Filed: 1946-05-29
Abstract: Foraminate cobalt aluminium catalysts are prepared by treating an alloy of cobalt and aluminium in relative proportion by weight of from 15 : 85 to 55 : 45 with an aqueous sodium or potassium hydroxide or carbonate or mixtures thereof so as to remove a portion at least of the aluminium from the surface and neighbouring regions.  The amount of aluminium extracted may be from 0.5 to 70 per cent by weight of it originally present in the alloy.  Reactivation of the catalyst is obtained by further repeated treatments with the alkaline extraction medium until the 70 per cent aluminium has been extracted. The catalyst may be used in hydrogenating dehydrogenating, hydrogenalysis and reductive amination processes.  Minor proportions of other metals may be present in the original alloy.

Title: Improvements in control apparatus for hydraulic circuits
IPC: F15B9/08
Filed: 1963-04-26
Abstract: 972,575. Fluid-pressure servomotor systems. ROBERT BOSCH G.m.b.H. April 26,1963 [April 28, 1962], No. 16427/63. Heading G3P. A hydralic actuator 7 operating e.g. an agricultural earth-moving implement is controlled by a valve apparatus comprising an exhaust valve 48 which is opened by an abutment 51 to exhaust the actuator on rightward movement of a pilot valve 19, and a plunger valve 36 controlled by the valve 19 within which it is slidable and controlling an exhaust passage from a conduit 2,12, 42 leading from a pump 3 past a pressure relief valve 18 and through a check valve 43 to the actuator. With the parts in the positions shown pump pressure in the conduit 12 and in an annular recess 13 can pass by way of external flats 33 on the valve 19 and holes 34 to a chamber within the valve 19 to hold the valve 36 against a loading spring 39 so that fluid from the pump can escape through holes 40 to a drain chamber 15. Leftward movement of the valve 19 cuts off the flats 33 from the recess 13 and connects them to drain through an annular groove 32 so that the valve 36 is moved by its spring to close the holes 40 and thereby cause the pumped fluid to open the check valve 43 and extend the actuator. Shock due to sudden closure of the valve 36 is prevented by the provision of a throttled escape path constituted by grooves 52 in the valve 19 and arranged to be closed if the valve moves sufficiently to the left. The escape path may include a throttled passage in the housing or it may be provided by longitudinal grooves in the valve 19 which are curved or stepped to give gradual closure. Actuation of the valve 19 is by a cam shaped element 23 interposed between a pin 20 on the valve and a lever 25 of a follow-up connection 27, 28, 29 from the actuator. As shown, the element 23 is eccentrically connected to the spindle 21 of a lever 22 for manual actuation but it may be operated by means responsive to the depth of the implement in the ground or its drag.

Abstract: 465,441. Loud - speakers ; cabinets. PHILCO RADIO & TELEVISION CORPORATION. June 12, 1936, No. 16445. Convention date, June 17, 1935. [Class 40 (iv.)] [Also in Group XL] In a loud-speaker cabinet or like soundreproducing apparatus, cabinet resonance at particular frequencies is diminished by the provision of one or more substantially freely movable tuned diaphragms, which are responsive to the frequencies it is desired to suppress and are mounted so as to be subject to considerable damping. In the construction shown in Fig. 2, three such sound-absorbing units 3, 3a are supported on the front wall 1 of a cabinet around a loud-speaker unit 2. Each unit 3, 3a comprises a tuned conical diaphragm 5 of parchment paper or the like secured at its apex to a disc 10 which in turn is fixed to a damping strip 6 of rubber or similar material. The strip 6 and the outer rim of the diaphragm 5 are attached to a supporting frame 4, the diaphragm for this purpose preferably being formed with integral corrugations 15 and an annular mounting ring 14, while the support 4 is itself mounted in an opening in the cabinet wall. In a modification, Fig. 6, the diaphragm 5 is connected by a rod 21 to a plate 20 located between layers 6a of felt or like damping material.

The 9-acyl- 3<SP>11</SP>-thiomethoxymethyl SF837 may be prepared by treating 9,2<SP>1</SP>-diacyl SF837 or 9-acyl SF837 having the general formula in which R 1  represents an acetyl or propionyl radical and R 2  represents a hydrogen atom or an acetyl or propionyl radical, with dimethylsulphoxide and acetic anhydride to obtain 9,2<SP>1</SP>- diacyl-3<SP>11</SP>-thiomethoxymethyl SF837 and treating this resulting compound with an alcohol or a water-containing solvent. The DMSO functions as the solvent for dissolving the reaction materials, but, additionally, other solvents inert to the reaction materials, e.g. benzene and toluene are also available as the solvent. The reaction may be conducted at room temperature to 50 C. The presence of pyridine considerably accelerates the reaction.

Filed: 1977-04-21
Abstract: 1524181 Fluid-pressure servomotor systems F GEMIGNANI 21 April 1977 [22 April 1976] 16722/77 Heading G3P The pressure in a vessel 2 acts through a normallyopen valve 14 and a line 9 on a piston 6 to hold a relief valve 4 closed. Excess pressure first closes the valve 14 by acting on a piston 22 to displace a rod 20 against a spring 25 and then opens a valve 32 by acting in a similar way on a piston 39, the space above the piston 6 being thus connected to a vent line 30 and the valve 4 opened to relieve the excess pressure. A cock 46 allows the space above the piston 6 to be vented manually. In a second embodiment, the normally-open valve (63) Fig. 7 (not shown) is arranged coaxially within a bore of the valve (60) which opens to vent the space above the piston 6 after the valve (63) has closed. Springs for loading the valves are also arranged coaxially and may be independently adjusted by screwed plugs (68, 70).
