Title: Attenuation meter for two-wire telephone line - uses two test voltages and requires no extra test wire
IPC: H04B3/48
Filed: 1970-01-15
Abstract: The attenuation measurer, for two-wire telephone lines, needs no extra test wire and has the two-wire line (PL) connected via two-wire/four-wire interfaces (Gas, Gae) to the test units (MA), (MB) at each end of the line. To measure attenuation from the first end (MA), a second test voltage is applied at the second end (MB) at the same time as a first test voltage at the first end. The transmitter and receiver of the second end are then connected together and the second test voltage disconnected. Measurements are made both with the two voltages present and with only the first present.

Title: Correction circuit for opto-electronic gauge for rolled stock - detects lateral displacement error using coincidence gates
IPC: G01B11/10
Filed: 1970-04-02
Abstract: The equipment for measuring the cross-section of wire and rolled stock uses pairs of lenses and detectors on a rotating ring encircling the rolled stock. Measurement error can arise due to the lateral movement of the stock at right-angles to the optical axis. The error-correction circuit detects the phase relationship between pulses from the pairs of measuring detectors. In-phase pulses indicate zero displacement error. The detector outputs are taken to respective differentiators. The output pulses of the differentiators are taken to a coincidence circuit comprising pairs of flip-flops whose inputs are diode-polarised. The sum and difference signals derived are integrated and this signal is taken to a function circuit. The output of this feeds the compensation circuit in the measuring channel.

IPC: B23B9/12
Filed: 1970-11-18
Abstract: A pneumatic tool particulary equipped with means for dispensing glue and for driving dowels into holes, has a cover for the opening of the release mechanism. This opening (76) is connected via a throttle (77) to a portion of a compressed-air passage (84) in the tool, and release is effected by manual closing of the opening. There can be a control slide valve at the outlet, initiating operations on closure of the opening, which can be situated in the handle (1). The tool can be so designed that the opening must be uncovered again in order to reset it. All operations can be arranged to occur at preset time intervals after release, and thus are unaffected by external action.

Abstract: It has been found that layers which include arsenic and/or zinc can have an adverse effect upon optoelectronic semiconductor devices such as lasers. This is reduced by treatments in which arsenic and zinc are excluded. Preferably the substrate is cooled from reaction temperature in the presence of a mixture of hydrogen and PH3 (replacing AsH3 and/or Zn(CH3)2 used to grow the final layer). Alternatively, devices having a contact layer of heavily p-type gallium indium arsenide are improved by the deposition of a protective layer of indium phosphide. This layer is removed immediately before metalisation. Even though the protective layer is not present in the final product it has a beneficial effect.

Abstract: A laser imaging material which can be effectively employed for color printing and proofing comprises a near infrared transparent support film which has a near infrared absorbing layer thereon. The absorbing layer contains at least one sensitizer which is absorbent at a desired near infrared laser output wavelength and a decomposable binder. Laser radiation at the desired wavelength which acts upon the absorbing sensitizer causes rapid partial decomposition of the binder into gaseous and non-gaseous products. The rapid expansion of the heated gases causes ablation of inert materials from the surface of said layer onto a receptor sheet thus producing an imaged film (i.e., the laser imaging donor material) and a color print or proof (i.e., the receptor sheet) of reversed sign to the imaged donor material.

Abstract: This invention pertains to a process for electrochemically modifying electrochemically roughened aluminum or aluminum alloy-based support materials for printing plates. An aluminum or aluminum alloy-based support material is electrochemically roughened using alternating current in an electrolyte containing at least one from the group consisting of hydrochloric acid and nitric acid. Subsequently, at least one surface of the material is treated in an aqueous electrolyte, with the roughened material being made the cathode. The cathodic treatment results in removal of material from the surface in the order of from 0.1 to 10 g/m2, and is carried out in an aqueous electrolyte which has a pH value in the range from 3 to 11 and includes at least one water-soluble salt in a concentration ranging from 5 g/l up to the saturation limit thereof. The cathodic treatment is appropriately conducted using direct current at a current density from 3 to 100 A/dm2, at a temperature from 15 DEG  to 90 DEG  C., and for a duration from 5 to 90 seconds. The removal of material is optionally followed by an anodic oxidation of the support material and a hydrophilizing post-treatment of the oxide layer. Support materials which have been prepared in this manner are used in the manufacture of offset printing plates carrying a radiation-sensitive coating.
