Abstract: The enclosed method compresses a binary sequence BS = b1,b2,b3..., bN  wherein a run-length encoder (RLE) and two independent compressions are used. Let the output sequence of RLE be denoted with RLS. Ifb1=0 then RLS is 0, x0,y0,x1,.... If b1= 1 then RLS is 1, y0,x0,y1, .... Where xi is the length of i-th run with zeros and yj is the length of j-th run with ones in BS. RLS without b1 can be divided in two sequences RLS0 and RLS1 where:   $  RLS0= x0,x1, ...    $  RLS1= Y0,Y1,... . Let us donate the number of symbols in sequence X with  X , and the entropy of X with H(X). Then  X H(X) is the size of encoded X sequence. The inequalities:   $   RLS0 H(RLS0)+  RLS1 H (RLS1)  &   BS H(BS)   $   RLS0 H(RLS0)+ RLS1 H(RLS1)  &   RLS H(RLS) are proved.

Title: Improvements in or relating to method and means for steering aircraft with rotary wings
Inventor: MAILLARD FRANCIS
IPC: B64C27/32
Filed: 1948-04-15
Abstract: 654,309. Rotating wing aircraft. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. April 15, 1948, No. 10521. Convention date, April 17, 1947. [Class 4] [Also in Groups XXIV and XXIX] A device for steering rotating-wing aircraft having at least one rotor adapted to rotate relatively to the fuselage is characterized in that said rotor is carried by a rotary shaft in turn carried by the fuselage and connected through a transmission to a further rotary shaft also carried by the fuselage, the arrangement being such that no power is normally transferred through said transmission from any one shaft to the other, means being provided for transferring power through said transmission from any one shaft to the other, thereby giving rise to a reaction torque causing the aircraft to turn in the desired direction. In the embodiment illustrated the rotor blades 13, which are reaction propelled, are mounted on a hub 9 rotatively supported on a pylon on the fuselage 2. The hub 9 is provided with a gear ring 10 which meshes with a pinion 8 secured to one end of a shaft 7. The other end of the shaft 7 is connected to one element 6 of a torque-varying system 5 of which the other element 4 is connected by a transmission 3 to a source of power 14, shown as an engine for driving different accessories. In normal straight-line flight no power is transferred through the system 5 from the engine 14 to the rotor, but to cause the aircraft to turn in either direction the pilot increases or decreases the power supplied to the system 5 by the engine 14 so that torquereaction between the rotor and the fuselage causes a deflection from the normal flight path. In the embodiment shown the pitch of the rotor blades may be adjusted cyclically, but in a further embodiment (Fig. 1, not shown), the hub 9 may be universally mounted and instead of being reaction-propelled the blades may be provided with engines driving airscrews. Arrangements incorporating coaxial, longitudinally-disposed and transversely-disposed twin rotor systems are also described, together with mechanical, hydraulic and electrical arrangements of the torque-varying mechanism.

Title: Improvements in or relating to electrical integrating apparatus
IPC: G01J1/42
Filed: 1940-06-20
Abstract: 538,578. Photo-electric integrating photometers. SANGAMO WESTON, Ltd. June 20, 1940, No. 10637. Convention date, Jan. 10. Addition to 538,160, [Group XXXVI] [Class 40 (iii)] [Also in Group XXXVI] In an integrating photometer in which, as described in the parent Specification, a photo-cell co-operates with a polarized moving-coil relay and a reversing relay to generate impulses at a rate dependent upon the intensity of illumination, the reversing relay is ratchet-operated and the circuit includes a valve amplifier. As shown, Fig. 1, the moving contact of the moving-coil relay in either position modifies the bias normally applied to an A.C.-excited valve 8 to enable it to pass a current impulse. This impulse operates a counter 13 and the ratchet-operated relay 14 which reverses the connections of the photo-cell to the moving-coil relay. In a modification, Fig. 2 (not shown), the reversing relay has only one contact and connects the moving coil relay across one or other of two resistors connected in series to the photo-cell. In a further modification, Fig. 3, the reversing relay merely opens and closes a contact by which the moving coil relay is connected across one of two resistors in series with the photo-cell. A permanent connection across the other resistor is made via a third resistor 29. In this arrangement, the same magnet drives the counter and the reversing switch. The indicator of the counter comprises a pointer 34 frictionally coupled with its driving shaft 33 and moving over a scale 35 graduated in integral light values. It is manually set to a selected value and is driven counter-clockwise to return to its zero position when the integrated light value at the photo-cell 1 reaches the selected value. A switch 37 may be operated by the pointer when it reaches the zero position and may actuate a signal or control circuit.

IPC: G04B18/02
Abstract: 106,616. Ecaubert, F. May 25, 1916, [Convention date]. Balance regulators.-To obtain both range and delicacy in the adjustment, a secondary adjusting mechanism is carried by the primary one. The outer end of the hair-spring 21 being clamped to the end of the bridge 10 for the primary adjustment of its effective length, there is provided a turning-ring 11 with an ear 23 and an arm 19, the car carrying a curb-pin 26 and the arm 19 carrying a resilient finger 20 pressing the hair-spring against the curb-pin. The curb-pin projects eccentrically from a small turning-boss 24, which is the pivot of a pointer 25 reading a graduated arc 28 on the arm 19. The fine adjustment is made by the pointer, the curb-pin rolling on the hairspring to nip it at another point on the resilient finger. In a modification, the resilient finger is omitted, and the arm 19 is continued round to abut rigidly against the hair-spring. In another modification, the turning-bar is mounted in the end of the arm, instead of the ear, and the eccentric pin holds the hair-spring against the ear. In this case, the arm has a thinned bend, which gives it a certain amount of spring.
