Title: A key holder
IPC: E05B11/00
Filed: 1980-03-24
Abstract: A key holder for holding keys which may be used to operate devices such as valves or switches. The holder has three mechanisms 36, 37 and 38 each of which may receive a specific key, and which prevents withdrawal of the key once the mechanism has been turned by the key. Turning the mechanism rotates a cam plate 44 having a crescent-shaped cut-out in which, when one plate has appropriately been positioned, may be received the adjacent cam plate. All keys may be locked in position by locking mechanism 36 by a peg 35 provided on a shaft 33, rotatable by a key-operated cylinder lock 32. The key for lock 32 may be removed only when all three mechanisms 36, 37 and 38' contain keys and have been turned to prevent withdrawal of those keys: conversely, the keys of mechanisms 36, 37 and 38 may be removed by turning the mechanisms one at a time in sequence only when lock 32 has been turned by its key to remove peg 35 from the associated cam plate, that key then being held in lock 32. <IMAGE>

Patent GB-805981-A (GB)
Abstract: 805,981. Sparking plugs. GENERAL MOTORS CORPORATION. April 16, 1956 April 15, 1955], No. 11450/56. Class 7(4) A sparking plug, particularly for use with gas turbine engines, has a tubular metal shell within which is secured an insulator comprising two elongated substantially cylindrical sections, each of which is composed of ceramic material, and one of which is bonded at one end to an end of the other so that the ends of the insulator and the shell are in substantial axial alignment, the ends of the metal shell being substantially coextensive with or projecting beyond the ends of the insulator. The upper and lower sections 24, 26 of the insulator are formed in known manner for example by injection or compression moulding using an organic resin as a binder which is subsequently burned out during the firing operation; by the rubber moulding technique using paraffin as a binder which is burned out during firing or by grinding or turning. The insulator is preferably made from a sintered high alumina composition. At least those portions of the insulator sections 24 and 26 to be joined are coated with a thin layer of ceramic bonding material and fired until the material is fully matured. After cooling at least the mating portion of one of the sections 24 or 26 is coated with a second layer of ceramic bonding material after which the two sections are fitted together and fired while pressure is applied. The pressure may be 3 to 4 pounds. The centre electrode may be filled before the firing operation. A variety of ceramic bonding materials can be used ranging from those which mature at the relatively low temperature of about 1600‹F. to those which mature at the relatively high temperature of about 2500‹F. The composition of a preferred known low temperature maturing glaze is quoted. The final step in the plug manufacture is a weld operation whereby the thin shell section 54 is softened by passage of electric current while pressure is applied on the ends of the shell so as to tightly clamp the insulator shoulder 25 between the shield 14 and sleeve 27 and firmly seat the base of the insulator against the flange 22. A conductive glass seal is indicated at 34. Fig. 4 shows a modification. The plug includes seals 78, 80. The insulator is seated and sealed within the shell by means of a gasket 86 and by a gasket 90 which is pressed between the top surface of the insulator and the shell. The shell sections may be secured together by welding or brazing.

Title: Chlorine dioxide production using mixed acid feed
IPC: C01B17/96
Filed: 1981-11-17
Abstract: A mixture of hydrochloric acid and sulphuric acid for use in a chlorine dioxide generating process is produced by reacting chlorine formed with the chlorine dioxide in the chlorine dioxide generating process with sulphur dioxide and water. The substantial evaporation of the water which would otherwise result from the exothermic nature of the reaction is prevented by controlling the temperature of the liquid below boiling point during the reaction, e.g. by effecting the reaction in a cooled falling film absorber having integral cooling passages and to which liquid water is fed to form the falling film or by recycling a substantial proportion of the product acid through an external heat exchanger and diluting it with water.

Title: Clamping device for a machine for testing materials
Inventor: POHL ANDREAS
IPC: G01N3/02
Filed: 1982-06-17
Abstract: In a clamping device for machines for carrying out alternating stress and alternating elongation tests at high temperatures on materials, the clamped ends of the material test piece in each case are tensioned in a clamping element with a loading element. The tensioning must be adapted at high temperatures to the lessening strength of the clamping element. For the automatic adaptation of the tensioning, the loading element (7) consists of a compression- resistant material, which has a lower coefficient of expansion than the material of the clamping elements (6) for the test piece (3). In addition, spring means with a degressive characteristic curve (Fig. 2 not shown) is provided for producing the initial stress on the loading element. Through making use of the differing linear expansion behaviours of the loading element (7) and of the clamping element (6) in connection with a spring (9) with a degressive characteristic curve an automatic adaptation of the expansion force Fv to the strength of the clamping element (6) at high temperature is possible.   <IMAGE>
