Title: Domain propagation device
IPC: G11C19/08
Filed: 1972-05-11
Abstract: 1383418 Moving domain devices RCA CORPORATION 11 May 1972 [17 May 1971] 22032/72 Heading H3B In a moving magnetic bubble domain device propagation of the domains is effected by a sonic wave passed through the device. Figs. 1 and 2 show a device having conventional bubble creation and detection looped conductors, though Hall effect or magnetoresistive detectors may be used; a glass or quartz substrate 10 supports a magnetostrictive film 20 on which bubble domain material 30 is supported by an SiO 2  film 32. At one end of the substrate a piezo-electric transducer 12 can produce sonic waves, while at the other end a device 19 absorbs such waves as pass through the substrate. The magnetostrictive film is usually magnetized along its easy axis of magnetization in the direction of arrows 21; the film is also shaped at 22 to provide successive stable domain sites. When a sonic wave passes along the substrate, the film 20 is stressed and its magnetization rotates. The arrow 21<SP>1</SP> shows the magnetization direction when the pulse has reached region 26 of the film. This rotation causes a domain in the film 30 to move to an adjacent site along the path defined by the shaped portions 22 of film 20. The shaped portions may be triangular rather than rectangular, or alternatively the film 20 may be replaced by a series of discrete regions of anisotropic magnetostrictive material.

Patent GB-817886-A (GB)
Title: Hydrocarbon conversion catalyst manufacture
IPC: B01J23/84
Filed: 1957-07-12
Abstract: A catalyst for use in the various hydrocarbon conversion reactions is prepared by slurrying in an aqueous medium at at least 100 DEG  F. a mixture of (a) a water-insoluble compound of iron, cobalt, nickel, copper or zinc, and (b) a water-insoluble acidic oxide of vanadium, niobium, molybdenum or tungsten, the resultant slurry is then mulled with a particulate catalyst base material and the mulled solids calcined.  The compound (a) is preferably a carbonate, bicarbonate, basic carbonate, oxide, hydrated oxide or hydroxide, and is present in an amount of 1-20 parts by weight calculated as the oxide and based on 100 parts of the finished catalyst; the compound (b) may be in the acid or anhydride form in an amount of 2-25 parts calculated as oxide. The slurrying temperature may be up to 212 DEG  F., higher temperatures require increased pressure, and mixing times of at least 10 minutes are used.  The catalyst base may be alumina, silica, magnesia, titania, zirconia, thoria or their mixtures in hydrogel or nonhydrogel form.  Alumina hydrates such as one containing 10-75 per cent of trihydrate, the remainder being monohydrate or amorphous, are particularly suitable, and may contain up to 25 per cent of silica, titania, zirconia, magnesia, thoria, boria or fluoride.  The mulling is essentially a dry mixing operation to give a mixture having the appearance of divided solids and the amount of water present should be regulated accordingly.  Preferably the water content of the mulled mixture is adjusted to provide an extrudable mass and is extruded to give particles 1/16 -\ba1/4 inch in diameter and 1/16 -1 inch long, or the mass can be tableted.  The catalyst may then be dried and calcined at 800-1200 DEG  F.  In examples: (1) cobalt carbonate and molybdene are slurried with boiling water for 10 minutes and alumina containing 30 per cent trihydrate, the remainder being boehmite and amorphous, added as a fine powder. The mixture was extruded, dried at 120 DEG  C. and calcined in flowing air at 900 DEG  C. for 6 hours; (2) nickel carbonate and vanadium pentoxide are slurried with water at 210 DEG  F. for 30 minutes and a silica-alumina (12 per cent Al2O3) hydrogel, partially dried to a water-content of about 65 per cent and ground, added, and the mixture was extruded, dried and calcined as in (1); (3) zinc carbonate and tungstic acid were slurried with water at 210 DEG  F. for 30 minutes and diatomaceous silica added and the mixture was extruded, dried and calcined as in (1).

Title: Improvements in or relating to electrical signalling systems
IPC: H04M15/08
Filed: 1946-07-25
Abstract: 615,271. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BAKER, G. T. July 25, 1946, No. 22136. [Class 40 (iv)] In a line identification system of the type described in Specification 614,177, the identification signals are transmitted from the subscriber's line circuit SLC to the outgoing relay set OGRS over one of the speaking wires. On seizure of the outgoing relay set AA operates and extends battery over the - wire to the distant incoming relay set, which when ready to receive the identification signals returns battery on the + wire to operate D. Relay S1 operates and locks to connect up and initiate the sending of the identification signals by, the equipment SLME. Relay SI also connects in a click absorbing condenser QA, provides a holding loop for AA and connects the secondary of the tone transformer TRG to the outgoing line. Contact dr1 vibrates to connect alternately 600 c.p.s. spacing tone to the transformer TRG and 750 c.p.s. tone to front contacts mw1 ... mz1 which operate successively to induce tone in leads M/T 1 ... 0 at instants during the sequence dependent on the digit characterized by the lead. The 750 c.p.s. tone signal characterizing the digit is sent from the appropriate lead over a strapping and a non-linear resistor ARB to the - speaking wire and thence to the tone transformer TRG. Battery E provides 100 v. biassing battery to render the non- linear resistances conducting to the identification signals. If the system is one in which reverse battery signalling is used the non- linear resistors are connected to the - wire of one half of the subscriber's lines and to the + wire of the other half, so that, assuming an exchange voltage of 50 v., the lead 11 will be at substantially - 25 v. and, except during identification, the biassing voltage of the non- linear resistors will be less than 25 v. which is insufficient to render them conducting. The non-linear resistors may be replaced by gasdischarge tubes.

Title: Pneumatic gauging equipment
Inventor: MARSH DAVID MALCOLM
IPC: G01L11/00
Filed: 1970-05-08
Abstract: 1282692 Measuring dimensions electrically T I (GROUP SERVICES) Ltd 4 May 1971 [8 May 1970] 22224/70 Headings G1N and G1U [Also in Division H3] To gauge the dimension of a workpiece air from a source is forced through a nozzle M, the back pressure in the nozzle being dependent on the dimension L. This pressure is applied to one side of a flexible diaphragm D whose other side is subjected to a back pressure controlled by a valve V which closes in dependence of the movement of the diaphragm. The diaphragm thus moves to an equilibrium portion dependent on the dimension L. In the invention the diaphragm itself directly closes the valve V, and is constituted by a metal or metalized material which forms, with a wall of the housing a capacitor whose value is indicative of the diaphragm displacement. The diaphragm may be a printed circuit board which may extend beyond the housing to carry the circuitry for measuring the capacitor. This capacitor, CD in Fig.3, controls the frequency of a multi-vibrator MV which feeds a diode rectifier circuit providing a current proportional to this frequency, the current being converted to a voltage by an amplifier E. The output is read on a meter MM which may be calibrated in length. This output may be fed to a "go; no-go" circuit in which upper and lower limits are set by potentiometers P1, P2, so that a lamp L1 or L2 lights up if the dimension is outside prescribed limits. A linear relationship between dimension and capacitance is achieved.
