Title: Improved cut-off and transfer mechanism chiefly designed for use on heading, upsetting and like machines
IPC: B23Q7/10
Filed: 1943-02-04
Abstract: 563,570. Shearing; forging. WILCOX, R. L., and WATERBURY FARREL FOUNDRY & MACHINE CO. Feb. 4, 1943, No. 1850. [Class 83 (iv)] In a machine for making articles from wire or rod, the wire is fed axially into a correspondingly shaped aperture between two shear blades which are then brought together to grip the wire and moved laterally to shear off a blank against the die through which it is fed. The wire A, Fig. 3, is fed through the stationary die 56 against a stop (not shown), whilst the aperture 57, Fig. 1, between the shear blades 16 is at the feeding position. The blades are mounted in slides 17, 18 which are slid positively in both directions by cams on the shaft 35, one - cam 44 acting on the slide 18 through a lever 45 and plunger 50 carrying an adjustable stud 52, and the other acting on the slide 17 through a lever 25 and a yielding link, springs such as 47 maintaining the linkages in contact with the cams. The cams are arranged so that during feeding of the wire the lever 25 recedes slightly from the slide 17, allowing a spring 23 to separate the shear blades, but when feed has ceased the slides are forced together to grip the wire in the aperture 57 and the slides then move bodily to the right in Fig. 1 to shear the wire against the die 56. The cut-off blank is then carried by the shear blades to the ejecting station, where the slide 17 engages an adjustable fixed stop 24 and the cam 44 allows the slide 18 to recede slightly to release the blank whilst it is pushed by a plunger 58, Fig. 3, into a notch 71 in a transfer arm 67 having a spring latch 68, Fig. 11. The arm 67 is adjustably carried by a lever 65 pivoted on the shaft 26 and connected by a link 76 to a rock-shaft 74. Cams 81, 83 angularly adjustable on the cam-shaft 35 engage a lever 88 held thereto by a spring 98 to oscillate the shaft 74 through a link 92 having a yielding connection 95. When dealing with long blanks such'as B, Fig. 3, the notch 71 is swung beyond the ejecting plunger 58 and waits there for the blank to be pushed through the aperture 57 in the shear blades, after which it snaps on the blank and then carries it to the die 12, Fig. 11, for the upsetting &c. operation. When dealing with short blanks, the upward swing of the lever 65 is limited by a lug 79 thereon engaging an adjustable stop 78, the notch 71 then being in line with the ejector plunger to receive the blank. The blank is located opposite the die 12 by a stop 77 engaging the lug 79. Shear blades and cutters; gauging-stops.-The operative parts of the shear blades have a thick portion 60, Fig. 7, so as to give ample support to the blank whilst it is being sheared from the wire, in order to produce ends which are square to the axis, and when the length of the blanks is less than the thickness of the portion 60, the gauging stop has a narrow blade projecting into a slot 63 in each shear blade.

Abstract: The invention comprises N-propyl-a  : b -dimethylsuccinimide and a process for its preparation by reacting a  : b -dimethylsuccinic acid or a  : b -dimethylsuccinic anhydride with n-propylamine and heating the intermediate product so produced to a temperature between 100 DEG and 350 DEG  C.  The nature of the intermediate product depends upon the materials employed and the quantities taken; thus using a  : b -dimethyl succinic anhydride either the halfamide or its n-propylamine salt is obtained, whereas the corresponding acid yields its mono- or di-n-propylamine salt.  In examples: (1) racemic a  : b -dimethylsuccinic acid and aqueous n-propylamine are distilled to remove water, the residue heated to 200 DEG  C. extracted with ether and distilled in vacuo yielding N - propyl - a  : b  - dimethylsuccinimide; (2) a  : b -dimethylsuccinic anhydride and ethanolic n-propylamine are treated as in (1) to yield the same product.

Abstract: 1491471 Colour television; radar display DEFENCE SECRETARY OF STATE FOR 21 Jan 1975 [21 Jan 1974] 02764/74 Headings H4F and H4D [Also in Division G2] An electrically controllable colour filter including a liquid crystal cell with variable optical rotating power is disposed in front of a single hue CRT or electroluminescent display panel selectively receiving a number of different image signals and is controlled according to which of the signals is being displayed so that the respective images appear in different hues. The signals may be derived from a radar system and a computer for receipt at different selectable inputs, selection of the input being manual or automatic, e.g. controlled by the computer. The filter may be such that different regions can transmit different hues contemporaneously, e.g. a coincidence addressed X-Y matrix, the different signals being gated to different areas of the display. Alternatively the signals may be frame sequential television colour signals. In Fig. 4 a fixed striped filter 25 is provided between a CRT 23 and a liquid crystal filter 27, alternate stripes registering with alternate display lines. Fig. 5a shows the emission of the CRT, and Figs. 5b and 5c the transmission characteristic of the filter 27 in its two states. The stripes of filter 25 respectively select C 2  and C 3  when filter 27 is in its band reject state F 2 , and at least one set of stripes must also pass C 1  when the filter is in its band pass state F 1 . The signals for colours C 2  and C 3  carry information only on the appropriate set of alternate lines. The signal for C, may be similar, or present for all lines. In a modification filter 25 is replaced by a second liquid crystal filter with band pass/reject characteristics as in Figs 5b and 5c but operative, e.g. at C 3 .
