Title: Lock for Portable Container
IPC: E05C19/14
Filed: 1979-08-02
Abstract: The present invention relates to a locking device for portable containers which comprises a lug 1 adapted for being fixed on the body of the container 3, a lever 6, to engage container cover 10, a link 4 connecting the lever 6 with the lug 1 by means of two parallel hinges 5 and 7. A stirrup 8 e.g. on the end of a carrying handle is introduced into longitudinal slots 12 provided on the lever 6, said slots coinciding with a transverse groove 13 provided on the lug 1 in a closed position. As a result, when the lever 6 is moved to the locked position and the handle is lifted to carry the container the stirrup 8 enters the groove 13, thereby fixing the lever 6 from accidental displacement relative to the lug 1. <IMAGE>

Title: Method for coating a substrate using a curable silicone release composition
IPC: B29B15/00
Filed: 1980-02-18
Abstract: An improved coating process comprises applying to a substrate certain curable silicone release compositions which have a ratio of silicon- bonded hydrogen radicals to silicon- bonded vinyl radicals of 2-10 and comprise a vinyl-terminated polydiorgano- siloxane, a vinyl-containing, xylene- soluble siloxane resin copolymer, a methylhydrogenpolysiloxane and a hydrosilylation catalyst.

Title: Lasers
IPC: H01S3/034
Filed: 1980-03-07
Abstract: A mirror mounting arrangement for a gas laser, in which the end faces of a tubular laser body 1 are ground and polished to the required accuracy and form direct seatings for the end mirrors 5. Each mirror is mounted in an annular frame 6 having an external thin flange 7 remote from the mirror position.

Title: Mechanical Torque Converter
IPC: F16H3/42
Filed: 1980-07-04
Abstract: Multiple slotted drive disks 10a, 10b are secured in parallel relationship to a drive shaft 14. The slots are radially arranged and the slots of each disk are aligned. Movable rods are received in the slots. A slotted driven disk 30 is secured to a driven shaft 36, which driven shaft is parallel to the drive shaft The drive and driven disks are arranged in parallel intersecting relationship such that the rods will be received in the slots of the driven disk through a portion of the revolution. Relative movement is effected between the shafts via the rods, and the relationship of angular velocity between the shafts is kept constant. The radial position of the rods relative to the drive disks is controlled by a cam plate 60 and by solenoid- operated retractable guides 40, 42 in fixed side plates 50 whereby the rods are caused to engage each slot or alternate slots only in the driven disk thereby providing two ratios. Modifications are described enabling other ratios to be obtained. <IMAGE>

Title: Device for feeding warp and controlling its tension in circular loom
IPC: D03D37/00
Filed: 1979-04-28
Abstract: A circular loom controls the tension of a warp by a unit for feeding the warp through the contact frictional force with a yarn and a yarn guide having an elastic member for absorbing variations in tension. A dancing lever (40) having a warp guide (40b) to a heald is always engaged with a first spring (40c). Since a second spring (40d) comes into cooperation with the first spring (40c) when the lever (40) rotates more than a predetermined angle due to an abnormal tension, it can absorb large tension variations in tension mainly caused by a shed-forming motion. On the other hand, the warp (3) fed from a creel is fed in response to the warp tension by the action of the contact frictional force with the outer peripheral surface of a roller (54) which rotates with a peripheral speed faster than the speed of the fed warp. <IMAGE>

Title: Method and Apparatus for Detecting the Presence of a Contaminant in a Gaseous Carrier
IPC: G01N27/00
Filed: 1981-04-10
Abstract: The invention concerns the detection of contaminant in a stream gas. Previous methods have either been insufficiently sensitive or have been slow and needed skilled operatives. The present invention allows speedy operation with relatively unskilled operatives. A piezo electric crystal oscillator (1) is allowed to oscillate for a known period of time and the number of oscillations is counted. For a known time the crystal is exposed to contaminant, and is then allowed to oscillate again for the same period of time as before and the oscillations again counter. The difference in number of oscillations is a measure of the mass of contaminant deposited on the crystal (1). The period of oscillation of the first crystal is determined by a second matched crystal oscillator (2) in which the crystal is exposed to the same environment but not to contaminant. The apparatus has the advantage of being self-zeroing, and the exposed crystal (1) does not need cleaning after each use. The invention has special application to the testing of medical gases, for example oxygen and nitrous oxide. <IMAGE>

Title: Device for digitizing an analog signal
IPC: A61B5/0452
Filed: 1981-10-05
Abstract: A device for digitizing an analog signal whose mean value is constant, comprising a delta modulator (3) which is arranged to sample the signal during successive time intervals, each of which has a duration which corresponds to n pulses of a clock pulse generator (11), and to supply m (m < n) pulses per time interval  DELTA T, m being dependent on the difference between the values of the signal at the beginning (T) and at the end (T +  DELTA T) of the interval. The clocked output of the delta modulator (3) is applied together with the clock pulses to a bidirectional counter (5) arranged to count in one direction or the other in response to the corresponding presence or absence of a modulator output pulse during a clock pulse, and the running total count is applied as a digital input value to a correction circuit (7) which is constructed as a digital high-pass filter (Figure 3) in order to remove error signals which are added to the signal due to inaccuracies of the delta modulator, by forming the progressive mean value S(T) of the counter output signal and subtracting this from the counter output S(T +  DELTA T). <IMAGE>
