Title: Transparent graft interpolymers and their production
IPC: C08F287/00
Filed: 1965-11-25
Abstract: A transparent graft interpolymer consists of from 4 to 20% by weight of a linear styrenebutadiene copolymer having a butadiene content of from 80 to 95% by weight, the remaining 96 to 80% comprising in parts by weight from 10 to 35 parts of an alpha-alkyl styrene and 90 to 65 parts of an alkyl methacrylate. The alkyl groups contain from 1 to 4 carbon atoms.  In certain embodiments, part of the alkyl methacrylate is replaced with acrylonitrile and/or methacrylic acid.  The graft polymers are produced by carrying out a bulk or solution prepolymerization with shearing agitation on the monomer-rubber mixture until a product containing from 10 to 40% by weight of solids is obtained and then polymerizing the resulting product to substantial completion in the absence of such agitation.  The dispersed rubber particles produced in the prepolymerization may range from 0.1 to 10 microns in size.  In the examples, the rubber is grafted with alphamethyl styrene and methyl methacrylate, together with acrylonitrile in one case, by a process comprising prepolymerization in bulk in the presence of t-butyl perbenzoate and/or di-t-butyl peroxide, followed by completion of polymerization in suspension in an aqueous medium containing hydroxyethyl cellulose.

Patent GB-509450-A (GB)
Abstract: 509,450. Transfer mechanism. KOOPERATIVA FORBUNDET, FORENING U.P.A. April 20, 1938, No. 11846. Convention date, April 21, 1937. [Class 106 (i)] In a transfer mechanism in which an actuator rack is moved relatively to an associated differential setting-member by a transfer driving-member when the latter co-operates with a guide member moved to effective position at transfer by the totaliser wheel of lower order, the actuator rack is positively locked to the differential member except during transfer. The invention is described as applied to the machine forming the subject-matter of Specification 509,441 wherein each actuator 17 is slidably mounted for one step of movement on an associated differential member 1 and is permanently connected through a wheel 21 to a pinion 22 that may be engaged alternatively with the associated wheel 27, 28 of either of two totalisers. The actuator is normally held in its uppermost position by a detent 35 pivoted to the differential and spring-urged counterclockwise to engage its shoulder 37 beneath a lug 38 on the actuator. At the beginning of an operation, a transfer driving-member 29, pivoted to a lever 33 and urged by a spring 49 against a rod 50 is moved upwards to maximum extent. The coupled differential and actuator now move idly upward until arrested by the depressed key, and return effectively to advance the engaged totaliser wheel. If transfer occurs, a cam 44 rigid with the totaliser wheel of lower order rocks a member 40 counterclockwise to interpose a guide surface 41 in the path of a stud 39 on the driving- member. As the driving-member returns at the end of the operation, it is cammed clockwise by the engagement of the stud 39 with the guide surface 41, whereby an offset portion 47 is caused to disable the detent 35 and by abutment with the lug 38 lowers the actuator to add an additional unit. At the beginning of the next operation, a stud 46 on the driving-member restores the actuator and the detent becomes effective to re-couple it to the differential.

Title: Methods of and apparatus for punching holes through or partly through blanks
Inventor: FUCHS FRANCIS JOSEPH JR
IPC: B26F1/26
Filed: 1969-10-17
Abstract: 1292057 Punching WESTERN ELECTRIC CO Inc 17 Oct 1969 [17 Oct 1968] 51026/69 Heading B3W A method of punching a hole through or partly through a blank 65 comprises positioning the blank against a die 60 having an aperture 62 and advancing a punch 72 into the blank whilst applying pressure to the blank around the punch through fluid 75. The fluid enlarges the hole as the punch progresses to prevent frictional drag of the blank on the punch and puts the material of the blank adjacent the punch in a tensional stress condition sufficient to propagate cracks formed in the blank by the punch. The punch is slidably mounted in a piston 70 in a pressure vessel 52. Seals 66, 77 and 81 are provided. In operation, bores 54, 56 are filled with fluid, the punch is advanced into contact with the blank and the piston 70 is advanced until the fluid is at a pressure predetermined within the optimum pressure range for the particular blank and the piston advanced or retracted to maintain the predetermined pressure. The punch 72 is then advanced to punch a hole in the blank, the fluid pressure in vessel 52 being relieved when the slug is ejected. In a second, two-punch, embodiment, Fig. 4, a fixed plate 123 closes the rear of the vessel 102, two punches 130, 131 are mounted on a ram 138 outside the vessel which comprises three aligned bores 109, 112, 106 and 117, 119, 115 respectively for each punch. Pressure fluid is supplied at 173 to the largest bore for punch 130 which is connnected at 171 to the largest bore for the other punch. Again the fluid pressure is increased after the punch has made light contact with the blank. In a further embodiment, Fig. 5, not shown, the two medium diameter bores (212), (219) are interconnected by a passage (271) to which pressure fluid is supplied. Each punch is housed entirely within the pressure vessel (200) and comprises a piston, a shank and a nose. The shanks fit closely in the bores (212), (219) and carry sealing rings which isolate a first chamber round the punch nose from an air filled bore (206), (215). A second fluid chamber is formed behind each piston. Since the punches are of different diameters and are not mounted on a common ram one hole is punched first and the seal of its associated first fluid chamber is momentarily broken. A seal ring (281) or (282) on the shank shoulder of the associated punch seals against the shoulder at the junction between the smallest and intermediate bores as the punch is advanced further. In a further embodiment (Fig. 6, not shown) the punch portions (333), (340) act as pistons to pressurize the fluid, the pressure level being controlled by spring-loaded check valves (373), (374).

Title: Transistor coupled logic circuit
IPC: H03K19/013
Filed: 1975-12-12
Abstract: 1525499 Transistor logic circuits TEXAS INSTRUMENTS Inc 12 Dec 1975 [23 Dec 1974] 51037/75 Heading H3T Saturation of the output transistor Q4 of a logic circuit is prevented by connecting a second emitter of the driver transistor Q3 to the collector of Q4. Since Q6 is turned off when Q4 is on, any tendency for Q4 to saturate causes its collector to draw more current through one emitter of Q3 thereby reducing the base drive to Q4 through the other emitter. As shown, a NAND gate has inputs Ip to the bases of PNP transistors Q1A Q1B so that when both inputs are positive, Q1A and Q1B turn off thereby turning emitter follower Q2 and double emitter transistor Q3 on. Q3 acts as a phase splitter, turning on Q4 and turning off the Darlington pair Q7 and Q6. The output OP is therefore held at the logic zero level equal to the base emitter drop V BE  of Q4. If either input is low, Q4 is turned off and Q6 is turned on, diodes D2 and D3 and the base-emitter junctions of Q6, Q7 and Q8 ensuring that the output OP is at the logical one level of 3V BE  Schottky diodes D1, D1 and D4 prevent transistors Q1A, Q1B and Q3 saturating. Q5 and Q7 are provided internally with similar diodes between collector and base. Diodes D2 and D3 may be diode connected transistors.
