Abstract: A gasoline internal combustion engine is operated at all times with a full charge of air and is thus unthrottled. At low power levels for such an engine, the ratio of gasoline to air is too lean for normal combustion; therefore, special arrangements are provided by this invention for ensuring combustion.

Abstract: Temperature regulating apparatus for the control of temperature within an enclosure including a temperature measuring circuit which measures the temperature within the enclosure and a semiconductor heating circuit for generating heat responsive to the temperature measuring circuit. The temperature measuring circuit includes a resistive bridge with a temperature sensitive element as one of its legs, the output of the bridge being coupled to an amplifier for developing a temperature signal which varies as a function of the temperature within the enclosure. The heating circuit includes a plurality of transistors having their respective collector-emitter paths coupled in series so that a heating current can flow through the collector-emitter paths of all of the transistors. One of the transistors, designated the control transistor, has its base coupled to the output of the amplifier for controlling the heating current by the temperature signal.

Abstract: A method for producing a permanent combustion under detonating or substanlly detonating conditions within a stream flowing at supersonic speed, consisting in subdividing a stream of combustion-sustaining fluid into two parallel streams, modifying the speed of at least one of said streams, causing said streams flowing at different speeds to meet again inside an area wherein a diabolo-shaped system of shock waves is formed and injecting fuel into the stream flowing at the higher speed, the combustion starting on the downstream side of a flat surface extending perpendicularly to the direction of flow and forming the surface of minimum cross-sectional area of the diabolo-shaped system.

Abstract: Apparatus for measuring the angular velocity and speed of a rotating shaft comprises charge storage elements for storing charge. The charge storage elements are capable of being coupled to the rotating shaft so as to be rotatable about a predetermined axis at an angular speed or velocity related to the speed or velocity of the shaft. A charging brush and discharging brush are positioned relative to the charge storage elements so that the charging brush can charge the charge storage elements at a first predetermined angular position of the latter about the axis and the discharging brush can discharge the charge from the charge storage elements at a second predetermined angular position of the latter about the axis.

Abstract: A toy water gun assembly capable of ejecting water in bursts or in a continuous manner, is disclosed. A separate, pressurizable water container is connected by a flexible hose, to a pistal shaped member. A section of the flexible hose, mounted in the pistol shaped member, is continuously clamped by a lever. A spring biases the lever to prevent the release of a water stream through a nozzle which is mounted on the front of the pistol shaped member. A trigger member having a pointed pawl pivotably mounted thereto, is operatively connected to the lever. An initial movement of the pawl member caused by a quick pull on the trigger member momentarily removes the lever from its position clamping the hose. Additional movement of the pawl causes it to slide off the lever, thereby allowing the lever to return to its regular position wherein the hose is clamped.

Abstract: An optical-fibre connector comprises a support piece 1, a first locking piece 2 and a second locking piece 3. Locking pieces 2 and 3 are respectively fixed to the support piece 1by screws 4 and 5 which are engaged in cylindrical bores containing sleeve of elastomer material. The locking piece 2 comprises at its base two bearings 8 and 9. To connect two series of optical fibres, two identical connectors are disposed end to end and connected by two spindles 10 comprising a threading 11 which engages in a metallic sleeve 12 containing a sleeve 13, made of an elastomer material. This assembly permits absorption of vibrations and limitation of the clamping in order to avoid breaking of the optical fibre during use or connection of the two series of optical fibres.

Abstract: A retaining clip for retaining a threaded screw on a wall of an outlet box has a pair of legs extending generally parallel from a bite portion and which are received in slots in the wall extending across an elongated screw receiving passage. Each leg has an opening having a diameter substantially equal to the major diameter of the thread and each opening has a projection having an inner arcuate edge having a radius of about one-half the minor or root diameter. At least one of the openings has its center axially offset from the axis of the passage so that a line through the two centers is inclined with respect to the axis of the passage.

Abstract: In a method for forming a module having a floor, a roof and opposing sides, a concrete floor is first poured and, once solidified, moved into position between tilted wall molds. Inexpensive hollow masonry blocks are then dry-stacked in rows against the wall molds; that is, they are loosely stacked without mortar therebetween. Spaces with reinforcing rods therein are left along the outer wall molds at each end of the stacked blocks. Inner wall molds and, for some modules, a roof mold are then moved into place adjacent the stacked blocks. With the wall molds vertical, the blocks are pressed between the inner and outer wall molds. Concrete is poured into the spaces at each end of the stacks of blocks to form structural posts and over the tops of the stacks of blocks to form structural spandrel beams. Additional hollow blocks are laid across the roof mold and concrete is poured over those blocks to complete the roof.

Abstract: An electromagnetic tripping device for protecting a printed circuit card by opening an electrical circuit of the card in response to an overcurrent of the circuit. The device includes contacts and an energizing coil which are connected in series with the circuit to be opened. When the contacts of the device are closed and the circuit current is normal, a magnetic holding flux provided by a bar magnet holds a plate in contact with two spaced and parallel side-walls between which is located the bar magnet. When an overcurrent occurs, the energizing coil produces a breaking flux which reduces the holding flux sufficiently so that the plate may be moved from the side-walls by a return spring, thereby opening the contacts and the circuit. When the plate is moved from the side-walls, an actuating rod which passes through an opening in the plate is projected out of the device housing to indicate the opening of the circuit.

Abstract: Bipolar switches in first conductive leads mounted in a dielectric panel are divided into successive groups of alternating polarity and additional pairs of leads are positioned in the panel adjacent each first lead to couple the groups of switches in each first lead in parallel. A reduced reversed biasing of the additional leads results in the first leads being selectively rendered discontinuous by the switches, changing the electrical characteristics of the panel to shift or focus a microwave beam passing through the panel. The additional pairs of conductive leads also operate as microwave elements to increase the bandwidth of the panel.
