Patent GB-1266372-A (GB)
IPC: G01J3/36
Filed: 1969-07-16
Abstract: 1,266,372. Integration of spectrometer outputs. ANGSTROM Inc. July 16, 1969 [Dec.26, 1968], No.35831/69. Heading G1A. The photo-electric transducers in a spectrometer system are connected into a circuit provided with respective storage capacitors for each transducer and switching means whereby overlapping integration periods for the transducer outputs may be provided. The arrangement is thus suitable for examination of specimens containing both elements which on excitation produce peak intensity output rapidly (e.g. readily volatile elements such as sulphur, tin) and those which reach peak intensity much more slowly (e.g. refractory elements such as tungsten and molybdenum). The light outputs of different elements can be integrated at different times during an excitation period and the resultant stored signals read out later as required to give ratio values as compared with stored reference values. By means of some kind of wavelength selection device each transducer 12 is arranged to produce an output corresponding to a respective element. The transducer 10 produces a reference signal by analysis of an internal standard (i. e. an element in the specimen which produces a constant intensity from early on in the excitation period until the end), or by detection of the total emitted radiation (the non-dispersed radiation), or of a selected group of spectral components. This transducer is connected to a number (in Fig. 1, two) integrator circuits 14, each containing a capacitor 26 which may be connected in circuit (for integration of the reference signal) when required by a respective switch 28 operated by coil 40. Each coil 40 is also associated with a number of switches 34 in the output lines from transducers 12. Thus, when particular element signals are to be integrated by capacitors 32, a reference integrator 14 is operative for the same period. A modified integrator circuit is described with reference to Fig. 2 (not shown) and includes a resistor to prevent arcing between the switch contacts between analyses. The arrangement can be used with self-excited bodies or spectrometers using absorption techniques.

Abstract: 1297669 Umbrella handles H MULLER 7 Aug 1970 [13 Jan 1970] 38225/70 Heading A4P An umbrella which when folded has a rectangular cross-section in plan, has an elongated handle 1 which is mounted for pivotal movement about the shaft 7 between a transverse position, Fig.3 (not shown), in which the handle 1 has its longitudinal extent disposed transversely of the shaft enabling the outer ends of the ribs of the umbrella when folded to be received in a chamber 9 in the handle, and an aligned position, Fig. 1, in which the handle has its longitudinal extent aligned with the shaft 7. The handle 1 comprises a hollow cylindrical housing 2 having a longitudinal slot 3, and is pivotally mounted on a pin 8. One end of the housing 2 is closed by a cap 4 whilst the other end of the housing is provided with a locking  element 5 rotatable relative to the housing. The locking element 5 has a U-shaped slot 5 which receives the shaft 7 when the handle is in its aligned position, and rotation of the locking element 5 retains the handle in said aligned position. In an alternative embodiment, Figs. 4 and 5 (not shown), the locking element 5 is connected to an internal sleeve (10), extending along the inner wall of the housing 2, said sleeve having a longitudinal slot (13) aligned with the opening of the slot 6. To allow rotation of the locking element and sleeve without fouling the pivot pin 8, circumferentially extending slots (11, 12) are provided in the sleeve. For locking the umbrella handle in its transverse position, the shaft 7 may carry a ball (14) at its end which is resiliently mounted for movement along the axis of the shaft, the ball engaging a recess (15) inside the chamber 9 when the handle is in its transverse position. In an alternative embodiment (not shown) the rigid connection between the locking element 5 and the sleeve 10 is replaced by a movable connection, for example a slot and follower pin. In this manner the locking element 5 rotates the sleeve 10 only after the former has been rotated through a predetermined angle. The housing 2 may be open at both ends and be provided with two longitudinal openings 3 opposite each other.

The lines 2 are made by applying heat and pressure to reduce the thickness of the strip by approximately one half along these lines. The former shown in Fig. 1, is used in the making of curtains having pinch pleating in the form of tri-pointed projections, Figs. 2 and 4. The former is laid on the curtain fabric parallel to the upper edge thereof and is stapled in position and then sewn along the upper edge as shown at 5, Fig. 4. The fabric is folded over and the pinch pleats are formed. The pleats may then be held in position by sewing along the bottom and up the back of the pleats, Fig. 5 (not shown). Any staples used for temporarily holding the pleat in position are removed during sewing. The former may have notches 8, Fig. 1, to assist the positioning of the folds. Additional creases 3, Fig. 1, may also be formed to allow for a certain amount of fullness and flexibility in use and, also, the creases may be folded over and stapled, sewn or adhered to shorten the distance between the pleats, Fig. 3 (not shown).

Title: System and method for implementing hybrid automatic repeat request using parity check combining
IPC: H04L1/18
Filed: 2001-12-20
Abstract: A telecommunications system and method for performing error detection on received data packets and error correction on only those data packets that were received in error without the need for retransmission of the data packets or parity checking bits. At the transmitter, the complete data packet is divided into a number of data units (DUs). The DUs are encoded for both error detection and error correction. Both the error correction and error detection parity check bits are separately combined into one or more blocks. Thereafter, the DUs and the block(s) containing the combined parity check bits are transmitted to the receiver. If the receiver determines that a received DU does not contain any errors, the error correction parity check bits for that DU are generated and their effect on the combined error correction parity check bits removed. Thereafter, the remaining error correction parity check bits, which now only contains information about the DUs actually in error, are used to correct the erroneous DUs.
