Title: Apparatus for and method of cleaning tape
IPC: G03D15/00
Filed: 1964-10-16
Abstract: 1,016,996. Cleaning magnetic tapes. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 16, 1964 [Oct. 18, 1963], No. 42365/64. Heading G5R. [Also in Divisions G2 and H1] A magnetic or other information bearing tape 12 is cleaned by passing it between a fixed tungsten carbide blade 40 and a moving tungsten carbide blade 42 held by a spring. Ceramic discs 50 and 52 (the latter not being visible in the Figures) are on a common shaft and press on the edges of the tape to remove particles thereon. Aligned notches 54 in the discs and spaces in front of the blades provide a channel for the gas stream. The cleaning apparatus is incorporated in testing equipment for newly manufactured tape, and may include a magnetic sensing head which, by means unspecified, senses particles which are not scraped off and reverses the tape for a second pass through the scraper. If after a preset number of passes a particle is not cleared, the tape is stopped for inspection. A further cleaning section (Figs. 6 to 10, not shown) uses two gas streams to vibrate the tape at 13 kc/s. to remove particles held by electrostatic attraction.

Title: Range-limited radar system
Inventor: ERST STEPHEN J
IPC: G01S13/34
Filed: 1960-12-09
Abstract: 946,869. Radar. INTERNATIONAL TELEPHONE & TELEGRAPH CORPORATION. Dec. 9, 1960, No. 42564/60. Heading H4D. In a " range-limited " radar system, i.e. a system which provides an output signal only when the target is at a predetermined range, the transmitted beam consists of a carrier frequency source 4 (Fig. 1) frequency modulated by two separate sinusoidal waves of frequency #1 and f2. A portion of this transmitted energy is combined with the energy received from the target in a mixer 6, the output from which is supplied to a receiver 8 including an I.F. circuit and tuned to the third harmonic of the modulating frequency #1 and a detector 10 from which the output signal is derived. The Specification includes a mathematical analysis of the system and shows that by the use of two modulating sources 2, 3 of suitable frequencies and amplitudes, the production of unwanted range response signals which occur in known systems utilizing a single modulating frequency is reduced, e.g. the curve 12 (Fig. 2) which has a desired first peak 13 also has an undesired second peak 14 (produced by rectification of the portion 14a) exceeding the threshold level 16, to signals above which equipment connected to terminal 11 responds. In the present invention the use of two modulating frequencies produces a resultant signal which has a desired peak 19, 20 above the threshold level 16 whilst the undesired range responses produce peaks such as 21, 22 which are below level 16. A particular example for a range of 1200 feet is referred to in which the undesired second peak was adequately reduced by utilizing frequencies of 0.09 mc/s. and 0.02 mc/s. for f1 and #2 respectively.

In a preferred embodiment, Fig. 2, the guard comprises a plate 40 having a plurality of petals 42 formed by slits 44 and made of a resilient and somewhat heat resistant sheet metal. The guard 40 is fastened to the housing 16 by a rivet 46 and a bracing hoop 48, made of aluminium or plastics, is broken by the gas pressure so that the petals 42 can straighten, Fig. 3 (not shown), to prevent the bag, on subsequent deflation, and the driver, from contacting the heated housing 16. In a modification, a plurality of guard plates 50, 5a, Figs. 5, 6, are secured to the housing 16 and are arranged to flap away from the outlets 20 when gas is discharged. In a further embodiment, Fig. 9, the guard 7 has slits or notches forming petals 64 which fold outwardly on gas discharge. An adhesive may be applied to the slits. A heat insulating material (74), Fig. 7 (not shown), is provided between the housing 16b and the guard. In a similar arrangement Fig. 13 (not shown), a guard (80) has axial slits or notches (82) which allow the wall (80a) to expand outwardly when generator 14 is actuated.

Abstract: 1448147 Hydrostatic transmission control RAYMOND CORP 18 Sept 1973 [23 Feb 1973] 43676/73 Heading F2W [Also in Divisions F1 and B8] In an hydraulic system wherein the output of a pump 17 is delivered through a line 18 to an hydraulic ram 20 or to a fixed or variable displacement motor and a manual control lever 10 operates via a telemotor system 12-14 to control the pump output, a piston and cylinder device 24, 25 detects the load-dependent pressure in the line 18 and adjusts the telemotor system thereby to effect a change in the pump output without necessarily changing the position of the lever 10. The pump 17 is either of variable-displacement or of constant displacement but variable speed. The telemotor system comprises a master cylinder 12, 13 connected by a line 14 to a slave cylinder 15, 16 for adjusting the pump displacement. The pressure occurring in the line 18 and the rate of a spring 26, which rate may be fixed or variable, Figs. 1a, 1b, 1c (not shown), determines the distance moved by the piston 25. This piston movement causes corresponding movement of a coupled piston 27 which adjusts the telemotor system by altering the volume of a cylinder space 28 connected by a line 14a to the line 14. An alternative construction of the piston and cylinder device 24, 25 is described, Fig. 2 (not shown).

The chamber is provided with a fluid outlet, e.g. bleeder valve 6 and a spindle 1 having cutting means, drill 2 and cutter 3, is supported for rotation and axial sliding movement in the chamber. The spindle is slidable with respect to two coaxial gear-wheels 15, 16 and rotates with the first wheel 15.
