[Also in Division A4] A grilling and dough proofing apparatus comprises a first flat horizontal grill member 20, an adjacent flat plate member (34), a second downwards forcing grill member 80, the plate (34) and second grill member being relatively reciprocatable by means of a counterweight system, a push bar 152 for shifting an assembly of forming rings containing dough 115 from the first grill member 20 to the plate (34), and a cabinet for humidifying and proofing, which cabinet contains a source of warm air and means to receive the assemblies of forming rings on trays 125. The counterweight system comprises a counterweight (not shown) fixed by a cable around a sheave located on shaft 54, the shaft being linked by a crank arm to the reciprocating plate (34), the crank and counterweight tending to rotate shaft 54 in opposite directions but maintaining the plate normally in the upper position. The plate (34) may be lowered by turning a wheel 60 at one end of the shaft 54 and is maintained in its lower position by a latch system 75, 75<SP>1</SP>. A product receiving shelf adjacent to the reciprocating plate and a bar 148 to centre the ring assemblies on the first grill may be incorporated. After proofing in the trays 125, the rings of dough are placed on grill 20 and one side is cooked. The assembly is then pushed by bar 152 across on to plate (34) which is held in its lower positon and the plate is then raised to cook the other side of the rings under grill 86.

Abstract: 1,226,089. Valves. TITUS MFG. CORP. 6 May, 1969, No. 22963/69. Heading F2V. [Also in Division F4] A constant flow regulator comprises a hollow cylinder 40, a piston 45 mounted for axial movement on means 42 and adapted to move in response to a pressure difference across its opposite faces, spring means 51, 52, 53 biasing the piston 45 to one end of the cylinder, the cylinder wall having a series of orifices 56, 57, 58 of varying dimensions, whereby the position of the piston maintains constant flow discharge from the opposite end of the cylinder. High pressure air acts on the top face of the piston (in the direction of the arrows) and passes through the orifices into the cylinder 40 at the low pressure side. If the pressure difference across the faces of the piston increases, the piston moves to close off more orifices on the low pressure side and so regulate the air flow. A pair of plates 71, 72 are movable to cover some of the orifices. Concentric baffles 91 are provided to reduce the noise of the high velocity jet of air. A mixing box 10 (Fig. 1, not shown) is provided with a cylinder (22) and piston (not shown) which, under thermostatic control move the plate valves (27), (28) of the hot and cold air ducts. The mixed air then passes to the constant flow regulator. A by-pass valve, similar to the regulator 40, is provided with just one set of orifices.

Abstract: 1,232,262. Digital transmission systems. WESTERN ELECTRIC CO. Inc. 28 June, 1968 [29 June, 1967], No. 30849/68. Heading H4P. In a digital transmission system comprising a central station and a number of out-stations connected to a common line, the central station calls each out-station in cyclic sequence to determine whether the out-station is ready to receive a message. The indication returned by the out-station is stored. When the central station has a message to transmit it sends a calling and enabling signal to each out-station designated in the message heading provided that the corresponding stored indication shows that the out-station is ready. The circuits of the stations are described. The operational programme is as follows. The central station sends a call-initiation signal which readies all the outstations to receive subsequent calling signals. The next station in turn is now called. It returns a signal indicating whether or not it is ready to receive a message and whether or not it has a message to send to the central station. The results of these indications are listed below. (a) If the out-station has a message to-send the call cycle stops and the central station sends the address of the out-station, which responds by sending the message. When the central station receives the end of message signal it initiates a new calling cycle. (b) If the out-station has no message to transmit and if the central station has no message to transmit the next out-station is called. (c) If the central station has a message to send, the addresses to which it is to be sent are stored. If the called out-station has no message for the central station, the call is stopped. The central station now sends a signal which readies all the out-stations, and then sends in turn the address of each out-station that is both ready to receive a message (as shown by the stored indication) and is listed in the message heading. Each addressed out-station replies with an indication that it is still, or no longer, ready to receive a message. The addresses of those that are still ready are cancelled from the list of stored addresses, and the store ready/not ready to receive indications are updated. The central station now enables only those of the addressed out-stations that are still ready and sends the message to them, the message being sent to the remaining addressed out-stations when they become ready during subsequent call cycles. The end of message signal disables all the outstations and a new call cycle is initiated.

An ear-ring clamp comprises a base member 10 having a clamping member 14 pivotally mounted on a flat plate portion 13, at one end of the base member, an ornament receiving portion 11 being at the other end of the base member 10; lugs 21 of the member 14 frictionally engage plate portion 13, the upper ends of the lugs being angled towards each other to give a resilient frictional grip which is variable dependent on the area of contact between the lugs 21 and the plate 13. Since the member 14 can be adjusted to any position, the clamping force on an ear can be varied to any desired value. Member 14 is pivotally mounted by detents 22 engaging with recesses in plate 13. Alternatively, the plate portion can be on the clamping member and the lugs on the base member.
