Abstract: 509,813. Window regulators. PERSSON, E. S. April 30, 1938, No. 12974. Convention date, Jan. 20. [Class 20 (iii)] A regulator for pivoted windows comprises a pin displaceable by means of a handle and which engages an open-ended slot whereby relative movement between the pin and the slot causes opening and closing movement of the window, yet permits the window to be freely opened beyond the position obtaining when the pin leaves the slot. In the construction shown, applied to a window pivoting about a horizontal axis, two rods 5, 6 located in the lower horizontal member of the fixed frame are moved laterally by means of a pinion 3 operated by a handle 4, each rod being provided with an upstanding pin 7 which engages in an inclined slot 12 formed in a metal plate 11 secured to the bottom sash-frame member. The slots 12 are inclined at about 45 degrees to the plane of the window, and the innermost ends thereof are open, in order that the window may be freely rotated when the pins 7 leave the ends of the slots. The rods 5, 6 are provided with extensions 20, formed with L-shaped slots 19, each of which is engaged by a pin 18 on a bracket 16 at the lower end of a vertical tubular member 15 in the stile of the window frame. During the concluding portion of the closing movement of the window, each of the members 15 is rotated into engagement with the adjacent sash stile.

Abstract: 1,245,320. Automatic exchange systems. TELEFONAKTIEBOLAGET L.M. ERICSSON. 17 Oct., 1969 [28 Oct., 1968], No. 51224/69. Heading H4K. In a computer controlled exchange having a data store containing a storage cell in respect of each peripheral equipment e.g. subscribers line, the equipments are arranged in groups that are scanned successively, the individual equipments of a group only being scanned if the group is marked as having one or more equipments that has or have changed its or their state since the last scan. The equipments' test points T11... Tmn each have an associated buffer store M11 ... Mmn which are arranged in groups G1 . . . Gm. In response to a change of state in an equipment, its buffer M is marked so as to temporarily stop a scanner V upon the group. Via multiple OR gate 02 the contents of the buffers in the group are entered in register Reg A. Simultaneously via OR gate 01 and decoder AVK, the contents of data store BA at the row corresponding to the marked group are read-out and inserted in Register B while a marking 1 bit MB is entered in the first column BA of the data store. This mark is noted by the central processor CPU during its periodic scanning of BA as an indication that a change of state has occurred in the corresponding row of BA, whereupon the row is read out and processed accordingly. Prior to this read-out however the change of state of the equipment must be recorded. This is effected by logic LC which compares the bits in Reg A and Reg B and alters the existing 0 or 1 state of the latter in respect of each 1 state present in Reg A. The resultant in Reg B is written back into the appropriate row of BA and scanning by scanner V is recommenced, the contents of Reg A being destroyed.

Title: Improvements in or relating to shoes
IPC: A43C15/16
Filed: 1968-10-29
Abstract: 1,243,258. Boots &c. E. T. WRIGHT & CO. Inc. 29 Oct., 1968 [3 June, 1968], No. 51245/68. Heading A3B. [Also in Division B5] A method of attaching studs 14 to shoe bottoms, e.g. of golf shoes, includes the steps of supporting the studs 14 with their heads adjacent the bottom of a lasted upper 28, forming a first layer p of dense plastisol against the bottom of the upper of such thickness to encompass the heads, allowing the plastisol to set and then forming a second layer p<SP>1</SP> of a less dense plastisol against the first layer leaving the tapered tips of the studs extending from the bottom of the second layer p<SP>1</SP>. The shoe bottom may be made by injecting the first layer p through a channel 30, lowering the sole plate 20 and injecting the second layer p<SP>1</SP> through channels 34, 36. Separate sole plates may be used for each moulding step, a first sole plate having recesses being used to form the first layer having bosses in which the heads of the studs are embedded, and the second sole plate being as shown in Fig. 2. The sole plate may be smaller than the shoe bottom and may be surrounded by a ring (not shown) which contacts the shoe bottom during the first moulding step and which is lowered during the second moulding step so that the second layer p<SP>1</SP> covers both the bottom and side edges of the first layer p. Alternatively the sole may be formed by injecting a plastisol containing a blowing agent under pressure to form the first dense layer p and, after this has set, moving the sole plate downwardly so that some of the plastisol expands to form the second layer p<SP>1</SP>. In a modification (Fig. 3) the studs are mounted in a pre-formed outsole S which is placed in the mould and plastisol is injected to complete the shoe bottom. The edge or top surface of the outsole S may have an undercut recess to improve the bond between the outsole and the plastisol.

Filed: 1964-12-21
Abstract: 1,026,598. Picture signal recording; telegraphy. FUJITSU Ltd. Dec. 21, 1964 [Dec. 21, 1963], No. 51959/64. Headings H4F and H4P. In a signal recording device in which a linear member 5 co-operates with a rotating helical member 15 to mark a paper tape 16 associated with an ink or carbon tape 17, the linear member is periodically raised by a multitooth cam 14 which coacts with a follower 4 and is allowed to fall to mark the tape 16 only when an electromagnet 1, which receives the signals to be recorded, is not energized. The signal power to operate the device is thus limited since the electromagnet serves only to hold the linear member in its raised position. The helical member makes one revolution for each recorded line across the tape and is stopped at the end of each revolution by a projection 13 which engages a stop 16. Each cycle of received signals corresponding to a recording line is preceded by a start signal which lifts the linear member (from a half raised position set by cam 14) to release stop 6 from projection 13, and is followed by stop signal which de-energizes electromagnet 1 to lower the stop into the path of the projection. The drive to the helical member is by way of a slipping clutch 11. The tape is advanced a short distance (by means not shown) after each revolution of the helical member. Reference is made to the use of the device for recording six-unit code signals and signals representing alpha-numeric information.

In a tubular heat exchanger WA, flue gases to be cooled, e.g. from a refuse incinerator (see Fig. 2, not shown), pass upwardly through a plurality of vertical tubes 3 mounted between end plates 2, 2<SP>1</SP> in a casing 1 and are cooled by two independent parallel streams of cooling air provided by fans 13, 17 flowing transversely across the tubes 3 in the casing from respective inlet connections 6, 6<SP>1</SP> to respective outlet connections 5, 5<SP>1</SP>. A transverse partition 7 subdivides the casing into two. A regulating device 16, e.g. a multiple damper, positioned upstream of the fan 17 controls the volume flow rate of cooling air fed through the casing via the inlet 6 in dependence of the outlet temperature of the cooled flue gases measured at 11 to keep said temperature within prescribed narrow limits. The regulating device alternatively may be a variable speed motor for the fan 17. The heated cooling air streams 14, 14<SP>1</SP> leaving the casing are either fed as hot underblast to the combustion grate (102, Fig. 2) of the incinerator or discharged into the atmosphere. Secondary cold air (109) may be added to the flue gases in the refuse incinerator to reduce their temperature prior to said flue gases entering the heat exchanger WA. As shown in Fig. 3b each tube may have transverse heat transfer fins 201 welded at regularly spaced intervals along-its length.
