Title: Flight path angle computer
IPC: G09B9/16
Filed: 1960-08-05
Abstract: 957,179. Measuring electrically. SPERRY RAND CORPORATION. Aug. 5, 1960 [Sept. 23, 1959],No. 27216/60. Heading G1N. [Also in Division G3] In a system for computing aircraft flight path angle, acceleration of the aircraft along its yaw axis is divided by airspeed and the result integrated to give an output representative of flight path angle, long term errors in which are corrected by feeding back any difference between a function of the above-mentioned output and the output of an alternative measuring device not subject to long term errors. In Fig. 1, a signal from an accelerometer 10 responsive to acceleration along the yaw axis of an aircraft but biased to eliminate the effect of the gravitational acceleration, is applied through an amplifier 12 to a unit 14 in which it is divided by a signal representing airspeed derived from a device 16. The output of unit 14, representing the rate at which the flight path elevation angle is changing, is integrated at 18 to produce an output signal y representing flight path angle, which may be used for indicating or automatically controlling flight path angle. The sine of this signal derived by a unit 20 and multiplied by the airspeed signal in a unit 22 represents a rate of climb signal with short term accuracy which is compared in a unit 26 with a rate of climb signal having long term accuracy derived from a barometic device 24. Any difference is applied to amplifier 12 to add long term accuracy to the output signal. When pitch and roll are appreciable, a gyro-vertical (not shown) applies to amplifier 12 a signal which is a cosine function of pitch and roll and a function of gravitational acceleration.

Title: Improvements in method of and means for making multifocal lenses
IPC: C03B23/22
Filed: 1934-09-25
Abstract: 428,270. Glass manufacture. BAUSCH & LOMB OPTICAL CO., 635, St. Paul Street, Rochester, U.S.A. Sept. 25, 1934, No. 27473. Convention date, May 2. [Class 56] A method of making multifocal spectacle lenses consists in forming a composite button by fusing together two or more pieces of glass of different refractive indices, and then fusing the composite button in a countersink in a blank of glass while applying pressure to the top of the button. The composite button may be formed by fusing two pieces of glass 27, 28 edge to edge, or by fusing one piece of glass in a recess which passes partly or wholly through the other piece. The button so formed is ground on one side to the required curvature and polished, and is then placed in a recess formed in a member 36 made of refractory material which does not adhere to softened glass. The button fits closely in the recess, and the wall 38 of the recess extends around the button. The button is then placed in a ground and polished countersink formed in a lens blank 34, a small pin 40 being placed under one edge of the button, as usual. The assembly is then placed in a furnace and heated until the button fuses into the countersink in the known manner. The refractory member 36 shields the button from direct heat and prevents the glass from becoming softened too soon. It also constrains the parts of the button and prevents them from spreading and becoming distorted during fusing. The weight of the member also presses the button into intimate contact with the surface of the countersink.

Title: Apparatus for supplying cold water to the input side of hot water pumping plant
IPC: F04D9/00
Filed: 1960-08-10
Abstract: 890,773. Centrifugal pumps. SULZER FRERES S.A. Aug. 10, 1960 [Aug. 22, 1959], No. 27767/60. Class 110 (1). [Also in Groups XIII and XXIX] In a hot water pumping plant, evaporation of water in the pump due to drop in pressure at the input side of the plant is prevented by supplying cold water to the input side through a valve controlled by a signal initiated by the rate of change of the pressure with respect to time. In the plant shown, hot water is stored under steam pressure in a tank 1, condensate being supplied through a pipe 10. A pump 3 delivers the hot water to a steam generator (not shown). Any fall in pressure in the tank 1 is communicated rapidly through a pipe 11 to the right-hand side of a diaphragm 12, but a throttle 7<SP>1</SP> and a vessel V delay the application of the pressure fall to the left-hand side of the diaphragm. The resultant temporary inequilibrium between the pressures on the two sides of the diaphragm 12 causes it to open a valve 5 to admit cold water from a pipe 16 to the inlet pipe 2 of the pump 3 to prevent evaporation of water in the pump. The cold water is admitted to the pipe 2 through four branch pipes 6 each containing a throttle 81, the throttles being individually adjustable to vary the quantity of cold water supplied and its distribution over the length of the pipe 2. The sensitivity of the control can be varied by adjustment of the throttle 7<SP>1</SP>. The throttles 7<SP>1</SP>, 8<SP>1</SP> are adjusted in dependence on the load on the steam generator by means of cams 22, 24 carried by a shaft 19 connected through linkage 21 to means (not shown) for controlling the load on the steam generator. In addition, the control of cold water flow provided by the valve 5 is modified by a valve 44 provided upstream of the valve 5 and operated by a piston 37. The piston 37 is subjected, through a pipe 36, to the pressure downstream of the valve 44 and to the opposing force of a spring 41, the spring force being adjusted by means of a movable abutment 40 controlled by a cam 32. In a modification, the valve 44 and the means for automatic adjustment of the throttles 7<SP>1</SP>, 81 are omitted. It is stated to be known to control the cold water supply by means of a valve which is responsive to the temperature and pressure of the hot water.

Title: Radio wave transmission and reception systems
IPC: H04B7/00
Filed: 1935-10-10
Abstract: 467,163. Wireless signalling. HILLS, J. L. Oct. 10, 1935, Nos. 27991/35 and 23338/36. [Class 40 (v)] A carrier wave is transmitted the frequency of which is continuously varied over the whole or part of a predetermined band, a supersonic heterodyne frequency being produced at the receiver by a local oscillator the frequency of which is also varied continuously, but differently over the same band. In the intercommunication system described, at each station the transmitter itself is used as the source of local oscillations for the receiver and the frequency bands of the various transmitters become segregated by automatically varying the direction of transmitter frequency variation when an incoming signal approaches the frequency of the transmitted signal. Alternatively a muting circuit may become operative when an audible intermediate frequency is produced. As shown the frequency of a transmitter T is cyclically varied by the rotation of the movable plate of a variable condenser 1 at about five to seven revolutions per second by a motor 2 through a gearbox 3. The receiver comprises an aerial 6, and a frequency changer D1 fed by incoming signals and signals from the adjacent transmitting aerial 5. The output from the following aperiodic I.F. amplifier, IFA1, is applied through switch S1 to the second detector D2 feeding a telephone instrument P and if desired a tuned relay system C1, R1 actuating apparatus B or a rectifier 7 and meter Ma. A muting device M may be associated with the detector D2 coming into operation when the intermediate frequency is reduced to 4000 or 5000 cycles. Alternatively the direction of rotation of the condenser 1 may be reversed when the intermediate frequency reaches this value by means of a tuned circuit C2 operating a relay R2 acting on the gearbox 3. A single station may be selected by connecting the detector D2 through switch S1 to an I.F. amplifier IFA2 which has a tuning control 10 and a selectivity control 11. For direction finding a rotatable loop aerial 6a feeding a frequency changer D1a and IF amplifier IFA3 is provided its output being combined in opposite phase with that from the aerial 6 by moving the switch S1 to the contact 15. According to the first Provisional Specification the carrier frequency variations may be dependent upon temperature, pressure, or other physical variations.

Title: Automatic multistage immersion and/or surface treatment transfer apparatus
Inventor: SMITH FREDERICK LEWIS
IPC: G03D3/10
Filed: 1956-09-13
Abstract: 837,009. Automatic photographic processing apparatus. RELY-A-BELL BURGLAR & FIRE ALARM CO. Ltd. April 10, 1957 [Sept. 13, 1956], No. 28075/56. Class 98(2) In apparatus in which a series of articles are treated in several liquid baths in succession, the articles are suspended from arms which extend radially from, and are pivoted for up and down motion to, a rotatable turntable which is movable stepwise about a vertical axis and a face cam moves a co-axially rotatable platform vertically, thus carrying members on the platform into engagement with the arms to lift them and at the same time coupling the platform for a step-wise rotational movement with the turntable to move the raised arms over the end walls of the baths and an equal and opposite step-wise rotation of the platform is effected after it has been returned to lower the arms and uncouple itself from the turntable. In an automatic dental X-ray film processing machine radial arms 5 carrying the X-ray films are raised by rollers 29 carried by platform 27 as cam roller 39 rides up continuously rotating cam profile 55, the pressure of cam 55 on the roller 39. ensuring engagement of arm 58 with stop 59. Those immersed films which are adjacent the end walls of part annular tanks are thus withdrawn from the tanks. Bars 44 and plate 45 are also carried upwardly and one of the former engages a notch of notched disc 25 which is rotatably fast with arms 5 so that on pin 56 contacting member 57 both platform 27 and arms 5 are rotated until arm 58 contacts stop 60. Thereafter roller 39 descends from profile 55 and the transferred films are immersed in the next tank. Locking tooth 48 is no longer retained by cam 52 but falls into the next notch in disc 25 under spring 49. During the initial rising movement of platform 27, the platform is returned by the pressure of cam 55 to its original position but arms 5 do not move as disc 25 moves in gap 47. Rollers 29 are thus ready, when next actuated, to raise the arms which occupy the positions of those previously raised. The temperature of developing and fixing tanks may be thermostatically controlled and washing after development may be effected by liquid jets and after fixing by successive baths. A drying zone in which warm air is blown upwardly may also be provided. According to the Provisional Specification, the fans may be automatically switched off when no films are passing through the drying zone. In another form, the vertical motions of platform 27 are carried out in reverse and the platform co-operates with parts 9 of arms 5. Among other minor differences cam 52 is used to effect the return movement of platform 27.
