Patent GB-922863-A (GB)
Title: Improvements in or relating to electrical phase detectors
Inventor: YOUNG HUGH
IPC: H03K5/26
Filed: 1960-07-28
Abstract: 922,863. Phase-sensitive circuits. GENERAL ELECTRIC CO. Ltd. July 28, 1961 [July 28, 1960], No. 26382/60. Class 37. The phase detector indicates the phase relationship between two A.C. signals by means of the state of a bi-stable circuit and, in the particular embodiment, whether an input signal at 1 and a reference signal at 17 are in phase or antiphase. The input signal is converted into a pulse train by an amplifier limiter 3, 4 and is then differentiated by 5, 6 and applied to the bases of transistors 7, 8. The emitters of these transistors are connected to opposite ends of the secondary 9 of transformer 10. The operation of the circuit is as follows. During the " positive " half-cycle of the reference signal the emitters of transistors 7, 8 will be negative and positive respectively with respect to tap 12 while during the " negative" half-cycle they will be positive and negative respectively. If the input signal is " in phase " with the reference signal the negative-going pulses derived from the input will be applied to the bases of transistors 7, 8 during the negative half-cycles of the reference signal so that transistor 7 conducts while transistor 8 is blocked so that a positive pulse will be applied to the base of a transistor 18 forming part of a bi-stable circuit 20, thus either blocking the transistor 18 or maintaining it in a blocked condition, and thus in the former case causing transistor 19 to conduct and operate relay 21 so that a potential appears at 24, or in the later case maintaining relay 21 operated. During the positive half-cycle of the reference signal there will be no output from either transistor 7 or 8 due to the positive input pulse applied to their bases. If the input signal is in antiphase with the reference signal, the positive and negative pulses across resistor 6 will be applied to transistors 7, 8 during the negative and positive half-cycles of the reference signal respectively thus causing transistor 18 to conduring during positive half-cycles of the reference so causing relay to open to remain open and no voltage to appear at terminal 24. Transistors 7, 8 will both be blocked during negative half-cycles of the reference voltage. The operation of the phase detector can be stopped by opening switch 15. A system using such a phase detector for use with a positive encoder as in Specification 863,027 is described (Fig. 2, not shown).

Abstract: 189,925. Bennett, C. H. Oct. 6, 1921. Clinometers.-The pendulum A of a gradient meter for a vehicle is mounted on a knife edge member R. The knife edges rest on surfaces T of glass or other hard material carried by a casing B secured to an enclosing cylinder F and the casing or the cylinder may be filled with a damping liquid. To prevent the member R from rising, one end is shaped as shown in Fig. 5 with a projection which engages loosely in a hole in the wall of the casing. Lateral displacement of the member R is prevented by the provision of a groove in its lower edge to fit loosely over a fixed bar X. The other end of the member R carries a toothed segment C engaging a pinion D fixed on the axis of a graduated cylinder E mounted in the cylinder F. The graduations are read in relation to a fixed mark across a window or opening G in the cylinder F which is enclosed in a casing H secured to the dashboard of the vehicle and provided with a corresponding window or opening I. To enable the apparatus to be zeroized for differently sloped dashboards the cylinder F is made rotatably adjustable in the casing H. The ends Y of the cylinder F may be formed of thin flexible material to accommodate the expansion and contraction of the liquid, and with perforated strengthening plates or frames P.

Title: Method for producing a protective coating on reinforcing iron more particularly for pumice concrete and materials steam-hardened in autoclaves
IPC: E04C5/01
Filed: 1948-10-12
Abstract: A rust-inhibiting coating is formed on iron reinforcements for concrete by applying a mixture of cement and water, with or without lime, sand or the like, or a mixture of lime, water and sand (shale ash, ground stone, fly ash), to either of which mixtures has been added a binder, preferably a collidal adhesive agent, which delays the final hardening of the coating until the reinforcement has been cast in position, but permits rapid drying of the coating, e.g. by hot air, and imparts sufficient strength thereto to avoid scaling during the handling of the reinforcements.  Casein, albumen, bone glue, gelatine, cellulose esters and starch pastes are stated to be suitable binders, and rust-preventing agents, e.g. chromates or bichromates may be added to the mixture which is applied by dipping or spraying.  According to the Specification as open to inspection under Sect. 91, the iron reinforcements are first coated with a solution of the binder, and a coating of dry cement is then applied. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in timing circuits for electronic digital computers and the like
IPC: G11C19/20
Filed: 1957-08-28
Abstract: 866,101. Electronic counting apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 28, 1957 [Aug. 31, 1956], No. 27100/57. Class 106 (1). A chain of electronic triggers arranged for the successive advancement of a single " on " condition by the repeated application of timing pulses is characterized by the fact that the timing pulses are applied to each trigger via an associated gating device arranged to be conditioned by the state of its associated trigger. Each gating device consists of a single diode 29, Figs. 2a, 2b, connected between its associated stage and timing pulse source 62. When a stage is " on," for example stage 1 which comprises triodes V1, V2 and V3, triodes V1 and V3 are conducting, triode V2 is cut-off and its anode, point E, is at a potential of 12v. Under these circumstances a negative timing pulse applied at the cathode of diode 29, point H (lowering point H from its normal potential of 10v. to - 45v., Fig. 3, not shown) passes through the diode 29 and cuts off triodes V3 and V1 which in turn allows triode V2 to conduct, and in this condition stage 1 is said to be " off." Thus a timing pulse is effective on the " on " stage to turn it off, the gate associated with the " on " stage being open. However a timing pulse has no effect on an " off stage since its point E is at - 45v. and its associated gate is closed. The actual advance of the " on " condition is by " advance " connections between adjacent stages. When a stage goes from " on " to " off " its triode V1 applies a positive pulse to the " advance " connection which turns on triode V1 of the following stage. Specification 710,554 is referred to.
