergone a presintering in air at 1000‹ C. for an hour prior to the main sintering. The main sintering, which is carried out after the powder mixture has been pressed into shape, comprises a slow rise in temperature to 800‹ C. over several hours, 4 to 5 hours at 1200‹ C. and slow cooling over 20 hours, all in O 2 . The alternative process of sintering from the constituent metal oxides is also envisaged. Specific examples disclosed are 70(NiOFe 2 O 3 ) + 30(TiO 2 2ZnO), 90(NiOFe 2 O 3 ) + 10(TiO 2 2MgO), 90(0.92MgO, 0.18- MnO, 0.90Fe 2 O 2 ) + 10(T 1 O 2 . 2ZnO). The material may be used in a Faraday rotator and in a phase-shifter where a constant phase-shift over the temperature range 0-120‹ C. may be obtained.

IPC: A61M5/315
Filed: 1964-02-14
Abstract: 990,808. Blood collecting assembly. BECKTON DICKINSON & CO. Feb. 14, 1964, No. 6334/64. Heading A5R. [Also in Division F1] A blood or other liquid collecting assembly comprises a tubular container 11 having a pierceable self - sealing stopper 14 for maintaining a vacuum in the container 11 and a holder for the container 11. The holder may comprise end plates 16 and 18 joined by strips 17 which strips converge towards each other, and have grooves 22 and abutments 23 (Fig. 1). In Fig. 8 the holder comprises a tubular body 25 having abutments 27. The holder has at one end an opening through which the container 11 can be slid longitudinally, open end first with the stopper 14 in place, and at the other end a cannula 20, the holder being provided with an abutment 23 or 27 which when the container is slid into the holder in one angular position, engages an extension 12 on the stopper 14 and arrests the movement of the container 11 in a position in which the cannula 20 penetrates into but not through the stopper 14, but which when the container 11 is rotated to a new position no longer engages the extension 12 so that the container 11 can be slid further into the holder to a position in which the cannula 20 extends right through the stopper 14 into the interior of the container 11. In collecting blood, the container is slid into the holder until it is held in its arrested position, the cannula is inserted into the vein, and then the container is rotated and slid further into the holder such that the blood is withdrawn from the vein through the cannula into the container.

Title: Improvements relating to means for zeroising the indicating mechanism of liquid measuring and dispensing apparatus
IPC: G01F15/07
Filed: 1936-03-03
Abstract: 471,486. Dispensing measured quantities of liquid ; zeroizing mechanism. AVFRY-HARDOLL, Ltd., and FRASER, J. March 3, 1936, No. 6381. [Class 116] [Also in Group XIX] Liquid measuring and dispensing apparatus of electrically driven flow-meter type has means for zeroizing the indicators immediately prior to the delivery of a fresh quantity of liquid comprising an hydraulic motor having mechanically-operated valve-mechanism associated with the main control-switch of the apparatus. A vane 14 in a casing 11 drives a shaft 13 having an arm 15 carrying a pawl 16 drives a ratchet wheel 17 secured to a wheel 18 geared to the wheels 21, 22, 20 driving the priceindicating drums, the wheel 18 also driving a ratchet wheel 26 by a pawl 25 to zeroize the quantity indicators. The vane 14 is moved by fluid-pressure generated in the dispensing line when the nozzle is removed from a hook on the lever 9, such removal of the nozzle causing the lever 8 to swing to close the pump motor switch 6 and to raise a rod 35 coupled through a lever 34 and arm 32 to a pawl 31 which rocks a twoway valve 10 by means of a bar 10b to place the pipe line in communication with the space behind the vane 14. The pawl 16 is held disengaged by a pin 16a during the initial movement of the vane. At the end of the zeroizing movement, the vane trips the pawl 31 which allows the bar 10b to turn the valve 10 under the influence of a spring thereby admitting liquid on the opposite side of the vane to return the vane to initial position, and relieving the pressure on the non-working face of the vane. The quantity and price indicators are arrested at the zero position by stops, frictional drives being provided to allow the vane to move a distance greater than that necessary for zeroizing. Specification 465,347, [Group XIX], is referred to.

The bottom 21 of the frame is bowed upwards when free but, in fixing, a press 35 flattens this plate out and simultaneously side welding electrodes 37, 38 force the arms 22, 23 against the edges of plate 26 and weld them in position. The assembly may be inserted in a casing with a liquefiable filling, or mouldable material may be formed round it. In a modification for high voltages a cylindrical ceramic block 56, Fig. 14, has a rectangular opening to accommodate the stack 64 and filling compound 63. Ends 57, 58 are attached by screws. In this instance the side arms 65, 66 of the threesided clamping member, are made in separated parts held together so as to resist tension by a moulded insulation wrapping.
