Title: Improvements in or relating to floor polishing machines
IPC: A47L11/18
Filed: 1925-11-23
Abstract: 244,735. Johnson & Son, S. C., (Assignees of Beach, C. H.). Dec. 19, 1924, [Convention date]. Floors, cleaning.-A floor polishing, cleaning, or sweeping machine comprises a pair of rotary brushes or rubbers 1, 2, mounted in a frame 4 and driven in opposite directions by gearing from an electromotor 5 secured to the frame, the bottoms of the brushes moving inwardly so that dust is directed towards a dust-pan 20 mounted on a central stationary brush 3. The latter is held in position by vertical pins 15 carried by a horizontal partition 14 beneath the motor, and is pressed down by springs 7. A crank 16 having an arm 17 and actuated from a handle 18 serves to remove the stationary brush from the pins when required. Each rotary brush is mounted on ball bearings on a stationary spindle 23 secured to the frame by screws 24. The machine is manipulated by a handle 6 which is secured to a yoke 28 connected to the frame by pivot pins 2 which are insulated from the frame and are connected by conductors 39 to a plug 37 and thence through a socket 38 to a conductor 41 which passes through the handle and carries a plug adapted to be connected to the mains. From the pivot pins the current passes to the motor through conductors 45, a switch 43 having a key 44 being included in the circuit. The pivots of the yoke are located so that in operation the machine is slightly tilted and thus the front brush assists in the forward movement of the machine while the rear brush assists in the backward movement. The Specification as open to inspection under Sect. 91 (3) (a) comprises also ball bearings, Fig. 6 (Cancelled), for supporting, the rotary brushes lubricant for the bearings being retained by end plates 26 and 27. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Speciftation 232,073.

Abstract: 158,440. British Northrop Loom Co., Ltd., (Northrop Loom Co.). Dec. 2, 1919. Shuttles, changing bobbins and other weft carriers in, automatically.-In a weft-replenishing mechanism of the type comprising a hopper 22, carrying bobbins or the like 20, which is rotated by a pawl 26, 27<x> on a transferrer 7, and is prevented from rotating backwards by a detent 31 on a pawl 29 engaging with a toothed disc 24, a detent 33 with a jaw 36 is fitted so as to engage with a pin 37 on the pawl 29 and to force the pawl 31 into close engagement with the teeth of the disc 24, thus rotating the hopper 22 forwards until the bobbin 20 nearest the stop 27 is brought into proper position for delivery by the transferrer 7 through the space 28 to the lay 18, or alternatively rotating the hopper backwards until the bobbin is moved back out of the path of the transferrer. If the pawl 31 engages with the top of a tooth, so that these movements are prevented, the detent 33 is positioned so as to engage with the upper surface of the shoulder 40 of the dog or finger 12; the bunter 17 is thus prevented from striking the dog 12 and moving the transferrer. If the pawl 31 engages correctly with the wheel 24, the detent 33 is moved by the dog or finger 12 as it is moved up by the slotted arm 15 on the part 16 of the shuttle feeler when the shuttle needs replenishment. The detent 33 then pushes the pawl 31 closely into the teeth of the wheel 24, and positions the hopper correctly. The notched end of the finger 12 then is in the path of the bunter 17 on the lay 18, and the transferrer 7 operates in the usual manner.

The carboxylic acid is in turn prepared by the inter-molecular esterification of a hydroxyalkanoic acid with a carboxylic acid which does not contain a hydroxyl group. Hydroxyalkanoic acids may be glycolic, lactic, hydracrylic and 12-hydroxystearic acid and the chain terminating acid may be an alkanoic acid equivalent to the hydroxyalkanoic acid, e.g. stearic acid. Examples describe the reaction of a poly-(hydroxystearic acid) with ethylene oxide. The compounds have surface active properties and may be used as dispersants for oil or petroleum resins in water. Examples describe the dispersion of crude oil in water.

Abstract: 1401203 Shift-register matrix stores TEXAS INSTRUMENTS Inc 27 June 1972 [19 July 1971 (2)] 30067/72 Heading G4C A matrix of storage cells A 1 -A n  to N 1 -N n  has a commutator circuit 14 (e.g. a shift register) for sequentially energizing row address lines, and, for each row of cells the read line is connected to the same address line as the write line of the adjacent row. Thus as one row is being written into from input lines IA-IN, the adjacent row is being read out on to output lines OA-ON. By connecting OA to IB, OB to IC and so on, the following, exemplary, shifts take place: A1 to Bn, A2 to B1, B4 to C3 whereby as data is written sequentially into column A and read sequentially from column N the rows of data in the intermediate columns are rotated in rows end around, and shifted to the right in columns. By including a 1-bit delay or storage element between the output line of one column and the input line of the next column, rotation of the rows is eliminated and the columns are shifted to the right, sequentially by bit as data is entered in column A and extracted from column N. MOST circuits are described.

Buckles. - In a suspender for stockings and the like, one end of an upper wire frame 27 is connected by a link 26 to a horizontal part 23 between the vertical parts 25 of a lower wire frame 20. The material 29 is inserted between the two frames, Fig. 2, and pressure is applied to the link 26 and frame 27 to cause the end 31 of the latter to .pass beneath the end 32 of the frame 20, Fig. 3, bends 28 on the frame 27 then lying over horizontal bends 22 in the frame 20. In this position, any pull on the material at 12 causes the material to press on the end 31 and displace the upper member rearwardly so as to clamp firmly the material between the two parts. The frame 20 and suspending loop 21 are formed from one piece of wire with its ends as eyes 24, 24<a>, engaging round the vertical parts 25, which, if desired, may be turned inwards over the eyes. The loop 21 instead of being shaped as shown in Fig. 1, may have an integral extension for attachment to pants &c., or may be formed with a hook.

Class 38(3) In Fig. 1, two identical three-phase synchronous motors 10, 10<SP>1</SP>, have deltaconnected stator windings 11, 11<SP>1</SP>, and unwqund rotors 14, 14<SP>1</SP>, respectively, the motors being mechanically coupled in driving relation to two devices to be operated in synchronism. The stator windings of the motors are connected in parallel through leads 22, 23, 24, so that the motors are started and operated in synchronism by connecting these leads directly to a three-phase supply through contacts 17, 20, of a three-position switch 16. To stop the motors, contacts 20 are engaged with contacts 19, the motors being supplied with reverse-current for braking. Impedances 25 limit the braking-current to a value below that required to start the motors from rest so that reversal does not take place after the motors have been brought to a standstill. The impedances 25 may be adjustable to vary the value of the braking-current. The permanent connections 22, 23, 24, are used to convey synchronizing current between the motors should they tend to fall out of step during periods of acceleration and deceleration. In Fig. 2, the motors may have deltawound rotors, two rotor terminals 31, 32, and 31<SP>1</SP>, 32<SP>1</SP>, on each motor being interconnected at 34, 34<SP>1</SP>, and leads 33, 35, connecting the rotor windings to a source of direct-current. If it is desired to operate the motors at sub-synchronous speeds, the stator and rotor windings are supplied with currents at different frequencies, the leads 33, 35, then being connected to a single-phase supply. The wound rotors of the motors may be supplied with both alternating and direct currents, the leads 34, 34<SP>1</SP>, being replaced by the centre-tapped secondary windings of a transformer, Fig. 3 (not shown).
