Title: Manufacture of ceramic foams
IPC: B01D39/20
Filed: 1978-02-22
Abstract: Ceramic foams having a permeability, measured as air permeability of 100 x 10<-7> cm<2> to 10,000 x 10<-7> cm<2> and structural uniformity are prepared by means of a combined impregnating and rolling process. An open-cell polymeric organic foam having an air permeability suitable to obtain the above air permeability of the ceramic foam and a ball rebound resilience of more than 25% is impregnated with a free-flowing aqueous slurry of a thixotropic ceramic composition and immediately afterwards passed through at least two controlled roll nips. The rolls are adjusted such that a brief compression of 50-90% during the first passage and a compression of 70-90% during the second passage are effected. The resulting material is thus uniformly impregnated with the desired quantity of slurry and is then dried and heated in order to remove the organic foam components. The ceramic foams can be successfully used as filters for molten metal, in particular for aluminium and aluminium alloys.

The glass frit obtained from the above composition may be communated the resultant particles having a surface area of 6000-12,000 sq. cm./ gm. and passing a sieve of 150 B.S. mesh and then applied to substrates which on firing produces a glaze. Such glazes are "metal-release free" or "metal release-resistant". By "metalrelease" is meant the transfer of certain metals, e.g., Pb and Cd, from a design layer via the glaze and/or from the glaze itself. The glaze is especially suitable for application as an "overglaze" on to glazed substrates bearing a decoration on the outer surface of the glazed substrate. The glazed substrate may be glass or a glazed ceramic substrate, e.g. glazed feldspathic porcelain, bone china or earthenware. The glaze together with the design may be applied simultaneously to the substrate as a decalcomania or transfer. Suitable firing temperatures for glazing glazed ceramic substrates are 720-800‹ C. In specific examples the glaze is applied to over-glaze enamels coloured with cobalt blue, iron oxide, cadmium sulphoseleride, cadmium red, chrome/cobalt/antimony green and cobalt silicate blue. Comparative examples describe the use of glazing composition comprising: (2) 20À0% PbO, 51À25% SiO 2 , 15À50% B 2 O 3 , 1À65% Na 2 O, 1À60% Li 2 O and 10À0% Al 2 O 3 ; and (5) 6À5% PbO, 44À05% SiO 2 , 12À3% B 2 O 3 , 6À75% Na 2 O, 1À35% Li 2 O, 1À01% Al 2 O 3 , 8À55% BaO, 4À40 ZrO 2  and 6À0% F 2 . The composition of the intial glaze applied to the substrate before applying the over-glaze of the invention comprises in a specific example 63À0% PbO, 5À1% B 2 O 3 , 21À0% SiO 2 , 1À3% Li 2 O, 3À4% Al 2 O 3 , 3À1% TiO 2  and 3À1% CaO.

The outer arms may be parallel before or after the inward stressing. Fig. 2 shows a retractive switch in which the median arm is normally biased to rest against an abutment 16 so that the moving contact 12 on the arm co-operates with a fixed contact 14. Downward pressure on the operating pin 17 causes the arm 4 to snap over and the contact 12 to co-operate with the contact 13, as shown. The switch may be arranged to be non-retractive and a further operating pin provided at the side of the abutment remote from the pin 17. The member 1 may be a bi-metallic element and thus responsive to temperature change.

Abstract: Tetrachloroethyl ethers of phenols of formula R1-(OCHCl.CCl3)n, where R1 is a substituted or unsubstituted member of the benzene series and n is 1 or 2, are prepared from dichlorovinyl ethers of formula R1-(OCH : CCl2)n by treatment with chlorine in the cold.  R1 may be substituted only by groups stable to chlorine in the cold, e.g. the phenol to be etherified may be phenol, 4 - nitrophenol, 4 - acetylaminophenol, cresols, methoxyphenols, 2 - methyl - 4 - chlorophenol, 4 - cyanophenol, 4 - thiocyanophenol, 4-hydroxybenzoic acid, hydroquinone, 4-bromophenol and p-hydroxydiphenyl.  An inert solvent may be used.  In an example, the tetrachloroethyl ether of p-chlorophenol is prepared by treating the dichlorovinyl ether in carbon tetrachloride with chlorine at about 10 DEG  C.  The ethers of 2 : 4- and 3 : 4-dichlorophenol and of 2 : 4 : 5-trichlorophenol are prepared in a similar manner.ALSO:Tetrachlooethyl ethers of formula R1-(OCHCL CL3)n when n is 1 or 2 and R1 is a substituted or unsubstituted member of the benzene series are used in compositions to combat insect pests, e.g., to protect floors, pelts, feathers and wool.

Title: Improvements in detectors for frequency-modulated radio-frequency energy
IPC: H03D9/04
Filed: 1941-06-17
Abstract: 547,473. Frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 17, 1941, No. 7652. Convention date June 18, 1940. [ Classes 40 (iii) and 40 (v)] Frequency-modulated waves are detected by feeding them to two oppositely-detuned resonant circuits the outputs of which are separately rectified and the resulting voltage variations are amplified in separate valve chains one of which contains an odd number of stages more than the other, and are then combined. The detector is described as a monitor for a short-wave television relay system. Energy is taken from the transmitting aerial or its feeder, and is applied by a transmission line 10 to the oppositely-detuned resonators 2, 4. Each of these is associated with a rectifier 40, 48 and load resistances 66, 68 which are connected in the grid circuits of amplifiers 70, 72. The output of valve 70 is fed to a further phase-reversing stage 90 and is then combined with the output of the valve 72 as the grid input of a two-stage amplifier 108, 116. Output is taken from the cathode impedance 120 of the last stage and is fed, by a low impedance line if desired, to a jack 124 into which a monitoring instrument may be plugged. Amplitude modulation may be detected by operating switches 131, 133 to cut out the valve 70. The input line 10 is loaded by a resistance 20 and its capacity to earth is tuned out by an inductance 26 which may be of the pot type. Voltage is fed to the de-tuned resonators by variable condensers 30, 36 and the tuning of the resonators is jointly adjusted by threaded members 61, 81 operated by a common control knob 9 and arranged to extend the inner members of the resonators. Unbalanced direct current output from the diode rectifiers may be used for automatic frequency control.
