Title: Improved means for observing and taking average readings in sextants and other instruments
IPC: G01C21/02
Filed: 1941-04-04
Abstract: 590,164. Integrating mechanism. TWINEY. F. J., and THOMAS, I. L. April 4, 1941, No. 4490. [Class 106 (iv)] The mean value of a time integral, such as the average of a predetermined number of readings of a sextant or other measuring instrument, is determined by a counter adapted to be driven automatically for a portion of each measurement period, which portion is a measure of the instantaneous value of the variable quantity. As applied to a sextant for obtaining the altitude of a star, the mirror of the instrument controls a shaft 11 which drives a wheel 10 carrying an arm 8, the movement being such that the angular distance between the arm 8 and a fixed arm 9 is a measure of the observed altitude. The arms 8 and 9 co-operate with a trip mechanism 5 in such a manner as to put a pawl 4 into engagement with a ratchet-wheel 6 and drive it through the set angular distance. The pawl 4 is carried by a spindle 3 on an arm 2 secured to a constant speed shaft 1 driven by clockwork or an 'electric motor. The ratchet-wheel 6 is connected to a counter 7 through a 60 : 1 reduction gearing so that after sixty revolutions of the arm 2 the reading on the counter will indicate the mean value of the sixty readings. The shaft 1 is rotated once in two seconds and is stopped by a rod 14 displaced by a cam 13 operated by gearing 12. The rod 14 has associated therewith a screen 15 to obscure the line of vision. A counter to indicate the revolutions of the shaft 1 and a stop trigger may be provided for use in interrupted observations.

Abstract: 456,646. Cooling buildings. MORRISON, W. L., 650, Northmoor Road, Lake Forest, Illinois, U.S.A. Feb. 12, 1935, No. 4494. Convention date, March 5, 1934. [Class 29] An air-cooling device for a room comprises a compartment 3 open at the top and formed with heat insulating walls, means for cooling air being provided at the top of the compartment so that warm air in the compartment is displaced by the descending cold air and flows out into the surrounding uncooled space in the room. The occupant of the room may thus sit in the compartment and be maintained in a cool atmosphere without the necessity of cooling the whole room. The cooling means may comprise a refrigerating machine 12 having an evaporator in the form of a finned pipe 10 extending around the upper edge of the compartment. The evaporator may also extend in serpentine fashion across the open top of the compartment. Troughs are provided directly below the evaporator pipes to prevent condensed moisture falling into the compartment. In the case of a bedroom the bed may be placed in such a compartment.

Abstract: 1502363 Data transmission INTERNATIONAL BUSINESS MACHINES CORP 5 Feb 1975 [12 Feb 1974] 4875/75 Addition to 1337056 Heading H4P A data transmission system of the type disclosed in Specification 1,337,056, in which the transmitted signals are comprised of combinations of signal elements which have to be conventionally demodulated to give data recovery, is modified by defining the signal elements less restrictively and by providing a receiver which samples the undemodulated transmitted signal at successive instants and which analyses the samples to determine phase, amplitude, or phase and amplitude of each signal element in the transmitted signal, depending on whether the signal elements are phase, amplitude, or phase and amplitude modulated in representing the input data. As shown, a transmitter for differential phase modulation comprises a circuit 45, Fig. 5, receiving data and forming information elements (one information element may be equivalent to several binary elements) which are delivered to 46 which determines components Ak(i) and #k(i) (defined in the Specification) which also receives delayed memorized element #k(i-1) from read only memory 47 which contains k coded words for k possible values corresponding to information elements corresponding to the useful part of a signal element; circuit 48 determines appropriate functions from such stored coded words, and also controls addressing of memory 47. Circuits 49 regroup the signal elements leaving 47, the elements being summed at d/a decoder 50 which delivers the summed signal in its analogue form through a filter which eliminates secondary spectra of the transmitted signal. At the receiver Fig. 6, which may be of the type described in Specification 1,387,078, incoming signals are supplied over a Hilbert transform device 20 and sampling switches Swl, Sw2 to capacitors 22, 25 which temporarily hold the samples for application to a/d converters 26, 27 addressing read only memories 30, 31 the outputs from which are added at 34 whose output addresses memory 35 to produce an arctangent output to circuit 36 which delivers value #k(1) to detector 41 which regenerates the information element in response to a direct input from 36 and an indirect input of Ak(i) produced from memory 38, subtractor 39 and further memory 40. If the transmission channel produces constant phase shift distortion this may be corrected by conventional circuits in an additional device in line 37, e.g. such as is described in Specification 1,409,932.
