Abstract: 1462370 Making internally finned tubing; corrugating tubes UNITED KINGDOM ATOMIC ENERGY AUTHORITY 11 Nov 1974 [30 Nov 1973] 55745/73 Headings B3A and B3E A method of forming one or more fins in the bore of a tube 2 comprises deforming the wall of the tube using one or more forming tools and causing relative movement between the tool or tools and the tube to form one or more grooves 3 in the outer surface of the tube and a corresponding protrusion or protrusions in its bore, and working the tube at least partially to close up the or each groove and cause the or each protrusion to be pushed inwardly into the bore to form a fin. The tube 2 is held by a clamp 12 and supported internally on a mandrel, both the clamp and the mandrel being free to rotate about the tube axis. Tube-deforming wheels 5 are adjusted relative to the tube axis, locked by set screws 10 and pressed down on to the tube by tightening screws 9. The tube 2 is then moved longitudinally and the wheels 5 form helical indentations in its surface, which are pressed into corresponding grooves in the mandrel. The tube is subsequently worked in a rotary ball or hammer type swaging machine. Alternatively it may be passed through reducing dies or rolls.

Title: Silo unloaders
IPC: B65G65/38
Filed: 1971-12-08
Abstract: 1373769 Conveying material BADGER NORTHLAND Inc 8 Dec 1971 [10 Dec 1970] 56894/71 Heading B8A Material is discharged from a silo by the action of a screw conveyer 26 and a discharge conveyer 32 in series feeding a discharge spout 68. The latter directs the material through windows 18 in the silo wall. The conveyer assembly is suspended by depending arms 52 which are connected at their upper ends (not shown) to a point on the central axis of the silo. The weight of the assembly thus tends to press a guide wheel 36 of the assembly into continuous contact with the silo wall. Torque reaction is resisted by an arm 62 having a telescopic section 64. Relative telescopic movement between these parts is necessary as the assembly rotates due to the fact that the rotation takes place relative to a rotary collar 50, the axis of which is offset relative to the silo axis. The spout 68 is connected to member 62 by a telescopically adjustable member 70, 72 (Fig. 2), and a yoke 80. The latter is connected to the silo wall by a bell crank 88 and chain 102. Thus as the assembly rotates, and produces relative movement of the members 62 and 64, the bell crank 88 is deflected and this raises the outlet of the spout 68 up and down. There may be two augers instead of one, as shown. Also there may be a chain conveyer instead of an auger. A cutter 30 loosens material adjacent the silo wall.

Title: Improvements in or relating to input circuit arrangements for transistors
IPC: H03H2/00
Filed: 1966-12-30
Abstract: 1,099,890. Transistor amplifying circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 30, 1966 [Dec. 30. 1965], No.58350/66. Heading H3T. The invention relates to a circuit in which a signal is applied from input terminals 2 to a transistor 5 in common base connection, through a coupling network, which matches the input impedance of the circuit to the impedance Ra of the source and also provides a substantially optimum noise level in the transistor. The coupling network incorporates a resonant circuit L 0 , C 0 , having in parallel therewith at least one element, e.g. the circuit losses R 0  capable of dissipating a portion of the power of the signal. According to the invention, the transistor is coupled to the resonant circuit by means which serve as a transformation network inverting the input impedance of the transistor; as shown, the means comprise inductor L which, at the operating frequency has a reactance several times greater than the input impedance of the transistor. Also as shown, the source which comprises an aerial is matched into the circuit by means of series capacitor Ca. In a modification, operating on two widely separated frequency bands, the inductor L functions on the higher band and a series-connected capacitor is operative on the lower band; the capacitor Ca is also operative on the higher frequency band, being shunted by an inductor for the lower band (Fig. 16, not shown). The inductance L may comprise the leakage inductance of a loosely-coupled transformer (Fig. 13b, not shown); alternatively, a pair of series-connected inductances or series-connected capacitors with the transistor connected to the tapping point may be used (Figs. 12, 14, not shown); the capacitor Ca may also be supplemented by a capacitor connected across the source (Fig. 14, not shown). The arrangement is stated to reduce the damping on the tuned circuit and also the variation in damping as the bias on the transistor is varied for gaincontrol purposes.

Title: Master-slave type j-k flip-flop circuits

IPC: H03K3/037
Filed: 1968-12-12
Abstract: 1,253,379. Transistor bi-stable. TOKYO SHIBAURA ELECTRIC CO. Ltd. 12 Dec., 1968 [12 Dec., 1967], No. 59057/68. Heading H3T. A J-K master-slave flip-flop using current switching circuits where current is switched from one path to another, and having for example J and K, and S and R (set and reset) inputs, has a Cp (clock) input applied to the master flip-flop 114, 116 which also receives through current switching circuits the outputs Qs, Qs of the slave; while the slave flip-flop 211, 212 receives through further current switching circuits the outputs Qm, Qm of the master and also receives the block signals Cp. The collector resistors 104, 110, 203, 208 of the flip-flop transistors 114, 116, 211, 212 are connected to emitter followers 121, 124, 217, 222 for crosscoupling. The transistors 114, 116 of the master are emitter-coupled with transistors 113, 304 and 115, 309 respectively to form NOR gates (for positive signals), which respond to the flipflop positive feedback signals, to the R and S inputs, and to the signals from emitter followers 303, 308 derived from the J, Cp and Qs and the K, Cp and Qs signals respectively. The emitter follower 303 produces a positive signal when transistor 302 turns OFF and transistor 103 ON in response to J and Cp being negative and Qs being positive, the state of these transistors 302, 103 being respectively ON and OFF for all other inputs; the emitter follower 308 operates similarly. In the slave flip-flop transistors 404, 409 similarly form NOR gates with flip-flop transistors 211, 212, and the inputs to 404, 409 are from emitter followers 403, 408; the emitter follower 403 gives a positive output when the input Cp to transistor 202 is negative and the input Qm to 201 is positive, but not otherwise; emitter follower 408 operates similarly. For starting conditions J=Qm=Qs=L (low) and K=Qw=Qs=Cp=H (high) (Fig. 2, not shown), then 116 is ON, 114 OFF, 212 ON, 211 OFF. When Cp goes L, emitter follower 303 output goes H, turning 304 ON; the collector of 304 is now L and this via transistor 121 turns 116 OFF, and the master flip-flop is switched over. No change in the slave flip-flop occurs until the end of Cp when the H at 202 base and the now L (Qm) at 201 base cause emitter follower 403 output to go H and turn 212 ON by means of emitter follower 217; the slave is now changed over. A simpler embodiment (Fig. 3, not shown) dispenses with some of the emitter followers, reduces the number of transistors involved in some of the gating functions, but operates basically in the same manner. The current switching circuits are emitter coupled circuits.
