The drive unit includes a pair of large eccentric weights 9 and a pair of small eccentric weights 11 releasably and eccentrically adjustably secured to arms 8, 10 which are in turn vertically adjustably mounted on parallel shafts 6, 7, the small weights rotating at twice the speed of the large weights. The coupling 2 comprises a first member 20 secured to the drive unit 3 and having a threaded shank 21 engaged in a threaded socket of a second member 23 secured to the table 1 and a lock nut 22 on the shank 21 to lock the two members against relative rotation and axial movement. An eye member 25 to which a cable may be connected has a threaded shank 26 with a lock nut 27, the shank being threaded into a socket member 28 fixed to the table 1 By slackening the locknuts 22 and 27 the table may be inclined sideways to any desired position. The concentractor may be inclined longitudinally by varying the length of the cables. The table 1 may have coarse riffles 30, Fig. 4, on one side and fine riffles 30a on the other side and the table may be turned through 180 to change from one riffle pattern to the other. The table may be made with a skeletal frame shown dotted in Fig. 1. By replacing one of the riffle surfaces with a mesh, air agitation of the material being treated can be achieved by introducing compressed air into compartments 31 which may be interconnected by apertures through the skeletal frame members 32. Gutters for collecting material washed sideways and lengthways of the table are provided at 35 and 36 respectively. A cable may be provided at the table corner 34 and a further cable may be secured to the drive unit 3. A number of tables may be rigidly coupled to a common drive unit.

Patent GB-1551172-A (GB)
Title: Address-free fault location for digital transmission links
IPC: H04B17/40
Filed: 1977-11-22
Abstract: For consecutive loop closure formation in the intermediate stations of a digital transmission path, an initialising signal is transmitted to all the regenerators (Reg A1 ... Reg An) of one call direction, followed within a specific time period by the transmission of a further signal containing a loop closure command. The loop circuit is formed in the first regenerative repeater (ZWR1) by the loop closure command, and an initialising signal transmitter (Q11) is simultaneously activated which transmits an initialising signal to the next regenerators (Reg A2 ... Reg An). Due to a short-time interruption of the transmission of the loop closure command, the loop closure is interrupted in the first regenerative repeater (ZWR1) and formed in the next regenerative repeater (ZWR2). The loop closure is forwarded via the transmission path through further interruptions of the transmission of the loop closure command. <IMAGE>

[Also in Division H1] In a microwave heating device comprising a serpentine waveguide formed by two trays hinged together, each tray is formed from a plurality of metal bars 11 interleaved with a plurality of removable upstanding, metal wall elements 12, and a plurality of metal blocks 15, each of which is seated on the ends of two adjacent metal bars 11. The bars 11, removable wall elements 12 and metal end blocks 15 define a serpentine channel and are secured together by tie-rods 18 and to channel section members 17 by bolts 16. Adjacent wall elements 12 are arranged with their stepped ends 13 (Fig. 2) reversed so that a gap is provided between the wall element andmetal block 15. Both trays, only one being shown in Fig. 1, are mounted on a hinge plate 21 so that when the trays are closed a slot is formed transverse to wall elements 12 through which paper or sheet material may be passed. A safety switch cuts off the microwave supply when the trays are opened for the insertion of sheet material. The hinge plates are slotted at 24 for connection to a magnetron and water load respectively. The magnetron may be matched to its aperture 24 by means of a tapered transition or by means of a quarterwave step-transformer (Fig. 5, not shown). An adjustable matching stub may be provided to allow the water load (Fig. 6, not shown) to be matched with the waveguide. The bars 11 are provided with holes 30 through which air is blown on to the sheet material to remove vapour. The air is preferably preheated by an infra-red heating element before being passed through the holes 30 which are preferably fitted with nozzles to function as an " air knife." The bars 11 may be replaced with rectangular tubes having air holes on their inner sides.

When the adapter is attached to the camera 10, upon depression of a shutter release member 14 thereof, an end portion 20 of a activating member 19 hits the conductor 38, which is resilient and so is moved into contact with the conductor 39 to complete the circuit to the appropriate flash-lamp 34 As an alternative, Fig. 7 (not shown) the member (19) may be electrically connected to the conductor (102), and the conductor (101) need not be resilient. The activating member 19 normally hits the primer tube of, or releases a striker to hit the primer tube of, a bulb of a percussion ignitable flash unit when the adapter is not in use. Operation of the camera 16 will rotate the socket 16 thereof, and hence the adapter 30 and its flash unit 33 when they are in use. In another embodiment, Fig.4 (not shown) the adapter (50) is connected to the camera socket by a power cord (61) and a plug (62), which is prevented from rotating with the camera socket. The flash unit (54) on the adapter is rotated either manually or in response to depression of the shutter release (14) there being an electromagnet (77) Fig. 5 (not shown) which, when energized, attracts a member (79) thereby freeing a socket rotator (71).
