Abstract: 1,160,209. Digital shifters. INTERNATIONAL BUSINESS MACHINES CORP. 25 June, 1968 [14 July, 1967], No. 30172/68. Heading G4A. A digital shifter comprises a plurality of logic stages connected in series which, in response to a command indicating the direction and amount of shift, shift an input word the command amount in a first direction when the command direction is the first direction and ring shift it the twos-complement of the command amount in the first direction when the command direction is the other direction, blocking control means being provided for blocking from appearing at the shifter output all bits of the input word which are shifted out in the first case and all those not shifted out in the second case. As described, a 64-bit word is passed through three stages of gating logic in turn which ring-shift it by 0, 16, 32 or 48; 0, 4, 8 or 12; 0, 1, 2 or 3 bit positions to the left respectively, the second stage performing the blocking referred to. It is mentioned that the blocking could be inhibited so that the final result would be a ring shift.

Abstract: In a method of mixing and dispensing liquid components to form a foamed (especially polyurethane) plastic, they are turbulently mixed by compressed air in a primary mixing chamber and then conveyed through an elongated secondary mixing chamber in which further mixing and reaction take place.  In an example a partial pre-polymer having an -NCO to -OH ratio of 7,2:1 was made by heating together for 1 hour at 110 DEG C. 80 parts by weight of an 80:20 mixture of 2,4 and 2,6 tolylene di-isocyanate and 20 parts of a liquid polyester resin having an OH number of 360, an acid number of 1 and a water content of 0,1%.  A mixture was also made of 91,8 parts by weight of the same polyester, 2 parts of N-methyl morpholene, 5,4 parts water and 0,8 parts sorbitan monopalmitate.  100 parts of the partial pre-polymer and 60 parts of the polyester/N-methyl morpholene mixture were supplied to the apparatus described (see Group II) at an aggregate rate of flow of 5 lb. per minute by air at 50 p.s.i. and the mixed material was discharged into a mould as a milky material in the pre-foaming stage.  The air pressure is limited to a range 10-70 p.s.i., which is less than that required to atomize the components.ALSO:In a method of mixing and dispensing liquid components to form a foamed (especially polyurethane) plastic, they are turbulently mixed by compressed air in a primary mixing chamber and then conveyed through an elongated secondary mixing chamber in which further mixing and reaction take place.

Figs. 1 and 2 show a guard for a right-angle joint in a bus-bar and formed from a material known under the registered Trade Mark "Pernax." Two sheets 1, 2 of this material are moulded under heat over an elbow-shaped former.and formed along the cranked edges with flanges 3 perforated to receive lacing 4 which is preferably a thin cord coated with " Pernax." Fig. 3 shows a guard for aT-joint formed by moulding a cruciform blank over a T-shaped former having limbs of circular section. The guard is formed with perforated flanges 3 adapted to receive lacing 4. The ends of the limbs in both constructions are tapered to grip the bus-bars.

[Class 39 (i).] A transparent lightsensitive layer is formed on a foundation member and is transferred therefrom to the wall of the envelope. A copper washer 4 is silver plated and is then oxidized by passing a high-frequency or direct - current discharge between the anode 5 and the washer 4 in oxygen at 100 microns. Capsules 7 are heated to liberate calsium and to form the layer on the washer 4, and the bulb is baked at 300‹ C. and evacuated by the process described in Specification 303,476, [Class 39 (i), Electric lamps, Arc &c.]. The light-sensitive material is transferred to the envelope by cathodic sputtering, an alternating or direct current discharge being passed in argon at 100 microns. The thickness of the layer is determined by noting the degree of discolouration of the bulb or by measuring the resistance between a pair of leading-in wires 9 which contact with the inner surface of the envelope. The washer 4 is subsequently connected to the anode. A glass sleeve 8 protects the conducting support 6 for the washer 4. Specifications 333,548, [Class 39 (i), Electric lamps, Arc &c.], 360,416, and 375,614 also are referred to.

A D.C. power supply arrangement for arcwelding apparatus of the shielded consumable electrode type comprises a three-phase transformer T1, a saturable reactor NR and a rectifier system RF, the reactor NR having two control coils Nb, Ni of opposite bias, that of the coil Nb being adjustable to a predetermined value by a resistor R4 and that of the coil Ni increasing with increase in welding current, Fig. 5 (not shown), due to feedback through a current transformer CT and rectifier bridge Sel. This feedback circuit includes a capacitor C and resistor R3 which ensure stability of the arc by absorbing energy fluctuations produced by sudden large changes in welding current. Various combinations of resistor, capacitor and inductance may be used in the feedback circuit to produce a stable arc, a theoretical discussion being given of such action in relation to the operating characteristics of the circuit, Figs. 6, 7 and 8 (not shown). Variation of bias in the coils Nb, Ni is discussed for variation in the voltage-current gradient of the output characteristic and variation in voltage with a fixed gradient.
