IPC: B64C13/24
Filed: 1953-01-30
Abstract: 749,253. Controlling aircraft. NORTHROP AIRCRAFT, Inc. Jan. 30, 1953, No. 2713/53. Class 4. A control system for an aircraft having an elevation controlling surface operated by a pilot's control element without exerting feelback forces on the element, includes means for creating a first force varying in accordance with airspeed, means for creating a second force varying with normal accelerations of the aircraft, means for applying the first force to centre the pilot's control element, and means for applying the second force to modify the effect of the first force in a direction tending to move the control element to reduce normal acceleration. As shown in Fig. 3, the control stick 6 pivots about an axis 13, and the lower end of a trunnion block 10 is connected to a support 26 having a forwardly extending leg carrying a bob weight 28. A balance spring assembly 29 is connected between the leg and a bracket 30 on the aircraft structure and comprises a tension rod 32 surrounded by a compression spring 33; the spring assembly is provided with adjustment fittings 40, 41 by means of which the pull of the spring may be adjusted to a predetermined value at a given control stick position. The angle A between the axis of the spring assembly and its movement arm about the stick pivot 13 is preferably designed to be 90 degrees at some position within the normal range of stick movement, and the combination of the spring and the bob weight serves to detect normal acceleration and apply a restoring force to the stick. Attached to the support 26 is a bracket 45 connected by a link 46 to a lever 47 pivoted at one end about a bracket secured to the aircraft structure and connected at the other end to a connecting rod 49 connected to a bellows shaft 50 of a force bellows. The bellows comprises a diaphragm 55 subjected at one side to static pressure and at the other to dynamic air pressure. Thus a force is applied to the control stick which varies approximately as the square of the airspeed and which increases with displacement of the stick from neutral position.

Title: Improvements in methods and apparatus for radio receiving
IPC: H03J7/30
Filed: 1941-02-28
Abstract: 549,771. Wireless receiving apparatus. WHITE, S. Y. Feb. 28, 1941, No. 2756. Convention date, Feb. 29, 1940. [Class 40 (v)] A device for attachment to radio receivers of the kind including a tone filter tuned to a predetermined frequency and arranged to operate a multi-position switch in response to impulses received in the tone filter is characterized in that for the identification of stations transmitting carriers containing identifying modulation impulses in addition to the signal modulations, the multi-position switch is arranged to move an arm into predetermined positions wherein said arm can act as an indicator and to complete the circuit of a visual or audible indicating mechanism to warn a signal receiving operator. In Fig. 2 R is a receiver of the kind described in Specification 549,770 adapted to lock on to a carrier modulated by a predetermined tone. Coupled to the output is a tone filter 19 which feeds through a rectifier 22 and resistance 23 a relay 21 controlling a stepping switch 26. In the non-receiving position, a battery 45 energizes coils 46 and 48 through circuit 43 and valve 44. This releases switch 26 so that contact arm 35 is moved by spring 41 to engage contact 36 and bell 50 is de-energized by coil 48. When a carrier is locked in, a voltage from the A.V.C. line blocks valve 44 and so de-energizes coils 46 and 48 to energize bell 50. This is followed by the transmission of a signal characteristic of the station calling, such as one, three or four dots in a low tone which is selected by filter 19. This steps round switch 26 to the appropriate contact 37 ... 40 to light one of the lamps A, C or D (the receiver being at station B) and so indicate which station is calling. When the carrier stops, valve 44 is un-blocked and the apparatus returns to the original position. A modification is described for a system enabling a central station to call a group of stations or any one of a group. In this case the audio output is fed direct to contact arm 35 and a pair of phones is connected to two contacts, one say 39 characteristic of the group and another say 37 peculiar to the receiver, then if the code of one dot is transmitted only the one receiver gets the call while a signal of three dots calls all the stations in a group. Specification 549,769 also is referred to.

Abstract: 1,159,282. Continuously winding bobbins, tension arrangement. ELITEX - ZAVODY TEXTILNIHO STROJIRENSTVI, GENERALNI REDITELSTVI. 20 Jan., 1967, No. 3130/67. Headings DID and D1J. Filament 8 is continuously wound alternately onto two-coaxial roller-driver bobbins 31, 37 and during transfer of winding to the empty bobbin the speed of feed of the filament 8 is reduced to that of the peripheral speed of the bobbin on which the winding has been formed (bobbin 37 as shown in Fig. 2). As shown, the speed of feed of the filament is reduced by moving the filament from the larger diameter 2 or 4 to the smaller diameter 33 or 34 of the feed roll 3 or 5 using guide 1 the filament 8 is thereby kept under tension during transfer of the winding. During winding the filament 8 is returned to the larger diameters of the feed rolls, the filament 8 is transferred between the bobbins by pushing the filament out of the transverse guide 7 or 32 with batten 30, moving the filament with pneumatic piston and cylinder 19, 20 and moving batten 30 back and away from the guide 7 or 32 so that the filament automatically feeds itself into the guide.

Filed: 1973-01-22
Abstract: 1436181 Antibiotic sensitivity testing PFIZER Inc 22 Jan 1973 [18 Aug 1972] 3263/73 Heading G1B The relative effects of a number of different antibiotics in inhibiting the growth of bacteria in a liquid sample is determined by a method comprising dividing the initial sample into a number of samples S c , S 1  to S 12 , simultaneously introducing into the samples one each of the antibiotics, added for example from respective dispensers 39 on manual operation of lever (51), maintaining however one of the samples S c  free of antibiotic for use as a control sample, incubating the samples to develop differences in the growth rate, agitating the incubated samples to obtain a uniform suspension of the bacteria in each of them, for example by placing each set of samples in its cuvette (12) on to shelves in an incubator in which the shelves can be rotated Fig. 22, (not shown), successively photometrically reading a light scattering characteristic in a limited portion of each suspension, completing the reading for all the samples within a brief time interval so that the effects of differences in the growth rates are substantially nullified, and computing for each of the samples a function of the reading obtained for the sample and of that for the control sample. For the division of the initial sample, an aliquot of the initial sample is placed in a screw threaded tube 78 which contains a growth medium, and the tube 78 is screwed in an upright position into port P of cuvette 12 Fig. 9. Rotation of the assembly allows flow of the medium first into a reservoir R then in equal amounts into the "testing lobes" 15. The cuvette in upright position is then slid beneath the antibiotic disc dispenser assembly Fig. 14, (not shown) for introduction of the discs into upper "distribution lobes" 29 where the discs are immersed in the liquid media. After incubation, the cuvettes are mounted in turn in carriage 46 Fig. 27 and moved to bring one sample at a time into line with the light source 82.

Title: Improvements in or relating to electronic adding circuits
Inventor: TOWNSEND RALPH
IPC: G06F7/50
Filed: 1953-02-06
Abstract: 738,314. Digital electric calculating-apparatus. BRITISH TABULATING MACHINE CO., Ltd. Oct. 16, 1953 [Feb. 6, 1953], No. 3415/53. Class 106 (1). Electronic apparatus for adding two serial trains of binary coded pulse groups comprises a first adding means for producing an uncorrected sum pulse train, a carry storage device for the first adding means, comparing means for determining whether or not each sum pulse group is equal to or greater than the radix of notation of the group, means controlled jointly by the comparing means and the carry storage device for generating a " filler " digit pulse group, a second adding means for adding the " filler " digit pulse groups to the uncorrected sum pulse train, and means for setting the carry storage device each time a " filler " digit pulse group is generated. The embodiment shown is a modification of those described in Specification 678,427 and operates on decimal numbers of which each digit is represented by a group of four pulse periods corresponding to 1, 2, 4, 8, the " filler " digit being 6. The numbers, from shifting register 1 and on line 3 respectively, are applied in serial form to first binary adder 2 and the uncorrected sum train is applied through one-pulse-group-delay circuit 5 to second binary adder 6, the adders being, e.g., similar to that described in Specification 738,269. This sum train is applied also to a comparing means, similar to that described in Specification 738,294, comprising a shift circuit 19, coincidence circuit 7 and a comparison trigger 18 which, if a sum pulse group is greater than nine represented by a pulse train applied over line 10, will be set to a " 1 " condition. If either the carry trigger 4 associated with adder 2 or the trigger 18 are in the " 1 " condition, a gate 8 is open and allows an end-of-group pulse on line 15 to set a trigger 11 to the condition in which it opens gate 12 to allow a filler digit pulse group on line 16 to pass, via delay circuit 13, to the second adder 6; the pulse on line 15 also resets the carry trigger 17 associated with trigger 6, and the output pulse from gate 8 sets trigger 4 into the " 1 " condition (if not already set) for registering a carry between groups. If, however, triggers 4 and 18 are both in the " 0 " condition, a gate 9 is open to cause the pulse on line 15 to set trigger 11 to the gateclosing condition. Reference is made to the addition of numbers in non-decimal and mixed notations.
