Abstract: 665,234. Manure distributers. EZEE FLOW CORPORATION. July 19,1949. No. 19003/49. Class 6(i). Relates to fertilizer distributers of the type comprising a laterally-elongated wheeled hopper 34 having ports 53 in its base, the ports being partially obturated by a similarly-ported shutter 58 movably mounted below the hopper base. According to the invention, blades 114 mounted on a rotary agitator shaft 98 within the hopper sweep through the ports 53 to prevent clogging. As shown in Fig. 12, the ports 53 may include a slot 54 through which the blades 114 pass without interfering with the movement of the underlying shutter 58. The hopper, agitator shaft and shutter are made in two halves. Each wheel 97 drives one half of the agitator shaft 98, the inner ends being supported on a central bearing 102. The two halves of the shutter 57, 58 are simultaneously adjusted by a bellcrank 65 coupled to a hand-lever 75 which passes through a slot 80 in the draw-bar 78. The lever 75 may be clamped in any adjusted position by a stepped cam-like adjusting plate 87 (see Fig. 14). The blades 114 form part of feeding and agitating plates 113 which also include wings 115 intended to comminute the material and feed it towards the ports 53. Interspersed with the plates 113 are spiders 116 having oppositely-cranked blades 117, 118, adjacent blades being staggered around the axis of the shafts 98 so that the blades 117, 118 all lie upon helical loci, Fig. 7, (not shown).

Abstract: 1389377 Charging I C engines T G KEE 19 April 1973 [21 April 1972] 19115/73 Heading Fl  An I.C. engine including a crank-case and a cylinder block has at least a pair of pistons reciprocatable in unison in a pair of side by side parallel cylinders, the pistons being moved in unison to a t.d.c. position to induce gas into the crank-case and are movable in unison to a b.d.c. to displace the gas alternately into one or other of the cylinders for compression therein. On rising to t.d.c. the combusted gas in cylinder 14 is expelled via valve 32 and duct 34 whilst fresh gas is compressed in cylinder 16 for spark or compression ignition. Simultaneously gas is drawn through an induction valve (not shown) into the crankcase via inlets 36. The induction valve may be a reed, sleeve, disc or poppetvalve or the crank-shaft may act as a valve. On combustion in cylinder 16 pistons 18, 20 descend to drive the gas from the crank-case via a transfer passage 28 and valve 30 into cylinder 14. On rising again with valves 30, 32 closed the gas in cylinder 14 is compressed while valve 32 of cylinder 16 is opened to expel the combusted gas. Thereafter further firing in cylinder 14 causes both pistons to descend to repeat the cycle. The engine may consist of multiples of pairs and have one or more crank-shafts.

Title: Charge coupled circuits
IPC: G11C19/28
Filed: 1972-01-05
Abstract: 1377125 Charge coupled devices RCA CORPOBATION 5 Jan 1972 [14 Jan 1971] 20042/74 Divided out of 1377121 Heading H1K A pair of charge coupled shift registers containing complementary charge signals are read out by means of a differential detector circuit connected to corresponding stages of the registers. As shown, Fig. 10, the ends of a pair of shift registers represented by electrodes 14-n, 14-(n+1) and 14a-n, 14a-(n+1) are provided with "floating" regions F1 and F2 and share a common drain region D. Regions F1 and F2 are connected to electrodes 16-0 and 16a-0 of a second pair of shift registers and to a pair of MOS transistors 200, 201 which are cross-coupled to form a bi-stable. The pairs of shift registers are simultaneously clocked by two phase power supplies and carry complementary bits. During the #2 pulses charge signals representing a bit and its complement are shifted to the area of the substrate beneath electrodes 14-n and 14a-n and are received by floating regions F1 and F2. A quantity of charge representing a "1" raises the potential of one floating region while the absence of charge representing a "0" leaves the other floating region at a negative potential. These potentials unbalance the input to the bistable and control the state it assumes when control input VC1 is raised. Bias is applied to VR to form a channel between the floating regions F1, F2 and the drain which constitutes a pair of MOS transistors acting as load resistors for the bi-stable. During the #1 pulses the bistable provides bias for electrodes 16-0 and 16a-0 which selectively control the injection of charge into the second pair of shift registers while control electrodes 17, 17a are negatively biased. The circuit is then reset by making V R  negative to discharge the floating regions to potential V 4  and by making VCl equal to V 4  to cut off the transistors 200 and 201. The circuit arrangement is such that a "1" in the top left hand register (and a corresponding "0" in the top right hand register) controls the injection of a "0" in the bottom left hand register (and a "1" in the bottom right hand register). In a practical arrangement all four registers are formed in the same substrate with the pairs carrying complementary information arranged side-by-side. The transistors forming the bi-stable are also integrated into the substrate. In a modification, Fig. 11 (not shown), the floating regions are connected to the bi-stable via amplifying transistors and a further pair of transistors are provided by means of which external information can be injected into the second pair of registers.  The balanced detector may be utilized to provide a static output from the shift registers. Instead of using floating regions F1, F2 the input to the detector may be provided by Al electrodes capacitatively coupled to the charge transfer paths. The detector may also be utilized with 3 or 4 phase controlled shift registers.
