Filed: 1964-09-15
Abstract: 1,116,625. Knitting-machimes. BENTLEY ENGINEERING CO. Ltd. 12 Aug., 1965 [15 Sept., 1964], No. 37570/64. Heading DIC. [Also in Division F2] The quadrant gear 1, Fig. 1 is oscillated by cams 5a, 5b which are mounted on a shaft 6 and coupled thereto and driven thereby only during the period in which reciprocatory knitting is performed. During continuous rotary knitting the connection between the shaft 6 and the cams 5a, 5b is broken and the quadrant gear remains stationary. Secured to the continuously driven shaft 6 is collar 9 having a groove 9a, Fig. 2, in which a latch member 12 can engage. The member 12 is pivoted on a member 5c integral with the cams 5a, 5b, so that when the latch member 12 is engaged with the collar 9 a drive connection is made between the shaft 6 and the cams. The latch member, opposite the collar engaging end, supports a rod 13, which projects through slots in the cams and engages in an inclined slot 15 in a component 16, Fig. 3, freely mounted on the hub 5 of the cams. Pivoted movement of the component 16 causes it to lift or lower the rod 13 as it rides up or down the slot 15 and bring the opposite end out of and into engagement with the collar 9. Consequently, by the provision of an arm 24a pivotably mounted on the outside of the frame 8 and selectively operated from a control drum on the machine it can be caused to engage or disengage the component 16 to cause its movement or permit its return movement by a spring 18 whereby the latch member 12 disengages or engages the collar 9 and effects the disengagement or engagement of the drive to the cams.

Abstract: 524,442. Fused silica. BURGESS, A. F. (Vereinigte Gluhlampen und Elektrizitats Akt.- Ges). Dec. 29, 1938, No. 37738. [Class 56] A process for obtaining transparent vitreous quartz consists in fusing silica acid which has been precipitated from solution. The wet precipitated material is pressed into pills and is heated in vacuo to a temperature not exceeding 500‹C. to allow moisture to escape. The temperature is then raised to 1000‹C. when the material commences to shrink and sinter, and is further raised to 1600-1900‹C. to fuse the material. Fusion may be accomplished also in an atmosphere, such as helium, to which the silica is permeable in a heated state.

Filed: 1960-11-16
Abstract: 960,829. Frequency sweep receivers. RAYTHEON CO. Nov. 16, 1960, No. 39433/60. Heading H3Q. In a circuit for detecting the presence of a signal in a high noise background at the output of a wide band receiver, the receiver output is mixed with a signal from a local oscillator which is swept through a frequency band such that if a signal is present it produces a product, frequency modulated at the sweep frequency, in a narrow band I.F. amp. connected to the mixer output. Since noise is not coherent the only F.M. signal present in the channel is that due to an incoming signal. The F.M. signal is amplified and applied to a discriminator which develops an output signal at the local oscillator modulation frequency and proportional in amplitude to the level of the input signal. The output of broad band receiver 13 is applied to mixer 19 with the output of a local oscillator 21 which is swept in frequency by a low frequency oscillator 30 whose output signal is applied to a reactance valve 25 connected across the oscillator tuned circuit. When a signal is present at the output of the receiver a F.M. signal is developed in a narrow band I.F. channel 23 and this produces an output signal from discriminator 31. This signal may be used directly for indicating the presence of a received signal or applied with an output from oscillator 30 to a phase comparator 32 which develops a D.C. output signal when a received signal is present.
