Abstract: Abstract of the Disclosure A device for setting the time of actuation of a buzzer or other signal generator in an alarm clock comprises a flexible stem of a manually operable knob, rotatably journaled in two mounting plates, which carries a pinion normally engaging gear teeth of a disk freely rotatable about the hour shaft of the clockwork, the disk being under axial spring pressure urging it against an adjacent hour wheel which has one or more outouts adapted to receive respective sawtooth-shaped cams on a confront-ing disk face when the wheel reaches the selected angular posi-tion.  The user may turn the knob in either direction to advance or delay the selected time setting, except that any delay of 12 hours or more from the time of resetting is prevented by the interengagement of a steep cam flank with an edge of the associ-ated cutout.  If the user nevertheless turns the knob beyond that limit, the stem yields laterally and disengages its pinion from the disk teeth to obviate any damage to the mechanism.

Abstract: ABSTRACT A layer of CdxHg1-xTe is grown on the surface of a substrate by decomposing alkyls of cadmium and telluride in a mercury atmosphere.  The substrate is placed in a vessel containing a mercury bath with the vessel and bath at a suit-able pressure and a temperature below the alkyl decomposition temperature. Hydrogen is passed through bubblers separately containing alkyls of cadmium, telluride and, if required, a dopant into the vessel.  The substrate is indepen-dently heated above the temperature of the vessel so that the alkyls decompose on the substrate.  The substrate may be CdTe, a II-VI compound or mixed II-VI alloy.  The alkyls may be dimethyl cadmium, diethyl cadmium, dipropyl cadmium, dimethyl telluride, diethyl telluride, dipropyl telluride, dibutyl telluride etc, or hydrogen substituted tellurium alkyls such as hydrogen ethyl telluride etc.

In order to attain, over a large output area of the condenser, only slight pressure differences between the outlet-sided ends of the pipes located consecutively in the cooling gas stream, the ratio of the outer heat transfer surfaces, formed by the surfaces of the crossribs (4) and the pipe (1), to the diameter of the pipe (1) first contacted with the cooling gas is, on the one hand, chosen smaller in relation to the ratio of the outer heat transfer surface (5, 2) to the diameter of the pipe (2) each of subsequently contacted with the cooling gas and, on the other hand, the flow cross section of this pipe (2) subsequently contacted with the cooling gas is chosen smaller in relation to the flow cross section of the pipe (1) always previously contacted with the cooling gas.  Preferably, at least two pipes (1, 2), formed with circular yet different-sized flow cross sections, are ribbed with crossribs (4, 5) of equal outer dimensions and equal division.

Abstract: HYDRAULIC CYLINDER EXTENDING IN THREE FORCE MODES              ABSTRACT OF THE DISCLOSURE     A multiple mode hydraulic piston assembly employing a regenerative hydraulic circuit which when incorporated in the piston of a hydraulic cylinder and assembled with a pressurized hydraulic source through appro-priate piping and valving, will sequentially permit, restrict, and block liquid flow through the piston and will thus extend its piston rod in multiple force modes, namely a low force rapid extension mode, a moderate force rapid extension mode, and a high force extension mode.  In response to fluid pressures within the cylinder chamber the multiple mode piston assembly automatically changes operational modes.  First bi-directional flow is provided between opposing chambers, then uni-directional flow is provided from the rod end to the back end chamber, and finally flow between the chambers is blocked;  A modified embodiment provides a free motion mode wherein a modest external force can displace the piston in either direction. An additional embodiment provides an arrangement of the elements offset from the geometrical axis of the piston.  An embodiment of the foregoing construc-tion provides a double-ended piston rod configuration.
