Abstract: 1301497 Indicating wear of disc-brake pads AISIN SEIKI KK 2 Nov 1970 [1 Nov 1969 25 June 1970(2)] 51988/70 Heading F2E A disc brake is provided with a wear-indicating device comprising an electrical circuit which is normally held closed by a holding element but which is adapted to be interrupted when the holding element contacts the brake disc, and warning apparatus operable in response to interruption of the electrical circuit. In the floating-caliper spot-type disc brake of Fig. 1, an insulating plunger having a flange 402 and projection 403 located in a backing plate 32 has also a conductive contact member 405 which is urged into contact with a metal spring retainer 406 screw-threaded into the backing plate by a precompressed compression spring. The circuit including the backing plate 32, parts 406, 405 and wire 408 ("earthed" to the chassis or the like), is broken when, after pad-wear, projection 403 contacts the disc 1 and the insulating plunger is subsequently forced back. Parts 405, 406, constitute a normally-closed switch 76, Fig. 2. Under normal running conditions with un-worn brakes, ignition switch terminal 63 is connected to contact 68 leading to an ignition coil (arrow N) and to bus 67, and switch 76 is closed. The base potential of transistor 77 is approximately zero and the transistor is in the cut-off state. The circuit is automatically tested on starting because terminal 63 is connected to contact 70 leading to the engine starter motor 69 and to the point between resistors 73, 74 (switch 76 still being closed), whereby base potential is applied to the transistor, which there-upon conducts so that lamp 78 lights up. On brake pad wear occurring (63 being connected to 68) switch 76 opens, whereupon base potential is again applied to the transistor, so lamp 78 lights up. In Figs. 4 and 6, where pad 112 besides covering one face of plate 113 occupies five holes 114, &c., provided in plate 113, a loop d, e, f, g, of insulated wire 127 is held against the end surface 123 of a hole 122 by a spring 135 forming part of a bracket 132. When, after pad wear, the exposed part of the loop is abraded and cut by disc 1. spring 135 pulls and separates the cut ends (which constitute the now-open switch 76). In Fig. 8, a spring contact 149 connected to insulated wire 151 is normally held against contact 150 connected to insulated wire 152 by a soft insert 156 (or part of the pad), but it springs out to position A on pad wear. In modifications of this arrangement: contact 149 is held by a projecting part on contact 150 and is released when disc 1 reaches and presses against contact 150; the wires form a closed loop linking two holes in the plate and when the exposed part of the loop is abraded and cut by disc 1 a coiled spring surrounding part of the loop pulls one cut end away from the other.

In the embodiment shown, air segments AS are introduced through tube 35 into the segmented sample stream in tube 34 prior to production of enlarged segments ASD at the junction of tubes 34 and 40. Air segments AR are similarly added through tube 37 to the second (dialysing liquid) stream 42. When a segment ASD reaches infra-red detector 100, a signal passed to delay timer 114 operates valve 46 after a predetermined time to produce a segment ASR, of substantially the same length as the segment ASD, in the dialysing liquid stream. The streams then pass through respective sides of dialyser 50, are optionally mixed with reagents, and pass through respective debubblers 56, 60 which remove all gas segments except ASD, ASR segments and remove part of the segments ASD, ASR; the streams then flow through colorimeters 68, 70. When the samples are blood samples, the total protein and calcium constituents of the respective streams may be measured.

Abstract: 1308904 Finishing fabrics NOVA (JERSEY) KNIT Ltd 26 March 1970 [14 Feb 1969] 8257/69 Headings D1C and D1S The uniformity of stitch density is restored to a tubular web of a knitted bulked polyester yarn which has become distorted after the knitting step by subjecting the web to substantially even tension across its width while maintaining it at the desired width and subjecting it to the action of vapour at a temperature below that at which heat setting of the web will occur, calendering the vapour treated web while maintaining it at the desired width and thereafter heat-setting the web. The yarn is preferably weft knitted and may be made of polyethylene terephthalate. After knitting the fabric, it is allowed to flow downwardly from the knitting elements to be collected as a flattened web in a container. The web is then twisted through 90‹ about its longitudinal axis to displace any centre crease by about 90‹, is passed over a roll and is gathered under gravity. The flattened fabric is overfed by conveyor rollers into a flat rectangular collar cooperating with a guide plate to maintain the fabric at the desired width. Vapour treatment of the fabric is effected in the collar. The vapour is superheated steam at a temperature below the temperature at which heat setting of the web will occur, i.e. below 150‹C and preferably 120-125‹C. After calendering, the fabric may be cut to open width, scoured, stentered and hydro-extracted. Alternatively, the open width fabric may be dry cleaned and then heat set. Heat setting may be carried out on stenters where the fabric is supported by air cushions or on perforated cylinders through which hot air is passed. The web is overfed into the heat setting apparatus.

As described, a railway signalling lamp 1 comprises a normal filament 12 and an auxiliary filament 11 of higher power so as to accommodate for reduced optical efficiency; relay 5 being normally energized by current through the main filament 12 so as to connect an auxiliary load 4 across part of the secondary winding of transformer 2. Failure of filament 12 results in release of relay 5 which de-energizes auxiliary load 4 and energizes auxiliary filament 11. Failure of filament 11 results in release of relay 3, so that contacts 31 give an indication of lamp failure. Auxiliary load 4 should consume the same power as the difference between the powers of filaments 11 and 12. In Fig. 2 (not shown) resistor 4 is omitted and a further resistor connected in series with filament 11 so as to form an auxiliary load but the resistor is by-passed by back contacts of relay 5 upon failure of filament 12 so that filament 11 takes over.

Abstract: 1341421 Multi-car elevator system OTIS ELEVATOR CO 18 May 1971 15638/71 Heading B8L In a three car system serving seven floors, in which the cars a, b, c are regarded as moving in a ring 1-6 UP-TOP-2 DOWN, the duty time required for a given car to serve hall calls and its own car calls between it and the next car ahead in the ring is continuously calculated, allowing for transit time between floors, as well as a definite time allotment for hall, or car calls, as the cars move, Figs. 2-5, Fig. 11 (not shown). The duty times for all cars are averaged, and should the duty time of a succeeding car on the ring be below average by a predetermined amount, which may be zero, the preceding car provided that it is not empty, is conditioned to by-pass hall calls which thus become allotted to the succeeding car. Alternatively, if the duty time of the preceding car exceeds the average by a predetermined amount, possibly zero, it may be conditioned to by-pass hall calls. The duty time may be automatically extended if the doors are re-opened during a call, for example by a proximity, or "open-door" switch. However, if a given hall call has existed for longer than a predetermined time, it will not be by-passed. Should the load on any one car exceed a predetermined proportion of its rated capacity it is removed from the group service, and answers its own car calls. Heavy demand.-When any one car b has a duty time more than twice the average, Fig. 20 (not shown), a scanning means is brought into operation, and selects another car which goes into a "direct service" mode, provided it is empty, the other cars receiving all hall calls, the "direct service" car answering at least one of the calls of the car b. Should the car behind b have a small duty time, car b may be conditioned to by-pass hall calls. A car may reverse at landings other than the upper and lower termini. Anti-coincidence arrangements.-An anti-coincidence circuit ensures that a trailing car answers a hall call, positions of cars being assessed only to the nearest landing, or the indicated car position is placed ahead of the actual car position as soon as it is indicated that a car will not stop at a given landing. Hall and car call registration.-Cold cathode tubes are used, Figs. 6, 7 (not shown). Car position measurement.-Floor contacts are engaged by the car, and ensure, for each floor, the firing of a thyristor, simultaneously with the quenching of the thyristor giving the previous position indication, Figs. 1, 1A (not shown). Should a load sensor, or absence of car calls, in a particular car indicate that it is empty, it will not be prevented from answering hall calls.
