Abstract: 847,483. Viscometers. READE, M. G. Feb. 8, 1957 [Feb. 22, 1956], No. 5501/56. Class 106 (2). Apparatus for determining the viscosity of fluids and semi-fluids comprises a set of hydrodynamically similar sinkers differing in size or weight, each sinker being attached to a length of wire, the wires each having two spaced-apart markers the distance between which is known. As described, the sinkers are in the form of spheres and the wires have loops at their upper ends to enable them to be handled easily. The time for a particular sinker to fall through the material under test is found and from this the apparent viscosity can be calculated.

IPC: G10C3/04
Filed: 1960-02-18
Abstract: 971,301. Pianofortes. CROWN FOUNDRY CO. Ltd. May 17, 1961 [Feb. 18,1960], No. 5800/60. Heading G4J. The frame of a piano and the top 1, bottom 4 and the sides 2, 3 of the casing are formed as an integral moulding of reinforced plastic. The frame includes a plank area 5, side members 6 and 7, a bottom 8 and struts 11, 12, 13, 14, 15. Glass cloth reinforcement is tailored and laid in the mould. An epoxy resin, a phenolic resin or a polyester is injected into the mould under pressure. Alternatively a vacuum process may be used. The structure is then cured. The struts may be reinforced by tubes of glass fibre. The tubes are formed by winding 45 degrees helices of fibre on a mandrel, layers being wound alternately in opposite directions. A wooden soundboard 52 is secured to the frame by screws 53. A wrest plank 22 of laminated beech is secured to the area 5 by screws 23. The wrest plank may be of plastic moulded integrally with the casing and the frame. The plastic wrest plank is formed or fitted with high friction plastic plugs to take the wrest pins 39. The wrest pins may be cast in the wrest plank. The integral moulding may also include an action rail 9 and a key bottom 10 carrying pivot pins 49 and guide pins 48.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1927-03-02
Abstract: 291,515. Automatic Telephone Manufacturing Co., Ltd., Ostline, J. E., Rayner, T. R., and Preist, T. P. March 2, 1927. Automatic exchange systems. - Busy tone is applied to both speaking leads in a switch in order that complete balance is obtained, and overhearing prevented; the tone is applied simultaneously or alternately with the flash signal which is obtained by applying the same potential to both leads. When a line reached by a connector, Fig. 2, is busy, contacts 15 - - 18 are closed to connect common busy signal apparatus to the switch. When the interrupter relay 22 is de-emergized, busy tone is connected from BT to both speaking leads, battery is connected to the lower winding of line relay 14 at contact 20, and battery is applied to the lower winding of release relay 6 at 21 to prevent the switch releasing. When relay 22 is energized, contacts 19, 21 are opened and contact 20 changes over to energize the line relay. In a modified connector, Fig. 3, contacts 24 - - 26 are operated when busy condition is met, and busy flash is applied simultaneously with busy tone through the windings of the line relay 23 by battery applied to the mid-point of the secondary of BT. In a further modification, Fig. 4, busy flash and busy tone are applied alternately, through resistances 31, 32, and since during busy flash, a local circuit is formed for the lower winding of line relay 30, no holding circuit is needed for the release relay. Selector circuits are also shown, in which the contacts connecting up the busy apparatus are cam-operated at the 11th contacts in the selector levels. One circuit is similar to that shown in Fig. 2, except that busy tone is connected to the line relay leads and busy tone and flash are alternate. In Fig. 7, busy tone is connected alternately with busy flash through a winding of the release relay 51 to a third winding on the line relay 55, and is sent over the speaking leads by induction. The connection through the release relay may be dispensed with if sufficient current is sent through the line relay to keep it always energized. A further modification similar to Fig. 4 is also shown in which a resistance is included in only one of the line relay leads, and the busy tone circuit is opened in the primary winding.

[Also in Groups I and XXIX] A water mixing tap comprises a body 3 formed with a cold water entry chamber 2 and an inlet 1 thereto for coupling this chamber to a water supply pipe, a cold water exit chamber 12 and an outlet 13 therefrom for coupling this chamber to a water outlet pipe, a passage interconnecting the entry and exit chambers controlled by a valve 7, and a hot water chamber 14 having an inlet 15 for connecting to a hot water supply pipe and being interconnected with the cold water entry chamber by a second - passage controlled by a valve 6. As shown in Fig. 2, the chamber 2 is connected to a main water supply via the inlet 1 so that by opening the valve 7 water passes through the chamber 12 and outlet 13. The latter outlet may be connected to the inlet of a water heater so that the hot water is then forced from the heater through the inlet 15 and chamber 14 and discharged through a spout 17. The valve 6 controls communication between the chamber 2 and an outlet chamber 16, the latter chamber also communicating with the spout. A dividing wall 19 may be included in the spout. In the construction shown in Figs. 8 and 9, the tap is arranged to be mounted on a sink top, the cold water supply being fed through pipe 26, chamber 22, valve 33, and pipe 29 to the water heater. Hot water then passes from the heater through inlet pipe 46, chamber 44, and spout 47. Cold water also passes from the chamber 22 through the spout via a second valve 38. The spout 47 is provided with a dividing wall 48.
