Filed: 1975-02-12
Abstract: 1480750 Hinges IHW ENG Ltd 12 Feb 1975 [11 May 1974] 20910/74 Heading E2F In a hinge comprising two members 1, 2, a second member 2 is secured to a door 9 and a first member 1 is secured to a frame 8 having a door opening therein, the members 1 and 2 are mounted about a pin 7 and a leaf spring 4 is secured to the first member 1 for co-operating with a nose portion 2b of the second member 2 when the two members are in a predetermined angular position to hold the two members in that position relative to one another. As the door is opened the nose portion 2b swings about the pivot pin towards the leaf spring 4, an arcuate face 2c of the nose 2b will eventually contact the spring 4 and restrain further opening of the door 9. Sufficient further force in the opening direction of the door will enable the spring 4 to be depressed as the nose 2b pushes against it. Further movement will cause the spring 4 to be deflected until a point is reached when the surface 4a of the spring 4 contacts a substantially planar face 2f, the face 2e of the nose 2b then being in face to face contact with the interior surface of the member 1. In this position the door 9 is held against further opening by abutment of members 1 and 2 against one another, member 2 being urged into such abutment by cooperation of face 2f and surface 4a. To close the door pressure against the resistance of the spring 4, the spring is deflected and the nose 2b is forced out of contact with the surface 4a of the spring 4. The spring then returns to its initial position and the door 9 is swung into the closed position. In a modification (Figs. 5 and 6 not shown) a roller comprises the nose 2b of the member 2.

Abstract: 1503948 Pulse width modulation LICENTIA PATENT-VERWALTUNGS GmbH 16 May 1975 [16 May 1974] 20945/75 Heading H4L [Also in Division H2] In a circuit for production of A.C. power pulse width modulated waveforms are fed to the primaries of a pair of transformers Tr1, Tr2 in such a way that the secondary of one transformer produces positive halfwaves of the required output whilst the secondary of the other produces the negative halfwaves; switching devices T1, T2 being provided to short circuit the respective output when it is not producing power. The invention is applicable to production of a power frequency sine wave (e.g. 50, 60 or 400 Hz) by following the instantaneous value of a reference sine wave from a source 25 the frequency of which is determined by a 10 kHz-100 kHz pulse generator 23 via a divider 24. A triangular wave is generated at 22 and compared with the instantaneous value of power frequency sine waves from amplifiers 26, 28 by means of comparators 20, 21, operating on respective half cycles of the reference sine wave to produce pulse width modulated rectangular waves. These waves are fed via drivers 18, 19 to switching transistors 16, 17 which alternately switch the primaries at transformer Trl, Tr2 across a D.C. source 15. The secondary voltages are rectified by diodes D1, D2 and smoothed by capacitors C1, C2 so as to provide the required power waveform U. Transistors Tl, T2 short circuit the respective output when it is not producing power and are turned on by rectifying the output of auxiliary windings 13, 14. Waveforms representing the positive and negative half cycles are fed to differential amplifiers 29, 30 which compare the output with the reference sine waves 25, 27 and adjust amplifiers 26, 28 accordingly. In Fig. 4 (not shown) transistors T1, T2 are respectively turned on by in phase and anti phase amplified versions of the reference sine wave.
