Filed: 1967-06-22
Abstract: The caliper of a reaction-type disc brake is held in a U-shaped fixed member by springs having a specified shape including transverse portions which engage the caliper and in notches in the fixed member. The U-shaped fixed member shown has legs 4 and 6 on respective sides of the disc and connected by two webs 8 and 2. The two pad assemblies 14 and 16 are held radially in respective portions at 22 and abut the fixed member to take the braking torque.

Title: Multiple-break enclosed-type circuit interrupters with external rotary contact driving means and single chamber construction
IPC: H01H33/66
Filed: 1967-09-05
Abstract: A vacuum switch has two series connected contact pairs 5, 6 and 7, 8 operated simultaneously by a rotary shaft 16 outside of the evacuated envelope 2 and coupled to the movable contacts 5, 7 by members 10, 18 sealed to flexible bellows 12 in the wall 34 of the envelope. Each fixed contact member 20, 21 carries a screen 25, 26 protecting the outer insulating wall of the envelope while each movable contact member 10, 18 carries a screen 32 protecting the bellows. Further screens (30, 31) are attached to the flat ends of the cylindrical envelope (Fig. 2, not shown). The contact pairs may be used in parallel if required by making a connection to the operating shaft 16 (Fig. 3, not shown). In a modification (Fig. 4, not shown) the contact members 10, 18 are cranked outside the envelope so that deformation of the bellows is more nearly rectilinear alternatively (Fig. 7, not shown) pin-and-slot couplings (86, 86) may be introduced between the shaft 16 and the contact members which are guided for rectilinear movement only. In another modification (Fig. 5, not shown) only a single bellows is used, a single interconnecting member carrying both movable contacts four series connected pairs can be similarly arranged (Fig. 6, not shown). The envelope may alternatively be filled with SF 6 .

Title: Purification of antibiotic 833a
IPC: C12P9/00
Filed: 1968-09-14
Abstract: Antibiotic 833A, i.e. (-) (cis-1,2-epoxypropyl)- phosphonic acid, obtained according to Specification 1,223,923, is purified by stirring a solution of the antibiotic containing impurities with acid-washed alumina, filtering the resulting mixture, eluting the filtered alumina adsorbate with a basic aqueous or aqueous alcoholic solution and concentrating the eluate to produce a purified solution of the antibiotic. Antibiotic 833A may be in the form of an alkali metal, alkaline earth metal or ammonium salt or a salt with an organic base. Further purification is obtained by adding a C 1 -C 5 alkanol to the purified solution to precipitate insoluble material, filtering off the insolubles, passing the filtrate through a column of acidwashed alumina, eluting with a C 1 -C 5 alkanol gradient containing 2N ammonia and C 1 -C 5 alkanol, and finally ammonia, and lyophilizing the active fractions. Further purification is by dissolving solids in methanol, adding butanol, evaporating off the methanol and recovering the antibiotic from the butanol extract.
Patent ES-360456-A1 (ES)
Title: Pressure regulator device
IPC: G05D16/16
Filed: 1968-11-20
Abstract: A fluid pressure regulator comprises a perforated flexible disc 19 provided with a lip 26 which distorts relatively to a member 25 to regular flow from inlet 12 to outlet 13. Member 25 is connected by a stirrup 23 to an arm 41 of a helical wading spring 40, the arm 41 being also connected by a stirrup 59 to a diaphragm 52 which deflects in response to outlet pressure to adjust the position of member 25. The outlet pressure is normally connected to chamber 68 soley through a port 72, but should the pressure down stream of closure 19, 25 exceed that in chamber 68, a resilient bonnet 74 is deflected to increase the flow area between chambers 68, 71. Diaphragm 52 is connected to stirrup 59 by means of rigid discs 50, 57, stud 61 and spring 63. With this arrangement should the pressure in chamber 68 become sufficient to damage the diaphragm, stud end 65 is pressed against casing 51 to move disc 57 away from the diaphragm so venting chamber 68 through passages 62, 69.

When welding is used, the surfaces on opposite sides of the disc are ground parallel. Welding.-The plates are secured to the corrugated spacer by means of electron beam welding, whereby the assembled disc is rotated with the ridges preferably 0À01 inch from the adjacent plate and the beam is fixedly directed at an angle to intersect two or more adjacent ridges.
Patent ES-360652-A1 (ES)
Title: Improvements in and relating to gas-heated appliances
IPC: F23Q3/00
Filed: 1968-11-25
Abstract: An ignition safety device for gas-heated appliances which have a burner and an igniting device has a main switch 17 located at a distance from the burner, as well as a solenoidoperated valve 32 inserted in the gas supply conduit 34 and controlled by an electromagnetic relay 27 also controlling an operating contact 273, this relay 27 having an exciter coil 271 energized by the current supply system and a holding coil 272 energized by a thermocouple 29, there being a time-limiting device in the circuit in the form of a key contactor 20 and a Positive Temperature Coefficient resistor 24. As shown, the PTC resistor is placed between a rectifier 25 and the key contactor 20, the circuit is branched between the main switch 17 and the key contactor 20, the solenoid operated valve branch containing the operating contact 273 and a resistor 31. To operate the device, the main switch 17 is closed and then the key contactor pressed, which completes both the supervisory relay circuit and the ignition device circuit. Thus the exciter coil 271 is energized and the relay passes into its operating position, causing the operating contact 273 to close the circuit to valve 32, thereby opening the valve to gas flow. The gas is ignited by the sparks produced at the electrodes 42 of the ignition device 37, and when the resulting current produced in the thermocouple 29 has become sufficient to energize the holding coil 272 and thus maintain open the valve 32, the key contactor 20 may be released. In the case of failure of the gas supply or extinguishing of the flame, the thermocouple 29 is no longer heated, therefore it is unable to deliver sufficient current to the holding coil to maintain operating contact 273 closed, so the valve 32 is closed. If the gas is not ignited on pressing key contactor 20, after a time the resistance of PTC resistor 24 increases until it passes insufficient current to energize exciter coil 271, so that operating contact 273 is opened and valve 32 is closed. The ignition process cannot now be repeated until PTC resistor 24 has cooled.

Title: Mechanism for actuating pattern or control drums in knitting machines, and knitting machines incorporating the same
IPC: D04B15/66
Filed: 1971-06-08
Abstract: A cylindrical knitting machine has pattern control drums actuated by respective cam followers, themselves actuated by driven cams rigidly set in a carriage moveable axially of the cylinder. By virtue of the construction of the carriage and the setting of the cams in it only one cam follower can be actuated at any one time. Movement of the carriage is caused through a positive drive mechanism by radial movement of a carriage having driving cams. Only one of these may be engaged at any one time by an actuator disc, of which the axial position is adjustable by a lever linkage for which the control is a chain driven by movement of the cylinder, the chain having stops of different heights. According to the height of the stop sensed by the lever linkage the actuator disc is set axially, causing a corresponding radial set of the driving cam carriage and hence a corresponding axial set of the driven cam carriage. This has five positions, a neutral or non-driving position and two on each side of that: the chain has stops of five heights and there are five driving cams.
