Title: Method of producing a glaze-like surface on stone and the like
IPC: C09D161/24
Filed: 1927-12-28
Abstract: 282,786. Stoll, K. Dec. 29, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Ornamenting.-A glaze-like surface is produced on stone, artificial stone, pottery, and like articles bv the application of a coating consisting wholly or principally of urea-formaldehyde resin, and in. a preferred form such a resin is employed together with one or more other resins such as phenol-formaldehyde resin. Two or three coats of the resin are applied, each coat being dried before a covering layer is added, and the coated article is heated for 3 to 5 hours. In one example, phenol-formaldehyde resin, dissolved in alcohol, and pigment such as zinc oxide, castor oil, and ammonium sulphate are added to a solution of urea-formaldehyde resin. The mixture is ground and dilute spirit added. In another example, concentrated urea-formaldehyde resin is added to wood spirit, amyl alcohol, ethylene chlorhydrin, titanium white &c., and castor oil.

Abstract: 1,236,557. Transistor gating circuits. SIEMENS A.G. 14 July, 1969 [15 July, 1968], No. 35304/69. Heading H3T. One transistor 4 of a complementary pair 4, 7 is arranged to gate an A.C. signal from an input 1 to an output 3 under the control of a signal applied at 1<SP>1</SP> to the base of the other transistor 7 whose emitter-collector path is connected in series with two resistors 51, 52 between supply lines, the junction of the resistors being connected to the base of T4 and the base of T7 being connected to the collector of T4. The transistors T4, T7 constitute a bistable in which T4 does not saturate when turned on. An input transformer 12 may feed several bi-stable gating circuits similar to T4, T7 either from the same or respective secondaries. The output of one or more of the bistable gating circuits is or are connected to the output 3 through an inverting amplifier 8 having negative feedback to the emitter of T4. Alternatively, the output may be taken from T4 emitter (Fig. 1, not shown), the resistor 55 also being omitted. A third transistor 74 having a fixed base bias 72, 73 and optionally receiving a pilot signal at 70 is connected across the collector and emitter of the transistor(s) 4, and is arranged to be conductive only if no transistor T4 is conducting, and not otherwise. Each transistor 4 may have an associated similar transistor (4<SP>1</SP>, Fig. 3, not shown) connected, in like fashion, to T7 and receiving the other part of a push-pull input A.C. signal from a centre tapped secondary 12, 12<SP>1</SP> of the input transformer. One or more such push-pull gating circuits drive an output circuit (9) in which respective common collector transistors (94, 94<SP>1</SP>) drive the centre tapped primary of an output transformer (96).
