Title: Unit type curtain wall assembly
Inventor: GARTNER KARL
IPC: E04B2/96
Filed: 1983-08-10
Abstract: A plurality of standardized curtain wall units (A Fig. 2) of rectangular shape are arranged in rows and columns, with a predetermined gap G between the opposed side frame members 1 of every two horizontally adjoining curtain wall units A. For closing the gap G so as to allow relative displacement of the individual curtain wall units A in their own plane, three sealing bands 5, 6, 7 of elastic material each have their lateral marginal edge portions engaged in a respective pair of opposed mounting grooves 8, 19, 35 in the opposed side frame members 1 of every two horizontally adjoining curtain wall units A. Each sealing band 5, 6, 7 has a width less than the distance between the bottoms 8a, 19a, 35a of the pair of opposed mounting grooves 8, 19, 35 in which the sealing band is engaged. Thus assembled unit type curtain wall assembly has a room temperature control function, with passageways 15, 17 for conditioning air and hot or cold water extending longitudinally through the side frame members 1 of each curtain wall unit A. The three sealing bands 5, 6, 7 are one (5) on the indoor side of the gap G and the other (6, 7) on the outdoor side of the gap G. <IMAGE>

Title: Radars
Inventor: DONALDSON DENNIS
IPC: G01S13/44
Filed: 1984-08-23
Abstract: The well-known problem of the so-called "multi-path" effect, in which radar energy signals traveling between the radar and a target can propagate along two or more different pathways so that the radar is unable to distinguish between these, is met by using a frequency-agile system. It transmits within a short time period a multiplicity of radar signal sequences each at a different frequency and then averages the returned, received, signals (or some value representative thereof) over a similar short time period to give an indication of the true position of the target relative to the reflective surface. <IMAGE>

Patent GB-2173484-A (GB)
Title: Sheet stacker
Inventor: STEMMLE DENIS JOSEPH
IPC: B65H29/14
Filed: 1985-04-23
Abstract: Sheet stacking apparatus for handling simplex and duplex copy sheets has both inverting and non- inverting copy sheet paths (6a, 6b) which can be selected by moving a diverter (7) between two positions. in one position (7a) the copy sheet is directed along guide branch (6a) into slots (9) of the disc inverter (8) which rotates to invert the sheet. The sheet is advanced by nip rolls (32a, 32b) at the output end of the inverting path (6a). An upwardly inclined collection tray (10) has a backstop (30) located in the path of the inverted sheet, but with recesses (20) which allow the discs (8) to pass freely. The lead edge of the sheet is brought to rest when it abuts the backstop (30). Nip rolls (32a, 32b) continue to advance the sheet until its trail edge exits the rolls (32a, 32b) and thus it is delivered into the collection tray (10) inverted. In the other position (7b) the diverter (7) directs the sheets along guide branch (6b) to nip rolls (3a, 3b) which feed the sheet without inversion directly into the tray (10). The discs (8) have concave cut-away portions (18) so as not to foul the non-inverting sheet path (6b). The stacker may be used as a moving-bin sorter in which case the discs (8) have flat sides (28) to prevent fouling the path of movable collection trays, i.e. bins, as they pass by. <IMAGE>

Title: Mounting of bearing and shaft
Inventor: WRIGHT HAROLD T
IPC: F16C23/10
Filed: 1985-08-21
Abstract: To provide radial stability of a bearing (12) on a shaft (11), the bearing is made slightly larger than the shaft and then biased so that the bearing engages the shaft at one point and is spaced therefrom diametrically opposite that point. One means to bias the bearing is the use of an elastomeric ring which is thicker on one side (19) than the other (18). Another means is the location of a spring in the shaft which biases the bearing along one radial line. The spring may be a leaf spring installed in a keyway-like slot (Fig. 4, not shown) or a helical spring in a radial bore (Fig. 6, not shown). <IMAGE>
Patent GB-2180597-A (GB)
Title: Valve control
Inventor: SUMMERLIN FREDERICK ARTHUR
IPC: F01L13/00
Filed: 1985-09-13
Abstract: Apparatus controlling the opening and closing of a valve 16 in accordance with the relative phase of two cams 25, 26 each fixedly mounted on one of two separate, contra-rotating, camshafts 22, 23 respectively, includes a dual cam- follower 27 having two spaced-apart contact positions 31, 32 for contacting the two cams respectively. The dual cam-follower 27 is pivoted at its centre 28 to an intermediate member 29, which is mounted on the top end of the valve- stem 35. There is lost motion between them against a spring 47. When the contact position 32 is riding on the high-lift lobe 54 of the cam 26, the lost motion is taken up and any increase in lift of contact position 31 due to cam 25 depresses the valve stem and opens the valve. <IMAGE>

Patent GB-2174251-A (GB)
Title: Coupler for transmission lines
Inventor: ALEXANDER MARTIN
IPC: H01Q9/06
Filed: 1985-12-19
Abstract: A conductive element 11 is used to suppress unwanted modes introduced at a transition between a coaxial line and a triplate line. The element 11 is U-shaped and partly encloses the end of the triplate line. The arms of the U are spaced from the triplate line by a distance which is ideally about twice the ground plane spacing according to conventional theory. The centre of the U shape is however spaced by a smaller distance. This matches the transition over a broad frequency band without resort to complicated matching aids. <IMAGE>
Patent GB-2186736-A (GB)
Title: Ion beam arrangement
Inventor: BARRETT NEIL JOHN
IPC: H01J37/08
Filed: 1986-02-13
Abstract: In an ion beam arrangement a steady beam of ions from an ion source (not shown) is subject to a relatively small, eg. 21 DIVIDED 2 KV, high frequency alternating potential in an ion beam buncher 2 to impart a velocity modulation to ions within the steady beam. The beam then passes through drift tube 3 of such length, eg. so the ions have a transit time of 6 cycles of the HF signal, that the velocity modulation results in the formation of the discrete bunches of ions, but without any overall increase in ion energy. These ion bunches can then be accelerated to high energy levels using a multistage alternating voltage linear accelerator, two stages 24,25 of which are shown, the accelerating electrodes 4,26,27 having a relatively high, eg. 50 KV, HF alternating potential applied thereto. The pre-bunching of the ions before the accelerator stages results in much increased efficiency. The drift tube 3 may have internal electrostatic focussing elements 20-23, and phase variation between HF tubes 2 and 4 may be compensated by the variable d.c. voltage applied to drift tube 3 from source 32. <IMAGE>
