Patent GB-135672-A (GB)
IPC: H01H43/30
Abstract: 135,672. Fagerlund, E. A. Dec. 23, 1918. Thermal switches. -A short-time thermal switch for staircase lighting &c. comprises a thermal element made up of a flat coil of wire a held at its ends and connected at its middle to the contact-member f which co-operates with two pivoted contact-arms h<1>, h<2> loaded by the weights k<1>, k<2> so that their lower ends tend to take up a position against the adjustable stops l', l<2>. When the staircase button m is depressed, the thermal element is connected to the mains through the contact-member f and the contact-arm h<2>. The resulting expansion of the thermal element causes a movement of the contact-member to the left under the action of the spring d. If the button m is held depressed, the heating-circuit remains completed until the contact-arm h<2> is held up by the stop P. The contact-arm continues its movement and, by engagement with the arm h<1>, completes the lamp circuit, which is again broken only after the thermal element, which is now deenergized, has contracted sufficiently to take the contact-member past the held-up position of the contact-arm h<1>. By adjusting the positions of the stops l<1>, l<2>, the time during which the lamps are illuminated may be varied. The thermal element may consist of a flat coil p, Fig. 3, wound on insulation o, and enveloped by insulating- material q. Further to conserve the heat, a conductor s in series or parallel with the heating- conductor p may be wound round the flat body.

Patent GB-1465189-A (GB)
Title: Musical instruments
IPC: G10H1/28
Filed: 1974-03-27
Abstract: 1465189 Arpeggio generator NORLIN MUSIC Inc 27 March 1974 [7 May 1973] 13640/74 Heading G5J In a musical instrument arpeggios can be generated over one, two or three octaves from the notes actuated on a sequentially scanned keyboard, the scanning being halted for a predetermined interval each time an actuated key is scanned thus giving a constant duration to the generated notes. When the foot switch 90 is opened, a scan oscillator generates pulses, preferably at about 1kHz., which are applied to an up-down 4-bit counter 28 via two buffers 32, 33 one of which is actuated by a panel switch 42. The counter outputs are connected to a 1-of-16 decoder 18, twelve of the outputs 20 drive gates 14 while a thirteenth 19 pulses a 3-bit counter 76 which thus records the number of scans made over the twelve outputs. A lower-manual keyboard 22 having twelve keys is connected to the gates 14 also and a combination of an operated key and a scan signal on the corresponding line of 20 opens the relevant gate allowing a control signal to pass to the arpeggio keyer 10. This routes the signal to one of 36 lines according to the outputs of the octave enable control 84. The panel mounted mode selector switches 42 define the number of octaves to be scanned over and as each scan is completed, counter 76 increments varying the signals on 80, 82 to enable a different octave output from the arpeggio keyer. When the chosen arpeggio pattern has been completed all outputs 12 are cut off. Closure of foot switch 90 resets both counters 28 and 76 and simultaneously stops the arpeggio in mid-flight. The thirty-six outputs 12 are connected to conventional keyers (not shown) placed between a tone source, voicing elements, and an audible output (none shown). When any actuated key is scanned a signal is supplied on line 66 from the gates 14 to enable strobe switch 62 which on the next negative transition of the scan oscillator 44 passes the signal to the up-down-transfer-stop disable 70 and this triggers the start-stop flip-flop 52 to inhibit further transitions from the scan oscillator 44. After a time set by the arpeggio speed control 58 a timer multivibrator 54, which preferably runs at about 4Hz., changes state resetting the flip-flop 52 allowing scan oscillations to restart. Thus any operated key results in an output keying signal at 12 which lasts for a time set by the arpeggio speed control 58. Among the patterns of arpeggio that can be obtained are some passing up through octaves and then back down again. To avoid sounding the same note twice, once before and once after reversal, a change of signal on line 40 not only changes the counter inputs over by controlling the buffers 32, 33 but is also applied to the updown-transfer-stop-disable 70 on line 74 and inhibits the passage of the strobe switch 62 output, thus the scan oscillator is not halted. Detailed circuitry is given in Figs. 2A to 2E (not shown).

Patent GB-495786-A (GB)
Title: Improved process of manufacturing laminated glass
IPC: C03C27/10
Filed: 1937-05-18
Abstract: Safety glass consists of sheets of glass bonded to an interposed sheet composed of high viscosity cellulose organic ester of at least 500 seconds viscosity and containing at least 100 per cent of a plasticizer calculated on the weight of the ester.  The ester may contain a small proportion of butyryl or propionyl radicles.  The viscosity figure is the time taken for a steel ball of five-sixteenths of an inch diameter to fall 10 inches through a solution maintained at 20 DEG  C., of one part of the ester in 4 parts of acetone in a vessel of 1 inch diameter. Suitable high viscosity cellulose esters are those prepared as described in Specification 467,160.  In an example, a sheet is cast from a solution containing cellulose acetate of 500 seconds viscosity and 100 per cent, calculated on the weight of the acetate, of dimethyl phthalate.  The sheet is bonded between glass using an adhesive obtained by reaction between gelatine and a polyglycol.  In another example, there is used a plastic sheet containing cellulose acetate of 7,000 seconds viscosity and 150 per cent of benzyl benzoate.  In a third example, the plastic sheet consists of cellulose acetate propionate of 20,000 seconds viscosity and contains 150 per cent of tributyrin.  A number of other suitable plasticizers are specified. The product has a high resistance to shattering under impact at relatively low and relatively high temperatures.  The Specification as open to inspection under Sect. 91 refers also to the manufacture of yarn from a mixed cellulose ester having a viscosity of over 200 seconds, and includes an example in which a cellulose acetate containing 1-6 per cent of propionyl radicle and having a viscosity of 200-800 seconds, is dissolved in aqueous acetone and spun into hot air.  Tables are given comparing the wet and dry strengths of this yarn and ordinary cellulose acetate yarn.  In another example, an ester containing 1-6 per cent of butyryl radicle and having a viscosity of 200-800 seconds is employed.  This subject-matter does not appear in the Specification as accepted.

Filed: 1938-05-10
Abstract: 496,923. Brakes for trailer vehicles. ARX, A. VON, and NEIDHART, P. May 10, 1938, No. 13972. [Class 103 (i)] In brake mechanism for trailer vehicles whereby the brakes are applied when the trailer overruns the tractor, and by the fall of the towing yoke the towing yoke is connected by links to the trailer and a brake operating thrust rod is connected at one end to the yoke and at the other to a friction shock absorber to ensure smooth application of the brakes. The forked draw-bar a is connected by links b to the turning fore-carriage of the trailer and a centrally arranged thrust-rod g is connected to the arm h of a friction shock absorber, the other arm i of which is connected by a rod l to the brakes. The shock-absorber comprises stationary and rotatable friction discs mounted on the pivot k. The brakes are thus operated by rearward movement of the bar a under the restraint of the shock-absorber when the trailer tends to overrun the tractor. The brakes are also applied by the fall of the drawbar if the coupling breaks. Upward movement of the links b is limited by stops e provided on the links, and pins s can be inserted in fixed sockets r to engage the stops to prevent downward movement of the links and application of the brakes when it is desired to back the vehicle.
