Title: Digital communications system
IPC: H04L1/02
Filed: 1982-01-26
Abstract: A slow speed hf communications modem employs frequency and time diversity to overcome transmission problems due to noise, multipath etc. A digitally encoded signal is transmitted consecutively on five complementary 2-tone channels distributed within the hf band. A unique start-of-message (SOM) signal is generated (9) to precede a message transmission and an end-of-message signal (EOM) follows the message. The SOM signal is detected (18) to produce an accurate timing pulse (20) which initiates a clock in the receiver modem arranged to sample each channel tone at times appropriate to receiving message signals. The noise in each channel tone is also sampled before (pre-data bit) and after (post-data bit) a signal data bit and the measured pre- and post-data bits are combined to assign a weighting factor to the associated message data bits. By providing SOM and EOM signals the modem is able to operate unattended. <IMAGE>

Title: Improvements in or relating to stepping electric motor driven electronic timepieces
Inventor: KITANO MASUO
IPC: G04C3/14
Filed: 1982-04-21
Abstract: In a stepping motor driven electronic timepiece a detection pulse is supplied to the motor coil to set up, across a detection resistance, a detection voltage the magnitude of which is indicative of whether the motor is in a rotation or a non-rotation condition. A path for the detection pulse current is established through the detection resistance and the coil in series only after establishment of a path which does not include said resistance. In Figure 8 the motor coil is shown at 7, and 40, 41, 42, 43, 44 and 45 represent electronic switches. 24 is the detection resistance. Figure 8a shows the switching state in which there is no detection current path; Figure 8b shows the path 46 in which the coil is included and the detection resistance is not; and Figure 8c shows the path 47 in which the coil and the detection resistance are in series. <IMAGE>

Title: Floating seal in an earth boring bit
IPC: F16J15/32
Filed: 1982-05-04
Abstract: An earth boring bit has a bearing seal that floats to accommodate angular and axial movement of the cutter 31 with respect to the shaft 15. The seal is located in an annular groove 17 formed in the shaft 15. A supporting ring 23 is located in the groove 17.

Title: Billet equipment
Inventor: STUBBINS DEREK
IPC: B23Q7/16
Filed: 1982-01-27
Abstract: An installation for inspecting and dressing billets (13) issuing from a billet mill has a moving beam conveyor which includes dogs (17) for intermittently moving the billets along the conveyor path. That path passes through four stations at each of which there is an inspection/dressing location (21) consisting of a walkway above the conveyor. A lifting mechanism (23) at each station lifts a single billet off the conveyor and presents one face of the billet to an operator on the walkway for inspection and dressing. The billet is then returned to the conveyor, turned over by a turnover mechanism (25), and moved to the next station for similar treatment of the next billet face. On leaving the final station, the billet has been inspected and dressed on all four faces.

Title: Integrated optic devices
Inventor: MOROZ JOHN
IPC: G02F1/335
Filed: 1982-09-29
Abstract: Alignment of an optical beam (not shown) with a waveguide (2) of an integrated optic device (6) is facilitated by mounting the device on an alignment unit (5) adapted to adjust the position of the waveguide (2) relative to the beam in, for example, the z and  theta x directions. The alignment unit comprises two spaced metal bars (7, 8) separated by thermally insulating material (11) whose temperatures, and thus their physical lengths, are adjustable by means of respective thermoelectric heat pumps (9, 10). The optical power coupled to the waveguide may be monitored and employed in an electronic feedback loop (Figure 3 - not shown) in order to dynamically control the temperatures (T1, T2) of the bars (7, 8) and thus the alignment of the beam and waveguide in the z and  theta x directions, for optimum optical throughput of the waveguide. A laser printer may employ this alignment method for aligning a laser beam modulated with the information to be printed with the waveguide of a surface acoustic wave device acting as a laser beam deflector. Acoustic waves generated in the waveguide are employed to scan the laser beam over a photosensitive surface moving transversely to the scan direction. <IMAGE>

Title: Method of producing fiber reinforced glass matrix composite articles of complex shape
Inventor: LAYDEN GEORGE K
IPC: B29C63/00
Filed: 1983-05-06
Abstract: A method of making fiber- reinforced glass composite articles of complex shape is disclosed which overcomes problems associated with the debulking process common with such procedures. Sheets of woven or non-woven fiber reinforcement are impregnated with a layer of thermoplastic binder containing glass powder and optionally, additional carrier liquid. The thus treated sheets are then dried and cut into a plurality of preforms corresponding to the predetermined pattern of the article being fabricated. The thus treated preforms are then stacked in a mold and warm molded to form an intermediate article of near net shape, during which molding operation much of the ultimate debulking occurs. The intermediate article is then hot pressed to form the final fiber reinforced glass matrix article of net shape and high strength and toughness. These multiple heating steps may also be accomplished in a single molding operation. Fig. 4 shows a finished article. <IMAGE>

Title: Latch mechanism having pull- in action
Inventor: BISBING ROBERT H
IPC: E05B17/00
Filed: 1984-08-30
Abstract: A latch mechanism of the pull- up type for a cabinet door is latched and unlatched by turning the latch mechanism in one direction or the other. When the door is in latched position, rotating the mechanism in the unlatching direction initially causes a spring-biased shaft (50), which carries a latching pawl (70), to move axially inwardly. This inward movement of the shaft is permitted because a sleeve cam (20) having cam slots (25) is moved rotationally to present inwardly sloping cam surfaces to opposite ends of a cross pin (60) which is mounted on the shaft and which functions as a cam follower. The shaft is prevented from rotating on its own axis until the cross pin (60), which also functions as a motion- control pin, is moved axially inwardly a sufficient distance to escape from axial motion-control slots (41) provided in a motion- control sleeve (40) which is mounted coaxially on the shaft. When the motion-control pin, reaches the inward ends of the axial motion-control slots, the opposite ends of the cross pin are able to move laterally into lateral motion- control slots (42) provided in the motion-control sleeve, thereby to allow the shaft and the latch pawl to move pivotally out of the way of the cabinet frame. To latch the door, the action described takes place in reverse order. <IMAGE>
Patent GB-2167842-A (GB)
Title: Safety valve
Inventor: MEADOWS ROBERT
IPC: F24H9/20
Filed: 1984-12-04
Abstract: A safety valve 2 operable to release automatically a large increase in fluid pressure beyond the normal fluid working pressure in a hollow casing 3 of an instantaneous water heater 1. The safety valve 1 comprises a silicone rubber plug 10 located in a through bore 9 of a tubular element 8 detachably mounted in an opening 12 in the casing wall. The plug 10 is an interference fit in the bore 9 to seal the bore under the normal fluid working pressure. The bore 9 has an orifice 18 of reduced diameter and the plug 10 is ejected from the bore by an increase in fluid pressure within the casing sufficient to compress and extrude the plug 10 through the orifice 18. The pressure increase required to eject the plug 10 is controlled by the physical characteristics of the silicone rubber and the relative dimensions of the plug 10 and orifice 18 and may be set for any given application as desired. <IMAGE>
