Title: Pressure or temperature responsive switch
Inventor: JUNK MARTIN
IPC: H01H35/26
Filed: 1982-06-07
Abstract: A pressure or temperature responsive electrical switch has a spindle 2 and a linkage for converting a rotation of the spindle into a linear motion parallel to the spindle for actuating a stationary microswitch 22. The linkage comprises a body part 4 fixed on the spindle 2 and a bistable sector 30 which is pivotable into one of two stable positions by means of a spigot 9 on the body part 4. When the sector 30 is pivoted a sleeve 16 is axially moved via a cam mechanism 33 to cause a lever 21 to be pivoted and actuate the microswitch 22. The body part 4 can be turned through more than 180 DEG  with respect to the sector 30 in either of its positions without effecting a further switching action. The pivotable sector 30 is carried on a setting member 14 which is rotatable into a desired position, together with the sleeve 16, by means of an adjusting spindle 11. <IMAGE>

Title: Apparatus for fitting valved bags to be filled onto filling connections of a packing machine
Inventor: SCHWAKE PAUL
IPC: B65B43/26
Filed: 1982-12-03
Abstract: Valved bags 1 which are to be filled by means of a filling machine 17 are taken from a store, and individually fitted onto filling connections 21 of the filling machine 17. Each separated bag 1 is conveyed to the filling connection 21 by a conveyor 5, 8 in a rectilinear movement. The valve is opened by the operation of separating the individual bag and is disposed in alignment with the filling connection 21, during the conveying motion. The operation of fitting the bag onto the filling connection 21 takes place in three steps which occur simultaneously for three successive bags. In the first step, by means of pivotal suction members, the bag is drawn from the store and at the same time the valve is opened, in the second step, the bag is moved towards the filling connection 21, into a waiting position, by means of cooperating roller/belt conveyor 5, 8, and in the third step the bag is moved from the waiting position and fitted onto the filling connection 21. The valve is held in the opened position during the conveying movement by pivotally mounted guide plates 13 and 14 which, after fitting of the valve on the filling connection, can be pivoted apart to avoid influence with the applied bag. When the bag fitting apparatus is used with a rotary packing machine, the fitting apparatus is arranged in the form of an operating unit on a carrier 9 which is pivotal about a vertical axis 41. During the movement of conveying a bag from the waiting position into the filling position, the fitting apparatus is pivoted by an entrainment member 23 arranged on the filling connection engaging an entrainment lever 20. <IMAGE>

Abstract: Internally-grooved tubular members (10, 12), for example sections of a tubular casing for disposition in the earth to receive and guide geophysical instruments, are coupled together end-to-end by snap-action couplings. An open-ended coupling sleeve (14) has a central internal shouldered circumferential recess (36) which interlocks with a shouldered external segmental collar (26) on the end of a nipple (16) of reduced diameter constituting an end portion of each tubular (10, 12).

Title: Armour piercing projectile
Inventor: GUSTAVSSON HANS
IPC: F42B12/10
Filed: 1984-05-11
Abstract: This invention relates to a new type of armour piercing projectile which has a warhead which functions according to the hollow charge principle. According to the invention the warhead is composed of at least two separate hollow charges (4 and 5) located one behind the other and non-permanently joined to each other, and each having its own igniter device (16) and (22). The warhead according to the invention also includes a separation charge (14) with its own igniter device (13) for the purpose of separating the hollow charges without altering the course towards the target of either of the charges while the said charges are in trajectory. The hollow charges create an effect in the target at a certain interval in time after each other, and thereby enhance the penetration of the projectile into thick conventional armour, or active, dynamic and composite armour. <IMAGE>

Title: Telephone exchanges
Inventor: HARLAND GEOFFREY
IPC: H04Q11/04
Filed: 1984-05-25
Abstract: In our Application No. 8406721 (C.D. Pratt 2) we have described and claimed a system in which a non-digital exchange is enhanced to give some subscribers access to facilities normally only available on a digital exchange. This uses a front-end switch for a group of such "enhanced" lines, which switch connects those lines to a lesser-numbered group of terminations on the non-digital exchange. In the present arrangement, in which the front end switch (5) is a digital arrangement, the front-end switch has access to TDM/PCM busses 6 to a remote digital exchange. If the number of enhanced subscribers warrants, two or more front end switches are used with access for the lines on the front-end switch or switches, to the junctions to the remote digital exchange via a further digital switch network. As described the non-digital exchange is TXE4 or TXE4A, the digital exchange is System X, and the first digital switch is based on the OCS 300 small exchange. <IMAGE>
