Title: Method of and apparatus for producing asbestos-rubber gasket  sheets
IPC: F16J15/10
Filed: 1971-06-16
Abstract: 1322296 Calendering asbestos-rubber REINZ DICHTUNGS-GmbH 16 June 1971 [29 June 1970] 28265/71 Heading B5A Asbestos-rubber gasket sheet is calendered in long lengths by means of an apparatus comprising a pair of rolls 2, 3 the lower of which is heated and the other cooled, with a steel belt 5 passing between them and over a reversing roll 9 which may also be heated. The ends of the belt are attached to take-up drums 10 and 10a, these being driven, at a linear speed corresponding to the linear speed of the calendering rolls, first in one direction so that the belt is drawn off drum 10a and taken up by drum 10, and then the reverse. When the belt and roll direction is reversed the roll 9 is moved up the slide 7 into the idle position shown in broken lines and the roll 9a is moved down into the operative position shown in broken lines; thus maintaining the delivery section of the belt in maximum contact with the heated roll 3. The asbestosrubber mixture is fed into the roll gap 1 between the upper roll 2 and the belt which is heated by its contact with roll 3 and also roll 9. Repeated reversal of the traverse of the belt through the gap is effected until the rubber sheet has cured, further mixture being supplied to the reverse side of the gap, as at 6, if necessary to obtain a uniform sheet. By appropriately dimensioning the belt, sheets of any desired length may be obtained, and a single belt may traverse a series of pairs of calender rolls to obtain very long sheets. In an alternative arrangement of the apparatus (Fig. 2, not shown) the reversing rolls 9, 9a are moved up and down by pivoted arms instead of sliding as in the Fig. 1 embodiment.

Title: Electrical switch
IPC: F41A19/58
Filed: 1970-06-11
Abstract: 1430228 Press-button retractive switches HECKLER & KOCH GmbH 11 June 1970 [13 June 1969] 28427/70 Heading H1N A push-button switch intended for triggering an electrically-ignited weapon comprises, Figs. 1, 2, 5, an insulating housing 1 closed by an end wall 2 carrying five equi-spaced circularly arranged fixed contacts 3, a further contact 7 being located at the centre of the end wall. A switching member 31 of conducting material has a projection 33 which successively engages the contacts 3 upon successive operations of the push-button 21 to establish connection with the contact 7 via a conducting and biasing spring 34. A stronger spring 35 transmits the motion of button 21 to the member 31. To obtain the step-wise rotary movement of the contact 33 a control sleeve 11 is fixed within the housing 1, this sleeve having five slots 12 in alignment with the contacts 3. The slots 12 serve as guides for arms 22 on the button 21 and also for arms 32 on the switching member 31 when the member is not displaced by the button as in Figs. 1, 2. The sleeve 11 has inclined cam surfaces 14 extending between the slots 12 and similarlyinclined surfaces 23, 37 are formed on the ends of the arms 22, 32. The projection 33, constituting the moving contact, is formed by an extension of one of the arms 32 so that when the button is pressed the spring 34 is compressed and the contact 33 engages the fixed contact 3 situated thereabove as shown in Fig. 5. On further depression of the button 21 the spring 35 is compressed so that surfaces 23 of the arms 22 engage the surfaces 37 of the arms 32 (Fig. 6, not shown) and since the arms 32 are clear of the slots 12 the torque exerted on the switching member 31 causes it to commence rotation, cleaning the contacts 3, 7, whereby on release of the button the springs 34, 35 expand, the button returns, and the arms 32 slide over the surfaces 14 into the succeeding slots 12. Thus the next depression of the button causes the contact 33 to engage the succeeding contact 3. In a modification, Figs. 7, 8, the centre contact 7 is omitted and a contact 51 surrounding the housing 1 makes contact with the switching member 31 through a web 52 and conductive sleeve 11. The fixed contacts 3 are slightly offset from the slots 12 as shown in Fig. 8. On depression of the push-button the contact 33 engages the side of a contact 3 under pressure due to the torque exerted by the engagement of the surfaces 23 with the surfaces 37. The switch is made watertight by a cover 54 and bellows 59.
