Examples of (b) are acrylic acid and 2-(methacryloyloxy)ethyl  5-carboxycyclohex-1-ene-4-carboxylates. Examples of (c) are pentaerythritol tetrathioglycollate, trimethylol-propane trithioglycollate,  and 3,6-dioxa-1,8-dimercapto-octane.     The compositions may be polymerised by means of actinic irradia-tion in the presence of an added or "built-in" photosensitiser or by the action of a free-radical catalyst. They are especially useful in the production of printed circuits.

Abstract: Abstract of the Disclosure A pulse generator for a television receiver produces keying pulses during the video signal back porch interval in order to energize burst gate and brightness control circuitry. The pulse generator is triggered by horizontal sync pulses under strong/ noise-free video signal conditions.  As the quality of the video signal and the horizontal sync pulses deteriorate due to noise or a weakening signal, the pulse generator is triggered by horizontal retrace pulse in order to provide keying pulses under all video signal conditions.

Abstract: TITLE             A GaAs-GaA1As PHOTOCONDUCTIVE DETECTOR                          INVENTORS                     Julian P. Noad Robert H. Hum ABSTRACT OF THE DISCLOSURE The photoconductive detector for high frequency optical signals includes a substrate, an active layer and a barrier layer between the active layer and the substrate.  The active layer absorbs the optical energy and generates a photoconductive current detected at spaced elec-trodes on the active layer.  The barrier layer interface with the active layer reflects some of the optical energy which has traversed the active layer without being absorbed.  The barrier layer transmits the optical energy which is not reflected, into the substrate where it is absorbed, however, any carriers generated are prevented by the barrier layer from diffusing into the active layer.

Abstract: ABSTRACTS OF THE DISCLOSURE          A multiple aptitude testing device for electronically evaluating an examinee's capacity or aptitude toward performing various vocational tasks.  The device includes a test station which affords five general types of examinations, namely, objec-tive question and answer tests, a manual dexterity test, a finger dexterity test, a hand/eye coordination test, and a hand/eye/foot coordination test.  The question and answer examinations entail interchangable overlays which contain questions and possible answers such that the examinee selects what he deems is the correct answer by contacting an appropriate sensor on the housing with an electrically conductive answer probe.  The other four examinations entail means for electronically measuring the number of times the examinee is able to perform a manipulative task during a fixed period of time.  The device provides electronic means for automatically grading the examinations and displaying or printing a test score associated with each of said tests.  The device 20 is further designed to generally recognize which test is being conducted based on which of the various attachments or overlays are connected to the device.        Although the test station is generally self-contained, e.g., not requiring separate answer booklets, writing utensils, etc., the preferred embodiment of the device entails using a separate master control unit which enables simultaneous, synchro-nized control of up to four test stations.

Abstract: ABSTRACT           A switched mode power supply (10) for a remote controlled television receiver incorporates a degaussing circuit (19) having a relay (17) that is required to be energized in order to permit operation of the degaussing circuit (19).  Power to energize the relay (17) is derived from a power supply switch transistor protection circuit (76) which removes residual stored energy from the power transformer primary winding (22).  This stored energy is used to charge a capacitor (80) during the time the switch transistor (65) is nonconductive.  The capacitor (80) is discharged to provide current to energize the degaussing circuit relay (17) in order to permit ac mains current to flow through the degaussing coil (15).

Abstract: COMPUTER TERMINAL STAND     Abstract of Disclosure A stand for a computer display terminal is described which enables the terminal to be tilted in a vertical direction, swiveled in a horizontal plane and adjusted in height.  The height adjustment is accomplished by a pair of telescoping posts attached between a swivel base member and tilt carriage arms on opposite sides of the computer terminal.  A gas cylinder is provided to counterbalance the weight of the terminal and is connected to the telescoping posts by flexible connectors, such as metal cables.  As a result, the user adjusts the height by merely overcoming the friction of the telescoping posts, the pulley system and the gas spring since the weight of the computer terminal is counterbalanced by the gas cylinder.  A releasable brake is provided on the base member which also includes a glide means for enabling gliding movement of the stand over a support surface only when the brake means is released.  The brake includes a brake pad which engages the support surface at a position under the swivel axis of the base member so that the stand can swivel about such axis when the brake means is engaged.
